Offshore staff

HOUSTON – Shell Offshore Inc. has awarded OneSubsea a contract to supply subsea processing systems for the Stones project in the Gulf of Mexico.

The award comes after a technology qualification program and will deliver the industry’s first 15,000-psi subsea pump system, to be installed in the Gulf of Mexico at approximately 9,500 ft (2,900 m). The system will be tied back to the Stones FPSO.

The subsea processing systems scope includes a dual pump station with two 3-MW single-phase pumps and two subsea control modules, a topsides power and control module, a barrier-fluid hydraulic power unit with associated spares, as well as installation and maintenance tools.

Manufacturing and testing will take place at OneSubsea’s facility in Horsøy, Norway, for delivery in early 2018.
