An oil platform is believed to have broken free of its anchor. The platform is thought to be a semi-submersible type and is situated to the north east of Shetland.
It is believed to have broken its anchor chain on Wednesday evening and production has been shut down by the operators as a precaution. A backup anchor is still in place.
There is an estimated 50 people on board the platform which produces around 27,000 barrels of oil a day, they are not thought to be at risk.
Newsnet Scotland has contacted the operators to seek further information and clarification.
