Chevron Australia has let a master contract to Aker Solutions for a subsea compression system for the company’s Jansz-Io field offshore Western Australia. The first stage of the contract is the front-end engineering and design of a subsea compression station that will boost gas recovery at the field, which is part of the overall Gorgon region development that supplies gas to the 15.6 million-tonne/year LNG and domestic gas plants on Barrow Island.
