A helicopter has ditched in the North Sea off the coast of the Netherlands, but all 17 people on board have been pulled safely from the water.
The incident happened at midnight (2300 GMT) about 25km (15 miles) from the port of Den Helder, north of Amsterdam.
The Super Puma, carrying four crew and 13 oil platform workers, developed engine trouble, the coast guard said.
Most of the survivors were put onto a rescue boat. One was flown to hospital with hypothermia.
The helicopter was carrying workers from a North Sea oil platform that had suffered power failure, coast guard official Frank de Ridder said.
