ATCO has signed an agreement with Bechtel to design, manufacture, transport and install 357 modular units for the Chevron-operated project in Western Australia.

The under-construction Wheatstone LNG project is located at Ashburton North, 12km west of Onslow, and will have a capacity of 15 million tons per annum (MTPA).

At the first stage, the plant will have two LNG trains, with a capacity of 4.3MTPA each, and a gas plant.

The gas will be supplied from the Wheatstone, Iago, Julimar, and Brunello offshore gas fields.

ATCO’s units will be used to form a variety of office complexes and free standing modular buildings on site, including training centres, IT buildings, guardhouses and medical centres.

The company is expected to begin work in July 2013 and complete the manufacturing work in the second quarter of 2014.

The LNG plant is expected to become operational in September 2013 and will supply about 60% of the required units for the Wheatstone Project.

The Wheatstone Project is a joint venture, which includes Australian subsidiaries of Chevron, Apache, Kuwait Foreign Petroleum Exploration Company, Shell, Kyushu Electric Power Company with 64.14%, 13%, 7%, 6.4%, and 1.46% interest, respectively, while PE Wheatstone holds 8%.
