Nexans wins power umbilical contract for Chevron-operated Jack and St. Malo fields in the deepwater Gulf of Mexico
Nexans, a worldwide leading expert in the cable industry, has been awarded a contract by Chevron U.S.A. Inc. to design, manufacture and supply a total of 138,000 feet (42km) of power umbilicals and terminations for the Jack and St. Malo fields in the Deepwater Gulf of Mexico. The umbilicals shall 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 feet (2,100 m). The project will comprise three subsea centers tied back to a hub production facility with a capacity of 170,000 barrels of oil and 42.5 million cubic feet of natural gas per day.
Nexans specialised 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 power umbilical is a cable product pioneered by Nexans that integrates the functions of power cables and umbilicals in a single cable, enabling a high-voltage (HV) supply to be provided for deepwater projects. A power umbilical includes a number of steel tubes as well as fiber optic elements and signal cables for control and monitoring purposes. By eliminating the need to transport and install separate power and control umbilical, the power umbilical significantly reduces transportation and installation costs.
"Winning this major power umbilical contract for the Jack and St. Malo fields is an important development for Nexans since Chevron is one of the leading lease-holders in the Deepwater Gulf of Mexico, which is a region where we are establishing a significant reputation as a key supplier of subsea technology," says Ragnvald Graff, Sales & Marketing Director, Energy Division, Nexans. "This contract award is also a vital step forward in our strategic approach to this region with the introduction of the new long-term storage carousel that now improves the level of local logistical support we can provide."
