Dominion's dry-tree spar hull headed for GOM's Devils Tower field

By OGJ editors

HOUSTON, Mar. 28 -- Dominion Exploration & Production Inc., operator of Devils Tower field in the Gulf of Mexico, and partner Pioneer Natural Resources USA Inc. are preparing to receive what PT McDermott Indonesia (PTMI) says will be the "world's deepest dry-tree spar hull." The hull is en route to the field from PTMI's Southeast Asia yard at Batam Island in Indonesia where it was fabricated—a distance of 22,600 km.

The 11,700 tonne, 179 m, truss-spar hull was loaded onto a fast transportation vessel in a 10 hr operation during which the structure was pulled along two load-out skidways by tensioned strand jacks with pulling cables.

J. Ray McDermott's Gulf of Mexico DB50 derrick barge will install the hull in 5,610 ft of water on Mississippi Canyon Block 773 and will prepare the structure to receive the topsides, currently being fabricated at McDermott's Harbor Island yard.

PTMI and J. Ray McDermott Inc. are subsidiaries of McDermott International Inc.
