The North-West Shelf joint venture is set to carry out maintenance work this month at the Karratha gas plant in Western Australia.

North-West Shelf operator Woodside Petroleum revealed maintenance work will start on an unspecified train at the facility on 26 July and is scheduled for completion on 13 August.

Another maintenance window is planned between 5 September and 1 October, which will see work carried out on multiple trains at the liquefied natural gas facility.
