VIDEO: Wheatstone Project progresses towards completion

The project involves the installation and operation of two export pipelines to export pipelines to transport gas from the fields to the onshore plant, with the first of these lines to be approximately 225 km in length, and 1120 mm in diameter.

The second pipeline will be laid to allow future tie-ins from other gas fields, extending from the LNG plant out beyond the depth required for stabilisation.

The 109 km Wheatstone-Ashburton West Pipeline, completed in 2014, runs between the project’s domestic gas plant and DUET’s majority-owned Dampier to Bunbury Natural Gas Pipeline at Ashburton West.

Equipment and modules continue to be delivered and installed at the facility, with all LNG Train 1 cold boxes now on site.

Slug catcher header and piping systems have also been installed, which will separate condensate from gas at the inlet of the plant before further gas processing.

A look at progress on the Wheatstone Project

At the materials offloading facility, the breakwater is complete and the loading platform has been installed on the 1.2 km product loading jetty.

A 440-person accommodation vessel has been connected to the offshore gas processing platform, 225 km from Ashburton North, to support hookup and commissioning activities now under way.

Installation of subsea manifolds is complete and subsea equipment and flow lines are now being installed on the Wheatstone and Iago gas fields.

The project is a joint venture between the Australian subsidiaries of Chevron (64.14 per cent), Apache Energy (13 per cent), Kuwait Foreign Petroleum Exploration Company KUFPEC (13.4 per cent) and Kyushu Electric Power Company (1.46 per cent), together with PE Wheatstone Pty Ltd (part owned by Tokyo Electric Power Company, 8 per cent).
