Gorgon Project

One of the world's largest natural gas projects

Chevron Australia | Australia | 2004–2016

15.6 million tonnes
per year of LNG

300 terajoules
of gas per day domestic gas plant

More than 800
Hatch personnel involved at the peak

240,000 tonnes
of modules and pre-assembled racks

Challenges

  • EPCM, as part of Kellogg Joint Venture Gorgon, for all downstream facilities on the Gorgon Project – one of the world's largest natural gas developments on Barrow Island, 60 km off the coast of Western Australia, which includes three 5.2 million tonnes per annum (Mtpa) LNG trains, a domestic gas plant, and product storage and offloading facilities.
  • Barrow Island is not only a remote location, but also a Class A Nature Reserve. Chevron Australia, operator of the Project, implemented a comprehensive quarantine management system to protect the island’s ecology, which Hatch adhered to.
  • Project’s downstream scope focused on three 5.2 Mtpa LNG processing trains, the LNG storage facility, jetty, a domestic gas plant, utilities and materials offloading facility. 


Solutions

  • Hatch, in joint venture, completed the front-end engineering and design phase through to fabrication, construction and execution of the project’s downstream facilities.
  • We delivered the design, documentation, award and construction management of the major early work contracts and equipment packages.
  • Due to the limited construction footprint on Barrow Island, the Project adopted a modular construction and execution strategy. More than 240,000 tonnes of modules and pre-assembled rack and units were built in fabrication yards in Asia and then shipped to site.


Highlights

  • More than 800 Hatch engineering, technical, and support personnel at the peak working from 8 countries in 15 locations.
