NSW crewman crushed off WA's coast

A crew member killed from injuries he received on board a supply vessel off Western Australia's Pilbara coast was a father of four from New South Wales.

Andrew Kelly, 39, was crushed between two containers while trying to secure cargo in rough weather on the Skandi Pacific.

He was taken to a nearby drill platform for medical assistance but died of his injuries on Tuesday.

The Australian Transport Safety Bureau is investigating the fatal incident.

Mr Kelly leaves behind a wife and four children, all aged under 10, the youngest of whom is less than six months old.

The Maritime Union of Australia national secretary Paddy Crumlin said the tragedy was a timely reminder of the dangers workers in the offshore industry faced.

"My and all the MUA's thoughts are with the Kelly family in particular, along with his workmates on this unfortunate day," Mr Crumlin said.
