Taymyr (Russian: Таймыр; IPA: [tɐjˈmɨr]) is a shallow-draft nuclear-powered icebreaker, and the first of two similar vessels. She was built in 1989 for the Soviet Union in Finland, at the Helsinki Shipyard by Wärtsilä Marine, by order of the Murmansk Shipping Company. Her sister ship is Vaygach.
While Taymyr is slightly smaller than the Arktika-class nuclear icebreakers, with an overall length of nearly 150 metres (490 ft) and beam of 28 metres (92 ft) she is still among the largest polar icebreakers ever built. At the maximum draught of 9 metres (30 ft), Taymyr has a displacement of 21,100 tonnes. However, she can also operate at a reduced draught of only 7.5 metres (25 ft).
Taymyr has a traditional icebreaker hull with highly raked stem and sloping sides to reduce the ice loads in compressive ice fields and improve maneuverability. The special cold-resistant steel used in the hull was delivered by the Soviet Union. Although designed for a crew of slightly over 100, the large superstructure of Taymyr contains accommodation and facilities for 138 personnel. In addition to messes and other social premises, there is a large auditorium that doubles as a recreational room and a winter garden that can be used to provide fresh vegetables for the crew during the polar night. In the aft, there is a helideck and a hangar for single Kamov Ka-32 helicopter. Being an escort icebreaker, Taymyr is equipped with a standard towing winch and a stern notch for close towing in difficult conditions.
Taymyr is classified by the Russian Maritime Register of Shipping with the Russian ice class LL2, which means that she is intended for icebreaking operations on Arctic coastal routes in level ice up to 2 metres (6.6 ft) thick during winter and spring. The shallow draught of the icebreaker allows it to operate in rivers, estuaries and other locations where the water is not deep enough for bigger Arktika-class icebreakers and the ice conditions are so severe that refueling of diesel-powered icebreakers would be difficult, even impossible.
