Item 4.01.

Changes in Registrant’s Certifying Accountant

This Current Report on Form 8-K relates solely to the GlobalSantaFe Corporation 401(k) Savings Plan (the “Plan”).

The partners of UHY Mann Frankfort Stein & Lipp CPAs, LLP (“UHYMF”), the independent registered public accounting firm of the Plan, have announced that they were joining UHY LLP. UHY LLP is the independent registered accounting firm with which UHYMF has an affiliation. UHY LLP is a legal entity that is separate from UHYMF.

On May 14, 2007, UHYMF advised the Plan that it has ceased to provide audit services to the Plan and, thus, had resigned as the independent registered public accounting firm of the Plan. None of the reports of UHYMF on the Plan’s financial statements for either of the past two years contained an adverse opinion or disclaimer of opinion, or was qualified or modified as to uncertainty, audit scope or accounting principles. UHYMF did not report on the financial statements of the Plan for any subsequent interim period.

During the two most recent fiscal years of the Plan and any subsequent interim periods through the date of this report, there were no disagreements with UHYMF on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to the satisfaction of UHYMF, would have caused it to make reference to the subject matter of the disagreements in connection with its report, and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

UHYMF has been provided with a copy of these disclosures in response to Item 304(a) of Regulation S-K in connection with the filing of this report. A copy of the letter of UHYMF to the Securities and Exchange Commission stating its agreement with such disclosures is filed as Exhibit 16.1 hereto.

On May 14, 2007, UHY LLP was engaged as the Plan’s independent registered public accounting firm for the plan’s fiscal year ending December 31, 2006. The engagement of UHY LLP was approved by the Audit Committee of the Board of Directors of GlobalSantaFe Corporation. During the Plan’s two most recent fiscal years or subsequent interim periods, the Plan has not consulted with UHY LLP regarding the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Plan’s financial statements, nor did UHY LLP provide advice to the Plan, either written or oral, that was an important factor considered by the Plan in reaching a decision as to the accounting, auditing or financial reporting issue. Further, during the Plan’s two most recent fiscal years or subsequent interim periods, the registrant has not consulted with UHY LLP on any matter that was the subject of a disagreement or reportable event.
