The laying ceremony of the first icebreaker type LC-16 completed at the Vyborg Shipyard

At the Vyborg Shipyard (part of United Shipbuilding Corporation), the solemn ceremony of laying the first hull of the linear diesel-electric icebreaker project 21900М (ЛК-16), developed by experts of the Krylov State Research Center for the FSUE "Rosmorport", came to an end.

Representatives of federal and regional authorities, in particular the Ministry of Transport of the Russian Federation, the Ministry of Industry and Trade, the Federal Agency for Maritime and River Transport, FSUE "Rosmorport", as well as representatives of the Government of the Leningrad Region and the Office of the Plenipotentiary Representative of the Russian Federation in the North-Western Federal District are invited to the icebreaker laying ceremony. Alexander Soloviev, General Director of Vyborg Shipyard, Victor Olersky, Deputy Transport Minister, Georgy Bogachev, Deputy Governor for Construction of the Government of the Leningrad Region, and Konstantin Stasyuk, Deputy Head of the Federal Agency for Maritime and River Transport, spoke at the rally opening the event.


The technical design of the icebreaker was developed by the Baltsudoproekt Central Design Bureau, which is a subdivision of the Krylov State Research Center Federal State Unitary Enterprise (until the autumn of 2012, the Central Research Institute named after academician A. Krylov). The vessel with the production number 230 was laid in the slipway of workshop No. 9 of the Vyborg Shipbuilding Plant.

The icebreaker being laid today is the modernization of the 21900 LD project, the technical and partly working projects of which were also carried out by the Baltsudoproekt Central Design Bureau. According to the 21900 project, two icebreakers were built at the Baltic Shipyard in St. Petersburg: Moscow and St. Petersburg.

The 21900М icebreaker has a number of design differences compared with the 21900 project, in particular:

- the helipad is transferred to the bow of the vessel, the tank deck under the helipad with anchor-mooring facilities is closed;
- the width of the superstructure is increased from side to side;
- increased crew size;
- rooms for special personnel are provided;
- a heavy-duty cargo crane is installed;
- increased capacity of the propulsion complex;
- strengthened the strength of hull structures to reduce vibration;
- reinforcements of the corps in the area of ​​the ice belt were strengthened; the category of propeller columns was increased to the level of Icebreaker7;
- Installed equipment and systems that meet international requirements for environmental emissions and ballast treatment;
- increased autonomy of swimming.

According to the modernized project it is planned to build three icebreakers. According to the architectural-constructive type LD, type LK-16 is double-deck vessels with an extended tank, with an average location of the engine room, with two full-turn steering wheels in the stern and thruster at the front of the residential superstructure, with a helicopter landing pad at the bow and open deck aft.

21900М icebreakers have an unlimited navigation area. The main purpose is self-pilotage of large-tonnage vessels, towing vessels and other floating structures in ice conditions and on clean water, extinguishing fires on floating objects and other structures, carrying out work to assist ships in distress. In addition, the transportation of containers on the open part of the upper deck, including refrigerated containers with the corresponding power supply and other deck cargoes, was added to the icebreaker functions.

Brief specifications of the 21900M icebreaker:

- displacement of about 14000 t;
- the greatest length - 119,8 m;
- maximum width - 27,5 m;
- calculated draft - 8,5 m;
- speed of running in clear water - about 17,0 nodes;
- ice passing - 1,5 m;
- power of the propulsion complex is about 17 MW.

The area of ​​operation is the Baltic Sea and the Arctic seas in the spring-summer period.

    Joyfully.
    But on the atomic, sad.
    By space, rescue, auxiliary-to-be.

    really good news! especially because earlier (in Soviet times) icebreaker hulls seemed to be built in Finland. finally work will be loaded already our shipyards !!!

    You know, icebreakers of large types look very much like UDC and aircraft carriers, you could use this to build the AV-UDC groups

    But are the propeller shafts, or as they say correctly, not hidden in the casing so that accidentally not to damage the ice?

      not in the casing

      Do you know why a battleship cannot work in ice conditions? Because he has turbines. They need clean water. When clogged with ice porridge, it creates a vacuum in front of the screw. The propeller simply pushes out the remaining water, and an air cushion is created between the deadwood and the propeller. separate "nozzle", but not closed. And, in theory, there should be a compressor, for washing ice with air, in difficult conditions

      No, they are not hidden in the casing. To put it simply, the screws of ordinary ships are made of non-ferrous metal (bronze, brass something in this regard), and as you know, it is very fragile to chip. And the screws for icebreakers are made of stainless alloys, and you’ll break them on ice.

    I watched one program so there they showed how an icebreaker approaching difficult areas turns around and breaks ice with screws. They are now made of some kind of super alloys.
