    The scope of work includes project management, engineering, procurement and installation of two export pipelines consisting of 160 miles of 18in pipeline, 12 miles of 14in pipeline and two 14in steel catenary risers (SCR). CSO will also be responsible for hooking up of the SCRs to the new-built Dominion Exploration Devils Tower Spar, diving work in shallow waters and all pre-commissioning activities on the oil and gas export lines including pigging, hydrotest and drying of the gas export line.

    The pipelines will be fabricated by CSO at its new spoolbase at Mobile, Alabama, and the installation will be completed by the CSO Deep Blue, CSO's new ultra deepwater pipelay and construction vessel, utilising the reel lay method. Installation is scheduled to take place in the second half of 2002 with the riser hook-up being completed in January 2003.
