Aker Solutions (stand 5C100) is launching its MultiBooster, a new, up to 6MW subsea multiphase pump to help operators maximize production from existing oil and gas fields, at SPE Offshore Europe this week.

Aker Solutions says the now qualified, standardized and modular design pump is more powerful than any other pump currently available, making it ideal for increasing the pressure on long step-outs and tie-backs.

The centrifugal pump is driven by new subsea induction motors, which can boost from 1-6 MW with the same mechanical platform by varying the pump impellers and the number of stages.  

The system is fitted with advanced condition monitoring, including proximity probes to accurately measure radial and axial displacements of the rotor, with integrated software and data analytics, to maintain efficiency and for cost effectiveness.

The industry is looking to get more out of the assets they already have. In many cases, these assets include older fields which require more pressure—that’s where the MultiBooster comes in, said Marco Gabelloni, business development director at Aker Solutions.

Aker Solutions says the MultiBooster’s combination of generated pressure and boost capacity means it can be deployed in a wide range of oil fields with various flow rates, water depths (down to 3000m) and long tie-back distances.

System performance has been proven through an extensive testing campaign in a full-scale multiphase test loop at Tranby, Norway, with varying mixtures of water and gas to demonstrate the MultiBooster’s gas handling capabilities.

Together with the POWERJump, which was qualified earlier this year, the MultiBooster complements Aker Solutions portfolio of subsea multiphase pumps by providing solutions for all types of boosting applications.
