Transocean Proxy Statement and 2010 Annual Report

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
We have not had a change in or disagreement with our accountants within 24 months prior to the date of our most recent
financial statements or in any period subsequent to such date.
Item 9A. Controls and Procedures
Disclosure controls and procedures—We carried out an evaluation, under the supervision and with the participation of
management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and
procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial
Officer concluded that our disclosure controls and procedures, as defined in Exchange Act Rules 13a-15(e) and 15d-15(e), were effective
as of December 31, 2010 and provide reasonable assurance that information required to be disclosed in our reports filed or submitted
under the Exchange Act is (1) accumulated and communicated to our management, including our Chief Executive Officer and our Chief
Financial Officer, to allow timely decisions regarding required disclosure and (2) recorded, processed, summarized and reported within
the time periods specified in the Securities and Exchange Commission’s rules and forms.
Internal controls over financial reporting—There were no changes in these internal controls during the quarter ended
December 31, 2010 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
Other matters—In April 2010, we implemented a new global Enterprise Resource Planning (“ERP”) system, a fully integrated
software environment, designed to optimize and standardize processes in treasury, accounting, supply chain management, asset
management and information technology. Although we have updated our internal controls that have been affected by the ERP
implementation, we do not believe that the ERP implementation has had an adverse effect on our internal controls over financial
reporting.
See “Management’s Report on Internal Control Over Financial Reporting” and “Report of Independent Registered Public
Accounting Firm” included in Item 8 of this Annual Report.
Item 9B. Other Information
