French oilfield services company Technip has been awarded a contract for the development of subsea infrastructure for the Shell-operated Stones development in the U.S. Gulf of Mexico.
According to Technip, two subsea production tie-backs to the Floating Production, Storage and Offloading (FPSO) vessel will be included in the service. The Stones development is located in 2,896m (9500ft) of water approximately 320km (200 miles) offshore Louisiana in the Walker Ridge area. When installed, the Stones FPSO will be the deepest FPSO development in the world.
The contract covers engineering of the required second pipeline end terminations (PLETs), fabrication of the PLETs and piles, installation of the subsea production system, inclusive of associated project management, engineering and stalk fabrication.
Technip’s 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.
