Santos has announced that the GLNG’s tunnel boring machine is powering to the finish line with only 600 metres to go before it breaks through to the surface at Curtis Island, Gladstone.

With the lion’s share of boring now complete, the reception pad is ready to receive the 277-tonne machine that began its journey under The Narrows in April.

Part of Santos GLNG’s 420 kilometre pipeline will be encased in the tunnel, connecting gas hubs on the mainland to the liquefied natural gas plant on the Island.

Concrete-coated steel pipes are currently stored at Marine Crossing, ready to be pulled into the passage once it is finished.

A pump to remove water was installed in the deepest part of the tunnel during November.
