Barrow Island

13 trillion cubic meters (13,000,000,000,000m3) – these were the natural gas resources of the Greater Gorgon Gas Field according to 2009 estimates. The largest resource project in the world, located off Barrow Island on the northern coast of Western Australia in the Indian Ocean can cover almost one tenth of worldwide demand per year for Liquified Natural Gas (LNG). The overall project includes an offshore system of pipelines and industrial natural gas exploration plants as well as the onshore gas liquefaction plants on Barrow Island.

Supported by a Pipe Thruster, two Herrenknecht HDD Rigs drilled a total of nine landing drills with lengths between 450 and 520 meters and diameters of eight to 34 inches. The drills form one part of the link between the offshore terminals and the onshore plants on Barrow Island. The installed pipelines cross safely beneath the ecologically sensitive coastal strip, complying with the strict environmental regulations of the Australian government.
