BBC News - Survivor tells of Super Puma crash ahead of CAA Norway talks
Mr Nugent told BBC Scotland: "There was a hell of a noise and twisting in the fuselage.
"We realised there was something really wrong with the helicopter.
"About four seconds later we were hitting the surface of the water hard. Water was rushing into the fuselage. We had crashed."
He said he managed to escape after trying to help colleagues, but was now struggling to go near helicopters.
