Scope of work

JPS was engaged by Chevron Australia to apply their extensive LNG experience in an Integrated Operational Support capacity. This Integrated approach allowed Chevron to take advantage of JPS’s unique skill set and extensive multi-asset experience for the duration of the Train 2 2022 Major Turnaround event, which also included Inlet and Domestic Gas Facility major maintenance.
JPS resources were directly integrated into the WSLNG Operations team to help de-risk and provide certainty of outcome for the scheduled scope of work. This integration model helped ensure the safe and timely restart of the asset, the timely completion of the defined workscope and the safe return to service of Train 2 and DomGas.

Facility Overview

The Wheatstone LNG asset is one of Australia’s largest LNG Facilities. The onshore facility is located in the Ashburton North Strategic Industrial Area, 7.4 miles (12 km) west of Onslow in Western Australia’s Pilbara region.
The asset is made up of two liquefied natural gas (LNG) trains with a combined capacity of 8.9 million metric tons per annum and a domestic gas plant.
Chevron also owns and operates the Wheatstone Platform, the largest offshore gas-processing platform ever installed in Australia, with a topside weight of about 37,000 metric tons.
