GLNG plant

The GLNG plant is located on Curtis Island approximately five kilometres north of the city of Gladstone, Queensland.

Construction commenced on the LNG Plant in 2011 with the first cargo in October 2015.  

The LNG plant consists of two trains. These trains have a combined nameplate capacity of 7.8 million tonnes per annum, and act like a refrigerator, cooling the natural gas down to -161°C.  At this temperature the gas becomes a liquid, at just slightly over atmospheric pressure.  Prior to this cooling process, carbon dioxide and water are removed from the natural gas.  

Following this process, the liquified natural gas is then pumped into large, insulated storage tanks where it is stored at atmospheric pressure until loading onto large insulated LNG ships for export.

The LNG Plant employs the Optimised Cascade LNG Process licensed from ConocoPhillips.

The LNG Plant Facility is classified as a Major Hazard Facility due to the large inventory of flammable hydrocarbon products stored and processed on the site. Due to the Facility being a Major Hazard Facility, a safety case was developed and approved by the regulator. 


GLNG utilises the Santos Management System to support the safe and reliable operation of the LNG facility.
