Four of Australia's big liquefied natural gas proponents have been authorised to co-ordinate maintenance activities at their LNG facilities in Western Australia and Northern Territory, writes Russell Searancke.

The four — Woodside, Chevron, Shell and Inpex — will compete for a limited pool of skilled contractors and specialised equipment to conduct scheduled maintenance.

However, the Australian Competition and Consumer Commission (ACCC) has ruled they will now be able to schedule their maintenance together, reducing concurrent work at their facilities, and thereby improving efficiency and maximising LNG production.
