Description of Business

The Board of Directors of Siem Offshore Inc. present their report for the year ended 31 December 2007 together with the financial statements for the year. The financial statements and related notes will be laid before the shareholders at the Annual General Meeting to be held 8 July 2008.

The year of 2007 was profitable with further expansion of the Company’s business. The operating revenue and result increased significantly as several new vessels were delivered and put into operation. The Company’s capital base was increased through the issue of new shares and from retained earnings. Further commitments were entered into for investments in highly sophisticated support vessels of modern design. The Company’s range of services will continue to increase as these vessels are delivered from yards during the coming years. The work force increased by 33 employees during the year and the Company will continue to recruit skilled offshore and onshore personnel in line with the scheduled increase in activity.

The Board of Directors thank the shareholders for their support and the employees for their contributions and achievements.

Main events in 2007

The Company took delivery of two mid-size Platform Supply Vessels (“PSV”) of VS 470 mk II design and one Multipurpose Field- and ROV Support Vessel (“MRSV”) of MT 6016L design from Norwegian yards.

Options for the construction of six additional Anchor-Handling, Tug, Supply (“AHTS”) vessels of VS 491 design at a Norwegian yard were exercised for delivery during 2010. Two of the shipbuilding contracts for the AHTS vessels were sold to Singa Star Pte Ltd and its subsidiaries (“Singa Star”) as part of a long-term cooperation agreement described below. The Company also acquired a 1999-built large-size PSV of MT 6000 design and a shipbuilding contract for a mid-size PSV of MT6009 design, to be delivered from a Norwegian yard in first quarter 2009.

The one remaining standby vessel and one crew boat operated in Brazil were sold.

Three of the mid-size PSVs were chartered out for a period of three years each. One large-size PSV was converted to a cable-lay vessel for a three-year charter. A five-year charter was entered into for the second MRSV to be delivered in second quarter 2008.

The equity was increased by approximately NOK 1.3 billion through the issue of 85,972,966 new ordinary shares. 55,972,966 new shares were issued by way of a rights issue at NOK 13.00 per share in June and 30,000,000 new shares issued at NOK 18.12 per share in December by way of a private placement to Singa Star.

The Company entered into an agreement for a long-term cooperation with the unrelated Singapore-based private company, Singa Star, whereby Siem Offshore exercised the option for the construction of two AHTS vessels and transferred the shipbuilding contracts for such vessels to Singa Star. Singa Star has granted an option to Siem Offshore to buy back the second shipbuilding contract. Siem Offshore will establish a pool for its 10 AHTS vessels under construction for Siem Offshore and the two additional vessels transferred to Singa Star. Siem Offshore will become the commercial manager of the pool and conduct the shipbuilding supervision and the technical management for the two vessels.

The solutions based on the Siem WIS technology are being introduced to the managed pressure drilling (“MPD”) market worldwide. The market response supports the Company’s belief that the technology and solutions may solve common challenges within the emerging MPD area. A qualification test of the prototype of the constant circulation device, the Siem WIS CircSub, is expected to be performed at a test well during second quarter 2008.

BOARD OF DIRECTORS’ REPORT

Subsequent Events

In January 2008, the Company, through its 51%-owned subsidiary Siem Meling Offshore DA, entered into an agreement to acquire a shipbuilding contract for a large-size PSV of VS 485 design. The contract price is approximately NOK 315 million and the vessel is scheduled for delivery in first quarter 2009 from a Norwegian yard.

Also in January, Siem Consub SA, a 100%-owned subsidiary, entered into an agreement with Petrobras, Brazil to build two Fast Supply Vessels of GPA 150 design for 8 years plus 8 years time charter contracts. The accumulated contract value for the two vessels is approximately USD 45 million for the firm period and both vessels are scheduled to be delivered from a Brazilian shipyard and commence operation in the first quarter of 2010.

Financial Performance

The consolidated financial statements for Siem Offshore are prepared in accordance with International Financial Reporting Standards (IFRS) as adopted by the European Union. Based on the estimated future earnings and operating expenses and the present financing, the financial statements have been prepared under the going-concern assumption.

In 2007, the Company recorded revenues of USD 159 million (2006: USD 74 million), net profit attributable to the shareholders of USD 98 million (2006: USD 45 million) and USD 0.50 earnings per share (2006: USD 0.28 per share).

The net profit for 2007 includes realised and unrealised currency gain of USD 39.6 million arising from the revaluation to market of open currency exchange contracts during 2007. These currency exchange contracts have been entered into to cover the NOK commitment in relation to the vessels under construction at Norwegian yards.

Prior to ordering vessels from Norwegian yards, the Company applied for fixed 12-year interest rate options (“CIRR”) related to the long-term financing of such vessels. The Company was granted such options by the Norwegian Export Credit Agency. During 2007, the Company sold the right to exercise such options to a first class international bank (the “Bank”) in consideration for an up-front payment of USD 23.5 million. If the options for the fixed interest rates are exercised by the Bank, then the Company will draw up to USD 950 million from the Norwegian Export Credit Agency. Any long-term loans drawn from the Norwegian Export Credit Agency will be placed as corresponding deposits in the Bank as financial security for any loans drawn. The up-front payment of USD 23.5 million was recorded as a gain during second and third quarter of 2007 in accordance with advice received at that time. After further discussions with our auditors, it was determined that the recognition of the gain, related to each relevant vessel, shall be recorded over the term of any drawn loans, or in whole if the relevant loan is not drawn. Accordingly, USD 0.1 million of the total up-front payment is recorded in the 2007 profit and loss account (see also note 10).

The Board proposes that the net profit of USD 98 million for 2007 be carried forward in the balance sheet as retained earnings and that no dividend be paid for 2007. As of 31 December 2007, retained earnings were USD 124 million.

Balance Sheet and Financing

Shareholders’ equity was USD 462 million, or USD 1.82 per share, based on 253,891,866 issued and outstanding shares. The book equity ratio was 53%.

The cash position at year end was USD 188 million. The gross interest-bearing debt was USD 364 million. Such debt includes the equivalent of NOK 269 million drawn under a Term Loan Facility in the majority-owned company, Siem Meling Offshore DA. The Company has USD 67 million available in way of undrawn borrowings under loan and working capital facilities per year-end 2007.

Future yard instalments for vessels under construction totalled NOK 6.4 billion (USD 1.2 billion) at the end of 2007. Such yard instalments fall due in 2008 with NOK 1.4 billion (USD 252 million), 2009 with NOK 2.9 billion (USD 536 million), and 2010 with NOK 2.1 billion (USD 393 million).

Shareholder Information

As of 31 December 2007, Siem Offshore had 2,657 shareholders. The total number of issued and outstanding shares in Siem Offshore was 253,891,866 shares. The largest shareholder, Siem Industries Inc., held 34% of the shares. Approximately 48% of the outstanding shares were owned by Norwegian shareholders at year-end 2007.

The Board holds authorisation to issue 81,108,134 new shares.

Corporate Governance

As a company incorporated in the Cayman Islands, Siem Offshore is subject to Cayman Islands laws and regulations. Cayman Islands’ corporate law is to a great extent based on English law. In addition, certain aspects of Norwegian Securities law apply to the Company due to its listing on the Oslo Stock Exchange.

The Company endeavours to maintain high standards of corporate governance and is committed to ensuring that all shareholders of the Company are treated equally. The Board monitors the performance of management through regular meetings and reporting.

All the issued shares in Siem Offshore are freely tradable and carry the same rights with no restrictions on voting. The 2008 Annual General Meeting of the Company will be held at the George Town office of the Company on 8 July 2008. Shareholders can attend or be represented by proxy.

A revised Norwegian Code of Practice for Corporate Governance was published on 4 December 2007, which is effective 1 January 2008. The Company has provided an annual statement relating to their compliance with the code dated 28 November 2006 (see separate section page 41).

Financial Risks

Interest and currency rates Risk

The majority of the company’s assets are denominated in NOK. Future yard instalments and most of the vessels operating costs are nominated in NOK. Overhead expenses are primarily in USD, NOK and BRL.

Management monitors these risks and enters into forward currency contracts for hedging purposes from time to time to reduce the exposure to currency fluctuations. Siem Offshore has entered into such currency exchange contracts in order to fix the NOK commitment in relation to the vessels under construction at Norwegian yards. As of 31 December 2007, the Company has sold forward approximately USD 186 million, equivalent to NOK 1.1 billion, of the total future yard commitments of NOK 6.4 billion at average exchange rate USD/NOK 5.9085.

All interest-bearing loans are based on floating interest rate, except the loan from BNDES in Brazil and the loans drawn from the Norwegian Export Credit Agency in relation to the sale of the interest rate options received from Eksportfinans.

Liquidity Risk

The Company is financed by debt and equity. If the Company fails to repay or refinance its loan facilities, additional equity financing may be required. There can be no assurance that the Company will be able to repay its debts or extend their re-payment schedule through re-financing of the loan agreements or not experience net cash flow shortfalls exceeding the Company’s available funding sources or to comply with a minimum cash requirements, nor can there be any assurance that the Company will be able to raise new equity, or arrange new borrowing facilities, on favourable terms and in amounts necessary to conduct its ongoing and future operations, should this be required.

Yard Risk

The process for construction of new vessels is associated with numerous risks. Among the most critical risk factors in relations to such construction is the risk of not receiving the vessels on time, at budget and with agreed specifications. In addition, there is the risk of the different yards experiencing financial or operational difficulties resulting in bankruptcy or otherwise adversely affecting the construction process. The Company has obtained certain guarantees of financial compensation including refund guarantees in case of delays and non-delivery, and it has the right to cancel contracts if delivery of vessels is significantly delayed. However, no assurance can be given that all risks have been fully covered.

Delays and non-delivery of the vessels under construction is likely result in a loss of income for the Company, and could also possibly lead to breach of contract in respect of contracts entered into between the Company and third parties concerning employment of vessels.

Credit risk

The Board considers that the credit risk is diversified as the Company is not significantly exposed to one individual customer or contract as at 31 December 2007.

8

Safety and Environmental Issues

The core values of Siem Offshore include the strict observance of laws, best practices and acting responsibly towards the environment. The Company is in compliance with environmental regulations imposed by relevant national authorities and international conventions. There is always a risk that bunkers and oils onboard our vessels may cause pollution to the environment and that collision and serious breakdowns of the vessels may occur. However, regarding the operational activities and vessels fully owned by Siem Offshore, the Company has devised systems with the aim to prevent such incidents and to mitigate the damages should they occur. Siem Offshore did not experience material spills of fuel during 2007 and caused no environmental harm. One of our core values is that the Company shall not compromise on safeguarding the individual life, health or safety. There have been no serious accidents involving personnel in 2007 relating to the operation by the Company.

Management and Organization

The number of employees at the end of 2007 was 618. The Company offers its employees a sound working environment with possibilities for professional development where individuals are treated equally and without discrimination.

Outlook

The supply and demand for the PSV spot market remained generally in balance during 2007. The demand declined at the end of fourth quarter and has remained at a relative lower level during first quarter 2008. Such decline in demand is believed to be seasonal and has often been experienced at this time of the year. The spot market day rates have been volatile during first quarter 2008. Some vessels have secured medium-term fixtures and the level of activity has increased. There is an encouraging level of global interest in medium and long term employment of PSVs, in particular for mid- and large-size vessels for project-related work.

We continue to feel confident about the specification and demand for the AHTS vessels we have under construction.

The high number of vessels under construction is a concern and additional yard orders may lead to an oversupply of support vessels for the offshore industry. Replacement of older and smaller vessels will however, increase the demand for the company’s type of vessels.

Note 1 - Accounting Principles

Basis of preparation

Siem Offshore Group ( “ The Company”) prepares consolidated financial statements in accordance with International Financial Reporting Standards(“IFRS”), and International Financial Reporting Interpretations Committee (“IFRIC”), endorsed by the European Union and the regulations of Oslo Stock Exchange. As of 31 December 2007, there were no differences between these standards and International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board, and the policies adopted by the Company. The consolidated financial statements have been prepared under the historical cost convention, as modified by fair value of non-current assets held for sale, and financial assets, including derivative instruments at fair value through profit or loss. The financial statements have been prepared under the assumption that the Company is a going concern. A summary of the principal accounting policies applied in the preparation of these consolidated financial statements is set out below.

All figures are in USD thousands unless otherwise clearly stated. USD is the functional currency for the Company.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Company’s accounting policies. The areas involving a higher degree of judgement or complexity or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed under “Critical accounting estimates and judgements” presented below.

Accounting policies

The following new standards, amendments to standards and interpretations are mandatory for the financial year ending 31 December 2007.

• IAS1(Amendment),‘Presentationoffinancialstatements’–Capitaldisclosures.Theamendmentrequiresadditionaldisclosurestoenable users of the financial statements to evaluate the Company’s objectives, policies and processes for managing capital.

• IFRS7,‘Financialinstruments:Disclosures’,andthecomplementaryamendmenttoIAS1,‘Presentationoffinancialstatements–Capital disclosures’, introduces new disclosures relating to financial instruments and does not have any impact on the classification and valuation of the Company’s financial instruments, or the disclosures relating to taxation and trade and other payables.

• IFRIC8,‘ScopeofIFRS2’,requiresconsiderationoftransactionsinvolvingtheissuanceofequityinstruments,wheretheidentifiable consideration received is less than the fair value of the equity instruments issued in order to establish whether or not they fall within the scope of IFRS 2. This standard does not have any impact on the Company’s financial statements.

• IFRIC10,‘Interimfinancialreportingandimpairment’,prohibitstheimpairmentlossesrecognisedinaninterimperiodongoodwilland investments in equity instruments and in financial assets carried at cost to be reversed at a subsequent balance sheet date. This standard does not have any impact on the Company’s financial statements.

The following standards, amendments and interpretations to published standards are mandatory for accounting periods beginning on or after 1 January 2007 but they are not relevant to the company’s operations:

• RevisedguidanceonimplementingIFRS4,‘Insurancecontracts’;

• IFRIC7,‘ApplyingtherestatementapproachunderIAS29,Financialreportinginhyper-inflationaryeconomies’;and

• IFRIC9,‘Re-assessmentofembeddedderivatives’.

The following new standards, amendments to standards and interpretations have been issued but are not effective for 2007 and have not been early adopted:

• IAS23(Amendment),‘Borrowingcosts’(effectivefrom1January2009).Itrequiresanentitytocapitaliseborrowingcostsdirectly attributable to the acquisition, construction or production of a qualifying asset (one that takes a substantial period of time to get ready for use or sale) as part of the cost of that asset. The option of immediately expensing those borrowing costs will be removed. The Company will apply to IAS 23 (Amended) from 1 January 2009.

The group will apply IFRS 8 from 1 January 2009. The expected impact is still being assessed in detail by management, but it appears likely that the number of reportable segments, as well as the manner in which the segments are reported, will change in a manner that is consistent with the internal reporting provided to the chief operating decision-maker.

IFRIC 14 provides guidance on assessing the limit in IAS 19 on the amount of the surplus that can be recognised as an asset. It also explains how the pension asset or liability may be affected by a statutory or contractual minimum funding requirement. The Company will apply IFRIC 14 from 1 January 2008, but it is not expected to have any impact on the Company’s accounts.

The following interpretations to existing standards have been published and are mandatory for the group’s accounting periods beginning on or after 1 January 2008 or later periods but are not relevant for the Company’s operations:

• IFRIC12,‘Serviceconcessionarrangements’(effectivefrom1January2008).IFRIC12appliestocontractualarrangementswherebya private sector operator participates in the development, financing, operation and maintenance of infrastructure for public sector services. IFRIC 12 is not relevant to the company’s operations because none of the Company’s subsidiaries provide for public sector services.

IFRIC 13 is not relevant to the Company’s operations because none of the Company’s subsidiaries operate any loyalty programmes.

Consolidation

(a) Subsidiaries

Subsidiaries are all entities (including special purpose entities) over which the Company has the power to govern the financial and operating policies generally accompanying a shareholding of more than one half of the voting rights. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Company controls another entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are de-consolidated from the date that control ceases.

The purchase method of accounting is used to account for the acquisition of subsidiaries by the Company. The cost of an acquisition is measured as the fair value of the assets given, equity instruments issued and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date, irrespective of the extent of any minority interest. The excess of the cost of acquisition over the fair value of the Company’s share of the identifiable net assets acquired is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognised directly in the income statement. Identifiable assets consist of tangible assets and intangible assets other than goodwill.

Inter-company transactions, inter-company balances and unrealized profit between group companies have been eliminated. Unrealized loss is eliminated, but considered an impairment indicator of the asset transferred.

The minority interests in equity and in net results are reported separately in the consolidated financial statements.

(b) Associated companies

Associates are all entities over which the Company has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting and are initially recognised at cost. The Company’s investment in associates includes goodwill (net of any accumulated impairment loss) identified on acquisition. The share of earnings recorded in the consolidated financial statements are based on the after tax earnings of the associates. In the income statement, the share of earnings from associates is shown as a financing item.

16

The Company’s share of its associates’ post-acquisition profits or losses is recognised in the income statement and its share of post-acquisition movements in reserves is recognised in reserves. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. When the Company’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Company does not recognise further losses unless it has incurred obligations or made payments on behalf of the associate.

Unrealised gains on transactions between the Company and its associates are eliminated to the extent of the Company’s interest in the associates. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been reconciled where necessary to ensure consistency with the policies adopted by the Company.

Classification of items in the financial statements

Assets designated for long-term ownership or use and receivables falling due later than one year after drawdown have been recorded as long-term assets. Other assets are classified as current assets. Receivables are stated at par value less provision for doubtful accounts. Liabilities which fall due later than one year after the end of the accounting year are posted as long-term liabilities. Other liabilities are classified as current liabilities.

The Company’s share of its associates’ post-acquisition profits or losses is recognised in the income statement and its share of post-acquisition movements in reserves is recognised in reserves. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. When the Company’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Company does not recognise further losses unless it has incurred obligations or made payments on behalf of the associate.

Unrealised gains on transactions between the Company and its associates are eliminated to the extent of the Company’s interest in the associates. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been reconciled where necessary to ensure consistency with the policies adopted by the Company.

Segment reporting

A business segment is a group of assets and operations engaged in providing products or services that are subject to risks and returns that are different from those of other business segments. A geographical segment is engaged in providing products or services within a particular economic environment that are subject to risks and return that are different from those of segments operating in other economic environments.

The Company is organized into five different divisions, named Supply/Crew fleet, MRSV, AHTS, Combat Management Systems, and Other, in which the Company operates.

Foreign currency translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Company’s entities are measured using the currency of the primary economic environment in whichtheentityoperates(the‘functionalcurrency’).TheconsolidatedfinancialstatementsarepresentedinUSD,whichistheCompany’sfunctionaland presentation currency.

All amounts in these financial statements are in USD 1,000 unless otherwise stated.

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement.

The exchange rate used throughout the Company at the balance sheet date, compared to the US dollar, were as follows:

Average 31.12.2007

NOK (Norwegian Krones): 5,8502 5,4308

EUR (Euros): 1,3741 1,4620

GBP (Pound Sterling): 2,0024 1,9909

REAS (Brazilian Reals): 1,9460 1,7713

17

(c) Group companies

The results and financial position of all the group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

(i)assetsandliabilitiesforeachbalancesheetpresentedaretranslatedattheclosingrateatthedateofthatbalancesheet;

(ii) income and expenses for each income statement are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the dates of the transactions);and

(iii) all resulting exchange differences are recognised as a separate component of equity.

In consolidation, exchange differences arising from the translation of the net investment in foreign operations and from borrowings are taken to shareholders’ equity. When a foreign operation is sold, exchange differences that were recorded in equity are recognised in the income statement as part of the gain or loss on sale.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing rate.

Fixed assets and maintenance costs

Vessels are measured in the consolidated balance sheet at cost less accumulated depreciation and impairment loss. Depreciation is on a straight-line basis and determined by an estimate of the remaining useful economic life of the asset. Estimated scrap value is taken into account and reassessed at 31 December each year. The vessels presently owned by Siem Offshore are considered to have an economic life of 30 years. Other fixed assets are depreciated on a straight-line basis over the anticipated useful life.

Each part of a fixed asset that is significant to the total cost of the asset is separately identified and depreciated over that component’s useful lifetime. Components with similar useful lives will be included in one component. The Company has identified 5 significant components relating to their different types of vessels.

In accordance with IAS 16 and the cost model, dry-dock costs are considered a separate component of the ships’ cost at purchase with a different pattern of benefits and, therefore, need to be amortised separately.

Day-to-day maintenance costs are charged to the income statement during the financial period in which they are incurred. The cost of major renovations and periodic maintenance of vessels is capitalised and depreciated over the useful lifetime of the parts replaced. The useful life of the regular vessels docking expenses will normally be the period until next docking.

The residual value and expected useful lifetime assumptions of fixed-assets are reviewed at each balance sheet date and, where they differ significantly from previous estimates, depreciation charges are changed accordingly.

Gains and losses on disposals are determined by comparing the disposal proceeds with the carrying amount and are included in operating profit.

Newbuilding contracts

Instalments on newbuilding contracts are posted in the balance sheet as non-current assets. Costs related to the on-site supervision and other pre-delivery construction costs are capitalised per vessel.

Impairment of fixed assets

Each year non-current assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The asset’s cash generating ability either through use or sale is reviewed and compared to the asset’s carrying amount in the balance sheet. If the carrying amount is higher, the difference must be written off as an impairment loss. Fair value reduced by estimated sales costs is the amount achievable on sale to an independent third party. The recoverable amount is established individually for all assets. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time and the risk specific to the asset that is considered impaired.

A previously recognised impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. Reversal of previously recognised impairment is limited to the amount the carrying value of the asset would have been had the initial impairment charge not taken place.

Dry-dock costs

Dry-docking costs are capitalised and amortised over the period until the next scheduled dry-dock ranging from 2 to 3 years.

The unamortised value of the previous dry-docking is decomposed from the purchase price when ships are acquired and amortized as described above.

18

Intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortisation and any accumulated impairment losses. Internally generated intangible assets, excluding capitalised development costs, are not capitalised and expenditure is charged against profits in the year in which the expenditure is incurred. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets with finite lives are amortised over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortisation period and the amortisation method for an intangible asset with a finite useful life are reviewed at least at each financial year-end. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset is accounted for by changing the amortisation period or method, as appropriate, and treated as a change in accounting estimate. The amortisation expense on intangible assets with finite lives is recognised in the income statement in the expense category consistent with the function of the intangible asset.

Intangible assets within indefinite useful lives are tested for impairment annually either individually or at the cash-generating unit level. Such intangibles are not amortised. The useful life of an intangible asset with an indefinite life is reviewed annually to determine whether indefinite life assessment continues to be supportable. If not, the change in the useful life assessment from indefinite to finite is made on a prospective basis.

Financial assets

The Company classifies its financial assets in the following categories: Financial assets at fair value, Loans and receivables, and Available for sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition and re-evaluates this designation at every reporting date.

(a) Financial assets at fair value

This category has two sub-categories: financial assets held for trading and those designated at fair value through profit or loss at inception. A financial asset is classified in this category if acquired principally for the purpose of selling in the short term or if so designated by management. Derivatives are also categorised as held for trading unless they are designated as hedges. Assets in this category are classified as current assets if they are either held for trading or are expected to be realised within 12 months of the balance sheet date.

(b) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for maturities greater than 12 months after the balance sheet date. These are classified as non-current assets. Loans and receivables are classified as ”trade and other receivables” in the balance sheet.

(c) Available for sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless management intends to dispose of the investment within 12 months of the balance sheet date.

Purchases and sales of financial assets are recognised on the trade-date, the date on which the Company commits to purchase or sell the asset. Investments are initially recognised at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognised at fair value and transaction costs are expensed in the income statement. Financial assets are de-recognised when the rights to receive cash flows from the investments have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are carried at amortised cost using the effective interest method.

Gains or losses arising from changes in the fair value of the “financial assets at fair value through profit or loss” category are presented in the income statement within net gains (losses) in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognised in the income statement as part of other income when the Company’s right to receive payment is established.

The Company assesses at each balance sheet date whether there is objective evidence that a financial asset or a group of financial assets is impaired.

Inventories

Lubricating oil and bunkers inventories are valued at the lower of historical cost and market value applying the FIFO (first-in, first-out) principle. The Company makes inventory provisions based on an assessment of excess and obsolete inventories.

Cash and cash equivalents

Cash and cash equivalents includes cash in hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities on the balance sheet.

Accounts receivable

Accounts receivable are reported at amortised cost. The interest factor is ignored if insignificant. In the case of objective evidence of a fall in value, the difference between reported value and the present value of the future cash flow is reported as a loss.

19

Share capital

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction, net of tax, from the proceeds. When the Company purchases its own shares, the consideration paid, including any directly attributable incremental costs (net of income taxes), is deducted from equity attributable to the Company’s equity holders until the shares are cancelled.

Borrowings

Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost. Any difference between the proceeds (net of transaction costs) and the redemption value is recognised in the income statement over the period of the borrowings using the effective interest method.

Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.

Taxation

Tax expense/benefit includes current taxes and the change in deferred taxes. Deferred income tax is provided for all temporary differences between the book value and the tax basis of assets and liabilities and for tax losses carried forward. Deferred tax assets made probable through prospective earnings that can be utilized against the tax reducing temporary differences are recognized as intangible assets. Deferred tax asset and deferred tax liability are recognised independently of when the differences will be reversed and, as a rule, at nominal value. Deferred tax asset and tax liability are measured on the basis of estimated future tax rate.

Parts of the Company’s activities within the Norwegian subsidiaries are structured within the regulations for the Norwegian Tonnage Tax System for shipping companies. The tax cost and deferred tax liability for subsidiaries its organised under this tax regime depend on the subsidiaries dividend policy and future estimated profits.

Pension costs and obligations

The net present value of the future obligations of Siem Offshore’s pension plans is calculated based on certain estimates with regards to interest rates for future salary adjustments etc. Net pension expenses are posted as salary-related expenses in the profit and loss account. The estimated net obligations are included in provisions in the balance sheet. The effect of changes in estimates and differences between estimated and actual return are recognised only when the accumulated effect exceeds 10% of the larger of the pension fund and the pension obligation. The excess amount is amortised over the remaining service life of the employees.

Siem Offshore has a defined benefit plan for its employees in Norway. A defined benefit plan defines the amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

Contingent liabilities and provisions

Provisions are made for uncertain liabilities that are probable and can be relaiable measured.

Financial derivatives

Siem Offshore enters into derivative instruments, primarily foreign currency contracts, to hedge the foreign currency rates. The criteria for qualifying as a hedge under IFRS are strict. The Company’s foreign currency contracts do not qualify as hedging. The fair market value of these contracts is recorded as a receivable or liability and any change in the valuation is recognized in the profit and loss as operating expenses.

Revenue recognition

The group’s activity is mainly hiring out different kind of offshore support vessels, such as PSVs, MRSVs,AHTSs, standby vessels, and crewboats. In addition, the Company holds interest in two limited liability partnerships, owning one scientific core drilling vessel and one well stimulation vessel respectively. In one of the subsidiaries of the Company, revenues are mainly arisen from income from construction contracts. Revenue comprises the fair value of the consideration received or receivable for the sale of goods and services in the ordinary course of the Company’s activities. Revenue is shown net of value-added tax, withholding tax, returns, rebates and discounts and after eliminated sales within the Company. Revenue is recognised as follows:

Charter rate contracts

Revenue derived from charterhire contracts or other service contracts is recognised in the period that services are rendered at rates established in the relevant contracts. Certain contracts include mobilisation fees payable at the start of the contract. In cases where the fee covers a general upgrade of a rig or equipment which increases the value of the rig or equipment beyond the contract period, the fee is recognised as revenue over the contract period whereas the investment is depreciated over the remaining lifetime of the asset.

In cases where the fee covers specific upgrades or equipment specific to the contract, the mobilisation fees are recognised as revenue over the estimated contract period. The related investment is depreciated over the estimated contract period. In cases where the fee covers specific operating expenses at the start of the contract, the fees are recognised in the same period as the expenses or over the total contract period.

20

Vessels without signed contracts in place at discharge have no revenue before a new contract is signed. Charter-related expenses incurred for vessels in the idle time are expensed. Revenues from time charters and bareboat charters accounted for as operating leases are recognised rateably over the rental periods of such charters as service is performed.

Construction contracts

The Company follows the generally accepted practice of accounting for long-term construction, engineering and project management contracts on the percentage-of-completion basis as costs are incurred. Under this method, revenue and income is recognised as work progresses on the contract. If a contract can be split into subprojects, each subproject is treated separately.

For all contracts, no profit is recognised before the outcome of the contract can be measured reliably and, generally, this will mean no profit is recognised until progress has reached at least 20% of completion. The estimated cost used to determine profit at completion reflects all facts or occurrencesexpectedtoaffectthefinalcostofthecontract;therefore,theentireamountofanyestimatedcontractlossisrecognisedwhenitfirstbecomes evident.

For contracts which satisfy certain criteria, profit is recognised in accordance with the risk profile of the contract as assessed by management instead of being recognised in accordance with the simple percentage of total costs principle. The pattern of revenue recognition for these contracts will depend on individual contract circumstances and terms but, generally, the application of this policy may result in there being a requirement for a larger percentage-of-completion prior to any profit being recognised, the application of variable profit margins at separately identifiable stages of the contract, and the majority of profit being recognised in the later stages of the contract.

For projects that are assumed to result in a loss, the total estimated loss is recognised immediately.

Interest income

Interest income is recognised on a time-proportion basis using the effective interest method. When a receivable is impaired, the Group reduces the carrying amount to its recoverable amount, being the estimated future cash flow discounted at original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loans is recognised using the original effective interest rate.

Dividend income

Dividend income is recognised when the right to receive payment is established.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and are accounted for when estimates are changed. Actual results could differ from such estimates.

Earnings per share

Earnings per share are calculated by dividing the net profit/loss for Siem Offshore by the weighted average number of outstanding shares over the period in question. Diluted earnings per share include the effect of the assumed conversion of potentially dilutive instruments such as stock options. The impact of share equivalents is computed using the treasury stock method for share options.

Cash flow statement

The statement of cash flow is prepared in accordance with the indirect model.

Related party transactions

All transactions, agreements and business activities with related parties are set on arm’s length basis in a manner similar to transactions with third parties.

Events after balance sheet

New information regarding the Company’s standing on balance sheet date is included in the accounts. Events occurring after balance sheet date which do not impact the Company’s standing on the balance sheet date but which have a significant impact on future period are presented in the notes to the accounts.

21

Critical accounting estimates and judgements

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The Company makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.

The preparation of the financial statements in conformity with generally accepted accounting principles under IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and are accounted for when estimates are changed. Actual results could differ from such estimates. The balance sheet value of the Company’s vessels, newbuilding contract included, comprises approximately 80% of the total balance sheet. In the current market for supply vessels, the fair value of the Company’s vessels is significantly higher than the balance sheet value. The Company makes use of the cost model according to IAS 16, and subsequently depreciates non-current assets over their estimated economic life, regardless of the extent to which there has been a genuine increase in value of the Company’s non-current assets. When calculating annual depreciation, the estimated period of use for the vessel and the estimated residual value at the end of the period of use is significant estimates.

Tax legislation is subject to varying interpretation. Refer to Note 9.

Deferred tax liability from acquisition of subsidiaries, relates to acquisition of Rovde Shipping subsidiary, Rovde Supply AS. The Norwegian Government has resolved that a new tonnage tax regime shall be made effective from 1 January 2007 and that the previous deferred tax regime available for ship-owning companies shall end. Ship-owning companies that adopt the new tonnage tax regime, as an alternative to ordinary corporate taxation, must pay any deferred tax in annual instalments during a period of 10 years. 1/3 of such liability can be offset for any qualifying environmental investments in vessels and/or equipment to be made during such 15 year period. The gross deferred tax liability for the Company’s Norwegian subsidiaries at 31 December 2007 was NOK 53 million (USD 9.7 million) and the result for fourth quarter 2007 includes a tax charge of USD 0.7 million in order to reflect the change of tax legislation.

Deferred tax assets are not recognized as intangible assets because it is not made probable through prospective earnings that it can be utilized against the tax reducing temporary differences.

Prior to ordering vessels from Norwegian yards, the Company applied for fixed 12-year interest rate options related to the long-term financing of such vessels. The Company was granted such options by the Norwegian Export Credit Agency. During 2007, the Company sold the right to exercise such options to a first class international bank (the “Bank”) in consideration for an up-front payment of USD 23.5 million. If the options for the fixed interest rates are exercised by the Bank, then the Company will draw up to USD 950 million from the Norwegian Export Credit Agency. Any long-term loans drawn from the Norwegian Export Credit Agency will be placed as corresponding deposits in the Bank as financial security for any loans drawn. Recognition of the gain, related to each relevant vessel, shall be recorded over the term of any drawn loans, or in whole if the relevant loan is not drawn. Accordingly, USD 0.1 million of the total up-front payment is recorded in the 2007 profit and loss account.

NOTE 26 - Financial Risk Management

Lack of historical financial information

Siem Offshore Inc. (the Company) was incorporated in October 2004 and has limited operating history. The historical financial statements included herein are thus limited and may therefore not be useful in estimating the Company’s future financial results. Potential investors are therefore urged to make their own assessment of the Company’s future financial results, by comparing the Company to similar companies with longer operating histories.

Financial leverage

The companies in Siem Offshore Inc. are financed by debt and equity. If the Company fails to repay or refinance its loan facilities, additional equity financing may be required. There can be no assurance that the Company will be able to repay its debts or extend their re-payment schedule through re-financing of the loan agreements or not experience net cash flow shortfalls exceeding the Company’s available funding sources or to comply with a minimum cash requirements, nor can there be any assurance that the Company will be able to raise new equity, or arrange new borrowing facilities, on favourable terms and in amounts necessary to conduct its ongoing and future operations, should this be required.

In the event of insolvency, liquidation or similar event relating to a subsidiary of the Company, all creditors of such subsidiary would be entitled to payment in full out of the assets of such subsidiary before the Company, as a shareholder, would be entitled to any payments. Defaults by, or the insolvency of, a subsidiary of the Company could result in the obligation of the Company to make payments under parent company guarantees issued in favour of such subsidiary.

Interest rates and currency fluctuations

For the Company, USD is the functional and reporting currency. Purchase from sub-contractors and deliveries to customers are to some extent performed in currencies other than USD. The Company is exposed to foreign exchange risk of its subsidiaries, including the development of the Brazilian real. The Shares listed on the Oslo Børs are quoted in NOK. There is a foreign exchange risk associated with conversion from the reporting currency to NOK.

The Company is moreover exposed to changes in interest rates, which may affect the Company’s financial results significantly. Note 26 - Sensitivity

Risks related to possible tax liabilities

The Company will seek to optimise its tax structure to minimise withholding taxes when operating vessels abroad, avoiding double taxation, and minimising corporate tax paid by optimally making use of the shipping taxation rules that applies. It is, however, a challenging task to optimise taxation, and there is always a risk that the Company may end up paying more taxes than the theoretical minimum, which may in turn affect the financial results negatively.

CORPORATE GOVERNANCE

Corporate Governance Policy of Siem Offshore

The principles for corporate governance adopted by the Company is based on the “Norwegian Recommendation for Corporate Governance” issued on the 28th November 2006, which is a revised version of the recommendation issued on the 7th December 2004, and good common sense.

As a Company incorporated in the Cayman Islands, Siem Offshore Inc. is subject to Cayman Island Laws and regulations with respect to corporate governance. Cayman Islands corporate law is to a great extent based on English Law. In addition, due to the Company’s listing on the Oslo Stock Exchange, certain aspects of Norwegian Securities law apply to the Company and there is a requirement to adhere to the Norwegian Code of Practice for Corporate Governance. The Company endeavours to maintain high standards of corporate governance and is committed to ensure that all shareholders of the Company are treated equally and the same information is communicated to all shareholders at the same time.

It is the opinion of the Board of Directors that the Company complies with the Norwegian Code of Practice for Corporate Governance, but would like to comment on the following:

Business

As stated, Siem Offshore Inc. is subject to Cayman Islands laws and regulations which do not require the objects clause of the Companies Memorandum and Articles of Association to be clearly defined. The Company has however adopted clear objectives and strategies for its business.

Siem Offshore aims to grow the company within offshore support vessels, both organically and through combination with other operators, in order to achieve economies of scale and stronger presence in the market.

Siem Offshore aims to become a preferred supplier of marine services to the oil & gas industries based on quality and reliability and provide cost efficient solutions for its customers by understanding their operation and applying technology and experience.

The Company build its business around a motivated workforce with the appropriate technical solutions and creating sustainable value to all shareholders.

Equity and Dividends

The priorities of the use of Company funds are firstly the investment opportunities in the business, secondly the repayment of debt and thirdly the return of capital to the shareholders in form of dividends or share buy-back.

The Board’s mandate to increase the Company’s share capital is limited only to the extent of the authorised share capital of the Company but with pre-emption rights for shareholders and in accordance with the Company’s Memorandum and Articles of Association which comply with Cayman Island law.

Under the Articles of Association, the Board can issue new shares, convertible bonds or warrants at any time within the limits of the authorised capital without the consent of the general meeting but with pre-emption rights for shareholders. A General Meeting has further authorised the Board to issue new shares without pre-emption rights to all shareholders up to a limit of 50% of Siem Offshore’ shares at the time the authorisation was given. The Board holds authorisation from General Meeting 10 July 2007 to issue a further 81,108,134 new shares. The authority gives the Board flexibility to finance investments, acquisitions and other business combinations on short notice through the issue of shares or certain other equity instruments in the Company. Furthermore the Board considers the granting of a new standing authority at the time of holding an Annual General Meeting rather than convening an Extraordinary General Meeting at some future time to be in the best interests of the Company, as this will result in cost savings and more effective time management for both the Company’s senior management and its Shareholders.

Equal Treatment of Shareholders, Freely Tradable Shares and Transactions with Related Parties

The Company is committed to ensuring that all shareholders of the Company are treated equally and all the issued shares in Siem Offshore are freely tradable and carry the same rights with no restrictions on voting.

Siem Industries which owns 33.68% of Siem Offshore is represented by its Chairman Kristian Siem and President Michael Delouche on the Board of Siem Offshore. The Company pays an annual fee to Siem Industries as compensation for directorships, provision of an office and presence in the Cayman Islands, and other services. The fee is adopted by the annual general meeting based on a recommendation from the independent Board Members. Related part transactions are disclosed in the notes to the accounts.

General Meetings

The annual general meeting of the Company will be held at the George Town office of the Company on July 8, 2008 and Shareholders can be present in person or by proxy.

42

Board of Directors

The appointment of a nomination committee is not a requirement under Cayman Islands Law. In the appointment of board of directors, the Board consults with the Company’s major shareholders and ensures that the board is constituted by directors with the necessary expertise and capacity. In addition, there is no requirement under Cayman Islands Law for the Company to establish a corporate assembly.

Siem Industries, the company’s largest shareholder, is represented on the Board through its chairman, Kristian Siem, and its president, Michael Delouche.

The Board of Directors as a group have extensive experience in areas which are important to Siem Offshore, including offshore services, international shipping, ship broking, financing and corporate governance and restructuring.

Work of the Board of Directors

The Board monitors the performance of management through regular meetings and reporting. The Company has a Compensation Committee and an Audit Committee.

Remuneration of Board of Directors

The remuneration of the Board members reflect their experience and is adopted by the annual general meeting based on the recommendation from the Board. The Board members do not have options or profit-based remuneration.

Remuneration of Leading Employees

The Company has a Compensation Committee which reviews and approves the compensation of the CEO and the bonuses to all leading employees. The Articles of Association of the Company permit the board to approve the granting of share options to employees. Currently there are no option programs in force. The remuneration and pension scheme of the CEO is disclosed in the notes to the accounts.

Information and Communication

The Company has a policy of treating all its shareholders equally and keeping them properly updated of significant developments which impact on the Company. It does this through notices to the Oslo Stock Exchange, which are also published on the company’s website (www.siemoffshore.com).

Take-over Situations

The shares in the Company are freely tradable and the Articles of Association of the Company does not hold specific defence mechanisms against take-over situations.

Auditor

The Auditor of the Company is elected at the annual general meeting which also approves its remuneration. The auditor reports on internal controls, risk areas and improvement potential in control systems once a year to the Audit Committee and Chairman. The audit process is planned in detail and the findings of the auditors are discussed with management and potential bigger issues are brought to the attention of the Audit Committee.
