Australian unions claim “thousands of cracks” have been found on the propane kettles at one of the trains on Chevron’s Gorgon liquefied natural gas project in Western Australia.

The Australian Manufacturing Workers' Union (AMWU) is calling for the US$54 billion project to be temporarily shut down after cracks were found in eight of the pressurised propane kettles during a maintenance turnaround on Train 2.

According to the AMWU, some of the discovered cracks are up to one-metre long and 30 millimetres deep and it has called for Chevron to shut down the remaining two trains at Gorgon for for inspection.
