Aker Wins Feed Contract on Oz Jansz-Io Field

Norway’s Aker Solutions has bagged a master contract to support the delivery of a subsea compression system for the Chevron Australia-operated Jansz-Io field offshore Australia.

The first service order under the master contract will be for front-end engineering and design (Feed) of a subsea compression station that will boost the recovery of gas from the field, Aker said March 12. The Feed scope will also cover an unmanned power and control floater, as well as overall field system engineering services. The field control station will distribute onshore power to the subsea compression station. 

The Norwegian company said that the gas compression system will boost recovery of gas more cost-effectively and with a smaller environmental footprint than a conventional semi-submersible compressor solution.

Compression will help maintain plateau gas production rates as reservoir pressure drops over time. While such compressors have typically been installed on platforms at surface level, placing them on the seabed and near the wellheads improves recovery rates and reduces capital and operating costs, Aker added.

The Jansz-Io field is located around 200 km off the north-west coast of Western Australia at approximately 1,350 meters below the surface. The Jansz-Io field is a part of the Chevron Australia-operated Gorgon Project.
