Australia: Gorgon—Country’s Largest Resource Project

Hatch joint venture constructs LNG facility on Barrow Island

The Greater Gorgon gas fields, off the coast of Western Australia, contain an estimated 40 trillion cubic feet of gas. As part of the Kellogg Joint Venture Gorgon (KJVG), Hatch is responsible for engineering and construction of a 15-million-tonne-per-annum (Mtpa) liquefied natural gas (LNG) facility on Barrow Island, which will be linked to the fields by more than 300 kilometres of subsea tiebacks.

KJVG will execute and construct the LNG facility on Barrow Island. The project will consist of three trains producing 5 Mtpa LNG; gas processing and treatment facilities; product storage and offloading; and complete offsites, utilities and accommodations. A modular construction strategy will minimize any potential impact on the island.

The engineering, procurement and construction management contract also includes a 300-terajoule-per-day domestic gas plant. The design of the gas plant will feature reductions of greenhouse gas emissions and improved
waste-heat recovery.

The project, owned by Chevron, ExxonMobil and Shell, will cost more than $43 billion.
