MAN Energy Solutions has been commissioned to supply five subsea compression units for the Chevron-operated Jansz-Io Compression Project. Aker Solutions has awarded MAN Energy Solutions the contract to supply five subsea compressor units to the Jansz-Io field, located around 200 km off the north-western coast of Western Australia at water depths of approximately 1,400 m.MAN Energy Solutions’ scope of work for the Jansz-Io project comprises the supply of five Subsea HOFIM compressor units, each with compressor frame size RB 45 with integrated MAN motor, size M43. Three compressor systems will be installed into the subsea modules while two further will serve as spare units. The Subsea HOFIM compressor was specifically adapted for underwater use. All components are designed to be as robust as possible to counteract the risk of corrosion inside the machine. Hermetically sealed and oil-free, the system uses seven-axes active magnetic bearings and a high-speed motor. This design means a large number of components are not required, including the gearbox, lubrication- oil system, instrumentation and valving as seen on conventional topside compressor solutions.The Jansz-Io field was first discovered in April 2000 and is a part of the Gorgon project, one of the world's largest natural gas developments. 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).
