McDermott International has secured a contract to support the expansion of the Jack and St. Malo fields in the US Gulf of Mexico.

Under the contract, McDermott will transport and install subsea umbilicals, manifolds, jumpers and flying leads for Chevron USA.

McDermott expects to use its North Ocean 102 subsea construction vessel to transport and install 30 miles of umbilicals and related flying leads in around 7,200ft of water.

The last jumper assembly is due to be completed at McDermott’s Gulfport Spoolbase, Mississippi, before installation by the company’s Derrick Barge 50, using its deepwater lowering system.

The installation programme is anticipated to start in the second quarter of 2016.

"This project demonstrates confidence in our ability to install subsea facilities in such challenging deepwater environments."

McDermott International vice-president of Americas, Europe & Africa 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 within 40km of eachother, in aproximately 2,100m of water in the Walker Ridge area, the Jack and St. Malo fields were discovered in 2004 and 2003, respectively.

Chevron started crude oil and natural gas production at the fields in December 2014.

The Jack / St. Malo project has a production capacity of 170,000 barrels of oil and 42.5 million cubic feet of natural gas per day, with the potential for future expansion.
