Vaygach (Russian: Вайгач; IPA: [vɐjˈɡatɕ]) is a shallow-draught nuclear-powered icebreaker. She was built in 1989 for the Soviet Union by Wärtsilä Marine Helsinki Shipyard in Finland by order of the Murmansk Shipping Company. Her sister ship is Taymyr.
On 15 December 2011, two crew members died and a third one was seriously injured in a fire on board Vaygach while the icebreaker was escorting merchant ships from Dudinka to Murmansk. The fire, which started in one of the crew cabins presumably due to negligence and was extinguished by the crew by 04:00 Moscow time, did not cause any damage to the ship's nuclear reactor.
While Vaygach 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), Vaygach has a displacement of 21,100 tonnes. However, she can also operate at a reduced draught of only 7.5 metres (25 ft).
Vaygach 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 Vaygach 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, Vaygach is equipped with a standard towing winch and a stern notch for close towing in difficult conditions.
