Description

Modular. Configurable. Scalable.

Our disruptive subsea processing technologies help enhance your field performance, extend production, and solve topside capacity challenges. Recoverable and potentially reusable, the unmanned facilities help improve field economics while securing and increasing flowline production capacity and in parallel reducing carbon emissions.

Improve field economics

From long-distance tiebacks of remote and marginal fields to mature fields, our subsea processing solutions create incremental value by enabling field development that otherwise would be constrained by the host facility. Located on the seabed, these proven, unmanned facilities are easy to install, increase oil recovery, and require low maintenance.

Enabling technology

Our pioneering Seabox™ subsea seawater treatment module and SWIT™ sulfate removal system enhance oil recovery and reduce the health, safety, and environmental (HSE) impact of water injection, including lower power consumption and chemical use. The world’s first commercial subsea water treatment and filtration systems have won OTC’s Spotlight on New Technology Awards: Seabox in 2018 and SWIT in 2020.

Our subsea processing technologies safely, efficiently, and reliably operate in water depths of up to 3,000 m, temperatures down to freezing, and pressures as required for your water injection solution.
