Nexans wins power umbilical contract for oil field project in Gulf of Mexico

Nexans reports that it has been awarded a major contract by OneSubsea (a Cameron & Schlumberger company) to design, manufacture and supply an integrated power umbilical solution and associated termination hardware for Exxon Mobil Corporation's Julia oil field development in the deepwater Gulf of Mexico.

A press release said that the company will provide an innovative 23-km long solution that integrates power cables and umbilical services in a single cross-section that will be deployed at water depths in excess of 2,000 meters to tieback the Julia oil field development to subsea production facilities. This approach, it said, enables a high-voltage (HV) supply to be provided for deepwater projects via the power umbilical, which includes a number of steel tubes as well as fiber optic elements and signal cables for control and monitoring purposes. For the Julia project, scheduled for production start-up in 2016, the power umbilical will operate subsea pumps supplied by OneSubsea.

The power umbilical for the Julia field will be designed and manufactured at the specialized Nexans subsea cable manufacturing facilities in Halden, Norway, the release said. In it, Krister Granlie, vice president hybrid underwater cables, Nexans Norway, said that the contract was important. "It is clear that a growing number of operators are recognizing that power    umbilicals, while complex in design, offer a more elegant and cost-effective approach than the transportation and installation of separate subsea power cables and umbilicals."
