An offshore operation is under way to secure two linked oil vessels which broke their anchors in the North Sea in Scotland's severe gales.
The Petrojarl Banff, which has 4,400 tonnes of crude oil on board, lost tension in five of its 10 anchors and drifted up to 250m.
The Apollo Spirit, with 96,300 tonnes of oil, lost tension in one of its eight anchors but remained secure.
There has been no report of pollution at the site, 190km east of Aberdeen.
The Petrojarl Banff, a Floating Production Storage and Offloading vessel, is now stable about 70m from its original position.
An anchor handling vessel is on site and four others have been mobilised to assist.
All 67 crew on board the two vessels have been accounted for and the UK government classed the situation as "low risk".
The Scottish government said it was monitoring the situation and was being kept fully informed.
