The Gorgon LNG project is facing up to a two month shutdown after mechanical issues halted exports earlier this week.

Chevron said Wednesday that liquefied natural gas (LNG) production at the Gorgon Project has been temporarily halted due to mechanical issues with the propane refrigerant circuit on Train 1 at the plant site.

The propane refrigerant circuit is a closed system used to cool natural gas supplied to the plant.

Repair work is ongoing and the site team is continuing equipment inspection and assessment, Chevron said.

The company said that, based on initial findings, the repair work is “of a routine nature” and all the necessary equipment and material is available on site.

The plant is currently expected to restart within 30 to 60 days, Chevron said.

Exports from the Gorgon project were halted on Monday after the mechanical issue was discovered.

Chevron said the start-up of Train 1 and associated infrastructure is “well advanced” with first LNG production achieved on March 7 and production peaking at nearly 90,000 barrels of oil equivalent per day.

The Gorgon project is located in offshore Western Australia and has a total production capacity of about 2.6 billion cubic feet of natural gas and 20,000 barrels of condensate per day.

The first LNG cargo from the plant departed Barrow Island on March 21 and was delivered to Chubu Electric Power in Japan on Wednesday.

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

ExxonMobil holds a 25 percent stake, Shell holds a 25 percent stake, Osaka Gas holds a 1.25 percent stake, Tokyo Gas holds a 1 percent stake and Chubu Electric Power holds a 0.417 percent stake.
