Woodside Petroleum successfully restarted production Friday at its Pluto LNG Plant in Western Australia.

The Pluto plant was shut in Monday after the Atwood Osprey drilling rig, under contract to another company, was torn from its moorings by a cyclone and drifted dangerously close to Pluto’s flowlines.

The Atwood Osprey rig was drilling at Chevron’s nearby Wheatsone LNG project and had been shut down and secured because of tropical cyclone Olwyn.

The rig, owned by Houston-based Atwood Oceanics, suffered minimal damage but will be unable to work for up to 30 days.

An underwater inspection confirmed that flowlines at the $11 billion Pluto project were not damaged.

No injuries or environmental damage were reported.

The plant’s 2015 production target range of 84 to 91 million barrels of oil equivalent remains unchanged, Australia-based Woodside Petroleum said.

The Pluto field, located in the Carnarvon Basin off the coast of Western Australia, is projected to account for 38 percent of Woodside’s 2015 production.

​Woodside operates Pluto with a 90 percent stake.

Japan-based Tokyo Gas and Kansai Electric each hold 5 percent stakes.
