MAN supports Aker Solutions’ Jansz-Io subsea compression study

July 18, 2019, by Offshore Energy Today

MAN Energy Solutions will support Aker Solutions’ FEED study for a subsea compression solution to be deployed at Chevron-operated Jansz-Io field, part of the giant Gorgon gas project, offshore Western Australia.

Norway’s Aker Solutions won the contract from Chevron for the subsea compression FEED study back in March, and Germany’s MAN this week said it had won a contract to support this project.

The German company said Thursday that its part of work on the FEED would cover the technology of the subsea compressors, which will be used to maintain output as the reservoir pressure drops over time. The company did not disclose the financial details of the contract.

Chevron’s Jansz-Io will be the first gas field outside Norway to used the subsea compression technology. It is located around 200 kilometers off the Australian north-west coast at a water depth of approximately 1’350 meters. Jansz-Io is part of the Gorgon project – one of the world’s largest natural gas developments.

“MAN’s subsea compression solution has already proven its reliability and benefits for Equinor’s Åsgard gas field in Norway, where the subsea compressors reached 50’000 hours of operation with practically no stops or interruptions in December 2018,” MAN Energy Solutions said.

Based on Barrow Island, the Gorgon project includes a liquefied natural gas (LNG) facility designed to produce 15.6 million metric tons of LNG per year.

The subsea infrastructure will also be used to transport the gas from the Jansz-Io offshore field to Gorgon’s onshore facilities with its three LNG processing units. The project also comprises a domestic natural gas plant.
