Under the contract, which has been awarded by Chevron, McDermott will use its subsea construction vessel, North Ocean 102, to transport and install 30 miles of umbilicals and associated flying leads.
McDermott will complete the final jumper assembly at its Gulfport Spoolbase in Mississippi prior to installation by McDermott’s Derrick Barge 50 utilizing its deepwater lowering system.
The installation work is scheduled to start in the second quarter of 2016.
McDermott International Americas, Europe & Africa vice-president Scott Munro said: "This will be the second subsea project in the Jack and St. Malo fields that McDermott has carried out for Chevron, which demonstrates confidence in our ability to install subsea facilities in such challenging deepwater environments.
"McDermott successfully installed some of the industry’s largest and most complex umbilical end terminations in 7,200 feet of water, as part of the fields’ original development last year."
Located in the Walker Ridge area of the US Gulf of Mexico, approximately 280 miles south of New Orleans, Louisiana, the Jack and St. Malo fields are expected to have total recoverable resources in excess of 500 million oil equivalent barrels.
