Chevron has temporarily suspended production from one of the three large liquefied natural gas trains at the Gorgon project in Australia following a minor gas leak at the facility.

The company said that during routine operator duties a small leak was detected on piping associated with the dehydration unit on Gorgon Train 1.

The Gorgon project has three trains with combined LNG capacity of 15.6 million tonnes per annum.

"As a precautionary measure, Train 1 was shut down in a controlled manner to isolate the area where the leak was identified. We are preparing plans for investigation and repair," said a company spokesperson.

"Appropriate safety measures are in place to keep our workforce safe. As part of routine site engagements, the regulator — DMIRS — is currently visiting Gorgon and has been notified."

The other two trains at Gorgon remain operational "and we continue to deliver LNG to customers and natural gas to the Western Australian domestic market", said the spokesperson.

Gorgon is Australia's second-largest LNG project in terms of design production capacity; just behind the North West Shelf LNG project.

Gorgon LNG shipments were steady in October 2021, with 21 cargoes shipped, the same as in September, according to the Australian analyst EnergyQuest.

LNG production at Gorgon in October was 16.9 million tpa on an annualised basis, 108% of nameplate capacity.
