Aker Solutions has been awarded a master contract to support the delivery of a subsea compression system for the Jansz-Io field operated by Chevron Australia off the coast of Australia.

Aker Solutions' first order of service under the master contract will be for front-end engineering and design of a subsea compressor station that will drive gas recovery from the field. The FEED scope will also cover an unmanned power and control float, as well as general field systems engineering services. The field control station will distribute onshore power to the subsea compressor station.

The gas compression system will drive gas recovery more economically and with less environmental impact than a conventional semi-submersible compressor solution. Aker Solutions in 2015 delivered the world's first subsea compression system for Equinor's Åsgard field off the coast of Norway.

“Aker Solutions has been working closely with its partners MAN Energy Solutions and ABB to reduce the size and cost of the compression system,” said Luis Araujo, executive director of Aker Solutions. “We are excited to be working with Chevron Australia on our compressor technology to drive recovery in the Jansz-Io field.”

Compression will help maintain plateau gas production rates as reservoir pressure decreases over time. While such compressors have typically been installed on platforms above sea level, placing them on the seabed and close to the wells improves r rates.recovery and reduces operating and capital costs.

The Jansz-Io field is located approximately 200 km off the northwest coast of Western Australia, approximately 1.350 meters below the surface. The Jansz-Io field is part of the Gorgon Project, operated by Chevron Australia, one of the largest natural gas developments in the world.

“Australia will be the first location outside of Norway to use subsea compression technology. Aker Solutions has been present in Western Australia for over 20 years and we look forward to working collaboratively with the local industry on this development,” said Araujo.
