Watch a video by the Norwegian Society for Sea Rescue of the evacuation below.

Risk of Sinking

The ship is partially grounded but may still sink. Eirik Walle, of Norway's rescue centre, told the media the ship is taking on more water than they can pump out of it. So there is no control of the leak and the stern is already in the water.'

No Injuries Aboard Tanker

There were no injuries aboard the tanker. Norwegian authorities have stated tug boat Tenax has also been involved in the collision, but its role in the incident is not yet clear.

Sture Terminal Closed

In connection with the collision, the Sture terminal in Øygarden Equinor will gradually shut down operations at Sture. Personnel at Sture without emergency tasks will also be evacuated. The shutdown and evacuation are said to be performed as a precautionary measure.
