Operations at Gorgon LNG Train 1 in Western Australia restarted this week after a month-long outage.

Chevron told Reuters on Wednesday that operations at Gorgon LNG Train 1 “resumed earlier this week” after being temporarily halted in late November.

Chevron said at the end of November that it paused production at Train 1 to “assess some recent performance variations.”

Chevron told Reuters on Wednesday that production at Train 1 was halted so that the company could “assess and address some performance variations.”

The company has not disclosed further details about the performance variations it was assessing.

Output at Gorgon’s Train 2 was unaffected by the outage.

Chevron said when Train 1 was halted that it continued to produce LNG and load cargoes at Gorgon.

Production at Gorgon has been halted several times since operations began in March.

Exports from Gorgon were temporarily halted about one month after production began due to mechanical issues with the propane refrigerant circuit on Train 1.

In July, a gas leak forced Chevron to temporarily halt production at Gorgon.

Chevron was still able to export its second cargo from the facility despite the July gas leak.

Production at Gorgon’s Train 1 was briefly halted in early November for minor maintenance work.

The November outage did not impact the ramp up of Gorgon’s Train 2.

The project is supplied from the Gorgon and Jansz-Io gas fields, located within the Greater Gorgon area, between 80 miles and 136 miles off the northwest coast of Western Australia.

The project is operated by Chevron Australia with a 47.3 percent stake.
