Chevron Australia Pty Ltd has announced it expects the repairs to the heat exchangers at LNG Train 2 at the Gorgon plant site on Barrow Island off the north-west coast of Western Australia will be finalised and allow for the restart of production at Train 2 in October 2020.
The weld quality issues were discovered during scheduled maintenance in July 2020. Following ongoing technical work, Chevron says that it will be ‘further refining’ its approach and has decided some welds in targeted areas will require additional work.
Chevron has discussed its plans with the regulator and will maintain alignment on its requirements for inspections and repairs on the Gorgon heat exchangers and the sequencing of work on Gorgon Trains 1 and 3.
“Insights gained from the Train 2 repairs will contribute to more efficient inspections and potential repairs on Trains 1 and 3,” the company said on Thursday.
“Chevron and the regulator share the same goal of maintaining the safety of our workforce and operating facilities.”
“We continue to provide natural gas to the Western Australian domestic market and LNG to customers under our contractual commitments.”
