Wood announced on Wednesday that it has secured a contract with Chevron Australia to provide subsea integration and flow assurance front-end engineering design (FEED) services for the Jansz-lo compression project offshore Western Australia.

The project – the first outside of Norway to use subsea compression technology – will maintain gas supply to the existing onshore Gorgon liquefied natural gas (LNG) facility.

Wood said it will lead as system integrator of the technology, providing independent flow assurance, subsea design and construction engineering support during the FEED. Effective immediately, Wood’s one-year contract will be delivered by its team based in Perth.

The Jansz-Io field – part of the Chevron-operated Gorgon Project, one of the world's largest natural gas developments – is located around 200 kilometers offshore the northwest coast of Western Australia at approximately 1,350 meters water depth.

In March Aker Solutions, which delivered the world's first subsea compression system for Equinor's Åsgard field offshore Norway in 2015, was awarded a master contract to support the delivery of a subsea compression system, including front-end engineering and design (FEED) of a subsea compression station, an unmanned power and control floater and overall field system engineering services.

Compression helps to maintain plateau gas production rates as reservoir pressure drops over time, but such compressors have typically been installed on platforms over sea level. Placing this equipment on the seabed and near the wellheads improves recovery rates and reduces capital and operating costs.
