Weld quality issues were discovered during scheduled maintenance in July this year, and the oil and gas producer had initially hoped to restart the train early this month. However, restart production has now been pushed back to October.

“Following our ongoing technical work, we are further refining our approach and have decided some welds in targeted areas will require additional work. We have discussed our 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,” the company said in a statement.

Insights gained from the Train 2 repairs will contribute to more efficient inspections and potential repairs on Trains 1 and 3, the company added.

“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.”
