Attached herewith as Exhibit 99.1 is a press release, dated December 15, 2008,
whereby Acergy S.A. (the "Company") announced the award from Angola LNG Limited
of a contract for the development of the nearshore/onshore segment of the
pipeline network required for the transportation of gas from Blocks 0, 14, 15,
17 and 18 to Angola LNG's plant in Soyo, Angola. Angola LNG Limited's
shareholders are affiliates of Chevron, Sonangol, BP, Total and ENI.

The contract awarded to a consortium of Acergy S.A. and Spiecapag, a subsidiary
of Entrepose Contracting (ISIN: FR0010204321), is for $550 million, of which
Acergy's share represents approximately $250 million.

Acergy's nearshore scope includes the engineering, procurement, fabrication and
installation of approximately 50km of pipeline from Blocks 0, 14, 15, 17 and 18.
It also includes the shore approach and above water tie-ins for these pipelines,
together with the offshore crossing and hydrotesting. Engineering will commence
with immediate effect with offshore installation scheduled to commence in the
fourth quarter of 2009, using Acergy Hawk, Acergy Legend and Acergy Polaris.

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 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 the combined value of the awarded contracts, statements as to
the date of commencement and completion of each awarded contract and statements
as to the scope and location of each awarded contract. 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.
