OneSubsea to provide subsea pump system for Shell’s Stones

OneSubsea, a Cameron and Schlumberger company, has been awarded a contract to supply subsea processing systems for the Shell Offshore Inc. Stones development in the Gulf of Mexico. 

OneSubsea notes that this award follows 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 9500 ft (2900 m).

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 Chief Executive Officer of Cameron, a parent company of OneSubsea.

“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 and it is expected to be ready for delivery from Horsoy in early 2018.
