The lead nuclear-powered icebreaker "Arktika" of project 22220 headed for the North
The lead universal nuclear icebreaker "Arktika" of project 22220, which underwent scheduled repairs, completed post-repair tests and headed for the North. This is stated in a press release from the USC, which was sent to the Military Review.
The icebreaker has completed testing in the Gulf of Finland, confirming compliance with the design specifications. After calling at the Baltic Shipyard, "Arktika" went to Murmansk, where in the near future it will begin work on escorting caravans along the Northern Sea Route.
Recall that the icebreaker has been under scheduled maintenance for the last five months, during which warranty repairs were carried out with the replacement of the starboard electric motor. To do this, the shipbuilders had to cut out part of the side skin. In addition, the icebreaker underwent an audit of the rudder complex, bottom-side fittings, and a new painting of the hull was carried out. The icebreaker with an already serviceable right propeller shaft electric motor went for testing in November.
The lead icebreaker "Arktika" of project 22220 was laid down in November 2013, launched on June 16, 2016 and put into operation on October 21, 2020. At the same time, the transfer of the ship took place with an emergency electric motor with power limitations "under certain guarantees and obligations." The icebreaker received damage to the right propeller motor as a result of mooring tests in December 2019.
A feature of the 22220 project icebreakers is the use of variable draft using ballast tanks. Double-deck ships can operate both in deep water and in shallow water in river beds, overcoming ice up to 3-meters thick without losing speed.
