CRP Subsea Booster Pump – Robust Multiphase Boosting for Demanding Offshore Fields

The OTECHOS CRP subsea booster pump is a compact and robust solution for multiphase boosting in offshore production systems.

As reservoirs mature, operators face declining pressure, increasing gas fraction, sand production, and longer tie-backs. Conventional high-speed pump technologies often struggle under these conditions, leading to wear, reduced performance, and costly subsea interventions.

The CRP addresses these challenges with a low-speed rotary displacement principle that maintains stable volumetric efficiency across varying flow conditions. It is inherently tolerant to gas, liquids, and solids, enabling reliable operation in complex multiphase environments.

Designed for durability and uptime, the CRP eliminates key failure drivers: no impellers exposed to erosion, no valves, and high tolerance to sand and transient flow. This significantly reduces wear and intervention frequency—critical for subsea installations where access is limited and cost is high.

Its compact and modular design supports flexible integration into subsea systems, including boosting, transfer, and long-distance multiphase transport.

By stabilizing production and reducing failure risk, the CRP enables increased recovery, extended field life, and lower total cost of ownership.
