Project 10510 Lider LK-110Ya

The Russian Navy is working on the creation of a force of military icebreakers and ice-class attack ships based on the newest nuclear icebreakers. Their task would be security of the Northern Sea Route and protecting Russias Arctic borders.

Russian President Vladimir Putin ordered a constant military presence in Arctic waters back in December 2013. This presence is necessary both for protecting the growing potential of the Europe-Asia transit gaining momentum on the Northern Sea Route and for maintaining Russias national security from the north. American expert at the Council on Foreign Relations Scott Borgerson: "If you take into account fees for the passage of the Suez canal, fuel costs and other factors that determine freight rates, the Northern sea route can reduce the cost of the flight of a large vessel carrying goods in containers by as much as 20 percent from approximately 17.5 to 14 million dollars, which will save billions of dollars a year."

The Leader-class icebreaker will ensure round-the-year navigation along the Northern Sea Route, both at its low-latitude and high-latitude lanes, breaking through ice of up to 4.3 meters thick. Ice of such thickness is quite rare. Icebreakers being built today (60MW icebreakers LK-60) are not able to break through four-meter thick ice, their icebreaking capacity is slightly over 3 meters. Leader-class icebreakers will be able to make a canal of up to 55 meters wide allowing for leading large convoys, hence the name.

The channel of LK-60 is 34-36 meters wide and the escorted transport vessels should have a high ice class. Besides, there is a task of ensuring a commercial speed for vessels in the ice convoy. It is about 10 knots. Leader-class icebreaker will be able to ensure such a speed in the ice of up to 2.5 meters thick. LK-60 icebreaker is not able to do that in the ice of such thickness.

Multi-hulled icebreaker would be more efficient for escorting convoys in the Arctic with the development of hydro-meteorological services, deployment of unmanned aircrafts, satellites, etc. This will allow for escaping ice ridges since such vessel cannot break through four-meter thick ice. However this icebreaker will ensure economically efficient speed of 10 knots in 2.5-meter thick ice. Such an icebreaker will cost RUB 50-55 bln (LK-60 costs about RUB 43 bln).

The Project 10510 Lider icebreaker is expected to have an engine of 110 megawatts and would be capable of cutting through ice up to 4.5 meters (14.8 feet) deep. The icebreaker is planned to have a displacement of 55,600 tonnes, a length of 200 meters (over 650 feet) and a width of 40 meters.

Atomic icebreaker leader of the project 10510 is designed for year-round escort of large-tonnage transport vessels deadweight more than 100 000 t and width more than 50 m all over the Northern Sea route, with cost-effective speed of approx. 15 knots in ice thickness approx. 2 meters.

JSC "OKBM OKBM" (Nizhny Novgorod) began the development of a technical project of nuclear power Plant (NPS) rhythm-400 for icebreakers of the new project "leader". The thermal capacity of the plant is 315 MW, which is 1.8 times more than the power of its predecessor-the rhythm-200 (175 MW). In 2016, the CCB began to develop a technical project.

The unique design of the newest Russian nuclear will provide transit on the Northern sea route even large-tonnage tankers and dry, which now can not use this route. The hull and power on screws of 120 MW worked in "Krylov State Center" Fsue will provide the icebreaker with unprecedented permeability in ice. According to calculations, the "leader" will be able to easily overcome the Arctic ice thickness of more than 4 m and lay a navigable channel for the wiring of vessels 50 m wide. "Leader" will be able to pass through the foot ice at a speed of 15 knots.

Afrikantov Experimental Design Bureau for Mechanical Engineering (Afrikantov OKBM, Nizhny Novgorod) has developed a conceptual design of RITM-400 reactor plant for Leader Icebreaker of 110-130 MW, IAA PortNews correspondent cites Aleksandr Pakhomov, head of the design bureaus department for development of marine nuclear reactor plants. It is planned that the ship will pass through two meters of ice at a speed of 14 knots (conventional icebreakers move no faster than two knots).
