The contract covers both the Gorgon and Jansz fields which are 65 kilometres and 130km off Barrow Island in water depths of up to 1350 metres.

Project management and engineering is to begin straight away with offshore operations set to kick off in 2013.

The Gorgon LNG project is being built to develop the Great Gorgon gas fields off the north-west coast of Western Australia which are estimated to contain about 40 trillion cubic feet of gas.

Gorgon’s first phase of development comprises of three liquefaction trains with total capacity of 15 million tonnes per annum which Chevron is targeting to come onstream in 2014.
