CB&I was awarded a contract from Woodside Energy Limited for the North West Shelf Venture onshore gas plant near Karratha, Western Australia. The Woodside operated, North West Shelf Venture facility is located on the Burrup Peninsula near Karratha in Western Australia about 1260km north of Perth.
CB&I’s work scope included the mechanical erection for the Phase V liquefied natural gas (LNG) production train that has a design capacity of 4.4 million tonnes per annum (TPA). The Phase V expansion increased the plant's capacity to 16.3 million TPA, making it one of the largest LNG complexes in the Asia-Pacific region. CB&I was previously responsible for mechanical erection of the plant's LNG Train IV (ie 4) Project.
CB&I's work included the installation and connection of modular LNG units, as well as structural, mechanical, and piping works installation. CB&I’s portion of the project included the LNG train, fractionation unit, power generation unit, topsides for the jetty extension and interconnecting pipe racks, and the fuel gas and boil off gas systems. Up to 1,800 people were employed at Karratha during the peak of construction.
The LNG Phase V Expansion project is a world-first for modular construction.. There are a total of 75 modules with a combined weight of 17,500 tonnes.
The biggest Phase V module is the main liquefaction unit, which is approximately 1920 tonnes and 35 meters in height.
