Project Profile
Value: US$20.4 billion
Location: Curtis Island, near Gladstone, Australia
Start-up Year: 2014
LNG: 8.5 million tonne/year
The plans for the project involve:
- Expanding QGC’s existing coal seam gas production in the Surat Basin of southern Queensland
- Building a 540km buried natural gas pipeline network linking the gas fields to Gladstone
- Constructing a natural gas liquefaction plant on Curtis Island, near Gladstone, where the gas will be converted to LNG for export
The project’s first stage will comprise two processing units, known as LNG trains, at the Curtis Island plant. These trains, which have a design life of at least 20 years, will produce a combined 8.5 million tonnes of LNG a year.The site can accommodate an expansion to 12 million tonnes of LNG a year, subject to demand. Construction is scheduled to begin in 2010, with the first LNG delivery expected in 2014. The proposed LNG plant will occupy less than 1% of Curtis Island and will be separated from public areas by an environmental protection zone.
