GLNG Pipeline nearing completion after successfully crossing the Gladstone Harbour

The 120 pipeline segments, each measuring 36 m, were welded and pushed through the 4.3 km tunnel over the past month using a large hydraulic jack, as the tunnel filled with seawater to buoy the 1,066.8 mm diameter pipeline.

Santos Vice President Downstream GLNG Rod Duke said the delivery of the first under-sea crossing for Queensland’s CSG-to-LNG industry brings the pipeline to its final stages of completion.

The GLNG Project involves the development of gas fields in the Bowen and Surat basins, the construction of a 420 km underground gas transmission pipeline, and a two-train LNG processing facility on Curtis Island at Gladstone.
