Leighton Holdings’ subsidiaries Thiess and John Holland Group have been awarded $300 million in contracts for the Chevron-operated Wheatstone gas project near Onslow.
John Holland has won a $240 million contract to design and construct 12 permanent buildings for the onshore gas processing facilities, including an operations building, laboratory, maintenance centre, vehicle maintenance shop, fire station and plant warehouse.
The contract is the second Wheatstone development for John Holland, with a $370 million accommodation design and construction contract awarded to the company earlier this month.
John Holland western region general manager Adam Harry said the timing of the Wheatstone permanent buildings will enable John Holland to deliver additional benefits to Chevron.
"There are synergies to be gained by the concurrent delivery of the accommodation village and permanent buildings on Wheatstone, as well as work on non-process infrastructure on the Gorgon project," he said.
"We will be looking to move people from our Gorgon contract, which has similarities to the permanent buildings work, and tap into this experience on Wheatstone."
Thiess was awarded a $60 million contract to construct a 1.2 kilometre long tunnelled shore crossing under the ocean while will connect two offshore gas reserves with Chevron’s greenfield LNG plant at Ashburton North.
Thiess general manager Bruce Munro said the company had already had a major role with Chevron in the Gorgon LNG project, and it was delighted to continue its participation in the LNG industry.
The company said engineering and procurement will commence immediately for the design of the project, with construction on site to begin after the cyclone season in 2013.
The Wheatstone project is one of Australia’s largest resource projects, with the initial phase liquefied natural gas capacity expected to be 8.9 million tonnes per annum.
