More than 200 workers evacuated from drilling platform as vessel breaks moorings in stormy seas and floats towards Valhall oilfield
Hundreds of oil workers have been evacuated from North Sea drilling platforms after an unmanned barge was cut adrift by storms.
BP ordered more than 230 staff to leave the Valhall field in Norwegian waters after the huge barge broke its moorings and threatened to crash into platforms which produce around 50,000 barrels of oil a day.
