Leighton Contractors has been awarded a contract by Chevron Australia to deliver the civil and underground works package for the Gorgon Project valued at more than $800 million, the company said in an issued statement today.

This contract will compliment Leighton current work in hand at the Gorgon Project where the company is completing works on the 2.1 kilometre LNG jetty and marine structures in consortium with Saipem worth $1.1 billion dollars.

The team will commence work immediately and are expected to be complete by mid 2013.

The Gorgon Project is operated by an Australian subsidiary of Chevron and is a joint venture of the Australian subsidiaries of Chevron (approximately 47 per cent), ExxonMobil (25 per cent) and Shell (25 per cent), Osaka Gas (1.25 per cent), Tokyo Gas (one per cent) and Chubu Electric Power (0.417 per cent).

Craig Laslett, Managing Director for Leighton Contractors, said in a statement: "We have a genuine commitment to deliver the project with the highest standard of safety and to provide the expertise and services required to develop Australia's energy needs in line with sustainable economic development," he said.

Ray Sputore, General Manager of Leighton Contractors Western Region, said: "Leighton Contractors has strong experience working with oil and gas clients, and a skilled team to ensure our contribution is world-class."

"Being the largest single resources project in Australia, we will be drawing on our pool of skilled workers as well as new talent to meet the peak target of 1,500 employees across both Leighton contracts."
