Chevron’s Gorgon LNG project has resumed operations, nearly two months after stopping production.
Its cargo is expected to depart from Barrow Island to Gorgon part-owner Royal Dutch Shell at the end of May.
The operation halted production in April due to the repair of one of its propane refrigerants and expected to restart activities within 30 and 60 days.
There is speculation that the breakdown was caused by a hurry to finish construction of Train 1 and start production in time for the company’s annual investor day in New York on March 8.
Pipe cooling and pre-start activities began yesterday in preparation for production, which involved cleaning natural gas from offshore fields before chilling it to -162°C to turn it into a liquid.
Chevron will not discuss the schedule for the restart or indicate the repair bill to fix the broken propane refrigerant circuit on the operation’s first LNG processing train; however past estimates have been declared at up to $200 million.
A Chevron spokeswoman said, “Start-up activities are under way on Gorgon Train 1 with a plan to safely resume production in the coming weeks,” according to Yahoo7 News.
“Construction activities continue to progress on Trains 2 and 3, with timing not affected by work on Train 1. Repairs on the train one propane refrigerant circuit are complete.”
Train 1 had increased production to a run rate of 3.5million tonnes of LNG per year and despite repeated delays, Chevron maintains that all three trains can be increased at three month intervals.
