Gas export pipeline
The Ichthys LNG Project’s 890 kilometre gas export pipeline (GEP) will deliver gas and some condensate from the central processing facility (CPF) in the Browse Basin to onshore facilities at Bladin Point near Darwin so that it can be prepared for export.
The lchthys LNG Project GEP will be one of the longest subsea pipelines ever built. The pipeline is 42-inch in diameter and composed of about 700,000 tonnes of steel and coated with 550,000 tonnes of concrete.
International oil and gas contracting service provider Saipem is the engineering, procurement, construction and installation (EPCI) contractor for the GEP.
Saipem’s semisubmersible pipelay barge, SEMAC-1, has installed the 164 kilometre shallow water section of pipe. This work included laying the first 18 kilometre section of the GEP through Darwin Harbour in mid-2014.
Saipem’s state-of-the-art deep water installation vessel, Castorone, lay the remaining 718 kilometres of pipe to the Ichthys Field.
