Australia’s National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) has sent back Chevron Australia Pty. Ltd.’s start-up and operations environment plan for the Wheatstone domestic gas-LNG project off Western Australia saying the plan is not sufficiently robust.
The plan includes the offshore platform at Wheatstone, its subsea facilities, and the subsea pipeline to the gas and LNG plant at Ashburton North near Onslow.
NOPSEMA says Chevron has not outlined an appropriate implementation strategy, including monitoring, recording and reporting arrangements, for bringing the offshore facilities on stream.
The federal regulator says the proposal was not appropriate for the nature and scale of start-up of the project, which lies 50 km from the Montebello Islands National Park and Barrow Island (a Class A reserve). It added that the proposal did not demonstrate that the environmental risks of the start-up will be reduced to as low as reasonably practicable.
The offshore Wheatstone facilities will produce, gather, and dewater the field’s hydrocarbons before sending the dry gas and condensate via pipeline to the shore plant.
