Subsea Pump Control System
Optimal operation of the subsea boosting system
Accelerate response times while safely monitoring and controlling pumps.
With no requirements for an upstream separation facility or an antisurge system, Multiphase WGC wet gas compressor greatly simplifies subsea system operations.
The contrarotating machine is specifically designed for pressure boosting of unprocessed wellstream. This unique configuration—developed in collaboration with Statoil and Shell—enables a compact and robust design that is easy to install by use of light intervention vessels and is based on the well-proven design developed for subsea boosting pumps.
The main driver in the development of the multiphase compressor was to increase recovery rates and to cost-effectively increase the tieback distances of subsea gas fields.
The Gullfaks field, operated by Statoil and located in the North Sea, saw the first commercial deployment in the world for subsea wet gas compression. Statoil estimates that the recovery rate will increase by 22 million barrels of oil equivalent by using the wet gas compression system. The wet gas compression station for Gullfaks was installed approximately 15 km away from the Gullfaks C platform.
Schlumberger announced today an award to OneSubsea by A/S Norske Shell of a frame agreement for an engineering, procurement, construction and installation (EPCI) contract for the supply of a subsea multiphase compression system for the Ormen Lange Field in the Norwegian Sea.
Upstream technologies recognized for excellence in innovative concept, design and application.
Successful development of the novel pressure control system prevented production curtailment altogether.
Two-motor contrarotating design ensures efficient power system compatibility and game-changing step-out topologies.
