A Stena Line ferry collided with a tanker carrying 12,000 tons of fuel near Gothenburg, Sweden, on Sunday morning.
There have been no injuries reported and no fuel spilt into the sea.
The accident happened near the island of Vinga in the waterway leading toward Gothenburg’s harbor.
The ferry, Stena Jutlandica, was carrying around 600 passengers at the time of the accident.
The ferry’s hull was punctured on the port side, but the vessel was able to enter port under its own power.
The Swedish Coast Guard has divers in the water checking the tanker’s damage and potential for an oil spill. The tanker is operated by Terntank.
Local media reports quote Niclas Mårtensson, deputy CEO of Stena Line, saying: “It was the tanker that hit us, not the other way around.”
An investigation is now underway.
