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
- Chevron Australia needed an EPCM partner 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. As operator of the project, Chevron Australia implemented a comprehensive quarantine management system to protect the island’s ecology, which Hatch adhered to.
- The project's downstream scope focused on three 5.2 Mtpa LNG processing trains, the LNG storage facility, jetty, a domestic gas plant, and a utilities and materials offloading facility.
Solutions
- Worked as part of the Kellogg Joint Venture Gorgon to complete the front-end engineering and design phase through to fabrication, construction, and execution of the project’s downstream facilities.
- 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 eight countries in 15 locations.
