Harbour Icebreaker IB Ahto

Arctia Karhu Ltd.  provides harbour icebreaking and towing services in the Bay of Bothnia and the whole Baltic Sea. Harbour icebreaker Ahto was delivered to Arctia Karhu by Uudenkaupungin Työvene in September 2014. It is a 1A SUPER ASD class tugboat that fulfills escort tug requirements. In addition, the vessel is equipped for oil spill response in icy conditions.

As a heavy Arctic harbour icebreaker and escort tug, the vessel has been dimensioned to cope with the difficult, icy conditions in the Bay of Bothnia, where it will function as a harbour icebreaker for the Ports of Kemi and Tornio in wintertime. It is equipped with two azimuth thrusters, a towing arch and a winch.
