FORWARD-LOOKING STATEMENTS

This Annual Report on Form 20-F for the year ended December 31, 2022 (this “Annual Report”) contains certain forward-looking statements concerning plans and objectives of management for future operations or economic performance, or assumptions related thereto, including our financial forecast. In addition, we and our representatives may from time to time make other oral or written statements that are also forward-looking statements. Such statements include, in particular, statements about our plans, strategies, business prospects, changes and trends in our business, and the markets in which we operate as described in this Annual Report. In some cases, you can identify the forward-looking statements by the use of words such as “may,” “could,” “should,” “would,” “expect,” “plan,” “anticipate,” “intend,” “forecast,” “believe,” “estimate,” “predict,” “propose,” “potential,” “continue” or the negative of these terms or other comparable terminology. These forward-looking statements reflect management’s current views only as of the date of this Annual Report and are not intended to give any assurance as to future results. As a result, unitholders are cautioned not to rely on any forward-looking statements.

Forward-looking statements appear in a number of places in this Annual Report and include statements with respect to, among other things:

Table of Contents

Forward-looking statements in this Annual Report are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties, including those risks discussed in “Item 3. Key Information—Risk Factors.” The risks, uncertainties and assumptions involve known and unknown risks and are inherently subject to significant uncertainties and contingencies, many of which are beyond KNOT Offshore Partners’ control. KNOT Offshore Partners cautions that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

KNOT Offshore Partners undertakes no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible to predict all of these factors. Further, KNOT Offshore Partners cannot assess the impact of each such factor on its business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement. KNOT Offshore Partners makes no prediction or statement about the performance of its common units. The various disclosures included in this Annual Report and in KNOT Offshore Partners’ other filings made with the Securities and Exchange Commission (the “SEC”) that attempt to advise interested parties of the risks and factors that may affect KNOT Offshore Partners’ business, prospects and results of operations should be carefully reviewed and considered.

Risks Inherent in Our Business

We may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses to enable us to continue to pay distributions on our common units or Series A Preferred Units.

We may not have sufficient cash from operations to continue to pay distributions on our common units. Furthermore, distributions to the holders of our common units are subject to the prior distribution rights of any holders of our preferred units outstanding. As of March 30, 2023, there were 3,541,666 Series A Preferred Units issued and outstanding. Under the terms of our partnership agreement, we are prohibited from declaring and paying distributions on our common units until we declare and pay (or set aside for payment) full distributions on the Series A Preferred Units. The amount of cash we can distribute on our units principally depends upon the amount of cash we generate from our operations. On January 11, 2023, we reduced our quarterly common unit distribution to $0.026 per unit for the fourth quarter of 2022. Cash flows from operations may fluctuate from quarter to quarter based on the risks described in this section, including, among other things:

In addition, the actual amount of cash we have available for distribution depends on other factors, including:

The amount of cash we generate from our operations may differ materially from our profit or loss for the period, which is affected by non-cash items. As a result of this and the other factors mentioned above, we may make cash distributions during periods when we record losses and may not make cash distributions during periods when we record net income.

Table of Contents

On January 11, 2023, we reduced our quarterly common unit distribution rate to $0.026 per unit. Future distributions may remain at this level for an indefinite period or be eliminated entirely, which could impact our ability to raise capital.

Starting with the fourth quarter of 2022, we reduced our quarterly cash distribution to our common units to $0.026 per unit. We expect to continue to use our internally generated cash flow to provide for working capital, reduce our debt levels and strengthen our balance sheet. This reduction could have a negative impact on our unit price. Any negative impact on our unit price could ultimately impact our ability to raise capital.

Our ability to grow and to meet our financial needs may be adversely affected by our cash distribution policy.

Our cash distribution policy, which is consistent with our partnership agreement, requires us to pay the distribution on our Series A Preferred Units, which rank senior to our common units, and then to distribute all of our available cash (as defined in our partnership agreement) each quarter. Accordingly, our growth may not be as fast as businesses that reinvest their available cash to expand ongoing operations.

In determining the amount of cash available for distribution, our board of directors approves the amount of cash reserves to set aside, including reserves for future capital expenditures, working capital and other matters. We also rely upon external financing sources, including commercial borrowings, to fund our capital expenditures. Accordingly, to the extent we do not have sufficient cash reserves or are unable to obtain financing, our cash distribution policy may significantly impair our ability to meet our financial needs or to grow.

We must make substantial capital expenditures to maintain the operating capacity of our fleet, which reduces cash available for distribution.

We must make substantial capital expenditures to maintain, over the long-term, the operating capacity of our fleet. Capital expenditures include expenditures associated with the removal of a vessel from the water for inspection, maintenance and/or repair of submerged parts (or drydocking) and modifying an existing vessel or acquiring a new comparable vessel to the extent these expenditures are incurred to maintain or replace the operating capacity of our fleet. These expenditures could vary significantly from quarter to quarter and could increase as a result of changes in:

The required drydocking of our vessels could be more expensive and time consuming than we anticipate, which could adversely affect our cash available for distribution to unitholders.

We must periodically drydock each of our vessels for inspection, repairs and maintenance and any modifications required to comply with industry certification or governmental requirements. Generally, we drydock each vessel every 60 months until the vessel is 15 years old and every 30 months thereafter. The required drydocking of our vessels could be more expensive and time consuming than we anticipate, which could adversely affect our cash available for distribution. The drydocking of our vessels requires significant capital expenditures and results in loss of revenue while our vessels are off-hire. Any significant increase in the number of days of off-

10

Table of Contents

hire due to such drydocking or in the costs of any repairs could have a material adverse effect on our ability to pay distributions to our unitholders. If more than one of our vessels is required to be out of service at the same time, if a vessel is drydocked longer than expected or if the cost of repairs during drydocking is greater than budgeted, our cash available for distribution to unitholders could be adversely affected. In 2022, we experienced a total of approximately 387 offhire days due to the scheduled drydocking of six of our vessels. In 2023, we anticipate we will incur at least 156 offhire days as a result of the scheduled drydocking of five additional vessels.

We may be unable to charter our vessels or re-charter our vessels upon termination or expiration of their existing charters.

We are dependent upon charters for our vessels to generate revenues and we may be adversely affected if we fail to charter our vessels, fail to renew or are unsuccessful in winning new charters, or if our existing charters are terminated. Our ability to charter our vessels and the rates payable under our charters depends upon, among other things, the state of the shuttle tanker market. For example, an oversupply of shuttle tankers can reduce the charter rates that we can receive. On January 11, 2023, we reduced our quarterly common unit distribution to $0.026 per unit due in part to our inability to secure additional charter coverage for certain of our vessels at an acceptable rate. As of March 30, 2023, our vessels Bodil Knutsen, Hilda Knutsen and Torill Knutsen are currently on hire to an affiliate of KNOT at a reduced rate and up to five vessels (including Hilda Knutsen and Torill Knutsen) have charters that expire in or at the end of 2023 and which currently have no firm charters beyond that time. A failure to charter our vessels, a termination or renegotiation of our existing charters or a failure to secure new employment at the expiration of our current charters may have a negative effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

If capital expenditures are financed through cash from operations or by issuing securities, our ability to make cash distributions may be diminished, our financial leverage could increase, or our unitholders may be diluted.

Use of cash from operations to expand or maintain our fleet reduces cash available for distribution to unitholders. Our ability to obtain bank financing or to access the capital markets for future offerings may be limited by our financial condition at the time of any such financing or offering as well as by adverse market conditions resulting from, among other things, general economic conditions and contingencies and uncertainties that are beyond our control. Our failure to obtain the funds for future capital expenditures could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Even if we are successful in obtaining necessary funds, the terms of such financings could limit our ability to pay cash distributions to unitholders. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing additional equity securities may result in significant unitholder dilution and would increase the aggregate amount of cash required to maintain our current level of quarterly distributions to unitholders, both of which could have a material adverse effect on our ability to make cash distributions.

Our debt levels may limit our flexibility in obtaining additional financing, refinancing credit facilities upon maturity, pursuing other business opportunities or paying distributions.

As of December 31, 2022, we had consolidated debt of approximately $1,062.6 million, all of our revolving credit facilities had been fully drawn and we have no ability to incur additional debt under our credit facilities. If we acquire additional vessels or businesses, our consolidated debt may significantly increase. We may incur additional debt under future credit facilities. Furthermore, our $320 million senior secured credit facility and $55 million revolving credit facility secured by the Windsor Knutsen, Bodil Knutsen, Fortaleza Knutsen, Recife Knutsen, Carmen Knutsen and Ingrid Knutsen mature in September 2023 and our $172.5 million senior secured loan facility secured by the Dan Cisne and Dan Sabia matures in September 2023 and January 2024. Finally, our two $25 million unsecured revolving credit facilities mature in August 2023 and November 2023. Although we have commenced discussions with our lending group and other institutions and advisors concerning the refinancing of these credit facilities, no assurance can be given that such refinancing will be available on acceptable and similar terms. Global credit markets have been distressed recently and the related uncertainty in the financial services sector as well as certain lenders exiting the shipping sector could result in reduced access to credit. Please read “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.” Our level of debt could have important consequences to us, including the following:

11

Table of Contents

Our ability to service or refinance our debt depends upon, among other things, our current and future financial and operating performance, which is affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service or refinance our current or future indebtedness, we will be forced to take actions such as reducing distributions, reducing or delaying our business activities, acquisitions, investments or capital expenditures, selling assets, restructuring or refinancing our debt, or seeking additional equity capital or bankruptcy protection. We may not be able to effect any of these remedies on satisfactory terms, or at all.

Financing agreements containing operating and financial restrictions may restrict our business and financing activities.

The operating and financial restrictions and covenants in our financing agreements and any future financing agreements could adversely affect our ability to finance future operations or capital needs or to engage, expand or pursue our business activities. For example, the financing agreements may restrict the ability of us and our subsidiaries to:

In addition, our financing agreements require us to comply with certain financial ratios and tests, including, among others, maintaining a minimum liquidity, maintaining positive working capital, ensuring that our earnings before interest, taxes, depreciation and amortization (“EBITDA”) exceeds interest payable, maintaining a minimum collateral value, and maintaining a minimum book equity ratio. Our ability to comply with the restrictions and covenants, including financial ratios and tests, contained in our financing agreements is dependent on future performance and may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired.

If we are unable to comply with the restrictions and covenants in the agreements governing our indebtedness or in current or future debt financing agreements, there could be a default under the terms of those agreements. If a default occurs under these agreements, lenders could terminate their commitments to lend and/or accelerate the outstanding loans and declare all amounts borrowed due and payable. This could lead to cross-defaults under other financing agreements and result in obligations becoming due and commitments being terminated under such agreements. We have pledged our vessels as security for our outstanding indebtedness. If our lenders were to foreclose on our vessels in the event of a default, this may adversely affect our ability to finance future operations or capital needs or to engage in, expand or pursue our business activities. If any of these events occur, we cannot guarantee that our assets will be sufficient to repay in full all of our outstanding indebtedness, and we may be unable to find alternative financing. Even if we could obtain alternative financing, that financing might not be on terms that are favorable or acceptable. Any of

12

Table of Contents

these events would adversely affect our ability to make cash distributions to our unitholders and cause a decline in the market price of our common units. Please read “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.”

Restrictions in our debt agreements may prevent us or our subsidiaries from paying distributions.

The payment of principal and interest on our debt reduces cash available for distribution to us and on our units. In addition, our and our subsidiaries’ financing agreements prohibit the payment of distributions upon the occurrence of the following events, among others:

For more information regarding our financing agreements, please read “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.”

The failure to consummate or integrate acquisitions in a timely and cost-effective manner could have an adverse effect on our financial condition and results of operations.

Acquisitions that expand our fleet are an important component of our strategy. We believe that acquisition opportunities may arise from time to time, and any such acquisition could be significant. Any acquisition of a vessel or business may not be profitable after the time of acquisition and may not generate cash flows sufficient to justify the investment. In addition, our acquisition growth strategy exposes us to risks that may harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders, including risks that we may:

13

Table of Contents

In addition, unlike newbuilds, existing vessels typically do not carry warranties as to their condition. While we generally inspect existing vessels prior to purchase, such an inspection would normally not provide us with as much knowledge of a vessel’s condition as we would possess if it had been built for us and operated by us during its life. Repairs and maintenance costs for existing vessels are difficult to predict and may be substantially higher than for vessels we have operated since they were built. These costs could decrease our cash flows and reduce our liquidity.

Certain acquisition and investment opportunities may not result in the consummation of a transaction. In addition, we may not be able to obtain acceptable terms for the required financing for any such acquisition or investment that arises. We cannot predict the effect, if any, that any announcement or consummation of an acquisition would have on the trading price of our common units. Our future acquisitions could present a number of risks, including the risk of incorrect assumptions regarding the future results of acquired vessels or businesses or expected cost reductions or other synergies expected to be realized as a result of acquiring vessels or businesses, the risk of failing to successfully and timely integrate the operations or management of any acquired vessels or businesses and the risk of diverting management’s attention from existing operations or other priorities. We may also be subject to additional costs related to compliance with various international laws in connection with such acquisition. If we fail to consummate and integrate our acquisitions in a timely and cost-effective manner, our business, financial condition, results of operations and cash available for distribution could be adversely affected.

Our charters are subject to early termination under certain circumstances and any such termination could have a material adverse effect on our results of operations and cash available for distribution to unitholders.

As of March 30, 2023, our fleet consists of eighteen shuttle tankers. If our vessels are unable to generate revenues as a result of the expiration or termination of their charters or sustained periods of off-hire time, our results of operations and financial condition could be materially adversely affected. Each of our charters terminates automatically if the applicable vessel is lost or missing or damage to the vessel results in a constructive total loss. The customer, under certain circumstances, may also have an option to terminate a time charter if the vessel is requisitioned by any government for a period of time in excess of the time period specified in the time charter or if at any time we are in default under the time charter. In addition, either party may usually terminate a charter in the event of the outbreak of war between specified countries. Under our bareboat charters, the charter is deemed terminated as of the date of any compulsory acquisition of the vessel or requisition for title by any governmental or other competent authority. For more information regarding the termination of our charters, please read “Item 4. Information on the Partnership—Business Overview—Charters—Termination.”

We may experience operational problems with vessels that reduce revenue and increase costs.

Shuttle tankers are complex and their operation is technically challenging. Marine transportation operations are subject to mechanical risks and problems. Operational problems may lead to loss of revenue or higher than anticipated operating expenses or require additional capital expenditures. Any of these results could harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

We currently derive all of our time charter and bareboat revenues from nine customers, and the loss of any such customers could result in a significant loss of revenues and cash flow.

We currently derive all of our time charter and bareboat revenues from nine customers. For the year ended December 31, 2022, Fronape International Company, a subsidiary of Petrobras Transporte S.A. (“Transpetro”), Eni Trading and Shipping S.p.A. (“Eni”), Repsol Sinopec Brasil, S.A. (“Repsol”), Galp Sinopec Brazil Services B.V (“Galp”) and Brazil Shipping I Limited, a subsidiary of Royal Dutch Shell (“Shell”), accounted for approximately 17%, 14%, 14%, 6% and 5%, respectively, of our revenues.

If we lose a key customer, we may be unable to obtain replacement long-term charters and may become subject to the volatile spot market, which is highly competitive and subject to significant price fluctuations. In addition, if a customer exercises its right to terminate a charter, we may be unable to re-charter such vessel on terms as favorable to us as those of the terminated charter. The loss

14

Table of Contents

of any of our key customers could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Oil prices can be volatile, and this could affect the equity value of many of our customers. The combination of a reduction of cash flow resulting from lower prices, a reduction in borrowing under related credit facilities and the limited or lack of availability of debt or equity financing could potentially reduce the ability of our customers to make charter payments, which in turn could harm our business, results of operations and financial condition. Additionally, at the end of a contractual term we could lose one or more of our customers due to a variety of causes unrelated to our performance, including changes in customers’ management or strategic exits from the offshore oil space or from regions in which we operate.

We depend on subsidiaries of KNOT and its affiliates to assist us in operating our businesses and competing in our markets and chartering certain of our vessels.

We and our operating subsidiaries have entered into various services agreements with certain subsidiaries and affiliates of KNOT, including KNOT Management, KOAS and KOAS UK. Under these agreements these entities provide us with certain administrative, financial and other services. Our operating subsidiaries are provided with substantially all of their crew, technical and commercial management services (including vessel maintenance, periodic drydocking, cleaning and painting, performing work required by regulations and human resources and financial services) and other advisory and technical services, including the sourcing of new contracts and renewals of existing contracts. Our operational success and ability to execute our growth strategy depends significantly upon the satisfactory performance of these services by affiliates of KNOT. Our business will be harmed if such entities fail to perform these services satisfactorily or if they stop providing these services to us or our operating subsidiaries.

Our ability to compete to enter into new charters and expand our customer relationships depends largely on our ability to leverage our relationship with KNOT and its reputation and relationships in the shipping industry. If KNOT suffers material damage to its reputation or relationships, it may harm the ability of us or our subsidiaries to:

If our ability to do any of the things described above is impaired, it could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Furthermore, subsidiaries of KNOT currently charter three of our vessels. In 2022, subsidiaries of KNOT accounted for $14.5 million of our time charter revenues. If KNOT is unable to satisfy its obligations to us under such charters, it could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Our growth will primarily depend on continued growth in demand for shuttle tanker transportation services.

Our growth will primarily depend on continued growth in the demand for shuttle tanker transportation services. Factors beyond our control that affect the offshore oil transportation industry may have a significant impact on our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Fluctuations in the hire rate we can charge our customers result from changes in the supply of carrying capacity, production volumes of oil in the areas in which we operate and demand for the crude oil carried. If a sustained period of reduced demand for oil transportation services were to occur it would have a material adverse effect on our future growth and could harm our business, results of operations and financial condition. The factors affecting supply and demand for shuttle tankers and supply and demand for crude oil transported by shuttle tankers are largely outside of our control, and the nature, timing and degree of changes in industry conditions are unpredictable.

The factors that influence the supply of shuttle tanker capacity include, but are not limited to:

Persistent low oil prices may adversely affect our growth prospects and results of operations.

If there is a significant decline in oil prices that persists for a long period it may adversely affect our business, results of operations and financial condition and our ability to make cash distributions, as a result of, among other things:

Table of Contents

Our business is affected by macroeconomic conditions, including rising inflation, interest rates, market volatility, economic uncertainty and supply chain constraints.

Various macroeconomic factors could adversely affect our business and the results of our operations and financial condition, including changes in inflation, interest rates and overall economic conditions and uncertainties such as those resulting from the current and future conditions in the global financial markets. For instance, inflation has negatively impacted us by increasing crew and crew-related costs and through higher interest rates. Supply chain constraints have led to higher inflation, which if sustained could have a negative impact on our operations. If inflation or other factors were to significantly increase, our operations may be negatively affected. Interest rates, the liquidity of the credit markets and the volatility of the capital markets could also affect the operation of our business and our ability to raise capital on favorable terms, or at all, in order to fund our operations.

Increased inflation, including rising prices for items, such as raw materials, fuel, parts and components, freight, packaging, supplies, labor and energy increases the Partnership’s costs to provide services. The Partnership does not currently use financial derivatives to hedge against volatility in commodity prices. The Partnership uses market prices for materials, fuel, parts and components. Results of operations have been and, in the future, may be negatively affected if the Partnership is unable to mitigate the impact of these cost increases through contractual means and is unable to increase prices to sufficiently offset the effect of these cost increases.

Materials, components, and equipment essential to the Partnership’s operations are normally readily available, and shortages as a result of supply chain disruptions can adversely impact the Partnership’s operations, particularly where the Partnership has a limited number of suppliers. Many of the items essential to the Partnership’s business require the use of shipping services to transport them to the Partnership’s vessels or the applicable drydocking locations. Shipping delays or disruptions may result in operational slowdowns. These constraints could have a material adverse effect on the Partnership. In addition, price increases imposed by the Partnership’s vendors for materials and shipping services used in its business, and the inability to pass these increases through to its customers, could have a material adverse effect on the Partnership.

Throughout 2022, we experienced significant increases in the costs of fuel, logistics and crewing as a result of availability constraints, supply chain disruption, increased demand, labor shortages, inflation and other factors. Though we incorporated inflationary factors into our 2022 business plan, inflation outpaced those original assumptions and, while we have incorporated inflationary factors into our 2023 business plan, inflation may outpace those assumptions. These challenges are due in part to increased demand for oil and gas production driven by the continued economic recovery from the COVID-19 pandemic and more broadly, systemic underinvestment in global oil and gas development, together with general labor shortages. These supply and demand fundamentals have been further aggravated by disruptions in global energy supply caused by multiple geopolitical events, including the ongoing conflict between Russia and Ukraine. We continue to undertake actions and implement plans to strengthen our supply chain to address these pressures and protect the requisite access to commodities and services. Nevertheless, we expect for the foreseeable future to experience supply chain pressures and inflationary pressure on our cost structure. If we are unable to manage our global supply chain, it may impact our ability to hire and retain crew and procure materials and equipment in a timely and cost-effective manner, if at all, and, as a result, have a material adverse effect on our business, results of operations, cash flows, financial condition and ability to pay distributions to our unitholders.

Adverse conditions in the global economy or financial markets may impair our customers’ and suppliers’ ability to pay for our services and could have a material adverse effect on our revenue, profitability and financial position.

We depend on our customers’ willingness and ability to fund operating and capital expenditures to provide crude oil shuttle tankers for new or expanding offshore projects. Existing and future adverse economic conditions, including low oil prices, may lead to a decline in our customers’ operations or ability to pay for our services, which could result in decreased demand for our vessels. There has historically been a strong link between the development of the world economy and demand for energy, including oil and natural gas. Particularly, an extended period of adverse development in the outlook for the North Sea or Brazil could reduce the overall demand for our vessels and have a negative impact on our customers. Potential developments, or market perceptions concerning these and related issues, could affect our business, financial position, results of operations and ability to make cash distributions to our unitholders.

17

Table of Contents

Any regional or global financial or credit crisis or disruption may reduce the availability of liquidity and credit to fund the continuation and expansion of industrial business operations worldwide. Such deterioration could result in reduced demand for oil and natural gas, exploration and production activity and transportation of oil and natural gas that could lead to a decrease in the hire rate earned by our vessels and a decrease in new charter activity. In addition, any adverse development in the global financial markets or deterioration in economic conditions might adversely impact our ability to issue additional equity at prices that will not be dilutive to our existing unitholders or preclude us from issuing equity at all.

We also cannot be certain that additional financing will be available if needed and to the extent required, on acceptable terms or at all. Furthermore, certain banks that have historically been significant lenders to the shipping industry have reduced or ceased lending activities in the shipping industry. If additional financing is not available when needed, or is available only on unfavorable terms, we may be unable to meet our obligations as they come due or we may be unable to expand our existing business, complete shuttle tanker acquisitions or otherwise take advantage of business opportunities as they arise.

Furthermore, any uncertainty in the financial markets could have an impact on our customers and/or suppliers including, among other things, causing them to fail to meet their obligations to us. Similarly, any shortage of credit could affect lenders participating in our financing agreements, making them unable to fulfill their commitments and obligations to us. Any reductions in activity owing to such conditions or failure by our customers, suppliers or lenders to meet their contractual obligations to us could adversely affect our business, financial position, results of operation and ability to make cash distributions to our unitholders.

Our growth depends on our ability to expand relationships with existing customers and obtain new customers, for which we face substantial competition.

One of our principal objectives is to enter into additional long-term, fixed-rate charters. The process of obtaining new long-term charters is highly competitive, usually involving an intensive screening process and competitive bids. Shuttle tanker charters are awarded based upon a variety of factors relating to the vessel operator, including:

Our ability to win new charters depends upon a number of factors, including our ability to:

We expect substantial competition for providing services for potential shuttle tanker projects from a number of experienced companies. This increased competition may cause greater price competition for charters. As a result of these factors, we may be unable to expand our relationships with existing customers or to obtain new customers on a profitable basis, if at all, which would have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

An increase in the global supply of shuttle tanker capacity without a commensurate increase in demand may have an adverse effect on hire rates and the values of our vessels, which could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

The supply of shuttle tankers in the industry is affected by, among other things, assessments of the demand for these vessels. Any over-estimation of demand for vessels may result in an excess supply of shuttle tankers. Pandemic and other related delays to the start-up of offshore oil production, particularly in the North Sea and in the Norwegian sector, created an oversupply of shuttle tanker capacity at a time when we have multiple vessels coming back into the market, and which situation has also restricted the rates that are achievable for charter opportunities. This situation may also, in the long term, result in lower hire rates and depress the values of our vessels. Under such circumstances, our business, financial condition, results of operations and ability to make cash distributions to our unitholders may be adversely affected.

During periods of high utilization and high hire rates, industry participants may increase the supply of shuttle tankers by ordering the construction of new vessels. This may result in an over-supply of shuttle tankers and may cause a subsequent decline in utilization and hire rates when the vessels enter the market. Lower utilization and hire rates could adversely affect revenues and profitability. Prolonged periods of low utilization and hire rates could also result in the recognition of impairment charges on shuttle tankers if future cash flow estimates, based upon information available at the time, indicate that the carrying value of these shuttle tankers may not be recoverable. Such impairment charges may cause lenders to accelerate loan payments under our financing agreements, which could adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Compliance with safety and other vessel requirements imposed by classification societies may be very costly and may adversely affect our business.

The hull and machinery of every large, oceangoing commercial vessel must be classed by a classification society authorized by its country of registry. The classification society certifies that a vessel is safe and seaworthy in accordance with the applicable rules and regulations of the country of registry of the vessel and the International Convention for Safety of Life at Sea (“SOLAS”). All our vessels are certified either by DNV GL Group AS (“DNV GL”) or by the American Bureau of Shipping (“ABS”).

As part of the certification process, a vessel must undergo annual surveys, intermediate surveys and special surveys. In lieu of a special survey, a vessel’s machinery may be on a continuous survey cycle, under which the machinery would be surveyed periodically over a five-year period. Each of the vessels in our existing fleet is on a planned maintenance system approval, and as such the classification society attends onboard once every year to verify that the maintenance of the equipment onboard is done correctly. Each of the vessels in our existing fleet is required to be qualified within its respective classification society for drydocking once every five years subject to an intermediate underwater survey done using an approved diving company in the presence of a surveyor from the classification society.

If any vessel does not maintain its class or fails any annual survey, intermediate survey or special survey, the vessel will be unable to trade between certain ports and will be unemployable. We would lose revenue while the vessel was off-hire and incur costs of compliance. This would negatively impact our revenues and reduce our cash available for distribution to unitholders.

The value of our vessels may decline, which could adversely affect our operating results.

Vessel values for shuttle tankers can fluctuate substantially over time due to a number of different factors, including:

19

Table of Contents

If operation of a vessel is not profitable, or if we cannot redeploy a vessel at attractive rates upon termination of its charter, rather than continue to incur costs to maintain and finance the vessel, we may seek to dispose of it. Our inability to dispose of the vessel at a reasonable value could result in a loss on its sale and adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Additionally, lenders may accelerate loan repayments should there be a loss in the market value of our vessels. Such repayment could adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Further, if we determine at any time that a vessel’s future useful life and earnings require us to impair its value in our financial statements, we may need to recognize a significant charge against our earnings. We review vessels and equipment for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, which occurs when the asset’s carrying value is greater than the future undiscounted cash flows the asset is expected to generate over its remaining useful life.

Climate change concerns and greenhouse gas restrictions may adversely impact our operations and markets.

Due to concern over the risk of climate change, a number of countries and the International Maritime Organization (the “IMO”), the United Nations agency that regulates international shipping, have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions from vessels. These regulatory measures include, among others, adoption of cap and trade regimes, carbon taxes, increased efficiency standards and incentives or mandates for renewable energy. The Paris Agreement, which was announced by the Parties to the United Nations Framework Convention on Climate Change in December 2015, does not cover international shipping. However, in 2018, the IMO adopted an initial strategy designed to reduce the emission of greenhouse gases from vessels, including short-term, mid-term and long-term candidate measures with a vision of reducing and phasing out greenhouse gas emissions from vessels as soon as possible in the 21st century (“IMO GHG Strategy”). In November 2020, the Marine Environment Protection Committee (“MEPC”) of the IMO agreed to draft amendments to Annex VI of the 1973 International Convention for the Prevention of Pollution from Ships (“MARPOL”) that would establish an enforceable regulatory framework to reduce greenhouse gas emissions from international shipping, consisting of technical and operational carbon reduction measures. These measures include use of an Energy Efficiency Existing Ship Index, an operational Carbon Intensity Indicator and an enhanced Ship Energy Efficiency Management Plan to drive reductions in the carbon intensity. This regulatory approach is consistent with the IMO GHG Strategy target of a 40% carbon intensity reduction for international shipping by 2030, as compared to 2008. The draft MARPOL Annex VI amendments were adopted at the June 2021 MEPC session and, the Energy Efficiency Existing Ship Index and Carbon Intensity Indicator measures entered into force on January 1, 2023. Compliance with changes in laws, regulations and obligations relating to climate change could increase our costs related to operating and maintaining our vessels and require us to install new emission controls, acquire allowances or pay taxes related to our greenhouse gas emissions or administer and manage a greenhouse gas emissions program. Revenue generation and strategic growth opportunities may also be adversely affected.

We cannot predict whether or to what extent damage that may be caused by natural events, such as hurricanes, monsoons and other severe or catastrophic storms, will cause damage to our vessels and disruption to our operations and cause other adverse financial and operational impacts, including impacts on our customers. In particular, if one of the regions in which our vessels are operating is impacted by such a natural catastrophe in the future, it could have a material adverse effect on our business.

Adverse effects upon the oil industry relating to climate change, including growing public concern about the environmental and other impacts of climate change, may also adversely affect demand for our shuttle tanker services. Although we do not expect that demand for oil will lessen dramatically over the short or mid-term, in the long-term climate change mitigation considerations may reduce the demand for oil and increased regulation of greenhouse gases may create greater incentives for use of alternative energy sources. Any long-term material adverse effect on the oil industry could have a significant financial and operational adverse impact on our business that we cannot predict with certainty at this time.

Increased scrutiny from stakeholders and others regarding climate change, as well as our ESG practices and reporting responsibilities, could result in additional costs or risks and adversely impact our business and reputation

Companies across all industries have been subject to increasing scrutiny relating to their Environmental, Social and Governance ("ESG") policies. The investment community, including investment advisors and certain sovereign wealth, pension and endowment funds are increasingly focused on ESG practices and in recent years have placed growing importance on the implications and social cost of their investments. The increased focus and activism related to ESG and similar matters may hinder access to capital, as investors and lenders may decide to reallocate capital or not to commit capital as a result of their assessment of a company's ESG practices. Companies that do not adapt to or comply with investor, lender or other industry shareholder expectations and standards, which are evolving, or which are perceived to have not responded appropriately to the growing concern for ESG issues, regardless of whether there is a legal requirement to do so, may suffer from reputational damage and the business, financial condition or share price of such a company could be materially and adversely affected. Further, in recent years some in the investment community have promoted the divestment of fossil fuel equities and pressured lenders to cease or limit funding to companies engaged in the fossil fuel industry. Such initiatives aimed at limiting climate change and decarbonization could ultimately interfere with our business activities and operations and our access to capital. In addition to such initiatives, ESG matters more generally have been the subject of increased focus by investors, investment funds and other market and industry participants, as well as certain regulators, including in the U.S. and the EU.

We publish an annual Environment, Social and Governance Report (“ESG Report”) compiled in accordance with the Norwegian Shipowners’ Association’s ESG reporting guidelines. Our disclosures on ESG matters, a failure to meet the goals we establish or evolving stakeholder expectations for ESG practices and reporting may potentially harm our reputation and impact access to capital, customer or investor relationships, and employee retention. For example, some investors may use third-party benchmarks or scores to measure our ESG practices in making investment decisions and customers and suppliers may evaluate our ESG practices or require that we adopt certain ESG policies as a condition of awarding contracts. By electing to set and share publicly our corporate ESG standards, our business may also face increased scrutiny related to ESG activities. As ESG best-practices and reporting standards continue to develop, our costs related to ESG monitoring and reporting and complying with ESG initiatives may increase. In addition, it may be difficult or expensive for us to comply with any ESG-linked contracting policies adopted by customers and suppliers. Increased scrutiny from stakeholders and others regarding our ESG practices and reporting responsibilities (including our ESG Report) could result in additional costs or risks and adversely impact our business and reputation.

In addition, commitments made by us, or our customers, to reduce emissions, or decarbonize, may require us to upgrade or retrofit our vessels or operate them in a certain way. As a result, we may be required to take our vessels out of service for extended periods of time, with corresponding losses of revenues. Market conditions may not justify these expenditures or enable us to operate our vessels profitably.

Our international operations expose us to political, governmental and economic instability, which could harm our operations.

Our operations are conducted in various countries, and they may be affected by economic, political and governmental conditions in the countries where we engage in business or where our vessels are registered. Any disruption caused by these factors could harm our business, including by reducing the levels of oil exploration, development and production activities in these areas. We may derive some of our revenues from shipping oil from politically unstable regions. Conflicts in these regions have included attacks on ships and other efforts to disrupt shipping. Hostilities or other political instability in regions where we operate or where we may operate could have a material adverse effect on the growth of our business, financial condition, results of operations and ability to make cash distributions to our unitholders. In addition, tariffs, trade embargoes and other economic sanctions by the United States or other countries as a result of terrorist attacks, hostilities or otherwise may limit trading activities with those countries, which could also harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders. The Russian war with Ukraine, in addition to sanctions announced by President Biden and several European leaders against Russia and any forthcoming sanctions, may adversely impact our business. Finally, a government could requisition one or more of our vessels, which is most likely during war or national emergency. Any such requisition would cause a loss of the vessel and/or a termination of the charter and could harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Marine transportation is inherently risky, particularly in the extreme conditions in which our vessels operate. An incident involving significant loss of product or environmental contamination by any of our vessels could harm our reputation and business.

Vessels and their cargoes and the oil production facilities we service are at risk of being damaged or lost because of events such as:

Harsh weather conditions in the North Sea and other regions in which our vessels operate may increase the risk of collisions, oil spills or mechanical failures.

An accident involving any of our vessels could result in any of the following:

Any of these results could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders. In addition, any damage to, or environmental contamination involving, oil production facilities serviced could suspend that service and result in loss of revenues.

Our insurance may not be sufficient to cover losses that may occur to our property or as a result of our operations.

The operation of shuttle tankers is inherently risky. All risks may not be adequately insured against, and any particular claim may not be paid by insurance. Any claims relating to our operations covered by insurance would be subject to deductibles, and since it is possible that a large number of claims may be brought, the aggregate amount of these deductibles could be material. Certain insurance is maintained through mutual protection and indemnity associations (“P&I clubs”), and as a member of such associations we may be required to make additional payments over and above budgeted premiums if member claims exceed association reserves.

22

Table of Contents

We may be unable to procure adequate insurance at commercially reasonable rates in the future. For example, more stringent environmental regulations have led in the past to increased costs for, and in the future may result in the lack of availability of, insurance against risks of environmental damage or pollution. A catastrophic oil spill or marine disaster could exceed the insurance, and any uninsured or underinsured loss could harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders. In addition, the insurance may be voidable by the insurers as a result of certain actions, such as vessels failing to maintain certification with applicable maritime self-regulatory organizations.

Changes in the insurance markets attributable to terrorist attacks may also make certain types of insurance more difficult to obtain. In addition, the insurance that may be available may be significantly more expensive than existing coverage.

Terrorist attacks, piracy, increased hostilities or war could lead to further economic instability, increased costs and disruption of business.

Terrorist attacks, piracy and the current conflicts in Ukraine and the Middle East, and other current and future conflicts, may adversely affect our business, financial condition, results of operations and ability to raise capital and future growth.

The Russian war with Ukraine may lead to further regional and international conflicts or armed action. It is possible that such conflict could further disrupt supply chains and cause instability in the global economy. Additionally, the war could result in the imposition of further economic sanctions by the United States, the European Union and other nations against Russia. While much uncertainty remains regarding the global impact of the war, it is possible that an expansion of the conflict to other areas could adversely affect our business, financial condition, results of operation and cash flows. Furthermore, it is possible that third parties with whom we contract may be impacted by any such expansion of events in Russia and Ukraine, which could then adversely affect our operations.

Continuing hostilities in the Middle East may lead to additional armed conflicts or to further acts of terrorism and civil disturbance in the United States or elsewhere, which may contribute further to economic instability and disruption of oil production and distribution, which could result in reduced demand for our services.

In addition, oil production facilities, shipyards, vessels, pipelines, oil fields or other infrastructure could be targets of future terrorist attacks and our vessels could be targets of pirates or hijackers. Any such attacks could lead to, among other things, bodily injury or loss of life, vessel or other property damage, increased vessel operational costs, including insurance costs, and the inability to transport oil to or from certain locations. Terrorist attacks, war, piracy, hijacking or other events beyond our control that adversely affect the distribution, production or transportation of oil to be shipped by us could entitle customers to terminate their charters, which would harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Acts of piracy on ocean-going vessels could adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Acts of piracy have historically affected ocean-going vessels trading in regions of the world such as the South China Sea and the Gulf of Aden off the coast of Somalia. If such piracy attacks result in regions in which our vessels are deployed being named on the Joint War Committee Listed Areas, war-risk insurance premiums payable for such coverage could increase significantly and such insurance coverage might become more difficult to obtain. In addition, crew costs, including costs that may be incurred to the extent we employ onboard security guards, could increase in such circumstances. We may not be adequately insured to cover losses from these incidents, which could have a material adverse effect on us. In addition, hijacking as a result of an act of piracy against our vessels, or an increase in cost or unavailability of insurance for our vessels, could have a material adverse impact on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Vessels transporting oil are subject to substantial environmental and other regulations, which may significantly limit operations or increase expenses.

Our operations are affected by extensive and changing international, national and local environmental protection laws, regulations, treaties and conventions in force in international waters and the jurisdictional waters of the countries in which our vessels operate, as well as the countries of our vessels’ registration, including those governing oil spills, air emissions, discharges to water and the handling and disposal of hazardous substances and wastes. Many of these requirements are designed to reduce the risk of oil spills and other pollution. Additional requirements may take effect or be adopted in the future that could limit operations or further increase expenses. For example, under IMO’s MARPOL Annex VI, effective January 1, 2020, absent the installation of expensive sulfur scrubbers to meet reduced emission requirements for sulfur, the maximum sulfur content in fuels used by the marine sector in all seas, including our vessels, was lowered from 3.5% to 0.5% sulfur. These low sulfur fuel requirements are generally referred to as IMO 2020.

In addition, we believe that the heightened environmental, safety and security concerns of insurance underwriters, regulators and charterers will generally lead to additional regulatory requirements, including enhanced risk assessment and security requirements and greater inspection and safety requirements on vessels. These requirements are likely to add incremental costs to our operations and the failure to comply with these requirements may affect the ability of our vessels to obtain the required certificates for entry into the different ports where we operate and could also impact our ability to obtain insurance. We may incur substantial expenses in complying with these laws and regulations, including expenses for vessel modifications and changes in operating procedures.

These requirements can affect the resale value or useful lives of our vessels, require a reduction in cargo capacity, ship modifications or operational changes or restrictions, lead to decreased availability of insurance coverage for environmental matters or result in the denial of access to certain jurisdictional waters or ports or detention in certain ports.

Under local, national and foreign laws, as well as international treaties and conventions, we could incur material liabilities, including cleanup obligations, natural resource damage claims and fines and penalties in the event that there is a release of petroleum or hazardous substances from our vessels or otherwise in connection with our operations. We could also become subject to personal injury or property damage claims relating to the release of petroleum or hazardous substances associated with our operations. In addition, oil spills and failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of our operations, including, in certain instances, seizure or detention of our vessels. Please read “Item 4. Information on the Partnership—Business Overview—Environmental and Other Regulation.”

Exposure to currency exchange rate fluctuations results in fluctuations in cash flows and operating results.

Our reporting currency and the functional currency of our operating subsidiaries is the U.S. Dollar. Certain of our operating subsidiaries are party to technical management agreements with KNOT Management, which govern the crew, technical and commercial management of the vessels in our fleet. Under the technical management agreements, KNOT Management is paid for reasonable direct and indirect expenses incurred in providing the services, including operating expenses relating to our fleet. A majority of the operating expenses are in currencies other than the U.S. Dollar. Fluctuating exchange rates may result in increased payments by us under the services agreements if the strength of the U.S. Dollar declines relative to such other currencies.

Many seafaring employees are covered by collective bargaining agreements and the failure to renew those agreements or any future labor agreements may disrupt operations and adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

A significant portion of seafarers that crew certain of our vessels are employed under collective bargaining agreements. We and our operating subsidiaries may become subject to additional labor agreements in the future. We and our operating subsidiaries may suffer labor disruptions if relationships deteriorate with the seafarers or the unions that represent them. The collective bargaining agreements may not prevent labor disruptions, particularly when the agreements are being renegotiated. Salaries for seafarers are typically renegotiated annually or bi-annually, and higher compensation levels will increase our costs of operations. Although these negotiations have not caused labor disruptions in the past, any future labor disruptions could harm our operations and could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

KNOT may on our behalf be unable to attract and retain qualified, skilled employees or crew necessary to operate our business or may have to pay substantially increased costs for its employees and crew, including due to disruptions caused by a pandemic or other transmissible disease.

Our success depends in large part on KNOT’s ability to attract, hire, train and retain highly skilled and qualified personnel. In crewing our vessels, we require technically skilled employees with specialized training who can perform physically demanding work. Competition to attract, hire, train and retain qualified crew members is intense, and crew manning costs continue to increase. If we are not able to increase our hire rates to compensate for any crew cost increases, our business, financial condition, results of operations and ability to make cash distributions to our unitholders may be adversely affected. Furthermore, should there be a pandemic or an outbreak of a transmissible disease on board, adequate crewing my not be available to fulfill the obligations under our contracts. In such a situation we could face (i) difficulty in finding healthy qualified replacement officers and crew; (ii) local or international transport or quarantine restrictions limiting the ability to transfer infected crew members off the vessel or bring new crew on board; or (iii) restrictions in availability of supplies needed on board due to disruptions to third-party suppliers or transportation alternatives. Any inability we experience in the future to attract, hire, train and retain a sufficient number of qualified employees could impair our ability to manage, maintain and grow our business.

The COVID-19 pandemic continues to affect the global economy and energy demand and may adversely affect our business.

The outbreak and repercussions from the COVID-19 pandemic continues to affect global economic activity, including the demand for oil and oil shipping, which may materially impact the Partnership’s operations and the operations of its customers and suppliers.

Although there has been much progress in vaccinations and global economies appear to be recovering, potential impacts on the Partnership’s business, financial condition and results of operations remain, together with uncertainty in a number of areas of the Partnership’s business, including operational, commercial and financial activities.

The closure of, or restricted access to, ports and terminals and passenger air travel in regions affected by the virus could lead to further operational impacts that could result in higher costs. It is possible that a further outbreak onboard a time-chartered vessel could prevent the Partnership from meeting its obligations under a charter, resulting in an off-hire claim and loss of revenue.  Any outbreak of COVID-19 on board one of the Partnership’s time-chartered vessels or that affects any of the Partnership’s main suppliers could cause an inability to replace critical supplies or parts, maintain adequate crewing or fulfill the Partnership’s obligations under its time charter contracts, which in turn could result in off-hire or claims for the impacted period.

Announced delays in new capital expenditure by many oil majors in 2020 and 2021 had a negative impact on the demand for shuttle tankers. This affected the timing and number of new, offshore projects and overall oil production profiles in the short-term, which impacted the demand and pricing for shuttle tankers. If this situation persists, the Partnership may be unable to re-charter its vessels at attractive rates in the future, particularly for vessels that are coming off charter in the next one to two years.

The Partnership is exposed to the credit risk associated with individual charterers. Any extended period of idle time between charters or non-payment caused by issues related to COVID-19 or otherwise could adversely affect the Partnership’s future liquidity, results of operations and cash flows. Although the Partnership has not so far experienced any reduced or non-payments for obligations under the Partnership’s time charter contracts and the Partnership has not provided concessions or made changes to the terms of payment for customers, no assurance can be given that customers will continue to meet their obligations and will not request concessions or changes to payment terms in the future.

COVID-19 has also had a sustained impact on global capital markets. In these current market conditions, issuing new common equity remains a less viable and more expensive option for accessing liquidity. Approximately $280.9 million of the Partnership’s debt is due to be refinanced in the next twelve months. Although the Partnership expects to refinance its debt that falls due in 2023 as it matures, it may be unable to do so on satisfactory terms or on a timely basis. In such event, the Partnership may not have sufficient funds or other assets to satisfy all of its obligations, which would have a material adverse effect on its business, results of operations and financial condition.

Maritime claimants could arrest our vessels, which could interrupt our cash flow.

If we are in default on some kinds of obligations, such as those to our lenders, crew members, suppliers of goods and services to our vessels or shippers of cargo, these parties may be entitled to a maritime lien against one or more of our vessels. In many jurisdictions, a maritime lien holder may enforce its lien by arresting a vessel through foreclosure proceedings. In a few jurisdictions, claimants could try to assert “sister ship” liability against one vessel in our fleet for claims relating to another of our vessels. The arrest or attachment of one or more of our vessels could interrupt our cash flows and require us to pay to have the arrest lifted. Under some of our present charters, if the vessel is arrested or detained as a result of a claim against us, we may be in default of our charter and the charterer may terminate the charter. This would negatively impact our revenues and reduce our cash available for distribution to unitholders.

Lack of diversification and adverse developments in the shuttle tanker market or the conventional oil tanker market would negatively impact our results.

Although our vessels are also able to operate as conventional oil tankers, we are focused on using them as dynamic positioning shuttle tankers. Due to challenges in the North Sea shuttle tanker market, we have recently considered opportunities for our North Sea-based vessels in the conventional tanker market as a potential alternate source of income and employment. However, in practice, the all-in returns from conventional tanker employment may be insufficient once utilization and fuel costs are considered. Due to our lack of diversification, adverse developments in the shuttle tanker market and/or the conventional oil tanker market would have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

If in the future our business activities involve countries, entities and individuals that are subject to restrictions imposed by the U.S. or other governments, we could be subject to enforcement action and our reputation and the market for our common units could be adversely affected.

The tightening of U.S. sanctions in recent years has affected non-U.S. companies. In particular, sanctions against Iran have been significantly expanded. In 2012, for example, the U.S. signed into law the Iran Threat Reduction and Syria Human Rights Act of 2012 (“TRA”), which placed further restrictions on the ability of non-U.S. companies to do business or trade with Iran and Syria. A major provision in the TRA is that issuers of securities must disclose to the SEC in their annual and quarterly reports filed after February 6, 2013 if the issuer or “any affiliate” has “knowingly” engaged in certain activities involving Iran during the timeframe covered by the report. This disclosure obligation is broad in scope in that it requires the reporting of activity that would not be considered a violation of U.S. sanctions as well as violative conduct and is not subject to a materiality threshold. The SEC publishes these disclosures on its website and the President of the United States must initiate an investigation in response to all disclosures.

In addition to the sanctions against Iran, the U.S. also has sanctions that target other countries, entities and individuals. For example, sanctions announced by President Biden and several European nations against Russia and any forthcoming sanctions may adversely impact our business. These sanctions have certain extraterritorial effects that need to be considered by non-U.S. companies. It should also be noted that other governments have implemented versions of U.S. sanctions. For example, Norway, the EU and the United Kingdom have expanded restrictive measures against Russia and certain Russian businesses and individuals. We believe that we are in compliance with all applicable sanctions and embargo laws and regulations imposed by the U.S., Norway, the United Kingdom, the United Nations and EU countries and intend to maintain such compliance. However, there can be no assurance that we will be in compliance in the future, particularly as the scope of certain laws may be unclear and may be subject to changing interpretations. Any such violation could result in fines or other penalties and could result in some investors deciding, or being required, to divest their interest, or not to invest, in our common units. Additionally, some investors may decide to divest their interest, or not to invest, in our common units simply because we may do business with companies that do business in sanctioned countries. Investor perception of the value of our common units may also be adversely affected by the consequences of war, the effects of terrorism, civil unrest and governmental actions in these and surrounding countries.

Failure to comply with the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, the anti-corruption provisions in the Norwegian Criminal Code and other anti-bribery legislation in other jurisdictions could result in fines, criminal penalties, contract termination and an adverse effect on our business.

We may operate in a number of countries throughout the world, including countries known to have a high risk of corruption. We are committed to doing business in accordance with applicable anti-corruption laws and have adopted a code of business conduct and

Table of Contents

ethics. We are subject, however, to the risk that we, our affiliated entities or our or their respective officers, directors, employees and agents may take actions determined to be in violation of anti-corruption laws, including the U.S. Foreign Corrupt Practices Act of 1977, the Bribery Act 2010 of the Parliament of the United Kingdom and the anti-corruption provisions of the Norwegian Criminal Code of 1902. Any such violation could result in substantial fines, sanctions, civil and/or criminal penalties, curtailment of operations in certain jurisdictions, and might adversely affect our business, results of operations or financial condition. In addition, actual or alleged violations could damage our reputation and ability to do business. Furthermore, detecting, investigating, and resolving actual or alleged violations is expensive and could consume significant time and attention of our senior management.

A cyber-attack could materially disrupt our business.

We rely on information technology systems and networks, the majority of which are provided by KNOT Management, in our operations and the administration of our business. Our operations could be targeted by individuals or groups seeking to sabotage or disrupt our information technology systems and networks, or to steal data. A successful cyber-attack could materially disrupt our operations, including the safety of our operations, or lead to unauthorized release of information or alteration of information on our systems. Any such attack or other breach of our information technology systems could have a material adverse effect on our business, results of operations, financial condition, our reputation, or cash flows. We may be required to incur additional costs to modify or enhance our information technology systems or to prevent or remediate any such attacks.

The Russian war with Ukraine has been accompanied by cyber-attacks against the Ukrainian government and other countries in the region. It is possible that these attacks could have collateral effects on additional critical infrastructure and financial institutions globally, which could adversely affect the Partnership’s operations. It is difficult to assess the likelihood of such threat and any potential impact at this time.

Our business is subject to complex and evolving laws, directives and regulations regarding privacy and data protection.

We are subject to laws, directives, and regulations relating to the collection, use, retention, disclosure, security and transfer of personal data (“data protection laws”). These data protection laws, and their interpretation and enforcement, continue to evolve and may be inconsistent from jurisdiction to jurisdiction. For example, the General Data Protection Regulation (“GDPR”), which regulates the use of personally identifiable information, went into effect in the EU (“EU”) on May 25, 2018, applies globally to all of our activities conducted from an establishment in the EU, to related products and services that we offer to EU customers and to non-EU customers which offer services in the EU. Complying with the GDPR and similar emerging and changing data protection laws may cause us to incur substantial costs or require us to change our business practices. Noncompliance, or perceived noncompliance, with our legal obligations relating to data protection laws could result in penalties, fines, legal proceedings by governmental entities or others, loss of reputation, legal claims by individuals and customers and significant legal and financial exposure and could affect our ability to retain and attract customers. As noted above, we are also subject to the possibility of cyber attacks, which themselves may result in a violation of these laws.

Risks Inherent in an Investment in Us

KNOT and its affiliates may compete with us.

Pursuant to the omnibus agreement we entered into with KNOT at the time of our IPO (the “Omnibus Agreement”), KNOT and its controlled affiliates (other than us, our general partner and our subsidiaries) generally have agreed not to acquire, own, operate or charter certain shuttle tankers operating under charters of five years or more. The Omnibus Agreement, however, contains significant exceptions that may allow KNOT or any of its controlled affiliates to compete with us, which could harm our business. Please read “Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions—Omnibus Agreement—Noncompetition.”

Unitholders have limited voting rights, and our partnership agreement restricts the voting rights of Norwegian Resident Holders and unitholders owning more than 4.9% of our common units or Class B Units.

Unlike the holders of common stock in a corporation, holders of common units have only limited voting rights on matters affecting our business. The Class B Units generally vote together with the common units as a single class. We hold a meeting of the limited partners every year to elect one or more members of our board of directors and to vote on any other matters that are properly brought before the meeting. Common unitholders and holders of Class B Units (“Class B Unitholders”) are entitled to elect only four

27

Table of Contents

of the seven members of our board of directors. The elected directors are elected on a staggered basis and serve for four-year terms. Our general partner in its sole discretion appoints the remaining three directors and sets the terms for which those directors serve. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting our unitholders’ ability to influence the manner or direction of management. Unitholders have no right to elect our general partner, and our general partner may not be removed except by a vote of the holders of at least 66⅔% of the outstanding common units and Class B Units, including any common units and Class B Units owned by our general partner and its affiliates, voting together as a single class.

Our partnership agreement further restricts unitholders’ voting rights by providing that Norwegian Resident Holders are not eligible to vote in the election of elected directors. Further, if any person or group owns beneficially more than 4.9% of any class of units then outstanding (excluding Norwegian Resident Holders in the election of elected directors), any such units owned by that person or group in excess of 4.9% may not be voted on any matter and are not considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes (except for purposes of nominating a person for election to our board of directors), determining the presence of a quorum or for other similar purposes, unless required by law. The voting rights of any unitholders not entitled to vote on a specific matter are effectively redistributed pro rata among the other unitholders. Our general partner, its affiliates and persons who acquire common units or Class B Units with the prior approval of our board of directors are not subject to the 4.9% limitation except with respect to voting their common units or Class B Units in the election of the elected directors. The common units and the Class B Units will be treated as two separate classes of partnership interests for purposes of the 4.9% limitation, which will apply separately to the holders of common units and to the holders of Class B Units.

KNOT and its affiliates own a substantial interest in us and have conflicts of interest and limited fiduciary and contractual duties to us and our common unitholders, which may permit them to favor their own interests to the detriment of our unitholders.

As of March 30, 2023, KNOT owned 28.4% of our common units and all of our Class B Units, and owned and controlled our general partner, which owns a 1.83% general partner interest in us and 0.3% of our common units. Certain of our directors are directors of KNOT or its affiliates, and, as such, they have fiduciary duties to KNOT or its affiliates that may cause them to pursue business strategies that disproportionately benefit KNOT or its affiliates or which otherwise are not in the best interests of us or our unitholders. Conflicts of interest may arise between KNOT and its affiliates (including our general partner), on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, our general partner and its affiliates may favor their own interests over the interests of our unitholders. Please read “—Our partnership agreement limits our general partner’s and our directors’ fiduciary duties to our unitholders and restricts the remedies available to unitholders for actions taken by our general partner or our directors.” These conflicts include, among others, the following situations:

Although a majority of our directors have been elected by common unitholders, our general partner has substantial influence on decisions made by our board of directors. Please read “Item 7. Major Unitholders and Related Party Transactions.”

Our partnership agreement limits our general partner’s and our directors’ fiduciary duties to our unitholders and restricts the remedies available to unitholders for actions taken by our general partner or our directors.

Our partnership agreement provides that our general partner irrevocably delegates to our board of directors the authority to oversee and direct our operations, management and policies on an exclusive basis, and such delegation is binding on any successor general partner of the Partnership. Our partnership agreement also contains provisions that reduce the standards to which our general partner and directors would otherwise be held by Marshall Islands law. For example, our partnership agreement:

In order to become a limited partner of our partnership, a common unitholder is required to agree to be bound by the provisions in our partnership agreement, including the provisions discussed above.

Our partnership agreement provides that our general partner delegates all its management activities in relation to us to our board of directors, and arrangements are in place such that any activities that would otherwise constitute regulated activities under the

29

Table of Contents

Financial Services and Markets Act 2000 (Regulated Activities Order) 2001 were they to be performed in the United Kingdom (and that would not fall within a suitable exemption) are performed outside of the United Kingdom.

However, there can be no assurance that this will not change (deliberately or otherwise) over time, and there is no current intention for our general partner, us or any of our subsidiaries to seek authorization from the Financial Conduct Authority in the United Kingdom, which would be required for any person to lawfully carry out such regulated activities in the United Kingdom.

Fees and cost reimbursements, which affiliates of KNOT determine for services provided to us and our subsidiaries, are substantial, payable regardless of our profitability and reduce our cash available for distribution to our unitholders.

Pursuant to technical management agreements, our subsidiaries that own vessels operating under time charters pay fees for services provided to them by KNOT Management and reimburse KNOT Management for all expenses incurred on their behalf. These fees and expenses include all costs and expenses incurred in providing the crew, technical and commercial management of the vessels in our fleet to our subsidiaries. Additionally, our subsidiaries that own vessels operating under bareboat charters have entered into management and administration agreements with either KNOT Management or KNOT Management Denmark pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

In addition, pursuant to an administrative services agreement, KNOT UK provides us with certain administrative services. KNOT UK is permitted to subcontract certain of the administrative services provided to us under this agreement to KOAS UK, KOAS and KNOT Management. We reimburse KNOT UK, and KNOT UK reimburses KOAS UK, KOAS and KNOT Management, as applicable, for their reasonable costs and expenses incurred in connection with the provision of the services subcontracted to KOAS UK, KOAS and KNOT Management under the administrative services agreement. In addition, KNOT UK pays to KOAS UK, KOAS and KNOT Management, as applicable, a service fee in U.S. Dollars equal to 5% of the costs and expenses incurred in connection with providing services.

For a description of the technical management agreements, management and administration agreements and the administrative services agreement, please read “Item 7. Major Unitholders and Related Party Transactions.” The fees and expenses payable pursuant to the technical management agreements, management and administration agreements and the administrative services agreement are payable without regard to our business, results of operation and financial condition. The payment of fees to and the reimbursement of expenses of affiliates of KNOT could adversely affect our ability to pay cash distributions to our unitholders.

Our partnership agreement contains provisions that may have the effect of discouraging a person or group from attempting to remove our current management or our general partner, and even if public unitholders are dissatisfied, they are unable to remove our general partner without KNOT’s consent, unless KNOT’s ownership interest in us is decreased, all of which could diminish the trading price of our common units.

Our partnership agreement contains provisions that may have the effect of discouraging a person or group from attempting to remove our current management or our general partner.

Table of Contents

Unitholders’ voting rights are further restricted by our partnership agreement provision providing that if any person or group owns beneficially more than 4.9% of any class of units then outstanding, any such units owned by that person or group in excess of 4.9% may not be voted on any matter and are not considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes (except for purposes of nominating a person for election to our board of directors), determining the presence of a quorum or for other similar purposes, unless required by law. The voting rights of any such unitholders in excess of 4.9% effectively are redistributed pro rata among the other unitholders holding less than 4.9% of the voting power of all classes of units entitled to vote. Our general partner, its affiliates and persons who acquire common units or Class B Units with the prior approval of our board of directors are not subject to this 4.9% limitation except with respect to voting their common units or Class B Units in the election of the elected directors.

The effect of these provisions may be to diminish the price at which the common units trade.

The control of our general partner may be transferred to a third party without unitholder consent.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent of our unitholders. In addition, our partnership agreement does not restrict the ability of the members of our general partner from transferring their respective membership interests in our general partner to a third party.

Substantial future sales of our common units or the issuance of additional preferred units could cause the price of our common units to fall.

The market price of our common units could decline due to sales of a large number of units, or the issuance of debt securities or warrants, in the market, or the perception that these sales could occur. These sales could also make it more difficult for us to sell equity securities in the future at a time and price that we deem appropriate to raise funds through future offerings of common units.

We have granted registration rights to KNOT and certain of its affiliates. These unitholders have the right, subject to some conditions, to require us to file registration statements covering any of our common or other equity securities owned by them or to include those securities in registration statements that we may file for ourselves or other unitholders. As of March 30, 2023, KNOT and our general partner owned 28.6% of the common units and all of the Class B Units. We have also entered into a registration rights agreement with the holders of the Series A Preferred Units, pursuant to which we filed a registration statement to register resales of the common units underlying the Series A Preferred Units. Following their sale, these securities will become freely tradable. By exercising their registration rights and selling a large number of common units or other securities, our securityholders with registration rights could cause the price of our common units to decline.

Our common units are subordinated to our existing and future indebtedness and our Series A Preferred Units.

Our common units are equity interests in us and do not constitute indebtedness. The common units rank junior to all indebtedness and other non-equity claims on us with respect to the assets available to satisfy claims, including a liquidation of the Partnership. Additionally, holders of the common units are subject to the prior distribution and liquidation rights of the holders of the Series A Preferred Units and any other preferred units we may issue in the future.

As long as our outstanding Series A Preferred Units remain outstanding, distribution payments relating to our common units are prohibited under our partnership agreement until all accrued and unpaid distributions are paid on the Series A Preferred Units.

31

Table of Contents

We may issue additional equity securities, including a limited amount of securities senior to the common units, without the approval of our unitholders, which would dilute their ownership interests.

We may, without the approval of our unitholders, issue an unlimited number of additional common units. In addition, we may issue units that are senior to the common units in right of distribution, liquidation and voting, provided that the aggregate amount of our Series A Preferred Units and any other securities on parity with the Series A Preferred Units, pro forma for such issuance, does not exceed 33.33% of the book value of the sum of our then outstanding aggregate amount of parity securities and junior securities (including the common units). The consent of the holders of the Series A Preferred Units will be necessary for us to issue any parity securities (or securities senior to our Series A Preferred Units) in excess of such pro forma book value.

The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects:

A substantial number of our common units may be issued upon conversion of our Series A Preferred Units or Class B Units or as redemption payments in respect of our Series A Preferred Units, which issuances could reduce the value of our common units.

Our Series A Preferred Units are convertible, under certain circumstances, at the applicable conversion rate, which is subject to adjustment under certain circumstances. The conversion rate will be redetermined on a quarterly basis, such that the conversion rate will be equal to $24.00 (the “Issue Price”) divided by the product of (x) the book value per common unit at the end of the immediately preceding quarter (pro-forma for per unit cash distributions payable with respect to such quarter) multiplied by (y) the quotient of (i) the Issue Price divided by (ii) the book value per common unit on the initial issuance date of the Series A Preferred Units.

The Series A Preferred Units are generally convertible, at the option of the holders of the Series A Preferred Units, into common units at the then applicable conversion rate. In addition, we may redeem the Series A Preferred Units at any time before February 2, 2027 at the redemption price applicable on any such redemption date, provided, however, that upon notice from us to the holders of Series A Preferred Units of our intention to redeem, such holders may elect, instead, to convert their Series A Preferred Units into common units at the then applicable conversion rate. In addition, subject to certain conditions, we may convert the Series A Preferred Units into common units at the then applicable conversion rate. Upon a change of control of the Partnership, the holders of Series A Preferred Units may require us to redeem the Series A Preferred Units, in cash, at 100% of the Issue Price. Further, the holders of Series A Preferred Units may cause us to redeem the Series A Preferred Units on February 2, 2027 in, at our option, (i) cash at a price equal to 70% of the Issue Price or (ii) common units such that each Series A Preferred Unit receives common units worth 80% of the Issue Price. The value (and, therefore, the number) of the common units to be delivered pursuant thereto will be determined based on the volume-weighted average trading price, as adjusted for splits, combinations and other similar transactions, of our common units as reported on the NYSE for the 30-trading day period ending on the fifth trading day immediately prior to the redemption date.

The Class B Units are a class of limited partner interests which are not entitled to receive cash distributions in any quarter unless common unitholders receive a distribution of at least $0.52 for such quarter (the “Distribution Threshold”). When common unitholders receive a quarterly distribution at least equal to the Distribution Threshold, then Class B unitholders will be entitled to receive the same distribution as common unitholders. For each quarter (starting with the quarter ended September 30, 2021) that the Partnership pays distributions on the common units that are at or above the Distribution Threshold, one-eighth of the Class B Units will be converted to common units on a one-for-one basis until such time as no further Class B Units exist. As of March 30, 2023 a total of 420,675 of the Class B Units had converted to common units on a one-to-one basis.

Table of Contents

If a substantial portion of the Series A Preferred Units or the Class B Units are converted into common units, or the Series A Preferred Units are redeemed under certain circumstances, common unitholders could experience significant dilution. Furthermore, if holders of such Series A Preferred Units or Class B Units were to dispose of a substantial portion of these common units in the public market following such a conversion, whether in a single transaction or series of transactions, it could adversely affect the market price for our common units. These sales, or the possibility that these sales may occur, could make it more difficult for us to sell our common units in the future.

The number of our common units issuable upon conversion or redemption under certain circumstances of the Series A Preferred Units will be impacted by, among other things, the level of our quarterly cash distributions, as the conversion rate is redetermined each quarter, based on the pro forma per unit cash distributions we make on our common units (as described above) and the market price of our common units. Accordingly, the number of common units issuable upon conversion or redemption under certain circumstances could be substantial, especially during periods of significant declines in market prices of our common units or if we experience certain events, such as, among other things, a decline in the value of our vessels that results in an impairment or write-down of the value of our vessels or a write-off of any goodwill, decline in the fair value of our derivative instruments, change in accounting principle that results in a decline in our book value, or other event that results in a decline in our book value.

The issuance of common units upon conversion of our Series A Preferred Units or Class B Units or redemption under certain circumstances of our Series A Preferred Units may have the following effects:

The market price of our common units is likely to be influenced by the Series A Preferred Units and Class B Units. For example, the market price of our common units could become more volatile and could be depressed by:

Our Series A Preferred Units have rights, preferences and privileges that are not held by, and are preferential to the rights of, holders of our common units.

Our Series A Preferred Units rank senior to all our common units with respect to distribution rights and liquidation preference. These preferences could adversely affect the market price for our common units or could make it more difficult for us to sell our common units in the future.

In addition, distributions on the Series A Preferred Units accrue and are cumulative. Our obligation to pay distributions on our Series A Preferred Units, or on the common units issued following conversion of such Series A Preferred Units, could impact our liquidity and reduce the amount of cash flow available for working capital, capital expenditures, growth opportunities, acquisitions, and other general partnership purposes. Our obligations to the holders of Series A Preferred Units could also limit our ability to obtain additional financing or increase our borrowing costs, which could have an adverse effect on our financial condition.

Our general partner has a limited call right that may require our unitholders to sell their common units at an undesirable time or price.

If at any time our general partner and its affiliates own more than 80.0% of the common units and Class B Units, our general partner has the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than the then-current market price of our common units. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon the exercise of this limited call right. As a result, our unitholders may be required to sell their common units at an undesirable time or price and may not receive any return on their investment. Our unitholders may also incur a tax liability upon a sale of their units.

As of March 30, 2023, KNOT and our general partner owned 29.2% of our common units and Class B Units.

Our unitholders may not have limited liability if a court finds that unitholder action constitutes control of our business.

As a limited partner in a partnership organized under the laws of the Marshall Islands, our unitholders could be held liable for our obligations to the same extent as a general partner if our unitholders participate in the “control” of our business. Our general partner generally has unlimited liability for the obligations of the Partnership, such as its debts and environmental liabilities, except for those contractual obligations of the Partnership that are expressly made without recourse to our general partner. In addition, the limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in some jurisdictions in which we do business.

We can borrow money to pay distributions, which would reduce the amount of credit available to operate our business.

Our partnership agreement allows us to make working capital borrowings to pay distributions. Accordingly, if we have available borrowing capacity, we can make distributions on all our units even though cash generated by our operations may not be sufficient to pay such distributions. Any working capital borrowings by us to make distributions reduces the amount of working capital borrowings we can make for operating our business. For more information, please read “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.”

Increases in interest rates may cause the market price of our common units to decline.

An increase in interest rates may cause a corresponding decline in demand for equity investments in general, and in particular for yield-based equity investments such as our common units. Any such increase in interest rates or reduction in demand for our common units resulting from other relatively more attractive investment opportunities may cause the trading price of our common units to decline.

We are exposed to market risks relating to the announced phase-out of the London Interbank Offered Rate (“LIBOR”).

We are exposed to a market risk relating to increases in interest rates because the amounts borrowed under our existing loan and credit facilities bear interest at rates based on LIBOR. The publication of LIBOR for the one-week and two-month U.S. Dollar LIBOR tenors ceased on December 31, 2021, and the ICE Benchmark Administration, the administrator of LIBOR, with the support of the United States Federal Reserve and the United Kingdom’s Financial Conduct Authority, announced that the publication of all other LIBOR tenors will cease on June 30, 2023. Significant increases in LIBOR or uncertainty surrounding its phase out after June 30, 2023 could adversely affect our business, financial condition, operating results and cash flows. The outcome of reforms may result in increased interest expense to us, may affect our ability to incur debt on terms acceptable to us and may result in increased costs related to amending our existing debt instruments, which could adversely affect our business, results of operations and financial condition. We use interest rate swaps to reduce our exposure to interest rate risk and hedge a portion of our outstanding indebtedness. There is no assurance that our derivative contracts will provide adequate protection against adverse changes in interest rates or that our bank counterparties will be able to perform their obligations.

Although we intend to agree an alternative, market acceptable, basis with the lenders under our credit facilities, and with the counterparties under our derivative instruments, to replace the applicable LIBOR rates with rates based on the Secured Overnight Financing Rate (“SOFR”) or another alternative reference rate , there can be no assurance that we will be able to reach agreement on favorable terms or at all. We have an engagement plan, and we are actively engaging with our counterparties to reach agreement on an

34

Table of Contents

alternative basis. Any agreement on an alternative benchmark rate may however negatively impact the value of our credit facilities or derivative instruments, may expose us to additional financial, tax, legal, operational or other costs, or expose us to additional interest rate-related risks, such as different alternative reference rates.

We rely on the master limited partnership (“MLP”) structure and its appeal to investors for accessing debt and equity markets to finance our growth and repay or refinance our debt. The volatility in energy prices over the past few years has, among other factors, caused increased volatility and contributed to a dislocation in pricing for MLPs.

The volatility in energy prices and, in particular, the price of oil, among other factors, has contributed to increased volatility in the pricing of MLPs and the energy debt markets. A number of MLPs, including us and certain other maritime MLPs, have reduced or eliminated their distributions to unitholders.

We rely on our ability to obtain financing and to raise capital in the equity and debt markets to fund our capital replacement, growth and investment expenditures, and to refinance our debt. A protracted deterioration in the valuation of our common units would increase our cost of capital, make any equity issuance significantly dilutive and may affect our ability to access capital markets and, as a result, our capacity to pay distributions to our unitholders and service or refinance our debt.

Unitholders may have liability to repay distributions.

Under some circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under the Marshall Islands Limited Partnership Act (the “Marshall Islands Act”), we may not make a distribution to our unitholders if the distribution would cause our liabilities, other than liabilities to partners on account of their partnership interest and liabilities for which the recourse of creditors is limited to specified property of ours, to exceed the fair value of our assets, except that the fair value of property that is subject to a liability for which the recourse of creditors is limited will be included in our assets only to the extent that the fair value of that property exceeds that liability. Marshall Islands law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Marshall Islands law will be liable to the limited partnership for the distribution amount. Assignees who become substituted limited partners are liable for the obligations of the assignor to make contributions to the limited partnership that are known to the assignee at the time it became a limited partner and for unknown obligations if the liabilities could be determined from our partnership agreement.

We have been organized as a limited partnership under the laws of the Marshall Islands, which does not have a well-developed body of partnership law.

Our partnership affairs are governed by our partnership agreement and by the Marshall Islands Act. The provisions of the Marshall Islands Act resemble provisions of the limited partnership laws of a number of states in the United States, most notably Delaware. For non-resident limited partnerships such as ours, the Marshall Islands Act also provides that it is to be applied and construed to make it, with respect to the subject matter thereof, uniform with the laws of the State of Delaware and, so long as it does not conflict with the Marshall Islands Act or decisions of the High and Supreme Courts of the Marshall Islands, the non-statutory law (or case law) of the State of Delaware is adopted as the law of the Marshall Islands. There have been, however, few, if any, court cases in the Marshall Islands interpreting the Marshall Islands Act, in contrast to Delaware, which has a fairly well-developed body of case law interpreting its limited partnership statute. Accordingly, we cannot predict whether Marshall Islands courts would reach the same conclusions as the courts in Delaware. For example, the rights of our unitholders and the fiduciary responsibilities of our general partner under Marshall Islands law are not as clearly established as under judicial precedent in existence in Delaware. As a result, unitholders may have more difficulty in protecting their interests in the face of actions by our general partner and its officers and directors than would unitholders of a similarly organized limited partnership in the United States.

Because we and KNOT UK are Marshall Islands entities, our operations are subject to economic substance requirements, which could harm our business.

The Council of the European Union, or the Council, routinely publishes a list of “non-cooperative jurisdictions” for tax purposes, which includes countries that the Council believes need to improve their legal framework and to work towards compliance with international standards in taxation. On February 14, 2023, the Republic of the Marshall Islands, among others, was placed by the EU on the list of non-cooperative jurisdictions for lacking in the enforcement of economic substance requirements. The Marshall Islands has stated that it is of the opinion that it has met its commitments to the Council’s code of conduct group thus far, and the Marshall

35

Table of Contents

Islands has confirmed it will continue to work closely with the EU and the Council’s code of conduct group to address any technical concerns of the EU member states. EU member states have agreed upon a set of measures, which they can choose to apply against the listed countries, including increased monitoring and audits, withholding taxes, and non-deductibility of costs, and although we are not currently aware of any such measures being adopted, they can be adopted by one or more EU members states in the future. The European Commission has stated it will continue to support member states’ efforts to develop a more coordinated approach to sanctions for the listed countries. EU legislation prohibits certain EU funds from being channeled or transited through entities in non-cooperative jurisdictions.

We are a Marshall Islands limited partnership and KNOT UK is a Marshall Islands limited liability company. The Marshall Islands has enacted economic substance regulations with which we are obligated to comply. The Marshall Islands economic substance regulations require certain entities that are not otherwise tax resident outside of the Marshall Islands that carry out particular activities to comply with an economic substance test whereby the entity must show that it (i) is directed and managed in the Marshall Islands in relation to that relevant activity, (ii) carries out core income-generating activity in relation to that relevant activity in the Marshall Islands (although it is being understood and acknowledged by the regulators that income-generated activities for shipping companies will generally occur in international waters) and (iii) having regard to the level of relevant activity carried out in the Marshall Islands has (a) an adequate amount of expenditures in the Marshall Islands, (b) adequate physical presence in the Marshall Islands and (c) an adequate number of qualified employees in the Marshall Islands. Based on our current business activities, we believe that we and KNOT UK are not required to comply with this economic substance test.

In addition, certain jurisdictions have enacted or may enact economic substance laws and regulations with which we may be obligated to comply. If we fail to comply with our obligations under any such laws and regulations, including the Marshall Islands regulations, we could be subject to financial penalties and disclosure of information to foreign tax officials, or could be struck from the register of companies. Any of the foregoing could be disruptive to our business and could have a material adverse effect on our business, financial conditions and operating results.

We do not know how long the Marshall Islands will remain on the non-cooperative list; what actions the Marshall Islands may take, if any, to remove itself from the list; how quickly the EU would react to any changes in legislation of the Marshall Islands; or how EU banks or other counterparties will react while we or KNOT UK remain as entities organized and existing under the laws of the Marshall Islands. The effect of the EU list of non-cooperative jurisdictions, and any noncompliance by us with legislation adopted by the Marshall Islands to achieve removal from the list, could have a material adverse effect on our business, financial conditions and operating results.

Because we are organized under the laws of the Marshall Islands, it may be difficult to serve us with legal process or enforce judgments against us, our directors or our management.

We are organized under the laws of the Marshall Islands, and substantially all of our assets are located outside of the United States. In addition, our general partner is a Marshall Islands limited liability company, and our directors and officers generally are or will be non-residents of the United States, and all or a substantial portion of the assets of these non-residents are located outside the United States. As a result, it may be difficult or impossible for our unitholders to bring an action against us or against these individuals in the United States if our unitholders believe that their rights have been infringed under securities laws or otherwise. Even if our unitholders are successful in bringing an action of this kind, the laws of the Marshall Islands and of other jurisdictions may prevent or restrict our unitholders from enforcing a judgment against our assets or the assets of our general partner or our directors or officers.

36

Table of Contents

Our partnership agreement designates the Court of Chancery of the State of Delaware as the exclusive forum for certain types of actions and proceedings that may be initiated by our unitholders unless otherwise provided for under the laws of the Marshall Islands. This limits our unitholders’ ability to choose the judicial forum for disputes with us or our directors, officers or other employees.

Our partnership agreement provides that, with certain limited exceptions, the Court of Chancery of the State of Delaware is the exclusive forum for any claims, suits, actions or proceedings (1) arising out of or relating in any way to our partnership agreement (including any claims, suits or actions to interpret, apply or enforce the provisions of our partnership agreement or the duties, obligations or liabilities among limited partners or of limited partners to us, or the rights or powers of, or restrictions on, our limited partners or us); (2) brought in a derivative manner on our behalf; (3) asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of us or our general partner, or owed by our general partner, to us or our limited partners; (4) asserting a claim arising pursuant to any provision of the Marshall Islands Act; and (5) asserting a claim governed by the internal affairs doctrine. This exclusive forum provision does not apply to actions arising under the U.S. Securities Act of 1933, as amended (the “Securities Act”) or the U.S. Securities and Exchange Act of 1934, as amended (the “Exchange Act”). Any person or entity purchasing or otherwise acquiring any interest in our units is deemed to have received notice of and consented to the foregoing provisions.

Although we believe these provisions will benefit us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against our directors, officers, employees and agents. The enforceability of similar forum selection provisions in other companies’ certificates of incorporation or similar governing documents have been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could find that the forum selection provision contained in our partnership agreement is inapplicable or unenforceable in such action or actions. Limited partners will not be deemed, by operation of the forum selection provision alone, to have waived claims arising under the federal securities laws and the rules and regulations thereunder. If a court were to find this choice of forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our financial position, results of operations and ability to make cash distributions to our unitholders.

Tax Risks

In addition to the following risk factors, you should read “Item 4. Information on the Partnership—Business Overview—Taxation of the Partnership” and “Item 10. Additional Information—Taxation” for a more complete discussion of the expected material U.S. federal and non-U.S. income tax considerations relating to us and the ownership and disposition of our common units.

We are subject to taxes, which reduces our cash available for distribution to our unitholders.

We and our subsidiaries may be subject to tax in the jurisdictions in which we are organized or operate, reducing the amount of cash available for distribution. In computing our tax obligations in these jurisdictions, we are required to take various tax accounting and reporting positions on matters that are not entirely free from doubt and for which we have not received rulings from the governing authorities. We cannot assure you that, upon review of these positions, the applicable authorities will agree with our positions. A successful challenge by a tax authority could result in additional tax imposed on us or our subsidiaries, as well as possibly interest and penalties, further reducing the cash available for distribution. In addition, changes in our operations or ownership could result in additional tax being imposed on us or our subsidiaries in jurisdictions in which operations are conducted.

A change in tax laws in any country in which we operate could adversely affect us.

Tax laws and regulations are highly complex and subject to interpretation. Consequently, we and our subsidiaries are subject to changing tax laws, treaties and regulations in and between countries in which we operate. Our income tax expense is based on our interpretation of the tax laws in effect at the time the expense was incurred. A change in tax laws, treaties or regulations, or in the interpretation thereof, could result in a materially higher tax expense or a higher effective tax rate on our earnings. Such changes may include measures enacted in response to the ongoing initiatives in relation to fiscal legislation at an international level, such as the Action Plan on Base Erosion and Profit Shifting of the Organization for Economic Co-operation and Development.

U.S. tax authorities could treat us as a “passive foreign investment company,” which would have adverse U.S. federal income tax consequences to U.S. unitholders.

A non-U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a “passive foreign investment company” (a “PFIC”) for U.S. federal income tax purposes if at least 75% of its gross income for any taxable year consists of “passive income” or at least 50% of the average value of its assets produce, or are held for the production of, “passive income.” For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property, and rents and royalties other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business. For purposes of these tests, income derived from the performance of services does not constitute “passive income.” U.S. unitholders of a PFIC are subject to a disadvantageous U.S. federal income tax regime with respect to the income derived by the PFIC, the distributions they receive from the PFIC, and the gain, if any, they derive from the sale or other disposition of their interests in the PFIC, unless the U.S. unitholders make certain elections.

Based on our current and projected method of operation, we believe that we were not a PFIC for any prior taxable year, and we expect that we will not be treated as a PFIC for the current or any future taxable year. We believe that more than 25% of our gross income for each taxable year was or will be non-passive income, and more than 50% of the average value of our assets for each such year was or will be held for the production of non-passive income. This belief is based on certain valuations and projections regarding our income and assets, and its validity is based on the accuracy of such valuations and projections. While we believe these valuations and projections to be accurate, the shipping market is volatile, and no assurance can be given that they will continue to be accurate at any time in the future.

Moreover, there are legal uncertainties involved in determining whether the income derived from time-chartering activities constitutes rental income or income derived from the performance of services. In Tidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), the United States Court of Appeals for the Fifth Circuit (the “Fifth Circuit”) held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a provision of the Internal Revenue Code of 1986, as amended (the “Code”), relating to foreign sales corporations. In that case, the Fifth Circuit did not address the definition of passive income or the PFIC rules; however, the reasoning of the case could have implications as to how the income from a time charter would be classified under such rules. If the reasoning of this case were extended to the PFIC context, the gross income we derive or are deemed to derive from our time-chartering activities may be treated as rental income, and we would likely be treated as a PFIC. In published guidance, the Internal Revenue Service (the “IRS”) stated that it disagreed with the holding in Tidewater and specified that time charters similar to those at issue in the case should be treated as service contracts. We have not sought, and we do not expect to seek, an IRS ruling on the treatment of income generated from our time-chartering activities. As a result, the IRS or a court could disagree with our position. No assurance can be given that this result will not occur. In addition, although we intend to conduct our affairs in a manner to avoid, to the extent possible, being classified as a PFIC with respect to any taxable year, we cannot assure you that the nature of our operations will not change in the future, or that we will not be a PFIC in the future. If the IRS were to find that we are or have been a PFIC for any taxable year (and regardless of whether we remain a PFIC for any subsequent taxable year), our U.S. unitholders would face adverse U.S. federal income tax consequences. Please read “Item 10. Additional Information—Taxation—U.S. Federal Income Taxation of U.S. Holders—PFIC Status and Significant Tax Consequences” for a more detailed discussion of the U.S. federal income tax consequences to U.S. unitholders if we are treated as a PFIC.

We may have to pay tax on U.S. source income, which would reduce our cash flow.

Under the Code, U.S. source gross transportation income generally is subject to a 4% U.S. federal income tax without allowance for deduction of expenses, unless an exemption from tax applies under a tax treaty or Section 883 of the Code and the Treasury Regulations promulgated thereunder. U.S. source gross transportation income consists of 50% of the gross shipping income that is attributable to transportation that begins or ends, but that does not both begin and end, in the United States.

We expect that our vessel-owning subsidiaries will qualify for an exemption from U.S. tax on any U.S. source gross transportation income under the Convention Between the United States of America and the Kingdom of Norway with Respect to Taxes on Income and Property (the “U.S.-Norway Tax Treaty”), and we intend to take this position for U.S. federal income tax purposes. However, if we acquire interests in vessel-owning subsidiaries in the future that are not Norwegian residents for purposes of the U.S.-Norway Tax Treaty, U.S. source gross transportation income earned by those subsidiaries would generally be subject to a 4% U.S. federal income tax unless the exemption under Section 883 of the Code applied. In general, the Section 883 exemption provides that if a non-U.S. corporation satisfies the requirements of Section 883 of the Code and the Treasury Regulations thereunder, it will not be subject to the 4% U.S. federal income tax referenced above on its U.S. source gross transportation income. The Section 883 exemption does not apply to income attributable to transportation that begins and ends in the United States.

The vessels in our fleet do not currently engage in transportation that begins and ends in the United States, and we do not expect that our subsidiaries will in the future earn income from such transportation. If, notwithstanding this expectation, our subsidiaries earn income in the future from transportation that begins and ends in the United States, that income may not be exempt from U.S. federal income tax under Section 883 of the Code and may not be exempt from U.S. federal income tax under the U.S.-Norway Tax Treaty and therefore may be subject to net income tax in the United States (currently at a 21% rate, plus branch profits tax at a rate of 30% (unless reduced or eliminated under an income tax treaty)).

The imposition of U.S. federal income tax on our income could have a negative effect on our business and would result in decreased earnings available for distribution to our unitholders.

Our unitholders may be subject to income tax in one or more non-U.S. jurisdictions as a result of owning our common units if, under the laws of any such jurisdiction, we are considered to be carrying on business there. Such laws may require our unitholders to file a tax return with, and pay taxes to, those jurisdictions.

We conduct our affairs and cause each of our subsidiaries to operate its business in a manner that minimizes income taxes imposed upon us and our subsidiaries. Furthermore, we conduct our affairs and cause each of our subsidiaries to operate its business in a manner that minimizes the risk that unitholders may be treated as having a permanent establishment or taxable presence in a jurisdiction where we or our subsidiaries conduct activities simply by virtue of their ownership of our common units. However, because we are organized as a partnership, there is a risk in some jurisdictions, including Norway and the United Kingdom, that our activities or the activities of our subsidiaries may rise to the level of a taxable presence that is attributed to our unitholders for tax purposes. We obtained confirmation from the United Kingdom HM Revenue & Customs that unitholders should not be treated as trading in the United Kingdom merely by virtue of their ownership of our common units. If our unitholders are attributed such a taxable presence in a jurisdiction, our unitholders may be required to file a tax return with, and to pay tax in, that jurisdiction based on our unitholders’ allocable share of any identifiable taxable income. In addition, we may be required to obtain information from our unitholders in the event a tax authority (including in the United Kingdom) requires such information to submit a tax return. We may be required to reduce distributions to our unitholders on account of any tax withholding obligations imposed upon us by that jurisdiction in respect of such allocation to our unitholders. The United States generally will not allow a tax credit for any foreign income taxes that our unitholders directly or indirectly incur by virtue of an investment in us.

B. Business Overview

General

We were formed to own and operate shuttle tankers, initially and wherever possible, under long-term charters. Our primary business objective is to generate stable cash flows and provide a sustainable quarterly distribution per unit to our unitholders. Where possible, our further objective is to grow our business through accretive acquisitions of shuttle tankers and by chartering those vessels pursuant to profitable charters with high quality customers. The vessels in our current fleet are chartered to Equinor, Transpetro, Repsol, Shell, Galp, Altera, China Offshore Oil (Singapore), International Pte. Ltd., TotalEnergies and KNOT, and our charters have an average remaining term excluding options of 1.9 years as of December 31, 2022 and 2.3 years excluding options but including contracts and extensions signed after December 31, 2022 but before March 30, 2023.

We intend to leverage the relationships, expertise and reputation of KNOT, a leading independent owner and operator of shuttle tankers, to pursue potential growth opportunities and to attract and retain high-quality, creditworthy customers. As of March 30, 2023, KNOT and our general partner owned our general partner interest, all our Class B Units and 28.6% of our common units. KNOT intends to utilize us as its primary growth vehicle to pursue the acquisition of long-term, stable cash-flow-generating shuttle tankers.

Business Strategies

Our primary business objective is to generate stable cash flows and provide a sustainable quarterly distribution per unit to our unitholders by executing the following strategies:

We can provide no assurance, however, that we will be able to implement our business strategies described above. For further discussion of the risks that we face, please read “Item 3. Key Information—Risk Factors.”

Shuttle Tanker Market

A shuttle tanker is a specialized vessel designed to transport crude oil and condensates from offshore oil field installations to onshore terminals and refineries. Shuttle tankers are equipped with sophisticated loading systems and dynamic positioning systems that allow the vessels to load cargo safely and reliably from oil field installations, even in harsh weather conditions.

Shuttle tankers are often described as “floating pipelines,” because these vessels typically shuttle oil from offshore installations to onshore facilities in much the same way a pipeline would transport oil along the ocean floor. Shuttle tankers are typically purpose-built but can be converted from existing conventional oil tankers after a substantial upgrade and investment in equipment.

The advantages of shuttle tankers as compared to pipelines include:

Shuttle tankers primarily differ from conventional oil tankers based on two significant features. First, shuttle tankers are fitted with dynamic position-keeping equipment enabling them to remain in a position without the assistance of tugs or mooring to installations. Second, shuttle tankers are equipped with bow-loading equipment and, in some cases, also fitted with equipment for submerged turret loading. Conventional oil tankers load from an offshore field installation usually through a taut hawser (mooring line onboard the discharging unit) operation and/or with tug assistance. In certain cases, dedicated shuttle tanker newbuilds are required to service the specific requirements of oil fields and installations.

Customers

For the year ended December 31, 2022, Transpetro, Eni, Repsol, Galp, and Shell accounted for approximately 17%, 14%, 14%, 6% and 5%, respectively, of our revenues. Equinor, Vår, TotalEnergi, PetroChina, China Offshore Oil (Singapore), International Pte. Ltd. Petrobras and KNOT accounted for our remaining revenues.

Charters

We generate revenues by charging customers for the hire of our vessels and for services related to the loading, transportation, discharge and storage of their crude oil using the vessels in our fleet. We mainly provide all of these services under time charters and bareboat charters, however, some of our vessels operated on spot voyages in 2022.

As of March 30, 2023, fifteen of our shuttle tankers are chartered under time charters and three of our shuttle tankers are chartered under bareboat charters.

A time charter is a contract for the use of a specified vessel for a fixed period of time at a specified daily rate. Under time charters, the shipowner is responsible for providing crewing and other vessel operating services, the cost of which is included in the daily rate, while the customer is responsible for substantially all of the voyage expenses. A bareboat charter is a contract for the use of a specified vessel for a fixed period of time at a specified daily or annual rate. Under bareboat charters, the shipowner is not responsible for providing crewing or other operational services, while the customer is responsible for all vessel operating expenses and voyage expenses. In addition, bareboat charters also provide that the shipowner is responsible for repairs or renewals occasioned by latent defects in the vessel existing at the time of delivery, provided such defects have manifested themselves within 18 months after delivery. However, under bareboat charters, the customer is responsible for ordinary repair and maintenance, including drydocking. A spot charter or single voyage charter is a contract whereby the charterer is entitled to use the vessel to perform transportation services between specific geographical locations, typically at a pre-agreed freight rate.

44

Table of Contents

Initial Term; Extensions

The initial term for a time charter or bareboat charter commences upon the vessel’s delivery to the customer. Our time charters often include options, exercisable by the customer, to extend the charter’s initial term. Under the time charters, the customer may also extend the term for periods in which the vessel is off-hire, as described below. Customers under each of our time charters and bareboat charters have rights to terminate the charter prior to expiration of the original or any extended term in specified circumstances (see also “—Termination” below).

Hire Rate

Hire rate refers to the basic payment from the customer for the use of the vessel. Under our time charters, the majority of hire rate is payable monthly in advance, in U.S. Dollars. The hire rate payable under our time charters is either a fixed amount for the firm period of the time charter with escalations to be made in case of option periods or increases annually based on a fixed percentage increase or fixed schedule, in order to enable us to offset expected increases in operating costs. Under our time charters, hire rate payments may be reduced if the vessel does not perform to certain of its specifications, such as if the average vessel speed falls below a guaranteed speed or the amount of fuel consumed to power the vessel under normal circumstances exceeds a guaranteed amount.

The hire rate payable under our bareboat charters is fixed and payable monthly in advance, in U.S. Dollars. The customer is also required to maintain minimum levels of insurance to protect the interests of the customer, the shipowner and mortgagees, if any.

The hire rate payable under spot charters is fixed in advance at a specified freight rate per ton, in U.S. Dollars. Under a spot charter agreement, voyage expenses are paid by the Partnership as owner of the vessel.

Off-hire

Under our time charters, when the vessel is off-hire, or not available for service, the customer generally is not required to pay the hire rate, and the shipowner is responsible for all costs. Prolonged off-hire may lead to a termination of the time charter. A vessel generally will be deemed off-hire if there is a loss of time due to, among other things:

Our bareboat charters do not contain provisions for off-hire.

Ship Management and Maintenance

Under our time charters, the shipowner is responsible for the technical management of the vessel and for maintaining the vessel, periodic drydocking, cleaning and painting and performing work required by regulations. KNOT Management and KNOT Management Denmark provide these services to our subsidiaries for all our vessels under time charters. Please read “Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions.” Under our bareboat charters, the shipowner is not responsible for providing crewing or other operational services and the customer is responsible for all vessel operating expenses and voyage expenses. However, as at December 31, 2022, Transpetro had elected to subcontract the technical operation and management of the Fortaleza Knutsen, the Recife Knutsen, the Dan Cisne and the Dan Sabia to an affiliate of KNOT.

Termination

Each of our time charters and bareboat charters terminates automatically if the applicable vessel is lost or missing. In addition, under certain circumstances, the customer may have an option to terminate the time charter if the vessel is requisitioned by any government for a period of time in excess of the time period specified in the time charter or if at any time the shipowner is in default under the time charter. Under the bareboat charters, the charter is deemed terminated as of the date of any compulsory acquisition of the vessel or requisition for title by any governmental or other competent authority. In addition, the shipowner is generally entitled to

45

Table of Contents

suspend performance (but with the continuing accrual to its benefit of hire rate payments and default interest) and terminate the charter if the customer defaults in its payment obligations. Under the time charters and bareboat charters, either party may also terminate the charter in the event of war in specified countries.

However, under the bareboat charters, in the event of war, hire shall continue to be paid in accordance with the charter until redelivery. In addition, under the bareboat charters, the shipowner has the right to terminate the charter if the customer (1) does not take immediate steps to have the necessary repairs done within a reasonable time or (2) does not arrange and keep certain insurance.

Competition

The shuttle tanker industry is capital intensive and operational expertise is critical, which create high barriers to entry. The shuttle tanker industry is viewed as an integral part of offshore oil production creating a market with few alternative suppliers and therefore a low risk of substitution. A company with a solid track record, knowledge of the market and an experienced, well-trained crew is preferred to a new entrant since the cost and impact of vessel downtime is significant for the customer. Furthermore, the systems in place for operational procedures, such as offshore loading and vetting, have significant value when negotiating contracts with new and existing customers.

According to Fearnresearch, as of March 1, 2023, there were 75 vessels in the global shuttle tanker fleet plus 6 newbuilds on order. Together KNOT and KNOP are the largest owners of shuttle tankers with 27 shuttle tankers plus 2 newbuilds on order. Altera Shuttle Tankers L.L.C. (formerly Teekay Offshore Partners L.P.) is the second largest owner in the shuttle tanker market with 20 shuttle tankers and no new vessels on order. American Eagle Tankers (AET) is the third largest owner of shuttle tankers with 17 vessels and no new vessels on order. Petrobras, which does not own vessels, employs a total of 22 shuttle tankers through long-term bareboat and time charters (and has agreements to charter 2 newbuilds on order). There are other shuttle tanker owners in the industry, but such owners have a limited fleet size and their vessels do not participate or compete in our markets.

Classification, Inspection and Maintenance

Every large, commercial seagoing vessel must be “classed” by a classification society. The classification society certifies that the vessel is “in class,” signifying that the vessel has been built and maintained in accordance with the rules of the classification society. In most cases, the classification society is authorized by the flag state to certify that the vessels also comply with applicable rules and regulations of the vessel’s country of registry and the international conventions of which that country is a member. In addition, where surveys are required by international conventions and corresponding laws and ordinances of a flag state, the classification society may undertake them on application or by official order, acting on behalf of the authorities concerned. The classification society also undertakes on request other surveys and checks that are required by regulations and requirements of the flag state. These surveys are subject to agreements made in each individual case and/or to the regulations of the country concerned. For maintenance of the class, regular and extraordinary surveys of hull, machinery, including the electrical plant, and any special equipment classed are required to be performed by the classification society as follows:

46

Table of Contents

All of the vessel’s areas subject to survey as defined by the classification society are required to be surveyed at least once per class period, unless shorter intervals between surveys are prescribed elsewhere. The period between two subsequent surveys of each area must not exceed five years.

A vessel’s underwater parts are required to be inspected every 24 to 36 months by the classification society. Drydocking of vessels is done, at the minimum, every 60 months until the vessel is 15 years old and every 30 months thereafter. If any defects are found, the classification surveyor will issue a condition of class that must be rectified by the shipowner.

Most insurance underwriters make it a condition for insurance coverage that a vessel be certified as “in class” by a classification society that is a member of the International Association of Classification Societies. All of our vessels have been awarded International Safety Management certification and are certified as being “in class” by DNV GL or ABS, the Norwegian and American classification societies, respectively. All new and secondhand vessels that we purchase must be certified prior to their delivery under the standard purchase contracts and memoranda of agreement. If the vessel is not certified on the date of closing, we will have no obligation to take delivery of the vessel.

KNOT, through certain of its subsidiaries, operates as our ship manager, and carries out inspections of the ships on a regular basis, both at sea and while the vessels are in port, as well as carrying out inspections and ship audits to verify conformity with managers’ reports. The results of these inspections result in a report containing recommendations for improvements to the overall condition of the vessel, maintenance, safety and crew welfare. Based in part on these evaluations, we create and implement a program of continual maintenance and improvement for our vessels and their systems.

Safety, Management of Ship Operations and Administration

Safety and environmental compliance is our top operational priority. Our vessels are operated in a manner intended to protect the safety and health of our employees, the general public and the environment. We actively manage the risks inherent in our business and are committed to eliminating incidents that threaten the safety and integrity of our vessels, such as groundings, fires, collisions and petroleum spills. We are also committed to reducing emissions, carbon intensity and waste generation. We have established key performance indicators to facilitate regular monitoring of our operational performance. We set targets on an annual basis to drive continuous improvement, and we review performance indicators monthly to determine if remedial action is necessary to reach our targets. KNOT’s shore staff performs a full range of technical, commercial and business development services for us. This staff also provides administrative support to our operations in finance, accounting and human resources.

KNOT, through certain of its subsidiaries, assists us and our operating subsidiaries in managing our ship operations. DNV GL, a Norwegian classification society, has approved KNOT’s safety management system, which has been implemented on all our ships, as complying with the IMO’s International Management Code for the Safe Operation of Ships and Pollution Prevention (the “ISM Code”), International Standards Organization (“ISO”) 9001 for Quality Assurance, ISO 14001 for Environment Management Systems and OHSAS 18001, for Occupational Health and Safety Management System. As part of KNOT’s ISM Code compliance, all the vessels’ safety management certificates are being maintained through ongoing internal audits performed by KNOT’s certified internal auditors and external audits performed by DNV GL or the respective flag state. Subject to satisfactory completion of these internal and external audits, certification is valid for five years.

KNOT provides, through certain of its subsidiaries, expertise in various functions critical to the operations of our operating subsidiaries. We believe this arrangement affords a safe, efficient and cost-effective operation. KNOT’s subsidiaries also provide to us access to human resources, financial and other administrative functions pursuant to technical management agreements. Please read “Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions—Technical Management Agreements.”

47

Table of Contents

Critical ship management functions that are provided by KNOT or its subsidiaries through various of its offices around the world include:

These functions are supported by onboard and onshore systems for maintenance, inventory, purchasing and budget management. In addition, KNOT’s day-to-day focus on cost control is applied to our operations. We believe that the adoption of common standards results in operational efficiencies, including with respect to crew training and vessel management, equipment operation and repair, and spare parts ordering.

Risk of Loss, Insurance and Risk Management

The operation of any vessel, including shuttle tankers, has inherent risks. These risks include mechanical failure, personal injury, collision, property loss, vessel or cargo loss or damage and business interruption due to political circumstances in foreign countries or hostilities. In addition, there is always an inherent possibility of marine disaster, including explosion, spills and other environmental mishaps, and the liabilities arising from owning and operating vessels in international trade. We believe that our present insurance coverage is adequate to protect us against the accident-related risks involved in the conduct of our business and that we maintain appropriate levels of environmental damage and pollution insurance coverage consistent with standard industry practice. However, not all risks can be insured, and there can be no guarantee that any specific claim will be paid, or that we will always be able to obtain adequate insurance coverage at reasonable rates.

We have obtained hull and machinery insurance on all our vessels to insure against marine and war risks, which include the risks of damage to our vessels, salvage or towing costs, and also insure against actual or constructive total loss of any of our vessels. However, our insurance policies contain deductible amounts for which we are responsible. We have also arranged additional total loss coverage for each vessel. This coverage, which is called hull interest and freight interest coverage, provides us additional coverage in the event of the total loss or the constructive total loss of a vessel.

We have also obtained loss of hire insurance to protect us against loss of income in the event one of our vessels cannot be employed due to damage that is covered under the terms of our hull and machinery insurance. Under our loss of hire policies, our insurer will pay us the hire rate agreed in respect of each vessel for each day, in excess of a certain number of deductible days, for the time that the vessel is out of service as a result of damage, for a maximum of 180 days. The number of deductible days for the vessels in our fleet is 14 days per vessel.

All of our hull and machinery, hull interest and freight interest and loss of hire insurance policies are written on the Norwegian Marine Insurance Plan (“NMIP”), which through the hull and maintenance coverage also offers comprehensive collision liability coverage of up to the insured hull and maintenance value of the vessel. NMIP is based on an “all risk principle” and offers what is considered to be the most comprehensive insurance obtainable in any of the world’s marine markets today. The agreed deductible on each vessel averages $150,000 for the shuttle tankers in our fleet.

Protection and indemnity insurance, which covers our third-party legal liabilities in connection with our shipping activities, is provided by a P&I club. This includes third-party liability and other expenses related to the injury or death of crew members, passengers and other third-party persons, loss or damage to cargo, claims arising from collisions with other vessels or from contact with jetties or wharves and other damage to other third-party property, including pollution arising from oil or other substances, and other related costs, including wreck removal. Subject to the capping discussed below, our coverage, except for pollution, is unlimited.

Our current protection and indemnity insurance coverage for pollution is $1 billion per vessel per incident. The 13 P&I clubs that comprise the International Group of Protection and Indemnity Clubs insure approximately 90% of the world’s commercial tonnage and have entered into a pooling agreement to reinsure each association’s liabilities. Each P&I club has capped its exposure in this pooling agreement so that the maximum claim covered by the pool and its reinsurance would be approximately $1 billion per accident or occurrence. We are a member of Norwegian P&I Club Skuld.

As a member of these P&I clubs, we are subject to a call for additional premiums based on the clubs’ claims record, as well as the claims record of all other members of the P&I clubs comprising the International Group. However, our P&I clubs have reinsured the risk of additional premium calls to limit our additional exposure. This reinsurance is subject to a cap, and there is the risk that the full amount of the additional call would not be covered by this reinsurance.

The insurers providing the covers for hull and machinery, hull interest and freight interest, protection and indemnity and loss of hire insurances have confirmed that they will consider the shuttle tankers as vessels for the purpose of providing insurance.

We use in our operations KNOT’s risk management program that includes, among other things, risk analysis tools, maintenance and assessment programs, a seafarers competence training program, seafarers workshops and membership in emergency response organizations. We benefit from KNOT’s commitment to safety and environmental protection as certain of its subsidiaries assist us in managing our vessel operations.

KNOT has achieved certification under the standards reflected in ISO 9001 for quality assurance, ISO 14001 for environment management systems and the ISM Code on a fully integrated basis.

Environmental and Other Regulation

General

Our business and the operation of our vessels are significantly affected by international conventions and national, state and local laws and regulations in the jurisdictions in which our vessels operate, as well as in the country or countries of their registration. Because these conventions, laws and regulations change frequently, we cannot predict the ultimate cost of compliance or their impact on the resale price or useful life of our vessels. While we believe that we are in substantial compliance with the current environmental laws and regulations that apply to our operations, there is no assurance that such compliance or compliance with amended or newly adopted laws and regulations can be maintained in the future. Additional conventions, laws, and regulations may be adopted that could limit our ability to do business or increase the cost of our doing business and that may materially adversely affect our operations. We are required by various governmental and quasi-governmental agencies to obtain permits, licenses and certificates with respect to our operations. Subject to the discussion below and to the fact that the kinds of permits, licenses and certificates required for the operations of the vessels we own depend on a number of factors, we believe that we will be able to continue to obtain all permits, licenses and certificates material to the conduct of our operations.

International Maritime Organization

The IMO is the United Nations’ agency responsible for developing measures to improve the safety and security of international shipping and to prevent marine pollution from ships. IMO regulations relating to pollution prevention for oil tankers have been adopted by many of the jurisdictions in which our tanker fleet operates. Under IMO regulations and subject to limited exceptions, a tanker must be of double-hull construction, a mid-deck design with double-side construction or another approved design ensuring the same level of protection against oil pollution. All of our tankers are of double-hull construction.

Many countries, but not the United States, have ratified and follow the liability regime adopted by the IMO and set out in the International Convention on Civil Liability for Oil Pollution Damage, 1969, as updated by the 1992 Protocol (the “CLC”). Under this

49

Table of Contents

convention, a vessel’s registered owner is strictly liable for pollution damage caused in the territorial waters of a contracting state by discharge of persistent oil (e.g. crude oil, fuel oil, heavy diesel oil or lubricating oil), subject to certain defenses. The right to limit liability to specified amounts that are periodically revised is forfeited under the CLC when the spill is caused by the owner’s actual fault or when the spill is caused by the owner’s intentional or reckless conduct. Vessels trading to contracting states must provide evidence of insurance covering the limited liability of the owner. In jurisdictions where the CLC has not been adopted, various legislative regimes or common law govern, and liability is imposed either on the basis of fault or in a manner similar to the CLC. IMO regulations also include SOLAS, including amendments to SOLAS implementing the International Security Code for Ports and Ships (the “ISPS”), the ISM Code and the International Convention on Load Lines of 1966. The IMO Marine Safety Committee has also published guidelines for vessels with dynamic positioning systems, which apply to shuttle tankers. SOLAS provides rules for the construction of, and equipment required for, commercial vessels and includes regulations for safe operation. Flag states that have ratified the CLC generally utilize the classification societies, which have incorporated SOLAS requirements into their class rules, to undertake surveys to confirm compliance.

SOLAS and other IMO regulations concerning safety, including those relating to treaties on training of shipboard personnel, lifesaving appliances, radio equipment and the global maritime distress and safety system, are applicable to our operations. Non-compliance with IMO regulations, including SOLAS, the ISM Code, and the ISPS, or the requirements for shuttle tankers under their flag regulations, may subject us to increased liability or penalties, may lead to decreases in available insurance coverage for affected vessels and may result in the denial of access to or detention in some ports. For example, the U.S. Coast Guard, the United Kingdom Maritime and Coastguard Agency and EU authorities have indicated that vessels not in compliance with the ISM Code will be prohibited from trading in U.S., the United Kingdom and EU ports.

The requirements contained in the ISM Code govern our operations. Among other requirements, the ISM Code requires vessel operators to obtain a safety management certification for each vessel they manage, evidencing the shipowner’s development and maintenance of an extensive safety management system. In 2017, the IMO’s Maritime Safety Committee (“MSC”) adopted Resolution MSC.428(98), Maritime Cyber Risk Management in Safety Management Systems, embracing guidelines on maritime cyber risk management approved by the MSC in 2017, affirming its view that the ISM Code requires mitigation of cyber risk as part of the safety management system, and effectively providing that that a vessel’s safety management system must account for cyber risks in compliance with the ISM Code no later than the vessel’s first annual compliance verification after January 1, 2021. Each of the existing vessels in our fleet is currently ISM Code-certified, and we expect to obtain safety management certificates for each newbuild upon delivery.

The International Labour Organization (the “ILO”) is a specialized agency of the United Nations with headquarters in Geneva, Switzerland. The ILO has adopted the Maritime Labor Convention 2006 (the “MLC 2006”) to improve safety onboard merchant vessels, which came into force of August 20, 2013. A Maritime Labor Certificate and a Declaration of Maritime Labor Compliance is required to ensure compliance with the MLC 2006 for all ships above 500 gross tons in international trade. Each of the existing vessels in our fleet is currently MLC 2006-certified, and we expect to obtain MLC 2006 certificates for each newbuild upon delivery.

The IMO has adopted the International Convention for the Prevention of Pollution from Ships (“MARPOL”), including Annex VI to MARPOL that sets limits on sulfur dioxide and nitrogen oxide emissions from ship exhausts and prohibits deliberate emissions of ozone depleting substances. Annex VI applies to all ships and, among other things, imposes a global cap on the sulfur content of fuel oil and allows for specialized areas to be established internationally with even more stringent controls on sulfur emissions. For vessels 400 gross tons and greater, platforms and drilling rigs, Annex VI imposes various survey and air pollution prevention certification requirements. Moreover, Annex VI regulations impose progressively stricter limitations on sulfur emissions from ships. As of January 2, 2015, these limitations required that fuels of vessels in covered Emission Control Areas (“ECAs”), including the North Sea ECA and the Baltic Sea ECA, contain no more than 0.1% sulfur. For non-ECA areas, the capped sulfur limitations decreased progressively until they reached the global limit of 0.5% applicable on and after January 1, 2020 (generally referred to as IMO 2020). In December 2022, the IMO’s Marine Environment Protection Committee adopted amendments to MARPOL Annex VI establishing a Mediterranean ECA for sulfur the enters into force on May 1, 2024 with a 12-month grace period. As a result, effective May 1, 2025, fuels of vessels in the Mediterranean ECA will need to meet the more stringent 0.1% sulfur limit. MARPOL Annex VI also establishes three tiers of stringent nitrogen oxide emissions standards for new marine engines, depending on their date of installation. All of our vessels are in compliance with these requirements.

In addition, there are several other regulatory requirements to use low sulfur fuel or restrict or regulate emissions from vessels. The EU Directive 33/2005 requiring the use of low sulfur fuel came into force on January 1, 2010. Under this legislation, vessels are

50

Table of Contents

required to burn fuel with sulfur content below 0.1% while berthed or anchored in an EU port. As of January 1, 2014, the California Air Resources Board’s Ocean-Going Vessel Fuel (“OGV”) Regulation requires vessels to burn fuel with 0.1% sulfur content or less within 24 nautical miles of California. Currently, the only grade of fuel meeting 0.1% sulfur content requirement is low sulfur marine gas oil. All of our vessels are able to comply with applicable low sulfur fuel requirements.

The IMO has negotiated international conventions that impose liability for oil pollution and other environmental harms in international waters and the territorial waters of the signatory to such conventions such as the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (the “BWM Convention”). The BWM Convention’s implementing regulations call for a phased introduction of mandatory ballast water exchange requirements (which began in 2009), to be replaced in time with a requirement for mandatory ballast water treatment. The BWM Convention entered into force on September 8, 2017. Brazil and Norway ratified the BWM Convention prior to its entry into force. The United Kingdom ratified the BMW Convention on May 26, 2022 and it entered into force in the United Kingdom on August 26, 2022. Although United States has not ratified the BWM Convention, it is implementing ballast water management requirements. As referenced below, the U.S. Coast Guard issued ballast water management rules on March 23, 2012. Under the requirements of the BWM Convention for units with ballast water capacity more than 5,000 cubic meters that were constructed in 2011 or before, ballast water management exchange or treatment were accepted until 2016. From 2016 (or not later than the first intermediate or renewal survey after 2016), only ballast water treatment will be accepted by the BWM Convention. We have installed ballast water treatment systems on all our vessels to comply with the requirements of the BWM Convention.

The International Convention on Civil Liability for Bunker Oil Pollution 2001 (the “Bunker Convention”) provides a liability, compensation and compulsory insurance system to protect and reimburse the victims of oil pollution damage in jurisdictional waters of ratifying states caused by discharges of bunker fuel. The Bunker Convention became effective in 2008 and imposes strict liability on shipowners for certain pollution damage. Registered owners of any seagoing vessel and seaborne craft over 1,000 gross tonnage, of any type whatsoever, and registered in a signatory state (a “State Party”), or entering or leaving a port in the territory of a State Party, will be required to maintain insurance that meets the requirements of the Bunker Convention and to obtain a certificate issued by a State Party attesting that such insurance is in force. The state-issued certificate must be carried onboard at all times. P&I clubs in the International Group issue the required Bunkers Convention “Blue Cards” to enable signatory states to issue certificates. All of our vessels have received “Blue Cards” from their P&I club and are in possession of a CLC State-issued certificate attesting that the required insurance coverage is in force.

The IMO continues to review and introduce new regulations. It is impossible to predict what additional regulations, if any, may be passed by the IMO and what effect, if any, such regulation may have on our operations.

European Union and United Kingdom Environmental Regulation of Vessels

In waters of the EU, our vessels are subject to regulation EU-level directives implemented by the various nations through laws and regulations adopting these requirements. These laws and regulations prescribe measures to prevent pollution, protect the environment, support maritime safety and set out civil and criminal penalties that are being progressively incorporated into domestic legislation. For instance, the EU has adopted legislation (EU Directive 2009/16/EC) that: bans from EU waters manifestly sub-standard vessels (defined as vessels that have been detained twice by EU port authorities, in the preceding two years); creates obligations on the part of EU member port states to inspect at least 24% of vessels using these ports annually; provides for increased surveillance of vessels posing a high risk to maritime safety or the marine environment; and provides the EU with greater authority and control over classification societies, including the ability to seek to suspend or revoke the authority of negligent societies. If deficiencies are found that are clearly hazardous to safety, health or the environment, the state is required to detain the vessel until the deficiencies are addressed. Member states are also required to implement a system of penalties for breaches of these standards. EU Directive 2009/16/EC introduced a harmonized and coordinated regime for port state control inspections and an on-line register to make public both the poorly performing shipping companies (who will attract more intensive and coordinated inspections) and those with good records. Like the IMO, the EU adopted regulations that phased out single-hull tankers. All of our tankers are double-hulled.

Several regulatory requirements to use low sulfur fuel are in force. See discussion of “low sulfur fuel” regulations above.

The EU is currently considering other proposals to further regulate vessel operations. We cannot predict what additional legislation or regulations, if any, may be promulgated by the EU or any other country or authority. The trend, however, is towards increasing regulation and our expectation is that requirements will become more extensive and more stringent over time.

Although the EU regulations no longer directly applies in the United Kingdom as a consequence of Brexit, the “level playing field” provisions in the United Kingdom/EU Trade and Cooperation Agreement (“TCA”) cover requires “non regression” in the level of environmental protection by the United Kingdom from the harmonized standards that were in effect in the EU on December 31, 2020. This means that the United Kingdom should not attempt to undo these standards, but under the TCA harmonization of standards is not required on a going forward basis. The TCA also includes a commitment for the EU and the United Kingdom to cooperate on trade-related aspects of climate change and to work with the IMO to achieve greenhouse gas emission reductions and promote low carbon technologies and sustainable transport. The United Kingdom has taken measures to put environmental regulations in place that would affect the shipping industry. In July 2019, the Department of Transport and the Maritime and Coast Guard Agency published Maritime 2050, a plan for the transition to zero emissions from shipping by 2050. On September 30, 2021, the Department of Transport adopted regulations amending the Merchant Shipping (Prevention of Air Pollution from Ships) Regulations 2008 to implement air quality measures to control sulfur and nitrogen oxide (SOx and NOx) emissions from ships, including setting the maximum sulfur content of marine fuels used by ships at 0.5% and applying stricter NOx Tier III limit for new ships operating in the North Sea and English Channel. On February 7, 2022, the United Kingdom Department for Transport issued a call for feedback on the priorities to be addressed in its development of a long-term low carbon fuels strategy for the transport sector and is considering responses received in the drafting of a low carbon fuels strategy.

If more stringent requirements are put in effect in the future in the EU or the United Kingdom, they may require, individually or in the aggregate, significant expenditures and could increase our operating costs, potentially affecting financial performance.

North Sea Environmental Regulation of Vessels

Our shuttle tankers currently operate in the North Sea and Brazil.

In addition to the regulations imposed by the IMO those countries having jurisdiction over North Sea areas impose further regulatory requirements on operations in those areas, including Maritime and Coastguard Agency regulations in the United Kingdom and Norwegian Maritime Directorate regulations in Norway. These regulatory requirements, together with additional requirements imposed by operators in North Sea oil fields, require that we make further expenditures for sophisticated equipment, reporting and redundancy systems on the shuttle tankers and for the training of seagoing staff. Additional regulations and requirements may be adopted or imposed that could limit our ability to do business or further increase the cost of doing business in the North Sea.

In Norway, the Norwegian Pollution Control Authority requires the installation of volatile organic compound emissions (“VOC”) control equipment, on most shuttle tankers serving the Norwegian continental shelf. The license holders of the oil field are responsible for the costs to ensure that shuttle tankers operating in the field are using appropriate VOC control equipment. In recent contracts, the charterers have requested owners to install such equipment against an increase in the hire rate. We have installed the VOC control equipment required to operate on the Norwegian continental shelf on each of the Fortaleza Knutsen, the Recife Knutsen, the Windsor Knutsen, the Hilda Knutsen, the Torill Knutsen and the Ingrid Knutsen. We have installed an advanced VOC recovery system on the Bodil Knutsen.

Brazilian Environmental Regulation of Vessels

In Brazil, the field operator and in most cases Petrobras where it is involved are required to establish internal procedures to manage pollution risks, which must be approved by the competent environmental authority. Brazilian environmental law includes international treaties and conventions to which Brazil is a party, including MARPOL and the CLC, as well as federal, state and local laws, regulations and permit requirements related to the protection of health and the environment. The petroleum industry in Brazil is subject to extensive regulations by several governmental agencies, including the National Agency of Petroleum, the Brazilian Navy and the Brazilian Institute of the Environment and Renewable Natural Resources. Legal obligations also include immediately notifying the competent authorities about any incident occurring in our vessels that may cause pollution in waters under the national jurisdiction of Brazil, in addition to the adoption of other required response actions. Failure to comply may subject us to administrative, criminal and civil liability, with strict and joint liability in civil cases. In Brazil, civil liability for environmental pollution aims for the complete recovery of the damage caused to the ecosystem and affected third parties, regardless of the cost involved.

United States Environmental Regulation of Vessels

In the United States, federal and state laws and regulations that require vessel owners and operators to obtain and maintain specified permits or governmental approvals; control the discharge of materials into the environment; remove and cleanup materials that may harm the environment; and otherwise comply with regulations intended to protect the environment. Vessel operations are subject to the jurisdiction of the U.S. Coast Guard, the National Transportation Safety Board, the U.S. Customs and Border Protection, the Department of Interior, the Bureau of Ocean Energy Management, and the Bureau of Safety and Environmental Enforcement, as well as classification societies such as the American Bureau of Shipping. The United States has enacted an extensive regulatory and liability regime for the protection and cleanup of the environment from oil spills, including discharges of oil cargoes, bunker fuels or lubricants, primarily through the Oil Pollution Act of 1990 (“OPA 90”) and the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”).

OPA 90 and CERCLA. CERCLA applies to the discharge of “hazardous substances” rather than “oil” and imposes strict joint and several liability upon the owners, operators or bareboat charterers of vessels for cleanup costs and damages arising from discharges of hazardous substances. We believe that petroleum products should not be considered hazardous substances under CERCLA, but additives to oil or lubricants used on vessels might fall within its scope.

OPA 90 affects all owners, bareboat charterers and operators whose vessels trade to the United States or its territories or possessions or whose vessels operate in U.S. waters, which include the U.S. territorial sea and 200-mile exclusive economic zone around the United States.

Under OPA 90, vessel owners, operators and bareboat charterers are “responsible parties” and are jointly, severally and strictly liable (unless the oil spill results solely from the act or omission of a third party, an act of God or an act of war and the responsible party reports the incident and reasonably cooperates with the appropriate authorities) for all containment and cleanup costs and other damages arising from discharges or threatened discharges of oil from their vessels. These other damages are defined broadly to include:

OPA 90 limits the liability of responsible parties in an amount it periodically updates. The liability limits do not apply if the incident was proximately caused by violation of applicable U.S. federal safety, construction or operating regulations, including IMO conventions to which the United States is a signatory, or by the responsible party’s gross negligence or willful misconduct, or if the responsible party fails or refuses to report the incident or to cooperate and assist in connection with the oil removal activities. Liability under CERCLA is also subject to limits unless the incident is caused by gross negligence, willful misconduct or a violation of certain regulations. We currently maintain for each of our vessel’s pollution liability coverage in the maximum coverage amount of $1 billion per incident. A catastrophic spill could exceed the coverage available, which could harm our business, financial condition and results of operations.

Under OPA 90, with limited exceptions, all newly built or converted tankers delivered after January 1, 1994 and operating in U.S. waters must be double-hulled. All of our tankers are double-hulled. OPA 90 also requires owners and operators of vessels to establish and maintain with the U.S. Coast Guard evidence of financial responsibility in an amount at least equal to the relevant limitation amount for such vessels under the statute. The U.S. Coast Guard has implemented regulations requiring that an owner or operator of a fleet of vessels must demonstrate evidence of financial responsibility in an amount sufficient to cover the vessel in the fleet having the

53

Table of Contents

greatest maximum limited liability under OPA 90 and CERCLA. Evidence of financial responsibility may be demonstrated by insurance, surety bond, self-insurance, guaranty or an alternate method subject to approval by the U.S. Coast Guard. Under the self-insurance provisions, the shipowner or operator must have a net worth and working capital, measured in assets located in the United States against liabilities located anywhere in the world, that exceeds the applicable amount of financial responsibility. We have complied with the U.S. Coast Guard regulations by using self-insurance for certain vessels and obtaining financial guaranties from a third party for the remaining vessels. If vessels in our fleet trade to the United States in the future, we expect to provide guaranties through self-insurance or obtain guaranties from third-party insurers.

OPA 90 and CERCLA permit individual U.S. states to impose their own liability regimes with regard to oil or hazardous substance pollution incidents occurring within their boundaries, and some states have enacted legislation providing for unlimited strict liability for spills. Several coastal states, such as California, Washington and Alaska require state-specific evidence of financial responsibility and vessel response plans. We intend to comply with all applicable regulations in the ports where our vessels call.

Owners or operators of vessels, including tankers operating in U.S. waters are required to file vessel response plans with the U.S. Coast Guard, and their tankers are required to operate in compliance with their U.S. Coast Guard approved plans. Such response plans must, among other things:

In addition, we conduct regular oil spill response drills in accordance with the guidelines set out in OPA 90. The U.S. Coast Guard has announced it intends to propose similar regulations requiring certain vessels to prepare response plans for the release of hazardous substances. OPA 90 and CERCLA do not preclude claimants from seeking damages resulting from the discharge of oil and hazardous substances under other applicable law, including maritime tort law. The application of this doctrine varies by jurisdiction.

Clean Water Act. The United States Clean Water Act (“CWA”) prohibits the discharge of oil or hazardous substances in United States navigable waters unless authorized by a permit or exemption, and imposes strict liability in the form of penalties for unauthorized discharges. The CWA also imposes substantial liability for the costs of removal, remediation and damages and complements the remedies available under OPA 90 and CERCLA. The U.S. Environmental Protection Agency (the “EPA”) has enacted rules governing the regulation of ballast water discharges and other discharges incidental to the normal operation of vessels within U.S. waters. The EPA authorized these incidental discharges pursuant to a permit the EPA designated as the Vessel General Permit for Discharges Incidental to the Normal Operation of Vessels (the “VGP”), which incorporated the current U.S. Coast Guard requirements for ballast water management as well as supplemental ballast water requirements, and includes limits applicable to 26 specific discharge streams, such as deck runoff, bilge water and gray water.

The EPA updated the VGP in 2013 to incorporate numeric effluent limits for ballast water expressed as the maximum concentration of living organisms in ballast water, as opposed to the prior non-numeric requirements. These requirements correspond with the IMO’s requirements under the BWM Convention, as discussed above. The permit also contains maximum discharge limitations for biocides and residuals. The numeric effluent limits took effect under a staggered implementation schedule and do not apply to all vessels. Vessels with deferred deadlines for meeting the numeric standards are required to meet Best Management Practices, which are substantially similar to the requirements under the previous VGP.

The VGP includes a tiered requirement for obtaining coverage based on the size of the vessel and the amount of ballast water carried. Vessels that are 300 gross tons or larger and have the capacity to carry more than eight cubic meters of ballast water must submit notices of intent (“NOIs”) to receive permit coverage between six and nine months after the permit’s issuance date. Vessels that do not need to submit NOIs are automatically authorized under the permit. In December 2018, the Vessel Incidental Discharge Act (“VIDA”) was signed into law and restructured the EPA and the U.S. Coast Guard programs for regulating incidental discharges from vessels. Rather than requiring CWA permits, the discharges will be regulated under a new CWA Section 312(p) establishing Uniform National Standards for Discharges Incidental to Normal Operation of Vessels. Under VIDA, VGP provisions and existing U.S. Coast Guard regulations will be phased out over a period of approximately four years and replaced with National Standards of

54

Table of Contents

Performance (“NSPs”) to be developed by EPA and implemented and enforced by the U.S. Coast Guard. VIDA requires EPA to develop NSPs for approximately 30 discharges by December 2020. The discharges to be covered are similar to those in 2013 VGP and the NSPs are generally required to be at least as stringent as the requirements of the 2013 VGP. On October 26, 2020, EPA issued proposed regulations to establish NSPs, including general discharge standards of performance, covering general operation and maintenance, biofouling management, and oil management, and specific discharge standards applicable to specified pieces of equipment and systems. Final regulations are expected in 2023. The scheduled expiration date of the 2013 VGP was December 18, 2018, but under VIDA the provisions of the VGP will remain in place until the new EPA NSPs and the corresponding U.S. Coast Guard implementation, compliance and enforcement regulations are in place. VIDA requires the corresponding U.S. Coast Guard regulations to be developed within two years following the adoption of the EPA NSPs.

In addition to the requirements in the VGP (to be replaced by the NSPs established under VIDA), vessel owners and operators must meet 25 sets of state-specific requirements under the CWA’s § 401 certification process. Because the CWA § 401 process allows tribes and states to impose their own requirements for vessels operating within their waters, vessels operating in multiple jurisdictions could face potentially conflicting conditions specific to each jurisdiction that they travel through.

While we do not believe that the costs associated with complying with the existing VGP permits and the NSPs that will be promulgated, including meeting related treatment requirements, will be material, it is difficult to predict the overall impact of CWA requirements on our business at this stage. In addition, state-specific requirements under the CWA’s § 401 and any similar restrictions enacted in the future could increase our costs of operating in the relevant waters.

National Invasive Species Act (“NISA”). In March 2012, the U.S. Coast Guard issued a final rule establishing standards for the allowable concentration of living organisms in ballast water discharged in U.S. waters and requiring the phase-in of U.S. Coast Guard approved ballast water management systems. The rule went into effect in June 2012 and set ballast water discharge standards for vessels calling on U.S. ports and intending to discharge ballast water equivalent to those set in IMO’s BWM Convention. The final rule requires that ballast water discharge have no more than ten living organisms per milliliter for organisms between ten and 50 micrometers in size. For organisms larger than 50 micrometers, the discharge can have no more than ten living organisms per cubic meter of discharge. New ships constructed on or after December 1, 2013 were required to comply with these ballast water treatment standards, with existing ships required to comply by their first drydock after January 1, 2014 or January 1, 2016, depending on size.

Clean Air Act. The United States Clean Air Act requires the EPA to promulgate standards applicable to emissions of volatile organic compounds and other air contaminants. Our vessels are subject to vapor control and recovery requirements for certain cargoes in regulated port areas and emission standards for so-called “Category 3” marine diesel engines operating in U.S. waters. The marine diesel engine emission standards are equivalent to those adopted set forth in Annex VI to MARPOL. Compliance with these standards may cause us to incur costs to install control equipment on our vessels in the future.

Trends in Environmental Regulation in the United States. Numerous governmental agencies issue regulations to implement and enforce the laws of the applicable jurisdiction, which often involve lengthy permitting procedures, impose difficult and costly compliance measures, particularly in ecologically sensitive areas, and subject operators to substantial administrative, civil and criminal penalties or may result in injunctive relief for failure to comply. Some of these laws contain criminal sanctions in addition to civil penalties. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent and costly compliance or limit contract drilling opportunities, including changes in response to a serious marine incident that results in significant oil pollution or otherwise causes significant adverse environmental impact, such as the April 2010 Macondo well blowout incident, could adversely affect our financial results. Although significant capital expenditures may be required to comply with these governmental laws and regulations, such compliance has not materially adversely affected our earnings or competitive position. We believe that we are currently in compliance in all material respects with the environmental regulations to which we are subject.

We may also be affected by or subject to permitting and other requirements under a variety of other environmental laws not discussed above, such as the Endangered Species Act, Marine Mammal Protection Act and National Environmental Policy Act.

Greenhouse Gas Regulation

In February 2005, the Kyoto Protocol to the United Nations Framework Convention on Climate Change (the “Kyoto Protocol”) entered into force. Pursuant to the Kyoto Protocol, adopting countries were required to implement national programs to reduce emissions of greenhouse gases (“GHGs”). The Kyoto Protocol was effectively replaced by the Paris Agreement. Emissions of greenhouse gases from international shipping were not subject to the Kyoto Protocol and currently are not subject to the Paris Agreement.

On July 15, 2011, the IMO approved mandatory measures to reduce emissions of greenhouse gases from international shipping. The amendments to Annex VI to MARPOL for the prevention of air pollution from ships add a new Chapter 4 to Annex VI on energy efficiency requiring the Energy Efficiency Design Index (“EEDI”) for new ships, and the Ship Energy Efficiency Management Plan (“SEEMP”) for all ships. The regulations apply to all ships of 400 gross tonnage and above and entered into force on January 1, 2013. These rules will likely affect the operations of vessels that are registered in countries that are signatories to Annex VI to MARPOL or vessels that call upon ports located within such countries. The IMO also adopted a mandatory data collection system requirement in October 2016 (“IMO DCS”) that requires ships of 5000 gross tonnage and above to record and report their fuel oil consumption, indirectly addressing carbon dioxide emissions data. The requirement was entered into force on March 1, 2018. These requirements could cause us to incur additional compliance costs.

The IMO is also taking steps toward the development of a market-based mechanism for greenhouse gas emissions from ships. At the October 2016 Marine Environmental Protection Committee (“MEPC”) session, the IMO adopted a roadmap for developing a comprehensive IMO strategy on reduction of GHG emissions. In April 2018, the MEPC adopted an initial strategy designed to reduce GHG emissions from vessels, including short-term, mid-term and long-term candidate measures with a vision of reducing and phasing out GHG emissions from vessels as soon as possible in the 21st Century. In June 2021, the MEPC adopted amendments to MARPOL Annex VI that enter into force on November 1, 2022 and establish an enforceable regulatory framework to reduce GHG emissions from international shipping, consisting of technical and operational carbon reduction measures. These measures include use of an Energy Efficiency Existing Ship Index (“EEXI”), an operational Carbon Intensity Indicator “CII”) and an enhanced SEEMP to drive reductions in the carbon intensity. A vessel’s attained EEXI will be calculated in accordance with values established based on type and size category, which compares the vessels’ energy efficiency to a baseline. A vessel is then required to meet a specific EEXI based on a required reduction factor expressed as a percentage relative to the EEDI baseline. Under the MARPOL VI amendments, vessels with a gross tonnage of 5,000 or greater must determine their required annual operational CII and their annual carbon intensity reduction factor needed to ensure continuous improvement of the vessel’s CII. On an annual basis, the actual annual operational CII achieved would be documented and verified against the vessel’s required annual operational CII to determine the vessel’s operational carbon intensity rating on a performance level scale of A (major superior) to E (inferior). The performance level would be required to be recorded in the vessel’s SEEMP. A vessel with an E rating, or three consecutive years of a D (minor inferior) rating, would be required to submit a corrective action plan showing how the vessel would achieve a C (moderate) rating. The requirements for EEXI and CII certification included in the MARPOL Annex VI amendments took effect January 1, 2023, which means the first annual reporting will be completed in 2023 and the first rating given in 2024. The MEPC regulatory approach is consistent with the IMO’s GHG strategy target of a 40% carbon intensity reduction for international shipping by 2030, as compared to 2008.

In the United States, the EPA issued an “endangerment finding” regarding greenhouse gases under the Clean Air Act. While this finding in itself does not impose any requirements on our industry, it authorizes the EPA to regulate directly greenhouse gas emissions through a rule-making process. In addition, from time to time climate change initiatives have been or are considered in the United States Congress and by individual states and may be considered in the future. In June 2013, the European Commission developed a strategy to integrate maritime emissions into the overall EU strategy to reduce greenhouse gas emissions. In accordance with this strategy, in April 2015 the European Parliament and Council adopted regulations (EU Directive 2015/757 or EU MRV Regulation) requiring vessels exceeding 5,000 gross tons using EU ports to monitor, report and verify their carbon dioxide emissions beginning in January 2018, with the first reports due in June 2019. In February 2019, the European Commission adopted a proposal to amend the EU MRV Regulation to harmonize the requirements of the EU MRV Regulation and the IMO DCS. On September 15, 2020, the European Parliament adopted measures to include maritime transport in the EU's Emissions Trading System as of 2022 and to set binding requirements for at least a 40% reductions in GHG emissions by shipping companies by 2030.

Although it is no longer a part of the EU MRV regime, the United Kingdom retained in domestic law the EU regulation establishing the EU MRV, subject to amendments required for the make the regulation applicable in a United Kingdom-only context.

Operators of ships over 5,000 gross tons using ports in the United Kingdom are expected to begin collecting emissions data for their ships commencing January 1, 2022 for the 2022 reporting period.

Any passage of climate control legislation or other regulatory initiatives by the IMO, the United States, the United Kingdom, the EU, Norway, Brazil or other countries where we operate, that restrict GHG emissions could have a significant financial and operational impact on our business, including requiring us to make significant financial expenditures that we cannot predict with certainty at this time. For example, the Paris Agreement could lead to increased regulation of greenhouse gases or other concerns relating to climate change. In addition, even without such regulation, our business may be indirectly affected to the extent that climate change results in sea level changes or more intense weather events.

Vessel Security Regulation

Since the terrorist attacks of September 11, 2001, there have been a variety of initiatives intended to enhance vessel security. On November 25, 2002, the Maritime Transportation Security Act of 2002 (the “MTSA”), came into effect in the United States. To implement certain portions of the MTSA, in July 2003, the U.S. Coast Guard issued regulations requiring the implementation of certain security requirements aboard vessels operating in waters subject to the jurisdiction of the United States. Similarly, in December 2002, amendments to SOLAS created a new chapter of the convention dealing specifically with maritime security. The maritime security chapter came into effect in July 2004 and imposes various detailed security obligations on vessels and port authorities, most of which are contained in the ISPS. The ISPS is designed to protect ports and international shipping against terrorism. After July 1, 2004, to trade internationally, a vessel must maintain an International Ship Security Certificate (“ISSC”) from a recognized security organization approved by the vessel’s flag state.

Among the various requirements are:

The U.S. Coast Guard regulations, intended to align with international maritime security standards, exempt non-U.S. vessels from the MTSA vessel security measures provided such vessels have onboard a valid ISSC that attests to the vessel’s compliance with SOLAS security requirements and the ISPS. KNOT has implemented the various security measures addressed by the MTSA, SOLAS and the ISPS.

Taxation of the Partnership

Certain of our subsidiaries are subject to taxation in the jurisdictions in which they are organized, conduct business or own assets. We intend that our business and the business of our subsidiaries will be conducted and operated in a manner designed to minimize the tax imposed on us and our subsidiaries. However, we cannot assure this result as tax laws in these or other jurisdictions may change or we may enter into new business transactions relating to such jurisdictions, which could affect our tax liability.

Marshall Islands

Because we and our subsidiaries do not carry on business or conduct transactions or operations in the Republic of the Marshall Islands, neither we nor our subsidiaries are subject to income, capital gains, profits or other taxation under current Marshall Islands law, other than taxes, fines or fees due to (i) the incorporation, dissolution, continued existence, merger, domestication (or similar concepts) of legal entities registered in the Republic of the Marshall Islands, (ii) filing certificates (such as certificates of incumbency, merger, or re-domiciliation) with the Marshall Islands registrar, (iii) obtaining certificates of good standing from, or certified copies of documents filed with, the Marshall Islands registrar, (iv) compliance with Marshall Islands law concerning record keeping and vessel ownership, such as tonnage tax, or (v) non-compliance with economic substance regulations or requests made by the Marshall Islands Registrar of Corporations relating to our books and records and the books and records of our subsidiaries. As a result, distributions KNOT UK receives from its subsidiary, distributions that such subsidiary receives from the operating subsidiaries, and distributions we receive from KNOT UK, are not expected to be subject to Marshall Islands taxation.

United States

We have elected to be treated as a corporation for U.S. federal income tax purposes. As a result, we are subject to U.S. federal income tax to the extent we earn income from U.S. sources or income that is treated as effectively connected with the conduct of a trade or business in the United States unless such income is exempt from tax under an applicable treaty or Section 883 of the Code. Because our fleet is owned by subsidiaries resident in Norway, we expect that we qualify for an exemption from U.S. federal income tax on any U.S. source gross transportation income we earn by virtue of the application of the U.S.-Norway Tax Treaty, and we intend to take this position for U.S. federal income tax purposes. Moreover, we do not expect to earn any income that is effectively connected with the conduct of a trade or business in the United States.

Norway

We are treated as fiscally transparent for Norwegian tax purposes and expect to organize our affairs and conduct our business in a manner such that we, and our remaining subsidiaries that are not organized under the laws of the Kingdom of Norway, are not subject to a material amount of Norwegian taxes.

Our vessel-owning subsidiaries have been organized under the laws of the Kingdom of Norway and are subject to the tonnage tax regime in Norway. Pursuant to this regime, our vessel-owning subsidiaries will be subject to Norwegian tax based predominantly upon the net tonnage of their owned vessels rather than income generated from operating the vessels (i.e., operating income). Based upon the net tonnage of our current vessels and the applicable rate of taxation, our Norwegian subsidiaries are liable for approximately $236,364 of Norwegian tonnage tax for the year ended December 31, 2022. In addition, under the tonnage tax regime, net financial income (i.e. income not generated from operating vessels) is subject to the regular Norwegian corporate income tax rate.

On December 14, 2017, the Norwegian government concluded negotiations with the EFTA Surveillance Authority regarding the Norwegian tonnage tax regime, which has been approved for another ten years until 2027. Pursuant to the approval, Norway has introduced restrictions that eliminate the ability of companies that operate vessels under certain bareboat charters to qualify for the Norwegian tonnage tax regime. Companies that no longer qualify for the Norwegian tonnage tax regime will instead be subject to regular Norwegian corporate income tax. However, there are no limitations on intra-group bareboat chartering, as well as bareboat charters where crewing services are carried out by a related party. In order to constitute a related party, a minimum of 25% joint ownership/control is required according to the Norwegian General Taxation Act Section 8-13, paragraph 6. Because KNOT owns more than 25% of our partnership interests and owns 100% of KNOT Management and KNOT Management Denmark (which provide these crewing services to us), our bareboat charters are effectively seen as time charter services to the customer. If this related party situation is ended, other alternatives and possibly mitigating measures would need to be evaluated by the Partnership.

The United Kingdom’s withdrawal and exit from EU, commonly referred to as “Brexit”, took place on January 31, 2020. Even though the U.K. formally left the EU at that date, UK continued to follow the EU rules during a transition period, which ended on December 31, 2020. In order to meet any future national flag requirements pursuant to the Norwegian tonnage tax regime, we have reflagged some of our previously U.K.-flagged vessels to an EU/European Economic Area (“EEA”) flag. Whether there will be a flag requirement for any year is announced in September/October of that year. On September 26, 2022, it was announced that the flag requirement was applicable for the year ended December 31, 2022.Our Norwegian vessel-owning subsidiaries were compliant with the flag requirement in 2022.

Further, as from January 1, 2021, as the Brexit transition period has ended, the domestic Norwegian legislation providing exemption of withholding tax on outbound dividends from KNOT Shuttle Tankers AS to KNOT UK is no longer applicable, as this exemption rule only includes dividend distributions to corporate shareholders within the EU/EAA. However, we expect that dividends from KNOT Shuttle Tankers AS to KNOT UK are still exempt from withholding tax pursuant to the double tax treaty between Norway and the U.K.

United Kingdom

Although we are managed and controlled in the United Kingdom, we have obtained confirmation from HM Revenue & Customs that we are treated as a transparent partnership for United Kingdom tax purposes. Accordingly, we are not subject to U.K. tax in our own name, but rather any partners subject to U.K. tax will be taxed on their share of our profits.

Our general partner and KNOT UK expect to be a resident of the United Kingdom for taxation purposes subject to tax on ordinary income. Nonetheless, these companies are primarily expected to earn dividend income from our controlled affiliates, which should generally be exempt from United Kingdom taxation under applicable exemptions for distributions from subsidiaries.

Employees

We directly employ one onshore employee and no seagoing employees. As of December 31, 2022, KNOT employed (directly and through ship managers) approximately 694 seagoing staff to serve on our vessels. KNOT and its affiliates may employ additional seagoing staff to assist us as we grow. KNOT, through certain of its subsidiaries, provides onshore advisory, commercial, technical and operational support to our operating subsidiaries pursuant to the technical management agreements and management and administration agreements. Please read “Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions.”

We and KNOT regard attracting and retaining motivated seagoing personnel as a top priority. KNOT offers seafarers competitive employment packages and opportunities for personal and career development, which relates to a philosophy of promoting internally. The officers operating our vessels are engaged on individual employment contracts, and we have entered into collective bargaining agreements that cover substantially all of the sailing personnel that operate the vessels in our current fleet, which are flagged in Norway, the Isle of Man, Malta, Denmark, United Kingdom or the Bahamas. We believe our relationships with these labor unions are good. Our commitment to training is fundamental to the development of the highest caliber of seafarers for our marine operations. KNOT’s cadet training approach is designed to balance academic learning with hands-on training at sea. KNOT trains personnel mainly in Norway and the Philippines and at institutions that utilize ship handling, dynamic positioning and cargo handling simulators. After receiving formal instruction at one of these institutions, our seafarers’ training continues onboard one of KNOT’s vessels. Additional vessel and equipment training and courses are arranged in accordance with our training policies and the training requirements of our charterers. We believe that high-quality crewing and training policies will play an increasingly important role in distinguishing the larger, independent shipping companies with shuttle tanker experience from those that are newcomers and lack experienced, in-house staff and established expertise on which to base their customer service and safety operations.

payment of $72.3 million due at maturity in October 2025 which includes the balloon payment and last quarterly installment. The Synnøve Facility bears interest at an annual rate equal to LIBOR plus a margin of 1.75%. The purchase price was settled in cash.

The Synnøve Knutsen is operating in Brazil under a time charter with Equinor, which will expire in February 2027. The charterer has options to further extend the charter for up to three two-year periods and nine one-year periods. Our board of directors (the “Board”) and the conflicts committee of the Board (the “Conflicts Committee”) approved the purchase price of the Synnøve Acquisition. The Conflicts Committee retained an outside financial advisor and outside legal counsel to assist with its evaluation of the Synnøve Acquisition.

Windsor Knutsen

In September 2021, the Windsor Knutsen commenced on a one-year time charter contract with PetroChina. The Windsor Knutsen was redelivered from her time charter with PetroChina on June 14, 2022 to start on her mobilization trip to Europe for her planned 15-year special survey drydocking. On the same date, the Vigdis Knutsen, having successfully completed her own drydocking, replaced the Windsor Knutsen on the time charter contract for PetroChina.

The Windsor Knutsen successfully completed her drydock, departing the yard in early August 2022 bound for Brazil in September 2022. In October 2022, the Windsor Knutsen suffered a hydraulic leak from a bow thruster and the vessel was placed off hire. However, except for a deductible of 14 days, loss of hire insurance is expected to provide income potentially lost due to the incident, and hull and machinery insurance is expected to cover the majority of any costs incurred to repair above the deductible amount. The Windsor Knutsen returned to service in November 2022 and performed one spot voyage in late November and December 2022.

In August 2022, the Partnership agreed the commercial terms for a new time charter contract for the Windsor Knutsen with Shell to commence in or around January 2023 for a fixed period of one year with a charterer’s option to extend the charter by one further year. The Windsor Knutsen was delivered to Shell on January 11, 2023. The Windsor Knutsen has a time charter contract with Equinor that will commence in the fourth quarter of 2024 or the first quarter of 2025 for a fixed period, at the charterer’s option, of either one year or two years, with options for the charterer to extend the charter, in either case, by two further one-year periods.

Bodil Knutsen

The Bodil Knutsen operated a rolling one-month time charter contract with a subsidiary of the Partnership’s sponsor, KNOT, at a reduced charter rate until March 7, 2023. From that date, the Bodil Knutsen has operated under a time charter to KNOT on a fixed-term basis at the same reduced charter rate. This time charter expires on or around December 31, 2023, or at such time as the vessel is to be delivered to Equinor, if earlier. The Bodil Knutsen has a time charter contract with Equinor that will commence in the fourth quarter of 2023 or the first quarter of 2024, for an initial fixed charter period of two years, with charterer’s options to extend the charter by two further one-year periods.

Hilda Knutsen

The Hilda Knutsen was redelivered from Eni to the Partnership on September 3, 2022. In the interim period, the Partnership and KNOT agreed for KNOT to charter the Hilda Knutsen under a rolling time charter contract that commenced on September 3, 2022, at a reduced rate and which now expires in January 2024 unless terminated by either party on giving not less than 30 days’ notice. The Partnership is continuing to market the vessel for new, third-party time charter employment.

Torill Knutsen

The Torill Knutsen was redelivered from Eni to the Partnership on December 17, 2022, and the vessel subsequently performed a number of spot voyages, including in the conventional tanker market. Since March 1, 2023 the vessel has operated under a time charter to KNOT on a fixed-term basis that expires on or around December 31, 2023 at a reduced charter rate. The Partnership is continuing to market the vessel for new, third-party time charter employment.

Fortaleza Knutsen and Recife Knutsen

The current bareboat charters of the Fortaleza Knutsen and the Recife Knutsen with Transpetro are due to expire in March 2023 and August 2023, respectively. The Partnership agreed commercial terms for a new three-year time charter contract for each of these two vessels with the existing charterer to commence directly upon expiration of the existing bareboat charters. The new charter for the Fortaleza Knutsen was signed on March 28, 2023 and commenced on March 30, 2023, and the contract for the Recife Knutsen is expected to be signed in April 2023 and commence on or around August 3, 2023. Once signed, the vessels will be fixed until March 2026 and August 2026, respectively.

Carmen Knutsen

On November 29, 2022, Repsol Sinopec, the charterer of the Carmen Knutsen, confirmed its option to extend the existing time charter of the vessel by one further year and the vessel is now fixed until January 2024, with Repsol Sinopec holding options to extend the time charter by two further one-year periods.

The Carmen Knutsen was redelivered from the charterer on December 12, 2022 to start her mobilization trip to Europe for her planned 10-year special survey drydocking which was successfully completed, and on February 24, 2022 the vessel recommenced under the charter with Repsol Sinopec.

Ingrid Knutsen

In accordance with the time charter agreement with Eni for the Ingrid Knutsen, the vessel was returned to the Partnership on January 2, 2023, and the vessel subsequently performed a number of spot voyages, including in the conventional tanker market. On February 17, 2023, the Partnership entered into a new fixed ten-month time charter contract with Altera which commenced on March 2, 2023. The Ingrid Knutsen has a time charter contract with Eni that will commence in January 2024 for a fixed period of three years, with Eni having options to extend the charter by up to three further years.

Tordis Knutsen

The Tordis Knutsen was redelivered from the charterer on November 26, 2021, and thereafter started on her mobilization trip to Europe for her planned 5-year special survey drydocking. The vessel completed this work and on February 23, 2022 the vessel commenced a new time charter contract with Petrobras for a fixed period of five months with an option for the charterer to extend the charter by one month.

The Tordis Knutsen was redelivered from Petrobras on August 24, 2022. The vessel commenced on a new time charter contract with a subsidiary of TotalEnergies on September 10, 2022 for a fixed period of three months, with charterer’s options to extend the charter by up to two further three-month periods. TotalEnergies has exercised both of these options, and therefore the vessel is now fixed until June 2023, at which time the Tordis Knutsen is expected to be delivered to Shell to commence on a three-year time charter contract.

Lena Knutsen

The Lena Knutsen was redelivered to the Partnership on June 2, 2022 in advance of the commencement of the vessel’s planned five-year special survey drydocking in Europe. After drydocking, the Lena Knutsen returned to Brazil in early August 2022. The Partnership entered into a new time charter agreement for the Lena Knutsen with a subsidiary of TotalEnergies which commenced on August 21, 2022. The charter is for a fixed period of six months with charterer’s options to extend the charter by up to six further months. In January 2023, TotalEnergies exercised the option and the charter will expire on or around August 2023, at which time the Lena Knutsen is expected to be delivered to Shell to commence on a three-year time charter contract.

Brasil Knutsen

The current time charter for the Brasil Knutsen with Galp expired in November 2022; however, the Partnership has entered into a new time charter contract with Petrogal, a subsidiary of Galp, in direct continuation, for a period of one year, extending the vessel’s firm employment to November 2023.

Vigdis Knutsen

The Vigdis Knutsen was redelivered to the Partnership on March 5, 2022 in advance of the commencement of the vessel’s planned five-year special survey drydocking in Europe. After drydocking, the vessel returned to Brazil in June 2022 and on June 14, 2022 the Vigdis Knutsen replaced the Windsor Knutsen on the time charter contract for PetroChina as Windsor Knutsen started on her mobilization trip to Europe for her planned 15-year special survey drydocking. On September 15, 2022, PetroChina exercised its first extension option for an additional period of 12 months, extending the firm period of the charter to September 2023, and at the same time the time charter contract was novated to China Offshore Oil (Singapore), International Pte. Ltd., a company within the same group as PetroChina. The charterer has one further six-month charter extension option.

Anna Knutsen

The Anna Knutsen was redelivered from the charterer on February 14, 2022 and started on her mobilization trip to Europe in order to complete her planned 5-year special survey drydocking. On February 11, 2022, the Partnership entered into a new time charter contract for the Anna Knutsen with TotalEnergies for two years, with options for the charterer to extend the time charter by up to three further one-year periods. The charter commenced on April 28, 2022, immediately after the vessel returned to Brazil following completion of the drydock.

Reduction in Common Unit Distribution

On January 11, 2023, we reduced our quarterly common unit distribution to $0.026 per unit. We expect to continue to use our internally generated cash flow to provide for working capital, reduce our debt levels and strengthen our balance sheet.

Our Charters

We generate revenues by charging customers for the hire of our vessels and for services related to the transportation of their crude oil using our vessels. These services are provided under the following basic types of contractual relationships:

Market Overview and Trends

As of March 30, 2023, the shuttle tanker market consisted of approximately 75 vessels plus 6 newbuilds on order, characterized by mid to long-term charters with offshore oil producers. Most shuttle tankers operate in the North Sea or offshore Brazil.

Demand for shuttle tankers is based on offshore oilfield development and prior to mid-2014, higher oil prices and a positive long-term offshore oil outlook led to increased activity. During 2015-2018, oil companies delayed certain oil production start-ups in both the North Sea and Brazil. In 2019, there were increased project startups.

Then, following announcements made during the COVID-19 crisis in 2020 by many of the large oil exploration and production companies, near-term capital expenditure cuts were again seen, delaying many new developments in Brazil and the North Sea by an expected 12 - 24 months. These announcements also indicated to the Partnership that these projects would not be cancelled. This assumption is supported by the relatively low costs of oil production in the North Sea and especially Brazil, the rebound in both oil prices and, to a degree, current global oil demand and FPSO activity, particularly in Brazil where market activity has already strengthened as oil production has increased.

Brazil has continued on a path to higher offshore deepwater oil production and on November 30, 2022, Petrobras signaled that its investments had returned to pre-COVID levels as it approved its Strategic Plan for 2023-2027. In the plan, Petrobras is committing around $42 billion of capex to Pre-salt exploration and production, all related to projects that on average remain viable at a long-term Brent oil price of $35 per barrel, and while keeping on-track with its 2030 low-carbon intensity goals (Brazil’s pre-salt region is known for its highly productive wells and has some of the lowest carbon intensity levels seen globally).

Already several new FPSO platforms are expected to start operating in 2023 across the Marlim, Búzios, and Mero fields. As these and other new platforms commence operations, we believe that demand for shuttle tankers in Brazil, where fourteen of our vessels typically operate, will strengthen, and continue into the mid and long term.

The dampened demand in the North Sea shuttle tanker market as a result of production and project delays, as well as maintenance and upgrades in the Balder and Njord fields, could persist throughout 2023. However, we continue to expect the market to rebalance as customers move forward with offshore projects that were postponed or delayed, as countries increasingly prioritize oil production due to high oil prices and energy security concerns, and as some older vessels also naturally exit the shuttle tanker market. Such macro variables make forecasting the specific timing of this rebalancing more difficult.

We also face risks and trends that could adversely affect our industry and business. Energy rebalancing trends have accelerated in recent years as evidenced by promulgated or proposed government policies and commitments by many of our customers to further invest in sustainable energy sources. Our industry could be further challenged as our customers rebalance their capital investments to include alternative energy sources, as well as respond to the normal cycles that have historically existed in our industry. We also expect some inflationary pressures to persist in 2023.

65

Table of Contents

We believe that demand for existing and for newbuild shuttle tankers will continue to be driven over the long term, based on the requirement to replace older tonnage in the North Sea and from further expansion of deep and ultra-deep water offshore oil production in areas such as Pre-salt Brazil and the Barents Sea. We therefore remain positive with respect to the mid-to-long-term outlook for the growth in demand for shuttle tankers and the opportunities that this will present.

The statements in this “Market Overview and Trends” section are forward-looking statements based on management’s current expectations and certain material assumptions and, accordingly, involve risks and uncertainties that could cause actual results, performance and outcomes to differ materially from those expressed herein. See “Item 3. Key Information—Risk Factors.”

COVID-19

The outbreak and repercussions from the COVID-19 pandemic continue to affect global economic activity. However, the Partnership has to date avoided any serious or sustained operational impacts, and there have been no effects on the Partnership’s contractual position. There has been much progress in vaccinations and global economies appear to be recovering, which continue to cautiously increase optimism.

The Partnership’s focus remains on ensuring the health and safety of its employees and crew onboard while providing safe and reliable operations for its customers, and a large number of practical steps and changes have been made and taken towards this aim. While full or partial crew changes on all of the Partnership’s vessels have been continuing, the situation remains challenging for the maritime industry as a whole, not the least as a result of increased travel and logistics time and costs.

Costs related to the movement of maritime personnel and vessel operational logistics, including repairs and maintenance, remain challenging. The Partnership remains vigilant to address any changes related to the health, safety and wellbeing of personnel, or to government restrictions and other matters potentially affecting operations. Other than 17 days of off-hire incurred as a result of a COVID-19 outbreak on the Vigdis Knutsen in July 2021 which was quickly contained with no serious ill-health caused to any persons affected, the Partnership has not had any material service interruptions on its time-chartered vessels as a result of COVID-19.

The closure of, or restricted access to, ports and terminals and passenger air travel in regions affected by the virus could lead to further operational impacts that could result in higher costs. It is possible that a further outbreak onboard a time-chartered vessel could prevent the Partnership from meeting its obligations under a charter, resulting in an off-hire claim and loss of revenue. Any outbreak of COVID-19 on board one of the Partnership’s time-chartered vessels or that affects any of the Partnership’s main suppliers could cause an inability to replace critical supplies or parts, maintain adequate crewing or fulfill the Partnership’s obligations under its time charter contracts, which in turn could result in off-hire or claims for the impacted period.

Announced delays in new capital expenditure by many oil majors in 2020 and 2021 had a negative impact on the demand for shuttle tankers. This affected the timing and number of new, offshore projects and overall oil production profiles in the short-term, which impacted the demand and pricing for shuttle tankers. If this situation persists the Partnership may be unable to re-charter its vessels at attractive rates in the future, particularly for vessels that are coming off charter in the next one to two years. Notwithstanding these challenges, the Partnership remains confident in the mid to long term growth opportunities for the shuttle tanker market and that as economic activity begins to regain traction, the Partnership will be well-placed to capture new opportunities, particularly given an absence of speculative vessel ordering in the shuttle tanker sector.

Although the Partnership is exposed to credit risk associated with individual charterers, the Partnership believes that its charter contracts, all with subsidiaries of national oil companies and oil majors and KNOT, largely insulate the Partnership from this risk. In particular, charter hire is payable in advance and the services the Partnership performs are of a critical nature for the Partnership’s customers. Notwithstanding, any extended period of non-payment or idle time between charters could adversely affect the Partnership’s future liquidity, results of operations and cash flows. The Partnership has not so far experienced any reduced or non-payments for obligations under the Partnership’s time charter contracts and the Partnership has not provided concessions or made changes to the terms of payment for customers.

The Partnership’s time charter contracts include both a lease component, consisting of the lease of the vessel, and non-lease component, consisting of operation of the vessel for the customers. The lease element is accounted for as an operating lease on a straight-line basis over the term of the charter, while the service element consisting of the operation of the vessel is recognized over time as the services are delivered. Revenue from time charters is not recognized during days a vessel is off-hire. Revenue is recognized from delivery of a vessel to the charterer, until the end of the contract period. Under bareboat charters, the Partnership provides a specified vessel for a fixed period of time at a specified day rate and the Partnership recognizes revenues from bareboat charters as operating leases on a straight-line basis over the term of the charter. Revenues are affected by hire rates and the number of days a vessel operates as well as the mix of business between time charters and bareboat charters.

Voyage Revenues. Voyage revenues are all revenues unique to a particular spot voyage.

Voyage Expenses. Voyage expenses are all expenses unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls and agency fees. Voyage expenses are typically paid by the customer under time charters and bareboat charters. Voyage expenses are paid by the shipowner during spot contracts and periods of off-hire and are recognized when incurred.

Vessel Operating Expenses. Vessel operating expenses include crewing, repairs and maintenance, insurance, stores, lube oil and communication expenses. Vessel operating expenses are generally paid by the shipowner under time charters and spot contracts and are recognized when incurred. Vessel operating expenses are paid by the customer under bareboat charters.

Off-hire. Under our time charters, when the vessel is off-hire, or not available for service, the customer generally is not required to pay the hire rate, and the shipowner is responsible for all costs. Prolonged off-hire may lead to a termination of the time charter. A vessel generally will be deemed off-hire if there is a loss of time due to, among other things, operational deficiencies, drydocking for repairs, maintenance or inspection, equipment breakdowns, delays due to accidents, crewing strikes, certain vessel detentions or similar problems or the shipowner’s failure to maintain the vessel in compliance with its specifications and contractual standards or to provide the required crew. Our bareboat charters do not contain provisions for off-hire. We have obtained loss of hire insurance to protect us against loss of income in the event one of our vessels cannot be employed due to damage that is covered under the terms of our hull and machinery insurance. Under our loss of hire policies, our insurer generally will pay us the hire rate agreed in respect of each vessel for each day in excess of 14 days and with a maximum period of 180 days.

Drydocking. We must periodically drydock each of our vessels for inspection, repairs and maintenance and any modifications required to comply with industry certification or governmental requirements. In accordance with industry certification requirements, we drydock our vessels at least every 60 months until the vessel is 15 years old, after which drydocking takes place at least every 30 months thereafter as required for the renewal of certifications required by classification societies. For vessels operating on time charters, we capitalize the costs directly associated with the classification and regulatory requirements for inspection of the vessels and improvements incurred during drydocking that increase the earnings capacity or improve the efficiency or safety of the vessels. We expense costs related to routine repairs and maintenance performed during drydocking or as otherwise incurred. For vessels operating on bareboat charters, the customer bears the cost of any drydocking. The number of drydockings undertaken in a given period and the nature of the work performed determine the level of drydocking expenditures.

Depreciation. Depreciation on vessels and equipment is calculated on a straight-line basis over the asset’s estimated useful life of 23 years for the hull and equipment, less an estimated residual value. Drydocking cost is depreciated on a straight-line basis over the period until the next planned drydocking takes place. For vessels that are newly built or acquired, an element of the cost of the vessel is allocated initially to a drydock component and depreciated on a straight-line basis over the period until the next planned drydocking. When significant drydocking expenditures occur prior to the expiration of this period, we expense the remaining balance of the original drydocking cost in the month of the subsequent drydocking.

Impairment of Long-Lived Assets. Vessels and equipment, vessels under construction and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

Other Finance Expense. Other finance expense includes external bank fees, financing service fees paid to related parties and guarantee commissions paid to external parties in connection with our debt and other bank services.

Revenue Days. Revenue days are the total number of calendar days our vessels were in our possession during a period, less the total number of off-hire days during the period associated with major repairs, or drydockings. Consequently, revenue days represent the total number of days available for the vessel to earn revenue. Idle days, which are days when the vessel is available to earn revenue, yet is not employed, are included in revenue days. We use revenue days to highlight changes in net voyage revenues between periods.

Average Number of Vessels. The historical average number of vessels consists of the average number of owned vessels that are in our possession during the periods presented. We use average number of vessels primarily to highlight changes in vessel operating expenses, hire rate expense and depreciation and amortization.

Insurance

Hull and Machinery Insurance. We have obtained hull and machinery insurance on all our vessels to insure against marine and war risks, which include the risks of damage to our vessels, salvage and towing costs, and also insures against actual or constructive total loss of any of our vessels. However, our insurance policies contain deductible amounts for which we are responsible. We have also arranged additional total loss coverage for each vessel. This coverage, which is called hull interest and freight interest coverage, provides us additional coverage in the event of the total loss or the constructive total loss of a vessel.

Loss of Hire Insurance. We have obtained loss of hire insurance to protect us against loss of income in the event one of our vessels cannot be employed due to damage that is covered under the terms of our hull and machinery insurance. Under our loss of hire policies, our insurer will pay us the hire rate agreed in respect of each vessel for each day, in excess of a certain number of deductible days, for the time that the vessel is out of service as a result of damage, for a maximum of 180 days. The number of deductible days for the vessels in our fleet is 14 days per vessel.

All of our hull and machinery, hull interest and freight interest and loss of hire insurance policies are written on the NMIP, which through the hull and maintenance coverage also offers comprehensive collision liability coverage of up to the insured hull and maintenance value of the vessel. NMIP is based on an “all risk principle” and offers what is considered to be the most comprehensive insurance obtainable in any of the world’s marine markets today. The agreed deductible on each vessel averages $150,000.

Protection and Indemnity Insurance. Protection and indemnity insurance, which covers our third-party legal liabilities in connection with our shipping activities, is provided by a P&I club. This includes third-party liability and other expenses related to the injury or death of crew members, passengers and other third-party persons, loss or damage to cargo, claims arising from collisions with other vessels or from contact with jetties or wharves and other damage to other third-party property, including pollution arising from oil or other substances, and other related costs, including wreck removal. Our current protection and indemnity insurance coverage is unlimited, except for pollution, which is limited to $1 billion per vessel per incident.

Time charter and bareboat revenues: Time charter and bareboat revenues for the year ended December 31, 2022 were $262.8 million, a decrease of $6.5 million compared to $269.3 million for the year ended December 31, 2021. The decrease was principally due to (i) off-hire in connection with scheduled drydockings for the Tordis Knutsen, the Anna Knutsen, the Vigdis Knutsen, the Lena Knutsen and the Windsor Knutsen; (ii) reduced earnings from the Windsor Knutsen which shortly after completing her planned 15-year special survey drydocking in Europe suffered a hydraulic leak from a bow thruster, which placed the vessel off hire until November 2022; (iii) decreased earnings from the Carmen Knutsen which was redelivered from the charterer in mid-December 2022 to start her mobilization trip to Europe for her planned 10-year special survey drydocking; and (iv) reduced hire rates on certain vessels. This decrease was partially offset by Synnøve Knutsen being included in results of operations as of July 1, 2022.

Voyage revenues: Voyage revenues for the year ended December 31, 2022, were $4.7 million. The voyage revenues relate to spot voyages performed by the Windsor Knutsen and the Torill Knutsen.

Loss of hire insurance recoveries: Loss of hire insurance recoveries for the year ended December 31, 2022, were $0.8 million compared to $11.5 million for the year ended December 31, 2021. The loss of hire insurance recoveries for the year ended December 31, 2022, were related to the Vigdis Knutsen. In April 2022, during scheduled drydock, excessive and abnormal wear was found on the steering gear rotor. The Vigdis Knutsen was in drydock and off-hire from March 3, 2022 to June 14, 2022 for its scheduled drydock. The drydock was extended due to the repairs on the steering gear rotor. The loss of hire insurance recoveries for the year ended December 31, 2021 were related to the Windsor Knutsen in connection with repairs to her main engine block, the Tove Knutsen in connection with a leakage from its controllable pitch propeller and the Tordis Knutsen due to a technical fault on its azimuth thruster. As a result, the Windsor Knutsen was off-hire from December 12, 2020 to June 10, 2021, the Tove Knutsen was off-hire from March 1, 2021 to April 15, 2021 and the Tordis Knutsen was off-hire from July 17, 2021 to August 25, 2021.

Other income: Other income for the year ended December 31, 2022 was $0.3 million compared to $0.4 million for the year ended December 31, 2021.

Vessel operating expenses: Vessel operating expenses for the year ended December 31, 2022 were $86.0 million, an increase of $13.9 million from $72.1 million for the year ended December 31, 2021. The increase is mainly related to bunker costs for the Tordis Knutsen, the Anna Knutsen, the Vigdis Knutsen, the Lena Knutsen, the Windsor Knutsen and the Carmen Knutsen in connection with their voyages to their scheduled drydock in Europe. The increase is also related to the Synnøve Knutsen being included in the results of operation as from July 1, 2022.

Voyage expenses and commission: Voyage expenses and commission for the year ended December 31, 2022, were $2.8 million. The voyage expenses and commission relate to bunker cost, commission and port cost for spot voyages performed by the Windsor Knutsen and the Torill Knutsen.

Depreciation: Depreciation expense for the year ended December 31, 2022 was $107.4 million, an increase of $7.8 million from $99.6 million for the year ended December 31, 2021. The increase is mainly related to the change by the Partnership of the useful life estimate of each of the vessels in its fleet from 25 years to 23 years due to prevailing longer-term market trends, which increased the non-cash accounting depreciation charge starting July 1, 2021, and to the Synnøve Knutsen being included in the results of operations from July 1, 2022.

Impairment: Impairment charge for the year ended December 31, 2022 was $nil compared to $29.4 million for year ended December 31, 2021. The impairment charge for the year ended December 31, 2021, was related to the Windsor Knutsen as a result of the vessel’s high carrying value which in turn arose due to the cost of both the purchase and the conversion of the vessel to a shuttle tanker from a conventional tanker.

General and administrative expenses: General and administrative expenses for the year ended December 31, 2022 were $6.1 million compared to $6.5 million for the year ended December 31, 2021. The decrease is mainly related to higher legal and administration fees in 2021 connected with the IDR Exchange and the commencement of the ATM program.

Interest income: Interest income for the year ended December 31, 2022 was $0.8 million compared to $2,000 for the year ended December 31, 2021. The increase is mainly due to increased interest rates on our bank deposits.

Interest expense: Interest expense for the year ended December 31, 2022 was $42.6 million, an increase of $14.5 million from $28.1 million for the year ended December 31, 2021. The increase was mainly due to an increase in the US dollar LIBOR rate, increased interest expense for the credit facility related to the acquisition of the Synnøve Knutsen on July 1, 2022, increased interest expense on the revolving credit facilities and increased interest expense for the Torill Knutsen in connection with the sale and leaseback transaction in which both the financial obligation and interest rate increased.

Other finance expense: Other finance expense was $0.6 million for the year ended December 31, 2022, a decrease of $0.4 million from $1.0 million for the year ended December 31, 2021. Other finance expense is primarily related to bank fees and guarantee commissions.

Realized and unrealized gain (loss) on derivative instruments: Realized and unrealized gain on derivative instruments for the year ended December 31, 2022 was $35.5 million, compared to a gain of $10.0 million for the year ended December 31, 2021, as set forth in the table below:

​

​

As of December 31, 2022, the total notional amount of the Partnership’s outstanding interest rate swap contracts that were entered into in order to hedge outstanding or forecasted debt obligations was $451.2 million. All of the unrealized gain in the year ended December 31, 2022 is related to a mark-to-market gain on interest rate swaps.

Net gain (loss) on foreign currency transactions: Net gain on foreign currency transactions for the year ended December 31, 2022 was $0.2 million compared to a loss of $0.1 million for the year ended December 31, 2021.

Income tax expense: Income tax expense for the year ended December 31, 2022 was $0.9 million compared to $0.5 million for the year ended December 31, 2021. The increase is a result of higher net financial income, which is taxed at the normal Norwegian corporate tax rate in 2022.

Net income: As a result of the foregoing, the Partnership recorded net income of $58.7 million for the year ended December 31, 2022, compared to net income of $53.9 million for the year ended December 31, 2021.

On January 11, 2023, we reduced our quarterly common unit distribution to $0.026 per unit. We expect to continue to use our internally generated cash flow to provide for working capital, reduce our debt levels and strengthen our balance sheet. Our funding and treasury activities are intended to maximize investment returns while maintaining appropriate liquidity. Cash and cash equivalents are held primarily in U.S. Dollars with some balances held in NOK, British Pounds and Euros. We have not made use of derivative instruments other than for interest rate and currency risk management purposes, and we expect to continue to economically hedge part of our exposure to interest rate fluctuations in the future by entering into new interest rate swap contracts when suitable opportunities arise.

We estimate that we will spend in total approximately $55.4 million for drydocking and classification surveys for the vessels under time charters in our fleet as of December 31, 2022, between 2023 and 2027, with approximately $17.6 million of this amount to be spent in the twelve months ending December 31, 2023. As our fleet matures and expands, our drydocking expenses will likely increase. Ongoing costs for compliance with environmental regulations are primarily included as part of our drydocking and society classification survey costs or are a component of our vessel operating expenses. We are not aware of any regulatory changes or environmental liabilities that we anticipate will have a material impact on our current or future operations. There will be further costs related to voyages to and from the drydocking yard that will depend on the distance from the vessel's ordinary trading area to the drydocking yard.

As of December 31, 2022, the Partnership had available liquidity of $47.6 million, which consisted of cash and cash equivalents of $47.6 million. As of December 31, 2022, all of our revolving credit facilities had been fully drawn and we have no ability to incur additional debt under our existing credit facilities. The Partnership’s total interest-bearing obligations outstanding as of December 31, 2022 were $1,062.6 million ($1,056.4 million net of debt costs). The average margin paid on the Partnership’s outstanding debt during 2022 was approximately 2.02% over LIBOR.

As of December 31, 2022, the Partnership had total $1,148.7 million in outstanding obligations, which include installments and interest on long-term debt, sale and leaseback commitments in respect of the Raquel Knutsen and the Torill Knutsen, interest commitments on interest rate swaps and operating lease commitments. Of the total outstanding obligations, $409.7 million matures during the year ending December 31, 2023 and $739.0 million matures after such date.

In particular, our $320 million senior secured credit facility and $55 million revolving credit facility secured by the Windsor Knutsen, Bodil Knutsen, Fortaleza Knutsen, Recife Knutsen, Carmen Knutsen and Ingrid Knutsen mature in September 2023 and our $172.5 million senior secured loan facility secured by the Dan Cisne and Dan Sabia matures in September 2023 and January 2024. Finally, our two $25 million unsecured revolving credit facilities mature in August 2023 and November 2023.

The consolidated financial statements have been prepared assuming that the Partnership will continue as a going concern. As of December 31, 2022, the Partnership’s net current liabilities were $304.1 million. Included in current liabilities are $369.8 million of short-term loan obligations that mature before December 31, 2023 and are therefore presented as current debt.

The Partnership expects that its primary future sources of funds will be available cash, cash from operations, borrowings under any new loan agreements and the proceeds of any debt or equity financings, including net proceeds from sales under the ATM program.

As described above, the Partnership has significant debt coming due within one year. The Partnership has commenced discussions and negotiations with its lending group and other institutions and advisors concerning the refinancing of all of its credit facilities that mature in 2023 and early 2024. However, if the Partnership is not able to secure the refinancing of this debt, there will be insufficient liquid funds necessary to repay the debt at maturity. Although there is some judgment required in assessing this risk, given the negotiations that are already underway and given the Partnership’s history of successfully obtaining financing or refinancing its debt, management believes that it will be able to conclude a refinancing of all such facilities on similar terms (including that no re-leverage is required) prior to maturity. However, no assurance can be given that all such facilities will be timely refinanced on acceptable terms. Currently, we do not have any off-balance sheet arrangements.

Capital Expenditures

We reserve cash from operations for future maintenance capital expenditures, working capital and other matters.

Table of Contents

The Partnership’s future capital expenditure requirements principally relate to vessel drydocks. The Partnership expects to incur $17.6 million in 2023 on vessel drydocks and $2.2 million in 2023 on the installation of a ballast water treatment system on the Carmen Knutsen, all funded by cash from operations. Other than future drydocks and ballast water treatment system installation, as at December 31, 2022 and as at March 30, 2023, the Partnership has no other material capital expenditure commitments.
