OVERVIEW

Why OneSubsea compression?

Placing the compressor on the seabed saves the considerable cost of building and operating a topside facility and, with the compressor closer to the wellhead, you can benefit from increased production because of a lower pressure drop in the pipeline downstream. This means you use less power – and have a lower carbon footprint – than with alternative solutions.

Core benefits

Energy consumption reduction

Uses less energy than topside compression (about 67% less for a gas subsea tieback of 120 km with 95% uptime over 10 years).

Lower emissions

Decreases CO₂e emissions compared with topside compression (about 67% less CO₂e for a gas subsea tieback of 120km with 95% uptime across 10 years).

Producing more with less

Our solution is approximately half the weight of a conventional subsea compression system.

Application

Conventional compression systems for high-capacity applications, in compliance with the most stringent requirements and able to tolerate the most challenging conditions
Well stream compression systems for low- and medium-capacity applications
Compensate for the losses generated in the production line between the subsea wells and the topside host

Features

Wet gas compressor designed for pressure boosting an unprocessed well stream, based on our multiphase boosting pumps
Can operate in any flow regime and tolerates sand and solids
Our integrated approach ensures all risks are identified and mitigated in the early stages of field development planning to provide complete system availability
