Baltiysky Zavod received a contract for the construction of the fifth and sixth serial universal nuclear icebreakers of project 22220
The series of Russian universal nuclear icebreakers of Project 22220 "Arktika" will be continued, the Baltic Shipyard has received a new contract for the construction of two more nuclear-powered icebreakers. This was reported by the press service of the United Shipbuilding Corporation.
Atomflot and Baltiysky Zavod signed a contract for the construction of the fifth and sixth serial icebreakers of project 22220. Metal cutting for the fifth nuclear-powered icebreaker is planned for the third quarter of this year, commissioning in December 2028. The sixth icebreaker will be handed over to the customer in December 2030. The names of the future icebreakers have not yet been received.
- said the general director of the Baltic Shipyard Alexei Kadilov.
To date, the Baltiysky Zavod has put into operation three universal icebreakers of project 22220: the head "Arktika", which gave the name to the entire series, as well as the first and second serial "Siberia" and "Ural". Two more nuclear-powered ships, Yakutia and Chukotka, are under construction, with delivery dates in 2024 and 2027. Project 22220 icebreakers are being built to provide year-round navigation along the Northern Sea Route.
The main power plant of the icebreakers includes two Ritm-200 reactors with a thermal capacity of 175 MW each. Its main advantage over other similar installations is its compactness and efficiency, as well as an energy-efficient integrated layout. The design of the reactors makes it possible to work reliably with the rolling of the nuclear-powered ship with an oscillation amplitude of 45 degrees and a pitching of 15 degrees. The service life of the reactors is 40 years. Performance characteristics of the icebreaker: Length - 174 m, width - 34 m, draft 10,5 m / 9,3 m, power - 60 MW (on shafts), displacement - 33,54 thousand tons, crew - 54 people.
A feature of the 22220 project icebreakers is the use of variable draft using ballast tanks. Double-draft ships can operate both in deep water and in shallow waters in river beds, overcoming ice up to 3 meters in thickness.
