Attached herewith as Exhibit 99.1 is a press release, dated December 20, 2010, whereby Acergy S.A. (the “Company”) announced that at the Extraordinary General Meeting of Shareholders (the “Meeting”) held on December 20, 2010, the sole agenda item, to appoint Mr. Bob Long as the ninth Director of the Board of Subsea 7 S.A., was approved by over 99% of the votes cast.





Completion of the proposed combination of the Company and Subsea 7 Inc. is expected to occur in January 2011, subject to customary closing conditions.





The text of the minutes of the Meeting detailing the resolution proposed and the result of the poll on the resolution is attached herewith as Exhibit 99.2. Pursuant to Luxembourg law, the actual minutes are drawn up in the form of a notarial deed which will be available at a later stage. In case of inconsistency, the notarial deed will prevail.





The information set forth above shall be deemed to be incorporated by reference into the prospectuses forming a part of our Registration Statements on Form S-8 (No. 33-85168, No. 333-09292, No. 333-74321, No. 333-124983, No. 333-124997 and No. 333-166574) and our Registration Statements on Form F-3 and Form F-3/A (No. 333-86288) and to be a part of such prospectuses from the date of the filing thereof.  The attached press release and exhibit shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference in such filing.





Certain statements set forth above and contained in the press release furnished pursuant to this Form 6-K may include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements may be identified by the use of words like “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “forecast,” “project,” “will,” “should,” “seek,” and similar expressions.  These forward-looking statements include, but are not limited to, statements as to anticipated date of completion and the expected availability of the formal minutes of the Meeting.  The forward-looking statements reflect our current views and assumptions and are subject to risks and uncertainties.  The following factors, and others which are discussed in our public filings and submissions with the U.S. Securities and Exchange Commission, are among those that may cause actual and future results and trends to differ materially from our forward-looking statements: actions by regulatory authorities or other third parties; unanticipated costs and difficulties related to the integration of Acergy S.A. and Subsea 7 Inc. and our ability to achieve benefits therefrom; unanticipated delays, costs and difficulties related to the combination transaction, including satisfaction of closing conditions; our ability to recover costs on significant projects; the general economic conditions and competition in the markets and businesses in which we operate; our relationship with significant clients; the outcome of legal proceedings or governmental enquiries; uncertainties inherent in operating internationally; the timely delivery of ships on order and the timely completion of ship conversion programs; the impact of laws and regulations; and operating hazards, including spills and environmental damage. Many of these factors are beyond our ability to control or predict. Given these factors, you should not place undue reliance on the forward-looking statements.





This communication does not constitute an offer to purchase, sell, or exchange or the solicitation of an offer to sell, purchase, or exchange any securities of Subsea 7 Inc. or Acergy S.A.
