Coflexip Stena Offshore (Nasdaq: CXIPY; Premier Marche: CFI FP) announced today that one of its Gulf of Mexico based entities, Coflexip Stena Offshore Inc., has been awarded by Shell Exploration & Production Company a contract for the installation of the infield flowlines and risers to be completed by the CSO Deep Blue, for the ultra deepwater NaKika project located in the Mississippi Canyon, in the Gulf of Mexico, at water depths ranging from 5,800- 7,000 feet (1,800-2,100 meters).

This project defines new frontiers for the industry, both in terms of working depths and the level of technology applied to the design and installation of flowlines and risers. The CSO Deep Blue, which will be operating from CSO's Gulf support base in Mobile, Alabama, will demonstrate its unique and versatile pipe laying capabilities. The vessel's systems will enable the installation of the deepest ever pipe-in-pipe system using the J-lay solution, and the deepest ever fully reeled SCR, as well as the deepest ever pipe-in-pipe SCR.

The NaKika project ties back five fields using subsea techniques, to the NaKika floating development and production platform located in Mississippi Canyon block 474, in the Gulf of Mexico. The contract awarded to CSO Inc. involves the installation in water depths up to 2,130 m (7,000 ft) of over 100 miles of high specification flowlines including an 8" reeled gas flowline, an 8" in 12" reeled pipe-in-pipe system, a J-laid 10" in 16" pipe-in-pipe system and steel catenary risers (SCRs). The SCRs which will be installed by the J-lay method, will include an 18" oil export riser, a 20" gas export riser and two pipe-in-pipe steel catenary risers of 8" in 12" and 10" in 16" respectively, as well as two 8" risers and two 4.5" gas lift risers.

CSO will also be responsible for the design and fabrication of the 8" in 12" reeled pipe-in-pipe system, based on a similar successful project recently completed in the Gulf of Mexico where CSO designed and installed one of the deepest pipe-in-pipe flowlines and a complete dynamic steel catenary riser with the reeled method.

Onshore fabrication of all the reeled flowlines and SCRs sections, as well as the mobilization of the J-lay operations, will be performed at CSO's new construction support base located in Mobile, Alabama.

The flowlines and the steel catenary risers, will be installed by the CSO Deep Blue, the Group's new ultra deepwater pipelay vessel, between Q3 2002 and Q2 2003 during two installation campaigns. The vessel will utilize both her J-lay and reel lay capabilities in deepwaters; these are tasks for which she has been designed by CSO, anticipating the future needs of clients for their deep and ultra deep water developments.

Commenting on the award, Ken Hulls, Managing Director of Coflexip Stena Offshore, Inc. said: "The quality of the pipelay vessel required, and the technology being used for installation on this project, will expand the
frontier of what is reliable and economically achievable in deepwater to a new level. This award confirms the technical superiority and the competitive advantage in combining, on the same vessel, the J-lay capability to lay larger diameter lines and technically complex SCRs, together with the reel lay method which allows installation of PiP flowlines and full length smaller SCRs at a faster rate."

Kevin Wood, Executive Vice President, Operations and Projects, for North America, the North Sea and Asia Pacific, added: "Our success in being awarded the NaKika project is a further consolidation of CSO's strategy of becoming a leading provider of ultra deepwater flowline and riser solutions in the Gulf of Mexico. The commissioning of our new construction support base in Mobile, Alabama in April 2001, and the arrival of the CSO Deep Blue this summer, culminates a key part of our strategy to provide our clients with solutions for their deepwater developments. We are pleased to be able to provide the CSO Deep Blue for Shell's technically challenging deepwater installation project, and look forward to further increasing our level of service to our Gulf of Mexico clients."
