Review of Vaygach icebreaker
NS Vaygach ("атомный ледокол Вайгач") is a Russian nuclear icebreaker. "NS" stands for "nuclear ship". The vessel is state-owned (by the Russian Federation) and operated by Atomflot. The Atomflot company provides all Russian nuclear icebreakers with maintenance and technological services. The company also serves the country's special vessels fleet.
One of Russia's icebreaker ships, Vaygach is a nuclear-powered, shallow-draft icebreaking vessel. It is the second of 2 similar-design ships - launched after the sister-ship Taymyr. Vaygach was built for the USSR (Soviet Union) according to an order by the Murmansk Shipping Company. Vaygach has an ice-breaker traditional hull. The design features sloping sides and highly raked stem to reduce ice loads and improve maneuverability.
The cold-resistant steel used for the vessel's hull was delivered by the Soviet Union. Initially designed for a crew of 100, the ship's large superstructure contains accommodation for 138 personnel. In addition to other social premises, there is an auditorium that doubles as recreational (lounge) room and winter garden used to provide fresh vegetables during the long polar night. Vaygach has a helideck and hangar for Kamov Ka-32 helicopter and is equipped with a stern notch and standard towing winch for close towing in hard conditions.
Vaygach is classified with the Russian ice-class LL2 by the Russian Maritime Register of Shipping. It means the vessel is intended for icebreaking operations on Arctic routes in packed ice conditions (up to 2 m / 7 ft thick ice during the months of winter and spring). The vessel's shallow draft additionally allows operations in rivers and other locations where the water is not deep enough for the big Arktika-class icebreakers and the ice conditions are severe, so refueling of diesel-powered icebreakers is close to impossible.
The Vaygach icebreaker's itinerary program offers North Pole expedition cruises and also longer itineraries on the Northern Sea Route along Russia's Arctic coastline.
Russia's nuclear fleet of ice-breaking vessels is used exclusively in the Arctic Ocean for escorting merchant ships and assisting research stations floating in the ice-covered waters north of Siberia. These ships are also used for scientific and Arctic cruise expeditions. The Russian nuclear ice-breakers must sail in ice-cold waters to effectively cool their reactors.
NS Vaygach icebreaker vessel details
The Taymyr-class vessels were designed with considerable effort put into improving their safety. These nuclear-powered ships were designed to operate in areas with only 80 cm / 2,6 ft of water beneath the keel. All critical systems are duplicated in order to improve reliability. This design also allows the icebreaker ship to maintain operational capability even after a collision with a 25000-ton freighter (SA-15 class) at speed of 7 knots (8 mph / 13 kph).
Vaygach and her sister ship Taymyr are among the last icebreakers with the WABS (Wartsila Air Bubbling System) marine technology implemented. The WABS releases pressurized air from nozzles (below the waterline) thus lubricating the hull and reducing friction between ice and steel.
Both nuclear ships were constructed at Wartsila Hietalahti shipyard (Helsinki, Finland) - hulls, superstructure, and propulsion. However, their nuclear reactors (power plants) were installed at Baltiysky Zavod (Baltic Shipyard) in St Petersburg, Russia).
Besides NS Vaygach, the list of other Russian nuclear icebreaker ships includes 50 Let Pobedy (2007), Arktika (2017), Rossiya (1982), Sibir (2019), Sovetskiy Soyuz (1990), Ural (2020), Taymyr (1989, sister-ship), Yamal, (1992), Sevmorput (1988, cargo ship).

Note: In the case of poor AIS coverage, tracking the vessel's current location will be impossible. You can see the CruiseMapper's list of all icebreakers and ice-breaking research ships in the "itinerary" section of our Icebreakers hub. All states and their fleets are listed there.

Vaygach icebreaker Wiki
- In 2017, Rosatomflot completed scheduled drydock works to extend the service life of the sister-ships Vaygach and Taymyr. The service life of the icebreakers' propulsion and nuclear reactors was extended to 200,000 hours, which enabled the vessels to serve for 5 more years (until 2022). Each of the ships operates with a single-reactor propulsion unit (rated power ~50,000 hp / 3,7 MW). The extended service life of the reactors allowed Atomflot to operate them without interruption, gradually introducing the "Project 22220" nuclear icebreakers (Arktika, Sibir, Ural) without breaking its contractual obligations.
