               ACERGY S.A. AWARDED $65 MILLION CONTRACT IN TUNISIA

London, England - November 22, 2006 - Acergy S.A. (NASDAQ NM: ACGY; Oslo Stock
Exchange: ACY) announced today that it had been awarded a contract by BG Tunisia
Ltd for construction work on the Miskar field offshore Tunisia.

The contract, valued at approximately $65 million, is for the installation,
tie-in and commissioning of two 3 kilometre 10 inch diameter pipelines, together
with a well control umbilical and riser, to tie back three subsea wells to the
Miskar A platform. Offshore installation is scheduled for the fourth quarter of
2007. The project is being undertaken by Acergy Northern Europe and Canada.

Oeyvind Mikaelsen, Vice President Acergy Northern Europe and Canada, said "We
welcome this award from BG Tunisia. The Miskar tie-back contract is very similar
to the type of work that we undertake regularly in the North Sea and fits well
with our pipelay schedule for 2007 which is filling up quickly."
