Darwin LNG Plant Shutdown Triggered by Middle East Supply Crisis

The Darwin LNG plant shutdown has been temporarily initiated by Santos at its facility in Australia’s Northern Territory (NT), according to a report from Reuters. This halt has interrupted exports from a recently revitalized supply chain, even as the demand for LNG continues to remain strong, especially amid ongoing disruptions in Middle Eastern supply. Santos clarified that the shutdown is linked to equipment replacement work for the BW Opal floating production vessel, part of the Barossa gas and condensate project located in the Timor Sea. This project is essential as it provides gas for the Darwin plant.

A spokesperson for Santos stated that this shutdown was planned and involved commissioning procedures, but a timeline for the resumption of operations was not provided. The Australian Financial Review highlighted that a stakeholder update from Santos, which was reviewed by industry outlet Boiling Cold, indicated that the Darwin LNG plant could be offline for several weeks. The spokesperson added, "We are in the final stages of commissioning for Barossa LNG to flush the system before coming back on and getting back to full rates."

Earlier this year, Darwin LNG had resumed exports following delays caused by technical issues at Barossa, including compressor seal faults that affected production. In a quarterly production report released in January 2026, Santos projected total production for the year to be between 101 and 111 million barrels of oil equivalent (mboe), with Barossa expected to contribute approximately 19 million barrels (mbbl). Santos maintains a 50% operating interest in Barossa, with SK E&S holding 37.5% and JERA owning the remaining 12.5%.

Since commencing operations in 2006, Darwin LNG has been processing Bayu-Undan gas from offshore Timor-Leste until mid-2025, when the field is anticipated to reach the end of its life. Santos took over the operation of Darwin LNG in 2020 after acquiring ConocoPhillips’ Australia West assets. Currently, the facility operates under a Major Hazard Facility license, which includes a Safety Case approved by NT WorkSafe and an NT EPA Environment Protection License.

In a related development, Santos and its joint venture partner Beach Energy recently made a final investment decision for the Moomba Central Optimisation project located in South Australia’s Cooper Basin. With ongoing Middle East supply disruptions affecting the market, the timing of the Darwin LNG plant shutdown raises critical questions about future supply continuity and the stability of the LNG market.
