HOUSTON, Nov. 1 -- Industry organization DeepStar awarded to a Halliburton Co. division the contract for a conceptual engineering study of a spar-deep draft caisson vessel in 10,000 ft water depth in the Gulf of Mexico.
Halliburton KBR, formerly Kellogg Brown & Root, began work on the project in early October; completion is scheduled for March 2002. The study involves engineering and cost analysis of a spar-DDCV for very large topsides and a large number of risers that will work in ultradeep waters on a high pressure-high temperature reservoir.
KBR will review three options for mooring system and riser design: steel mooring with steel risers; polyester mooring with steel risers; and polyester mooring with composite risers.
The scope of the contract includes conceptual design and analyses; developing major operations sequences and identifying key equipment needed for fabrication and installation; developing cost and schedule estimates; and documenting analyses, design, drawings, schedules, costs, findings, and recommendations.
