Woodside has planned major maintenance at its 4.9 million-tonnes-per-annum Pluto LNG facility for about one month from April to May, a company spokeswoman said on Wednesday.

It has also planned major maintenance at its North West Shelf project's Goodwyn A platform train 2 for 21 days and LNG train 1 for 19 days, both in July, she said.

An integrated North West Shelf project maintenance is also planned for September, including major work on LNG train 5 for 19 days, fractionation for 14 days, North Rankin Complex for 19 days and North Rankin train 2 for 20 days, she said.

Separately, Chevron said it has planned work at its Gorgon LNG facility from May 23 to July 9 that will involve the shutdown of a little more than half a train.

The three-train Gorgon project, one of the world's largest natural gas projects, can produce 15.6 million tonnes of LNG annually from its three trains, according to Chevron's website.
