Attached herewith as Exhibit 99.1 is a press release, issued on January 15,
2010, whereby Acergy S.A. (the "Company") announced the publication of materials
for the 2010 Extraordinary General Meeting ("the Meeting") including the Notice
of Meeting to be held on February 16, 2010 at 12.00 p.m. local time at the
offices of SGG S.A., 412F, route d'Esch, L-2086 Luxembourg for the purpose of
considering resolution 1 of the December 17, 2009 Extraordinary General Meeting
Agenda.

It was noted at the Extraordinary General Meeting of Shareholders on December
17, 2009 that the required quorum of 50% of the outstanding shares for
resolution 1 was not present and this Meeting was therefore not able to consider
this resolution.

The Board of Directors therefore decided to call an Extraordinary General
Meeting to consider resolution 1. At this Meeting there is no requirement for
quorum. However, to approve the proposed resolution a 2/3rd majority of the
votes cast at the Meeting will be required.

Proxies already received for the December 17, 2009 Extraordinary General Meeting
remain valid for this Meeting and Shareholders of record as of October 30, 2009
are entitled to vote at the Meeting. Those Shareholders who have not yet cast
their votes may do so by submitting the proxy card as instructed, or
alternatively may attend the Meeting at the above address. The new deadline for
submission of votes for American Depositary Receipt holders is February 8, 2010
and for holders of Common Shares February 9, 2010.

The materials for this Meeting are attached to this announcement and can be
found on the Acergy website: www.acergy-group.com/public/February2010EGM

Attached herewith as Exhibits 99.2, 99.3, 99.4, 99.5, 99.6 and 99.7,
respectively, are the following materials regarding the Meeting:

     99.2 Chairman's letter dated January 15, 2010 inter alia advising of the
          Meeting.

     99.3 Notice of the Meeting on February 16, 2010.

     99.4 Letter from DnB NOR Bank ASA to Shareholders of the Company regarding

which represents one Common Share of the Company) of record as of October 30,
2009.

Certain statements set forth above and contained in the press release and above
materials 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. These statements include, but are not limited to,
statements as to the expected timing and purposes 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: 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

                                        2

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.
