WOODSIDE Energy has selected preferred contractors for integrated maintenance services on its North West Shelf assets.
The preferred contractors for the assets have been split along oil and gas lines with Woodside selecting a Clough-AMEC joint venture to handle the oil operations, while the Transfield Services and WorleyParsons joint venture (Transfield-Worley) will continue to look after the gas assets.
Transfield-Worley has been providing capital works programs and maintenance services for the North West Shelf for the past 10 years, but this is the first time the oil assets have been tendered away from the Transfield-Worley venture.
The Woodside integrated services contracts involve the supply of project management, integrated engineering, operational maintenance, and modification and supply chain integration services to Woodside.
Clough expects the tender process to be complete by September, while WorleyParsons anticipates completion of its agreement by the end of June.
AMEC’s local engineering and construction businesses were bought by east coast outfit Leighton Holdings in March, however the oil and gas division, which has its office in Perth, has remained a part of the UK-based AMEC International.
The Clough-AMEC operation is an equal partnership between the two companies.
Woodside also recently signed a letter of intent for engineering, procurement and construction management for the phase five expansion with US engineering and construction company Foster Wheeler and Sydney-based WorleyParsons.
Final approval for the $2 billion project is planned for the first half of this year to ensure a fourth quarter 2008 start-up, but this is subject to progress with LNG marketing and individual participant board approvals of the scope of the project within the joint venture.
The phase five project scope includes the design, construction and commissioning of a fifth LNG processing train, with capacity of 4.2 million tonnes per year, together with other related expansion work at Woodside’s onshore gas plant at Karratha.
The award of Clough-AMEC as preferred tenderer for services follows existing services work it is performing for ConocoPhillips on the Bayu Undan platforms in Indonesia as well as an offshore installation contract.
Clough was also issued a letter of authorisation in January to perform pre-feed work for the Gorgon Downstream LNG project.
Clough believes further growth opportunities may flow from Woodside’s new facilities as production commences.
