Rescuers are searching for the missing crew members of a large commercial vessel after it capsized off the US state of Louisiana.
There were reportedly 18 people on board, and on Wednesday the US Coast Guard said it had so far rescued six.
The 129ft (39m) lift boat capsized about eight miles (12km) from Port Fourchon on Tuesday afternoon.
A spokesman for marine transportation company Seacor Marine later identified the vessel as belonging to the firm.
A lift boat is a self-propelled vessel with an open deck, often using legs and jacks, and is deployed to support drilling or exploration.
Seacor spokesman Armond Batiste told the New York Times that the ship was the Seacor Power.
In a statement, the US Coast Guard said it had received an emergency radio notification at 16:30 (21:30 GMT) that there was a distressed commercial vessel about eight miles from the coast.
It said an "urgent marine information broadcast" had been issued which "multiple good Samaritan boat crews responded to".
