Leg amputated after Happy Buccaneer accident

One of the workers injured aboard a heavy lift ship on Monday has undergone leg amputation.

The 55 year-old Portuguese sailor suffered a crush injury when a spreader beam fell during work aboard Netherlands registered heavy lift vessel Happy Buccaneer.

A Filipino man also suffered compound fractures to his leg and a broken pelvis, according to The West Australian.

The two men were treated by Roy Hill emergency response team members, who responded immediately to the emergency.

Both men were later flown to Perth by the Royal Flying Doctor Service.

A spokesperson for Roy Hill said the ship was moored at the Stanley Port at the Roy Hill South West Wharf construction project, and had been unloading modules or equipment.

The spokesperson said the ship had finished unloading goods for the Roy Hill site and was preparing to leave the port.

"It happened on a vessel that was moored at the Roy Hill wharf, but it's not our incident, it didn't happen on our project," the spokesperson said.

The incident is under investigation by Australian Maritime Safety Authority.

The Pilbara Port Authority said the accident did not affect port operations.
