A Northern Territory gas plant has suspended operations after a man died in a workplace accident.
Inpex said the 56-year-old died at its Bladin Point construction site in Darwin about 8pm on Wednesday, forcing work at the $44.7 billion LNG Project to shut down.
"Unfortunately this serious incident resulted in the tragic death of one of our workers," Darwin general manager Sean Kildare said.
Police say the man died at the scene after paramedics tried unsuccessfully to resuscitate him.
"The deceased was working in a confined space installing insulation within a tank when the incident occurred," NT WorkSafe said in a statement.
The Japanese-owned company has informed the man's colleagues and is providing access to counselling.
"Our heartfelt condolences are with the family, friends and the workforce and those involved," Mr Kildare said.
Police and NT WorkSafe are investigating and a file will be prepared for the coroner, while Inpex says it is co-operating fully with relevant authorities.
It comes a week after another worker had a lucky escape when he slipped through scaffolding at the same construction site but was saved by colleagues.
Last Tuesday, the man - who was not wearing a harness - was grabbed by workmates after a railing gave way on one of the 30-metre high tanks, while on November 14 there was a major diesel spill on the main wharf.
In March last year, 500 Inpex workers marched through Darwin to protest against unsafe work practices on site.
