Subsea 7 has bagged the award worth around $440 million which will see it install and tie-off heavy-list structures on the project off the west of the country. The project involves 20 subsea structures and foundations, 15 heavy spools, 48 tie-in spools and numerous electrical and hydraulic leads as well as umbilicals.
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.
In mid July Chevron handed Subsea 7 an $80 million subsea umbilicals contract for work at Gorgon and Jansz fields.
The Gorgon and Jansz umbilicals, which are 59 kilometres and 135 kilometres in length repectively, will be transported from Europe using the Seven Seas flexible pipelay vessel.
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.
Chevron holds a 47% stake in the project along with ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%),Tokyo Gas (1%) and Chubu Electric Power (0.417%).
