Santos GLNG Marine Crossing

The Santos GLNG Project sources gas from Santos’ gas fields in the Surat and Bowen basins. The gas is transported via a 420-km underground pipeline to a two-train LNG plant with a nameplate capacity of 7.8 million tonnes per annum on Curtis Island, Gladstone. GLNG is a joint venture between Santos and three of the world’s largest LNG companies, PETRONAS, Total and KOGAS.

The marine crossing project comprised of a 4.3km tunnel connecting Curtis Island to the mainland. A Tunnel Boring Machine (TBM) was utilised for the excavation which launched on April 2013. The diameter of the tunnel is 3.4m, with conventional segmental lining methodology applied. Once the tunnel is complete, the tunnel will be flooded, the pipe strings will be joined together and installed in the tunnel.
