On April 30, 2007, Acergy S.A. ("Acergy S.A." or the "Company") issued the
following notification to the Oslo Stock Exchange:

     Acergy S.A. issued a press release on March 28, 2007 in which it
     was stated that the record date for proposed payment of dividend to
     be May 31, 2007. Unfortunately, in the notice to shareholders of
     Annual General Meeting 2007, the record date for such proposed
     dividend is set to be May 25, 2007.

     The correct record date is nevertheless May 31, 2007, which has
     or will be reflected in newspaper announcements in Norway
     and Luxembourg.

The information provided above 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 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 the Company's current views and assumptions
and are subject to risks and uncertainties. The following factors, and others
which are discussed in the Company's 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 the Company's
forward-looking statements: the Company's ability to recover costs on
significant projects; the general economic conditions and competition in the
markets and businesses in which the Company operates; the Company's relationship
with significant clients; the outcome of legal proceedings or governmental
inquiries; 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 the Company's
ability to control or predict. Given these factors, you should not place undue
reliance on the forward-looking statements.
