McDermott Lands BHP Subsea Installation Gig in US Gulf

Journal of Petroleum Technology 

BHP awarded McDermott International a contract to provide a marine installation campaign for the Shenzi subsea multiphase pumping project in the deepwater US Gulf. The Shenzi development comprises approximately 15 subsea wells located across Green Canyon blocks 609, 610, 653, and 654, tied back to a tension-leg platform (TLP) hub in a water depth of 4,400 ft. The scope of the contract includes project management; detailed design and fabrication for a pump station suction pile; umbilical installation and flexible jumpers and flying leads installation; transport of all materials and equipment; and precommissioning services and other necessary testing and surveys. The $150-million subsea pumping project will allow for increased recovery from existing wells, with the operator anticipating an additional 4,000 B/D. "McDermott's North Ocean 102 vessel is uniquely qualified to transport and install the materials and equipment for the Shenzi project scope--as well as perform precommissioning testing and other necessary surveys to safely deliver for the customer," said Mark Coscio, senior vice president for McDermott's North, Central and South America region.
