Aker Solutions Bags Subsea Gas Compression Contract from Chevron
Aker Solutions has been awarded a major contract from Chevron Australia Pty Ltd to provide a subsea gas compression system for the Jansz-Io field, offshore Western Australia. The scope covers engineering, procurement and construction of the all-electric subsea gas compression system. It also includes interface responsibility, and assistance during installation and commissioning. The subsea gas compression system will include a complete compression station with three compressor modules and two subsea pump modules, all-electric control systems and actuators, structures including mud mats, high-voltage electrical power distribution system, several spare modules and equipment and various associated tooling.
The award follows completion of the front-end engineering and design (FEED) awarded in 2019. The work starts immediately with delivery expected during 2025. The project will be managed from Aker Solutions' headquarters in Fornebu, Norway. Client interface and operational planning will be handled from Perth, Australia.
The Jansz-Io gas field was first discovered in April 2000 and is located around 200 kilometers offshore the north-western coast of Western Australia, at water depths of approximately 1,400 meters. The Jansz-Io field is a part of the Chevron-operated Gorgon project, one of the world's largest natural gas developments.
The world’s first subsea gas compression system was delivered by Aker Solutions to Equinor’s Åsgard field in Norway in 2015. The technology had been developed through several years of strong in-house expertise and in close collaboration with the customer and suppliers such as MAN Energy Solutions and ABB. The technology has since been taken further, and the Jansz-Io Compression (J-IC) project will have close to three times more compression power than the Åsgard system at a comparable physical dimension and lower weights.
The Chevron-operated Gorgon Project is a joint venture between the Australian subsidiaries of Chevron (47.3 percent), ExxonMobil (25 percent), Shell (25 percent), Osaka Gas (1.25 percent), Tokyo Gas (1 percent) and JERA (0.417 percent).
