Chevron chooses French company for Wheatstone processing

Chevron Australia has chosen French company Technip to perform front end engineering design (FEED) for the offshore processing platform associated with the Wheatstone Project off Western Australia.

The upstream portion of the project comprises development of gas fields in the WA-17-R and WA-253-P petroleum titles located on the Northwest Shelf offshore Western Australia at water depths of 70 to 200 meters.

Subsea gas gathering systems will transport production to the processing platform where the gas and condensate will be respectively dehydrated, dewatered, compressed and exported through a 200-kilometer export pipeline to the onshore gas plant located at Ashburton North, 12 kilometers west of Onslow, on the Pilbara coast of mainland Western Australia.

Technip’s contract involves selection of the optimum offshore configuration and development of the full FEED for the selected concept, including flow assurance of the associated flowlines and pipelines.

The platform topsides is anticipated to be one of the world’s largest single integrated floatover installations, according to Technip.
