STRATEGIC REPORT
FOR THE YEAR ENDED 31 DECEMBER 2024

Introduction
 
The directors present their Strategic Report for the year ended 31 December 2024.
The principal activity of the company is that of a holding company.
The principal activity of the subsidiaries is the operation of supply vessels and transportation from onshore supply bases to offshore oil and gas drilling and production operations.
These financial statements have been prepared on a going concern basis, which the directors believe to be appropriate based on the disclosures made in note 2. 

Business review
 
The company primarily operates in UK and Norwegian oil and gas markets in the North Sea and so demand for services is linked to the activity in the sector which is primarily driven by the market price for such commodities.  The oil price started the year at c $79/bbl and ended the year at $74 /bbl, however during the year there were spikes to $93/bbl in April and dips to $70/bbl.  This relatively steady price assists in creating confidence in the future direction of pricing and subsequent demand; however all parties understand the effect of the Ukraine conflict and Russian sanctions on oil supply and the price strengthening this brought.
The offshore vessel services market improved markedly through 2024. The UK saw £6 billion of investment in 2024 a marked increase for both exploration and development drilling in the North Sea. During 2024 vessel utilization increased and, subsequently, day rates began to climb with Charterers looking to fix vessels on term contracts rather than servicing their requirements from the spot market.  2024 also saw an increase in offshore renewable activities. Tidewater remains in a good position to take advantage of these opportunities and had vessels working in France on two major projects during this period.
Throughout the year, the company’s subsidiaries have continued with best efforts to reduce vessel operating costs where possible whilst still providing a high quality, safe service.

Future outlook
 
The directors intend to seek and obtain new contracts in the offshore and renewables sector and elsewhere within the marine industry whilst maintaining a high level of service provision to existing clients.
As mentioned above, we have seen an improvement in the market throughout 2024. The activity that is forecast for 2025 and beyond, as well as consolidation amongst Vessel Owners, should result in continued improvement for the OSV market. There remains a lack of new build vessels either under construction or on the market and this situation is expected to continue over the next 2 to 5 years. This is expected to further stimulate the market as older tonnage becomes less attractive to potential charterers.
In summary, the board is of the opinion that the long term outlook for the company is positive.
For the fiscal year 2025, the Company will have access to funding, if required, from the ultimate parent, Tidewater Inc. . 
Due to this fact, the Directors are of the opinion that the going concern assessment of GulfMark North Sea Limited and other UK entities is not in doubt.

STRATEGIC REPORT (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2024

DIRECTORS' RESPONSIBILITIES STATEMENT
FOR THE YEAR ENDED 31 DECEMBER 2024

The directors are responsible for preparing the Strategic report, the Directors' report and the financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland'. Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of the company for that period.

 In preparing these financial statements, the directors are required to:

select suitable accounting policies for the company's financial statements and then apply them consistently;

make judgements and accounting estimates that are reasonable and prudent;

state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements;

prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the company's transactions and disclose with reasonable accuracy at any time the financial position of the company and to enable them to ensure that the financial statements comply with the Companies Act 2006They are also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF GULFMARK NORTH SEA LIMITED
 

Opinion


We have audited the financial statements of Gulfmark North Sea Limited (the 'company') for the year ended 31 December 2024, which comprise the Profit and loss account, the Balance sheet, the Statement of changes in equity and the related notes, including a summary of significant accounting policiesThe financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice).


In our opinion the financial statements:


give a true and fair view of the state of the company's affairs as at 31 December 2024 and of its loss for the year then ended;
have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
have been prepared in accordance with the requirements of the Companies Act 2006.


Basis for opinion


We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the United Kingdom, including the Financial Reporting Council's Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.


Conclusions relating to going concern


In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.


Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.


Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.


Other information


The other information comprises the information included in the Annual Report other than the financial statements and our Auditors' report thereon. The directors are responsible for the other information contained within the Annual ReportOur opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.


We have nothing to report in this regard.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF GULFMARK NORTH SEA LIMITED (CONTINUED)

Opinion on other matters prescribed by the Companies Act 2006
 

In our opinion, based on the work undertaken in the course of the audit:


the information given in the Strategic report and the Directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and
the Strategic report and the Directors' report have been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic report or the Directors' report.


We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:


adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
the financial statements are not in agreement with the accounting records and returns; or
certain disclosures of directors' remuneration specified by law are not made; or
we have not received all the information and explanations we require for our audit.


Responsibilities of directors
 

As explained more fully in the Directors' responsibilities statement set out on page 4, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.


In preparing the financial statements, the directors are responsible for assessing the company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the company or to cease operations, or have no realistic alternative but to do so.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF GULFMARK NORTH SEA LIMITED (CONTINUED)

Auditors' responsibilities for the audit of the financial statements
 

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an Auditors' report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.


Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

We obtained an understanding of the legal and regulatory frameworks within which the company operates, focusing on those laws and regulations that have a direct effect on the determination of material amounts and disclosures in the financial statements.  

The laws and regulations we considered in this context were the Companies Act 2006  and UK Taxation legislation.

We identified the greatest risk of material impact on the financial statements from irregularities including fraud to be: 
Management override of controls to manipulate the company’s key performance indicators to meet targets;
Management judgement applied in calculating provisions; and
Compliance with relevant laws and regulations which directly impact the financial statements and those that the company needs to comply with for the purpose of trading. 

Our audit procedures to respond to these risks included: 

Testing of journal entries and other adjustments for appropriateness; 
Evaluating the business rationale of significant transactions outside the normal course of business;
Reviewing judgements made by management in their calculation of accounting estimates for potential management bias; 
Enquiries of management about litigation and claims and inspection of relevant correspondence; and
Reviewing legal and professional fees to identify indications of actual or potential litigation, claims and any non-compliance with laws and regulations. 

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance.  The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation. 


A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditors' report.

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the Companies Act 2006.

The preparation of financial statements in compliance with FRS 102 requires the use of certain critical accounting estimates. It also requires management to exercise judgement in applying the company's accounting policies.

All amounts in the financial statements have been rounded to the nearest £1,000.

The following principal accounting policies have been applied:

 

Financial Reporting Standard 102 - reduced disclosure exemptions

The company has taken advantage of the following disclosure exemptions in preparing these financial statements, as permitted by the FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland":
the requirements of Section 7 Statement of Cash Flows;
the requirements of Section 3 Financial Statement Presentation paragraph 3.17(d);
the requirements of Section 11 Financial Instruments paragraphs 11.42, 11.44 to 11.45, 11.47, 11.48(a)(iii), 11.48(a)(iv), 11.48(b) and 11.48(c);

2.Accounting policies (continued)

 
2.2

Going concern

These financial statements have been prepared on a going concern basis, which the directors believe to be appropriate for the following reasons:
The directors, having made due and careful enquiry, are of the opinion that the company has adequate working capital to execute its operations over the next 12 months. The directors, therefore, have made an informed judgement, at the time of approving the financial statements, that there is a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future.
As a result, the directors have continued to adopt the going concern basis of accounting in preparing the annual financial statements.

 
2.3

Foreign currency translation

Functional and presentation currency

The company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Profit and loss account within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

 
2.4

Pensions

The Company contributes to a defined contribution pension plan for its employees. A defined contribution plan is a pension plan under which the company pays fixed contributions into a separate entity. Once the contributions have been paid the company has no further payment obligations.
The contributions are recognised as an expense in the Statement of Comprehensive Income when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the company in independently administered funds.

2.5

Share based payments

Where share options are awarded to employees, the fair value of the options at the date of grant is charged to profit or loss over the vesting period. Non-market vesting conditions are taken into account by adjusting the number of equity instruments expected to vest at each balance sheet date so that, ultimately, the cumulative amount recognised over the vesting period is based on the number of options that eventually vest. Market vesting conditions are factored into the fair value of the options granted. The cumulative expense is not adjusted for failure to achieve a market vesting condition.
The fair value of the award also takes into account non-vesting conditions. These are either factors beyond the control of either party (such as a target based on an index) or factors which are within the control of one or other of the parties (such as the company keeping the scheme open or the employee maintaining any contributions required by the scheme).
Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modification, is also charged to profit or loss over the remaining vesting period.
Where equity instruments are granted to persons other than employees, profit or loss is charged with fair value of goods and services received.

 
2.6

Taxation

Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the company operates and generates income.

 
2.7

Valuation of investments

Investments in subsidiaries are measured at cost less accumulated impairment. Where merger relief is applicable, the cost of the investment in a subsidiary undertaking is measured at the nominal value of the shares issued together with the fair value of any additional consideration paid.

 
2.8

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

2.9

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

 
2.10

Financial instruments

The company has elected to apply the provisions of Section 11 “Basic Financial Instruments” of FRS 102 to all of its financial instruments.

The company has elected to apply the recognition and measurement provisions of IFRS 9 Financial Instruments (as adopted by the UK Endorsement Board) with the disclosure requirements of Sections 11 and 12 and the other presentation requirements of FRS 102.

Financial instruments are recognised in the company's Balance sheet when the company becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets

Basic financial assets, which include trade and other receivables, cash and bank balances, are initially measured at their transaction price including transaction costs and are subsequently carried at their amortised cost using the effective interest method, less any provision for impairment, unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest.

Discounting is omitted where the effect of discounting is immaterial. The company's cash and cash equivalents, trade and most other receivables due with the operating cycle fall into this category of financial instruments.

Other financial assets

Other financial assets, which includes investments in equity instruments which are not classified as subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the recognised transaction price. Such assets are subsequently measured at fair value with the changes in fair value being recognised in the profit or loss. Where other financial assets are not publicly traded, hence their fair value cannot be measured reliably, they are measured at cost less impairment.

Impairment of financial assets

Financial assets are assessed for indicators of impairment at each reporting date. 

Financial assets are impaired when events, subsequent to their initial recognition, indicate the estimated future cash flows derived from the financial asset(s) have been adversely impacted. The impairment loss will be the difference between the current carrying amount and the present value of the future cash flows at the asset(s) original effective interest rate.

If there is a favourable change in relation to the events surrounding the impairment loss then the impairment can be reviewed for possible reversal. The reversal will not cause the current carrying amount to exceed the original carrying amount had the impairment not been recognised. The impairment reversal is recognised in the profit or loss.

2.10
Financial instruments (continued)

Financial liabilities

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instruments any contract that evidences a residual interest in the assets of the company after the deduction of all its liabilities.

Basic financial liabilities, which include trade and other payables, bank loans and other loans are initially measured at their transaction price after transaction costs. When this constitutes a financing transaction, whereby the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Discounting is omitted where the effect of discounting is immaterial.

Debt instruments are subsequently carried at their amortised cost using the effective interest rate method.

Trade payables are obligations to pay for goods and services that have been acquired in the ordinary course of business from suppliers. Trade payables are classified as current liabilities if the payment is due within one year. If not, they represent non-current liabilities. Trade payables are initially recognised at their transaction price and subsequently are measured at amortised cost using the effective interest method. Discounting is omitted where the effect of discounting is immaterial.

Other financial instruments

Derivatives, including forward exchange contracts, futures contracts and interest rate swaps, are not classified as basic financial instruments. These are initially recognised at fair value on the date the derivative contract is entered into, with costs being charged to the profit or loss. They are subsequently measured at fair value with changes in the profit or loss.

Debt instruments that do not meet the conditions as set out in FRS 102 paragraph 11.9 are subsequently measured at fair value through the profit or loss. This recognition and measurement would also apply to financial instruments where the performance is evaluated on a fair value basis as with a documented risk management or investment strategy.

Derecognition of financial instruments

Derecognition of financial assets

Financial assets are derecognised when their contractual right to future cash flow expire, or are settled, or when the company transfers the asset and substantially all the risks and rewards of ownership to another party. If significant risks and rewards of ownership are retained after the transfer to another party, then the company will continue to recognise the value of the portion of the risks and rewards retained.

Derecognition of financial liabilities

Financial liabilities are derecognised when the company's contractual obligations expire or are discharged or cancelled.
