The Queensland Curtis LNG Project
QGC is developing coal seam gas in the Surat Basin of southern Queensland for domestic and export markets through its Queensland Curtis LNG (QCLNG) Project.

QCLNG involves dozens of communities, hundreds of businesses and thousands of people drawn from throughout the state, the rest of Australia and internationally. Our plans for this major, integrated 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.

In 2010 Thiess were awarded the early work package for the site preparation works for the Curtis Island plant, these works included bulk earthworks, pad preparation and construction and haul roads.

The contract was a fixed price contract with tight timeframes for delivery and staged handovers to allow accelerated plant construction.
