The $120-million order is to supply the overall electrical power system for the Jansz-Io Compression (J-IC) project, which moves gas from the deep seas to shore.
The Jansz-Io field is about 200 km (124 mi) offshore northwestern Australia, at water depths of about 1,400 m (4,593 ft). The field is a part of the Chevron-operated Gorgon natural gas project. Its partners are ExxonMobil, Shell, Osaka Gas, Tokyo Gas, and JERA.
The $4-billion J-IC project includes the construction and installation of a 27,000-metric ton, normally unattended floating field control station, 6,500 metric tons of subsea compression infrastructure, and a 135-km (84-mi) subsea power cable connected to Barrow Island.
ABB will provide the majority of the electrical equipment, both topsides and subsea. The project will combine two of its core technologies – power from shore and variable speed drive long step-out subsea power – for the first time. According to the company, the electrical system will be able to transmit 100 megavolt-amperes over about 140 km (87 mi) and at depths of 1,400 m.
The contract was awarded following concept development and a front-end engineering and design study. Work will start immediately, and the subsea compression system is expected to be in operation in 2025.
