MultiBooster(tm) Subsea Multi-Phase Pump System

The MultiBooster(tm) subsea multi-phase pump system delivers improved oil recovery and facilitates longer step-out distances between subsea assests and host facilities by lowering pressure at the reservoir and increasing pressure in the production line.

Under development since 1998, the system utilizes twin-screw internals and Aker Kvaerner's pressure-volume regulator to provide a flexible and robust subsea solution.

This design provides several key benefits when handling multi-phase flow, including a wide performance envelope, low shear fluid handling, stable speed-controlled operation, and efficient slug dampening. The pump operates efficiently within a Gas Void Fraction (GVF) range of 0-95 percent and can maintain pressure up to 98 percent GVF. The pump can also operate at 100 percent GVF for a limited period, which aids start-up and prevents the need to prime the pump during such a scenario. With rotational speeds typically less than 2,000 rpm there is little risk of generating emulsions, and the pump can handle very heavy and viscous fluids in excess of 1,000 centistokes. The modular design of the pump system allows for easier subsea installation and retrieval.
