NS Sibir icebreaker Review

Review of NS Sibir icebreaker

NS Sibir ("атомный ледокол Сибирь") is a new design (and the world's largest) Russian nuclear icebreaker. "NS" stands for "nuclear ship". The vessel is state-owned (by the Russian Federation via FSUE Atomflot) and operated by Rosatom. The Atomflot company provides all Russian nuclear icebreakers with maintenance and technological services. The company also serves the country's special vessels fleet.

The vessel (IMO number 9774422) is Russia-flagged (MMSI 273123123) and registered in Murmansk.

Besides NS Sibir, the list of other active Russian nuclear icebreaker ships includes Rossiya (2027/Project Leader), Ural (2022/sistership), Arktika (2020/sistership), Yakutia (2024/sistership), Chukotka (2026/sistership), Stalingrad ((2028/sistership), Leningrad (2030/sistership), Taymyr (1989), Vaygach (1990), Yamal (1992), 50 Let Pobedy (2007).

NS Sibir icebreaker (nuclear ship)

Among the newest and largest Russian icebreakers, Sibir is the 2nd of the "Project 22220" ships (often called LK-60Ya). This is a special class of 7x nuclear-powered icebreakers designed and constructed in Russia.

Being the second in the series, NS Sibir's construction/assembly started with the keel-laying ceremony on May 26, 2015. The vessel (hull/yard number 05707) was launched/floated out from drydock on September 22, 2017, and was officially delivered/commissioned on December 24, 2021. NS Sibir is in service since January 2022.

These ships are currently the world's ever-biggest and most powerful icebreakers, surpassing the "nuclear cruise ship" 50 Let Pobedy (50 Years of Victory) by length (14 m longer) and width (4 m wider).

Negotiations between the Russian companies Atomflot and USC (United Shipbuilding Corporation) have been lengthy. In early 2013, the federal government allocated RUB (rubles) 86,1 billion (or ~USD 1,3 billion) for the project. Rosatom (also state-owned corporation) insisted that the two ice-breaking ships should have a total building cost of RUB 77,5 billion (~USD 1,2 billion). However, the offer was declined by the shipbuilder Baltic Shipyard (aka Baltiisky Yard). A second tender with the adjusted shipbuilding price of RUB 84,4 billion was announced in Dec 2013.

Due to the vessel's dual-draft (8,7 m / 10,5 m), Sibir icebreaker's itinerary program is based on Northern Sea Route shipping assistance and includes Arctic Russia sea navigation as well as polar river services. The ship's operational regions in the Arctic Ocean include Barents Sea, Kara Seas, Pechora River, Yenisei River estuary, Ob River (Gulf of Ob).

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 Sibir vessel details

Project 22220 class Russian nuclear ships have minimal draught 8,6 m (28 ft) and max draught 10,5 m (34 ft). The dual-draft design makes these vessels capable of operating in both the Arctic Ocean and in ice-covered rivers.

Project 22220 icebreakers are equipped with two RITM-200 nuclear reactors with a total of 350 MW thermal capacity. The propulsion power output is 1100 MW. The previous design was for 60 MW output (the reason why this class is alternatively known as "LK-60"). RITM-200 model is a pressurized water reactor developed by OKBM Afrikantov (Russian mechanical engineering company) and designed to produce power output 55 MWe (megawatt electrical). RITM-200 uses up to 20% enriched uranium-235. The reactor is refueled every 7 years and has planned lifespan 40 years. RITM-200 is also used to power Russia's newest and most powerful aircraft carriers (Project 23000E).

Sibir ship's maximum ice-breaking capability is 2,8 m (9 ft) at cruising speed between 1,5-2 knots (2,8 kph / 1,7 mph).

In May 2015 was reported that Russia made a decision on the development of the design for its newest nuclear-powered icebreakers to be able to move across Arctic ice of thickness up to 4.5 m / 15 ft. The icebreaker features propulsion power of 110 MW. Russia's new icebreakers are nearly twice as powerful as Project 22220 nuclear ships.

The steel for the Sibir ship (thick plate "Mill 5000") was supplied by the MMK company (Magnitogorsk Iron and Steel Works). The company is one of the world's largest producers and supplies with steel over 50% of Russia's shipbuilding. Steel plate "Mill 5000" is used for manufacturing Russia's naval fleet, as well as for building tankers and ice-class vessels. The steel is certified internationally, including by Lloyd's Register and Bureau Veritas.

The old Sibir (1977-built) was decommissioned in 1992. NS Sibir (IMO 7604491) belonged to the Arktika-class nuclear ships - the world's largest and most powerful ever built. The ship was also state-owned but operated by MSCO (Murmansk Shipping Company, later transferred to Atomflot).

The old icebreaker was one of all 10 Russian nuclear ships. It was also among the 6 vessels of this class - together with the old Arktika (1975-2008), Rossiya (1982), Sovetskiy Soyuz (1990), Yamal (1992) and 50 Let Pobedy (2007).

A curious fact is, that the old NS Sibir was Russia's only nuclear icebreaker with a superstructure not painted in red. Being retired in 1992, the ship was last seen in 2012 moored in Murmansk (northwest Russia) and awaiting its planned scrapping.

NS Sibir vessel has 1 dining room, Sauna, Library, Auditorium, Passenger Lounge, Volleyball Court, Gymnasium, 1 swimming pool (indoor, heated), Infirmary, 1 elevator, 1 helipad (helicopter deck) with a Mi-2 transport helicopter.

NS Sibir icebreaker Wiki

The vessel's construction officially started with the keel-laying ceremony held on May 26, 2015, at Baltic Shipyard in Sankt-Petersburg Russia. The nuclear ship (IMO number 9774422) is Russia-flagged (MMSI 273123123).

On September 22, 2017, the world's largest icebreaking vessel was launched (floated out from drydock) at the Baltic Shipyard. The ship's first nuclear reactor (RITM-200 steam generator/power plant) was delivered and installed in November 2017 and in December was installed the second nuclear reactor. Each RITM-200 reactor has thermal capacity of 175 MW (350 MV combined power output).

NS Sibir was delivered to FSUE Atomflot and commissioned on December 24, 2021.

In August 2019 was signed the shipbuilding contract for two more "Project 22220" units (Yakutia and Chukotka/ to 5x icebreakers total). Based on the contract, the shipbuilding cost per unit is RUB 50 billion (~USD 720 million / ~EUR 640 million).

The icebreaker is named after Siberia (originally Sibir) - one of the world's largest geographical regions spanning eastwards from Ural Mountains to the Pacific Ocean (west), the Arctic Ocean (north) and Kazakhstan-Mongolia-China (south). Yenisei River symbolically divides Siberia into Western and Eastern.

On September 5, 2021, Rosatom's Deputy Director (Maxim Kulinko) stated that the Northern Sea Route's year-round service requires two additional Project 22220 ships (6th and 7th). In April 2022 was announced that the Russian Federation plans to allocate from the federal budget RUB 118 billion (~USD 1,7B / EUR 1,6B) for the two icebreakers (cost per unit RUB 59B / USD 851M / EUR 807M), with scheduled deliveries in 2028 (Stalingrad) and 2030 (Leningrad).

As Project 22220 vessels are able to navigate both deep (sea) and shallow waters (river estuaries), ROSATOM received two types of ice-breaking ships for the price of one, which means saving hundreds of millions of USD.

NS Sibir and its sisterships are of utmost importance for Russia's strategy to open the Northern Sea Route (NSR) for commercial and military operations the whole year round. By 2030, the NSR is planned to serve vessels carrying 150+ million tonnes of shipments. The Russian Government gave ROSATOM the lead in the route's 6-year infrastructure development project, the total funding for which is RUB 734,9 billion (USD 11,37 B / EUR 10,17 B). Of those, RUB 274 billion were provided by the Government, while the remaining RUB 460+ billion were provided by investors, the largest among which are ROSATOM, ROSNEFT and NOVATEK.
