Santos said this is a significant milestone for the multibillion-dollar project as the tunnel will encase the 420 km, 910 mm diameter underground gas transmission pipeline linking the mainland to the LNG plant on Curtis Island.

Santos GLNG Pipeline Manager Greg Jones said “A team of twelve people worked for around six weeks to assemble a 100 m long and 277 t tunnel boring machine onsite, which will be used by Thiess to excavate through rock and soil and install the concrete tunnel lining.
