DoT Maritime Executive Director Chris Mather said vessels at Port Walcott, Barrow Island, Onslow, and Cape Preston had been told to implement their cyclone contingency plans and move to their dedicated cyclone mooring or pen.
“Vessels without these arrangements have been instructed to leave the facilities and vessel access to these waters is now not available,” Mr Mather said.
“These actions have been undertaken in close consultation with facility operators and DoT continues to work to minimise the impact of the severe weather over the coming days.”
Mr Mather said weather forecasts would be monitored and once conditions improved vessels would be allowed to enter the facilities again.
He said operators could contact the DoT Harbour Master to discuss any safety or operational concerns.
