FRANKFURT (Reuters) – Maritime rescue services and firefighters in Germany’s Baltic Sea have extinguished a fire on an oil tanker and brought the vessel safely into the port of Rostock, the city authorities said on Saturday.

“The ship is safely moored…there is no more fire. The tanker was dragged into Rostock overseas port early in the morning,” said a statement on the city’s town hall website, adding the cargo was not affected.

The fire broke out on Friday aboard the Germany-flagged, 73-metre-long tanker Annika, carrying around 640 tonnes of oil.

Divers were checking for possible deformations or cracks in the hull, the statement said. Police and marine investigators will inspect the ship to investigate the cause of the fire.
