The Gorgon Project will develop the Gorgon and Jansz/Io gas fields, which are located approximately 130 km off the northwest coast of WA.
It includes the construction of a three-train, 15 MMt/a LNG plant on Barrow Island, and a domestic gas plant with the capacity to supply 300 TJ/d of gas to the WA market.
LNG will be shipped to international markets, while compressed domestic gas will be delivered via a 90 km, 508 mm diameter subsea pipeline to the WA mainland, interconnecting with the Dampier to Bunbury Natural Gas Pipeline.
KT, a subsidiary of engineering group Monadelphous, will install and pre-commission 7 km of underground pipeline, five well sites and associated facilities as part of a CO2 injection initiative.Article continues below…
According to KT, the Gorgon injection project is one of the world’s largest emissions abatement initiatives, and will potentially position Australia as a world leader in this technology. The project will also generate a significant number of local jobs.
The CO2 injection facility is expected to reduce the project’s overall greenhouse gas emissions by approximately 40 per cent per year. Naturally occurring CO2 will be extracted from the natural gas during processing and injected into the Dupuy Formation more than 2 km below the island.
The CO2 injection, combined with best practice in plant design, will make Gorgon one of the world’s most greenhouse gas efficient projects, says KT.
Works commenced in December 2011 and is scheduled to be completed in 2013.
The contract aligns with KT and Monadelphous’ commitment to minimise the group’s carbon footprint. The group is offsetting its carbon emissions for 2011–12 through the Climate Friendly program.
KT is part of Monadelphous’ infrastructure division, which was established in July 2010 as part of the company’s diversification strategy to continue to support long-term growth.
This is the third pipeline contract that KT has secured on the Gorgon Project. It follows contracts for the installation of pipelines, cables and tubes for Chevron Australia and the construction of the onshore domestic gas pipeline for the Clough Sea Trucks Joint Venture.
The contract is part of more than $1.5 billion of new work secured by Monadelphous so far this financial year.
The Gorgon Project is a joint venture between the Australian subsidiaries of Chevron (approximately 47 per cent, as operator), ExxonMobil (25 per cent), Shell (25 per cent), Osaka Gas (1.25 per cent), Tokyo Gas (1 per cent) and Chubu Electric Power (0.417 per cent).
