Technip awarded additional subsea contract for the Stones project development in the Gulf of Mexico
Leveraging its subsea vertical integration
Technip was awarded by Shell Offshore Inc. (“Shell”) a contract for the development of subsea infrastructure for the Stones project. Included in the service are two subsea production tie-backs to the Floating Production, Storage and Offloading (FPSO) vessel. The Stones field is located in the Walker Ridge area in the US Gulf of Mexico, at a water depth of 2,930 meters along the pipelay route.
The contract covers:
- engineering of the required second pipeline end terminations (PLETs),
- fabrication of the PLETs and piles,
- installation of the subsea production system(1), inclusive of associated project management, engineering and stalk fabrication.
Technip will leverage its integrated approach in the subsea business. Its operating center in Houston, Texas, USA, will perform the overall project management. The flowlines will be welded at Technip’s spoolbase in Mobile, Alabama, USA. The offshore installation is scheduled to be performed by the Deep Blue, the Group’s flagship vessel for deepwater pipelay.
Technip offers engineering capabilities in executing ultra-deepwater installation projects with continued cost effective solutions for its clients.
(1)The production system is comprised of dual 8-inch insulated flowlines associated with PLETs involving a manifold and associated suction piles being installed as part of this system.
