Four injured in US oil rig blast
An explosion and fire has ripped through a Gulf oil platform in the US as workers used a cutting torch, sending four people to a hospital with burns and leaving two missing in the sea off Louisiana.
Coastguard Captain Ed Cubanski told a news conference in New Orleans the well was not producing at the time and no oil was leaking.
A small amount of oil spilled from the rig when workers using a torch cut into a 75ft long, three-inch wide line on the platform. Captain Cubanski said a sheen half a mile long and 200 yards wide was reported in the area.
"It's not going to be an uncontrolled discharge from everything we're getting right now," Mr Cubanski said.
The fire had since been extinguished, said Coastguard spokesman Drake Fore. He said Coastguard aircraft and boats were searching for two missing people but nobody was believed killed in the fire.
The platform is for oil production from an established well, unlike the Deepwater Horizon rig, which was drilling an exploratory well for oil giant BP in mile-deep water when it blew up and triggered a massive oil spill in 2010.
Taslin Alfonzo, spokeswoman for West Jefferson Medical Centre in suburban New Orleans, said four injured workers were brought to the hospital in critical condition with second and third-degree burns over much of their bodies. Three arrived by helicopter at 9.55am local time and one by helicopter at 10.10am.
Two were sent by ambulance to the Baton Rouge Burn Centre. Two others were to be sent later. She could not release identities or any other information.
The production platform owned by Black Elk Energy is about 25 miles south east of Grand Isle, Louisiana. The Coastguard said 26 people were aboard at the time of the explosion.
Captain Cubanski said the platform appeared to be structurally sound. After the April 2010 explosion on the Deepwater Horizon, that rig burned for about 36 hours before suffering structural collapse and sinking to the Gulf floor. The Black Elk platform is in 56ft of water. Captain Cubanski said 28 gallons of oil were in the broken line.
