Woodside Petroleum has pushed back its schedule for the Browse FLNG (Floating Liquefied Natural Gas) project as it looks to take advantage of lower costs.
The company said a revised schedule had been agreed.
Woodside has already completed basis of design and key preparation work for the proposed development.
The North West Shelf (NWS) operator Woodside Petroleum and its partners have approved the $1.2billion Persephone project.
It is the third major gas development for the NWS project, which is off the north-west coast of Australia.
The project will involve a two well, 7km subsea tieback from the Persephone field to the existing North Rankin complex.
