Chevron to restart 2nd Gorgon LNG train in September
Chevron is looking to place back online the second train at its Gorgon LNG plant in Australia in September after it found “weld quality issues” within the propane heat exchangers.
The US energy firm shut down the second production unit at its giant 15.6 mtpa LNG facility on Barrow Island in Western Australia on May 23 as part of planned maintenance.
It aimed to complete the maintenance works and restart the unit on July 11.
A Chevron spokesperson said in emailed comments on Tuesday that the company completed all the work but the train is still offline.
“A routine inspection of the Gorgon LNG Train 2 propane heat exchangers identified weld quality issues,” he said, adding that the unit has in total eighth exchangers.
“Repairs are underway and we have the necessary personnel with skills and knowledge to conduct the work onsite,” the spokesperson said.
Chevron is working with the regulator, the Department of Mines, Industry Regulation and Safety, in planning and implementing this work.
“Once repairs are complete, we expect to safely commence LNG Train 2 restart activities around early September,” the spokesperson said.
In the meantime, Gorgon trains one and three are continuing to produce LNG.
The spokesperson added that Chevron continues to deliver LNG and domestic gas under its contractual commitments with customers.
