Acergy S.A. (NASDAQ: ACGY) (Oslo Stock Exchange: ACY) announced today the charter of the Toisa Proteus from the Toisa/Sealion Group of companies. The ship will provide offshore construction and diving services in the Asia Pacific region for a period of three years upon completion of her current charter. The Toisa Proteus, which was built at the Van Der Geissen yard in 2002, is an offshore heavy construction and diving support ship of 132 metres over all and 22 metres beam. She has Class 3 dynamic positioning, a heave compensated crane with 400 metric tonne lift capability and a saturation diving system for 14 divers.

Acergy also announced today the receipt of a Letter of Intent valued at approximately $35 million from Tanker Pacific Offshore Terminals Pte. Ltd., for the transportation and installation of the Submerged Turret Production Buoy moorings for the FPSO, flowlines, risers and well control umbilical for a field development off the coast of New Zealand. Offshore installation, which will take place in water depths of up to 100 metres, is scheduled for late 2007 from the Toisa Proteus.

Jeff Champion, Vice President Acergy Asia and Middle East, said, "Following success on the Casino project and continued activity on the Sakhalin and Dai Hung projects, this Letter of Intent for work off New Zealand will lead to further development of our position in the SURF and deepwater market in Asia Pacific.
