McDermott International, announced that one of its subsidiary companies was awarded fabrication and installation work from Chevron U.S.A. Inc. to support the development of the Jack and St. Malo fields in the Gulf of Mexico. The project will be included in McDermott's first quarter 2011 bookings.

Work will begin in 2013, with the start of fabrication of 21 rigid jumpers at McDermott's Morgan City fabrication facility in Louisiana. Offshore installation will begin in early 2014 using McDermott's subsea construction vessel North Ocean 102 (NO102) and the DB16.

"We are pleased to be able to support Chevron's deepwater developments in the Gulf of Mexico and believe that our combined solution of NO102's high payload and top tension capacity coupled with our ability to fabricate the high spec jumpers in house provides a unique benefit for this project's delivery," said Stephen Johnson, president and chief executive officer of McDermott.

The NO102 and its crew will transport and install more than 60 miles of umbilicals, including three control and two power umbilicals. The jumpers and remaining subsea controls system components, including more than 80 flying leads, will be installed by the DB16.

The 427-foot NO102 enables McDermott to offer versatile installation capabilities in the flexible pipe and product market worldwide. The vessel has two cranes and a moon pool to support deepwater subsea construction work and has a fast transit speed. It is currently equipped with a 7,000-tonne capacity cable and umbilical and flexible pipe carousel with horizontal lay system.

Plans are underway to upgrade the vessel's capability by installing a high-capacity flexible-lay system for ultra deepwater installation work. The upgrade will include installation of a new 250-tonne crane.

North Ocean 105 (NO105), the sister ship to NO102, is currently under construction at a Spanish shipyard. The 427-foot vessel will be outfitted with a high capacity rigid-reeled pipe-lay system with top-tier payload capacity. The system will also accommodate installation of flexible products including submarine cables and umbilicals and flexible pipelines. The anticipated delivery date of the NO105 is 2012.

Located in up to 7,150 feet of water in the US Gulf of Mexico Walker Ridge lease blocks, the Jack South and St. Malo North and South subsea drill centres tie back to the Jack and St. Malo floating production platform.
