On Curtis Island north of Brisbane, Australia, there is a modern LNG plant that turns coal seam gas into liquid natural gas (LNG). Coal seam gas is natural gas that is found in underground coal deposits.
On the premises of Australia Pacific LNG, Australia's largest producer of coal seam gas, three LNG tanks were built in which the gas is stored at a temperature of -162°C. The subcontractor STRABAG-DYWIDAG LNG Technology received the design and engineering contract for a total of four 140,000 m³ LNG tanks.
