Technip gets deepwater GoM Stones subsea work from Shell

Offshore staff

PARIS – Shell Offshore Inc. has awarded Technip (Paris:TEC) an engineering, procurement, and installation contract for subsea infrastructure at Stones in the Gulf of Mexico.

Technip will install the subsea production system and Stones lateral gas pipeline, and also will provide associated project management, engineering and stalk fabrication.

The production system design calls for dual 8-in insulated flowlines associated with pipeline end termination (PLET), and dual 8-in steel lazy wave riser (SLWR). The Stones lateral gas pipeline is comprised of a single 8-in gas pipeline associated with PLET, in-line sled, and a single 8-in SLWR.

This field is in the Walker Ridge area in the US Gulf of Mexico, at a water depth of approximately 2,900 m (9,500 ft). This development will host the deepest water FPSO unit in the world and will be Shell’s first FPSO in the GoM.

Technip in Houston will perform the overall project management. The flowlines and risers will be welded at Technip’s spoolbase in Mobile, Alabama. The offshore installation is expected in the second half of 2014 by the Deep Blue, Technip’s deepwater pipelay vessel.
