THE $20 billion Gladstone LNG project has now passed its 80% mark, with the enormous facility on Curtis Island on track to start pumping out its liquid gas next year with the budget still intact.
Gas powerhouse Santos has a 30% stake in the undertaking, which has been under construction since January 2011.
Beyond the plants that convert coal seam gas to liquefied natural gas, Santos and co-owners Petronas, Total and Kogas are developing gas wells in the Bowen and Surat basins.
A 420km pipeline funnels CSG from the gas fields to the Curtis Island plant.
According to the latest Santos quarterly report, the pipeline is now 85% finished, with almost half the underground tunnels already tested.
The 4.3km marine crossing tunnel and pipeline under Gladstone Harbour, linking the mainland to the island facilities, has also been finished.
The GLNG project is just one of three on the Curtis Island site.
The Australia Pacific LNG project from Origin is also understood be on schedule and budget, according to an update released late last year.
The Queensland Curtis LNG development from BG Group is understood to be ahead of its competitors, with its plant to be commissioned in the first half of this year.
All three of the sprawling gas sites are being built by construction firm Bechtel.
