PARIS – Nexans says it has been awarded a contract by Chevron U.S.A. Inc. to design, manufacture and supply a total of 138,000 ft (42 km) of power umbilicals and terminations for the Jack and St. Malo fields in the deepwater Gulf of Mexico.
The umbilicals will be loaded out from the new long-term storage carousel in Mobile, Alabama, dedicated to providing enhanced logistical support for customers in the Gulf of Mexico region.
The Jack and St. Malo fields are located within 25 miles (40 km) of each other approximately 280 miles (450 km) south of New Orleans, Louisiana, in water depths of 7,000 ft (2,100 m). The project will comprise three subsea centers tied back to a hub production facility with a capacity of 170,000 bbl/d of oil and 42.5 MMcfd of natural gas.
Nexans specialized cable manufacturing facilities in Halden, Norway, will design and manufacture the power umbilical for the Jack and St. Malo fields in two separate lengths, together with the associated umbilical termination heads (UTHs). On completion, the power umbilicals will be delivered to the newly constructed carousel at the Theodore Industrial Port in Mobile, Alabama, in 2013, where they will be held in storage until called-off by Chevron for installation.
The company says that the power umbilical integrates the functions of power cables and umbilicals in a single cable, enabling a high-voltage (HV) supply to be provided for deepwater projects.
