London, England - December 15, 2008 - Acergy S.A. (NASDAQ- GS: ACGY; Oslo Stock
Exchange: ACY) announced today 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

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.

Olivier Carre, Vice President Acergy Africa and Mediterranean, said: "We are
delighted to have been awarded this contract which represents an important
