Attached herewith as Exhibit 99.1 is a press release, dated December 18, 2008,
whereby Acergy S.A. (the "Company") advises that at the Extraordinary General
Meeting of shareholders on December 18, 2008, resolution 1 (relating to an
increase of the number of the Company's Common Shares reserved for issuance
under the Company's 2003 Stock Option Plan from the current 6,310,000 Common
Shares to 8,710,000 Common Shares) was approved by shareholders, resolution 2
(relating to the adoption of the proposed Acergy S.A. 2008 Long Term Incentive

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. 333-9292, No. 333-74321, No. 333-124983 and No. 333-124997)
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, including the minutes of the Extraordinary General
Meeting, 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," "project," "will," "should," "seek," and similar expressions. 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: 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.
