Vessel Description

YMER is a Swedish state-owned icebreaker operated by the Swedish Maritime Administration. Built in 1976 at the Wärtsilä Helsinki Shipyard in Finland, she is one of Sweden's most capable conventional icebreakers. Her diesel-electric propulsion system powering four propellers — two at the bow and two at the stern — gives her exceptional maneuverability in heavy ice conditions and the ability to break ice in both directions. She is designed to operate in the severe ice conditions of the Gulf of Bothnia and the northern Baltic Sea, providing icebreaker escort services to merchant vessels during winter navigation seasons. YMER has been a significant asset in maintaining year-round navigability of Swedish ports and shipping lanes that would otherwise be inaccessible during harsh winter periods.
