Increase Recovery and Accelerate Production
Lower wellhead pressure to improve oil recovery; boost early revenue with 20%–200% higher flow rates.
Improve Flow Assurance
Mitigate slugging with more benign flow regimes and facilitate hydrate and wax management because of heat transfer from the pump and motor.
Lower Capex and Opex
Simplify subsea infrastructure, reduce energy consumption, and improve system uptime (via quicker startup and fewer interventions).
Enhance Production Management
Maintain production from weaker wells without any adjustments to the stronger ones.
Facilitate Heavy Oil Production
Produce oil with viscosities up to 30,000 cP.
Produce from Otherwise Unavailable Fields
Compensate for the pressure drop over long tieback distances with higher pressures at the pump outlet.
How Can You Evaluate Boosting System Integrity and Ensure Uptime?
The decarbonization and accelerated production enabled by boosting systems are crucial to subsea asset optimization. But how can you use AI to monitor and optimize performance and proactively ensure pump health?

A comprehensive offering for diverse flow regimes

With >4 million running hours accumulated, OneSubsea boosting pumps are inherently robust and wear-resistant, suitable for use with fluids containing sand particles—a common occurrence in most subsea production systems.

All pumps are configured with an electric motor mounted on top and the pump section at the bottom, both within a vertical cartridge that is fully encapsulated in a pressure housing. The optimized compact design enables subsea installation and retrieval by light vessels.

Depending on how a field develops, any pump type can be fitted into the standardized subsea interface, giving you the option to replace one pump with a different type to meet the requirements of your field throughout its life.

An integrated approach

Total system solutions ensure that all risks are identified and mitigated in the early stages of field development planning. These solutions include all the equipment needed to operate the pumps during startup, shutdown, and normal flowing conditions; they are combined with operational support to provide complete system availability.
