OneSubsea to supply industry’s first 15,000-psi subsea pump system for Stones development

Shell has awarded a contract to OneSubsea, a Cameron and Schlumberger company, to 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 award for the Stones development follows a technology qualification program.

The subsea processing systems scope of supply includes a dual pump station with two 3-megawatt single-phase pumps and two subsea control modules, a topside 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 processing center of excellence facility in Horsoy, Norway.

“Based on OneSubsea’s field-proven boosting technology, this is another innovative step forward for our subsea pumping systems,” said Jack Moore, Chairman and CEO of Cameron. “This boosting technology will be key for enhancing recovery and increasing production from the ultra-deepwater environment in the Lower Tertiary region of the Gulf of Mexico.”

The system will be tied back to the Stones FPSO. The system is expected to be ready for delivery from Horsoy in early 2018.
