Review of Taymyr icebreaker
NS Taymyr ("атомный ледокол Таймыр”) 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, Taymyr is a nuclear-powered, shallow-draft icebreaking vessel. It is the first in a series of 2 similar-design ships, the second being the sister ship Vaygach. The Taymyr ship has a traditional hull for an icebreaker - sloping sides, highly raked stem, cold-resistant steel. Initially designed for 100 crew, Taymyr's superstructure contains accommodations for 138 service personnel.
This nuclear ship has an auditorium (doubling as a recreational room) and even winter garden for fresh vegetables during the polar night. Taymyr has a helipad and hangar for Kamov Ka-32 helicopter. The ship is equipped with a stern notch and standard towing winch for close towing in extreme weather conditions. Taymyr is an ice class LL2 vessel, which means it is intended for icebreaking operations on Arctic Ocean routes in level ice up to 2 m / 7 ft thick ice during winter and spring. The ship's shallow draft allows it to operate also in rivers and other low-water level locations.
The Taymyr icebreaker's itinerary program offers North Pole expedition cruises and also longer itineraries on the Northern Sea Route along the 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 Taymyr icebreaker vessel details
Both Taymyr and Vaygach ships were specifically designed to improve safety. They both operate in areas with only 80 cm / 2,6 ft of water beneath the keel. Their critical systems are duplicated to improve reliability. The design allows the icebreaker to maintain operational capability even after a collision with a 25000-ton cargo ship (SA-15 class) at max speed of 7 kn (8 mph / 13 kph).
Taymyr and her sister Vaygach are among the last icebreaker ships with the Wartsila Air Bubbling System (abbrev WABS) marine technology implemented. The system releases pressurized air from nozzles (located below waterline) thus lubricating the hull and reducing the friction with the ice.
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 Taymyr, the list of other Russian nuclear icebreaker ships includes 50 Let Pobedy (2007), Arktika (2017), Rossiya (1982), Sibir (2019), Sovetskiy Soyuz (1990), Ural (2020), Vaygach (1990, sister-ship), Yamal, (1992), Sevmorput (1988, cargo ship).

Note: In 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.
Taymyr icebreaker wiki
- In 2017, Rosatomflot completed scheduled drydock works to extend the service life of the sister-ships Taymyr and Vaygach. 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 operate 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.
