Oil major Chevron is planning to decommission a number of installations offshore Australia.
The company said the move is in response to the oil price decline.
It includes a number of installations at the Saladin, Cowle, Crest, Roller and Skate fields.
Chevron plans to use a jack-up and construction vessel with a crane for the offshore work and a workover rig for the task of plugging the wells.
Work is anticipated to begin in 2016 and take about 12 months to complete.
