Aker Solutions has teamed with German firm Man Diesel & Turbo to develop the next-generation in subsea compression systems that can be used even at the smallest oil and gas fields.
The technology is aimed at improving recovery and lowering costs, compared with conventional platform solutions.
Aker delivered the world’s first full-scale subsea gas compression system at the Åsgard field in Norway.
A key objective of the partnership with Man is to develop new, cost-effective technology for high-capacity subsea compression systems.
The alliance aims to mate Aker’s subsea capabilities with Man’s leading turbomachinery technology and gas compression expertise. The compression systems will be based on proven technology and for use at small subsea fields as well as large deposits such as Åsgard.
Aker Solutions subsea business head Alan Brunnen said: “Åsgard was a game-changer that moved compressors from platforms to the seafloor to improve recovery rates, reduce costs and enhance safety.
“We’re taking the technology further to provide compression systems that are smaller, lighter and cheaper without compromising on effectiveness.”
As part of the alliance, Aker’s capabilities in subsea processing, compression systems, controls, systems and interventions would be combined with MAN Diesel & Turbo’s turbomachinery technology and expertise in gas compression.
Compressors are used to maintain output as reservoir pressure at gas-producing fields decline. Aker claims that placing them on the seabed near the wellheads boosts recovery rates, leaves a smaller environmental footprint and is safer to operate than on a platform.
Man senior vice-president Mathias Scherer, said: “Our strong cooperation over several years ensures our ability to focus delivering the safest, most reliable and cost-efficient technology possible for developments of all sizes.”
Aker delivered the subsea compression system at Åsgard, which came on stream on September 17, to enable the recovery of an additional 306 million boe from the Statoil-operated field.
Man, a sub-supplier to the project, is the first turbomachinery manufacturer to have developed a centrifugal compressor installed on the seafloor.
