One energy worker has been killed and three injured after an explosion at a Fieldwood Energy oil and gas drilling platform in the Gulf of Mexico.
The explosion happened about 12 miles off Louisiana's coast just before 3pm on Thursday, 20 November, the Bureau of Safety and Environmental Enforcement said.
The bureau said in a statement that the platform was not in production at the time of the blast and damage was limited to the area, reported the Associated Press.
It added there was no indication that any oil had spilled into the ocean.
A spokeswoman said the injured workers were being treated at a medical facility but did not say where or give details on their conditions.
The explosion is under investigation.
The incident will bring back memories of the Deepwater Horizon oil disaster in the same waters on 20 April, 2010, which killed 11 people and led to an estimated 4.9 million barrels of oil being discharged into the Gulf of Mexico.
