Icebreaker "Ilya Muromets" showed part of its capabilities during trials in the Baltic

The newest Russian icebreaker Ilya Muromets has been successfully tested in the Gulf of Finland. We are talking about the first stage of factory testing of an icebreaker, which is being built under a contract with the Ministry of Defense of the Russian Federation. From the report of the representative of the press service of the main defense department of the country for the Navy, Captain First Rank Igor Dygalo:

The tests were carried out in the waters of the Gulf of Finland and the Baltic Sea by the crew of the icebreaker under the command of captain Gleb Rutkovsky and the transfer team of the Admiralty Shipyards company from August 29 to the present.




Icebreaker completed the program of speed and maneuverability tests. Also the transfer team carried out the work of all systems and equipment of the vessel.

Deck facilities were also tested, including boats and scooters. Validated crane equipment "Ilya Muromets."

В press-service The Ministry of Defense of the Russian Federation for the Navy reports that the second stage of testing will last until September September 10. It will be held on the grounds of the Baltic Fleet and in the waters of Baltiysk.

The crew of Ilya Muromets and the admission team of the Admiralty Shipyards enterprise also carried out the most difficult element of the program of the first stage - the pull test. The commissioning icebreaker’s task was to approach the test “glass”, move the towing end of the winch, catch the hook and, slowly moving away to remove 960 meters, give full speed ahead. At this moment, with the help of appropriate instruments, the amount of tractive effort that the icebreaker was developing was to be recorded.

This icebreaker was tested in two days allotted: one day was allotted for the crew’s training, the second - directly for the measurement procedure. "Ilya Muromets" showed an effort in 97 tons, on 4 tons exceeding the specified characteristics.

From the statement of the captain of the first rank Igor Dygalo:
The vessel will work the anchorage at a depth of 82,5 m with a wind of more than 17 meters per second. There will also be worked out various options for the approach and landing of the helicopter at the icebreaker site.

    "... slowly moving away to a distance of 960 meters ..." - the main thing is to take a run? Wow tip from almost a kilometer. Or stretched so? belay

      No. This is the length of the tow line. It is calculated by cunning formulas with many unknowns. In a nutshell - the longer the tugboat (meaning the rope) is larger, the more efficient it is to dampen jerks when rolling ships. An extremely dangerous situation may arise in the sea when the tugboat and the one it drags are at the bottom of the wave, only on the opposite side of the crest ... a jerk will be inevitable in this case, and if the towing line is not correctly calculated, the rope will burst . Turning it on again in the stormy sea is a very, very complicated and extremely dangerous business for the deck teams of both ships. Therefore, in some cases, an insert from the anchor chain is made into the tow line; There are also other ways to reduce the load on the rope, but the simplest and most effective is the long length + weighting insert as a damper. Within reasonable (calculated) limits, of course ...

    “The vessel will work at anchorage at a depth of 82,5 m with a wind of more than 17 meters per second.” - Obviously, the military has its own idea of ​​"good maritime practice." The captain of a civilian ship will never anchor at such a depth, and with a wind of 15 m / s it’s prudent to anchor and leave to storm the open sea so as not to “break firewood” ... Good news, I'm glad that the fleet is being built slowly , even if not commercial / commercial / scientific. Big begins with small ...

    Performance characteristics
    "Ilya Muromets" belongs to the class of ice ships. It is suitable for operations with ice thickness not exceeding one and a half meters.
    Country of origin - Russia.
    The manufacturer is the Admiralty Shipyards enterprise.
    Intends for the Russian Navy.
    The crew consists of 32 people.
    Displacement - 6 thousand tons.
    The length of the vessel is 84 m.
    Width - 20 m.
    Board height 10 m.
    The icebreaker is characterized by a draft of 6,8 m.
    Speed ​​- 11 knots (economical) and 15 knots (full).
    "Ilya Muromets" is capable of continuous movement with an ice thickness of not more than one meter.

    Using new flange screws
    The icebreaker is equipped with four diesel generators with a capacity of 2600 kW each. Thus, the total power is 10 600 kW. Separate screw-steering columns are equipped with two comb motors. Each of them has a capacity of 3500 kW. It is planned that they will be powered by four diesel generators. The uniqueness of this icebreaker lies in the presence of ridge motors taken out of the hull. The screws, thus, are able to carry out their rotation on the shafts 360 degrees. Due to this, the icebreaker will be able to carry out movement in any direction. This ability is especially important when the ship is in the ice. According to experts, icebreakers very often have to back up in the Arctic zone. For a new icebreaker equipped with flange propellers, sidetracking will not be problematic either.

    How are you going to use the ship?
    The icebreaker Ilya Muromets will be delivered to the Arctic zone for effective independent ice pilotage of warships and ships of the Russian Navy. The ship will perform the following tasks:

    Patrol the territory of the Arctic zone.
    Tow other ships.
    To transport goods. For this purpose, it is planned to use the cargo hold of the ship, as well as the decks on which special refrigerated containers will be installed. Loading and unloading operations will be possible thanks to a 21-meter crane with a lifting capacity of 26 tons installed on the ship. Additionally, a crane will be installed on the icebreaker. Its carrying capacity will be two tons. The bow of the ship is planned to be equipped with a helipad. On the deck of the icebreaker there is a place for a multifunctional working boat BL-820 using an inflatable board.
    The icebreaker will be used as a carrier of additional crews (in the amount of fifty people).
    Pave the way on the ice surface to non-ice class ships.
    Supply coastal, island bases and airfields located in the Arctic zone.
    The icebreaker will also be used by scientists in conducting hydrographic surveys.
    In case of emergencies at emergency facilities, the vessel is activated during fire fighting. Especially for this purpose, the icebreaker is equipped with two fire monitors and a fire pump. Also, using this pump and a multifunction boat, it will be possible to carry out localization and collection in the event of an oil leak. To collect oil products from the water surface, the icebreaker provides 400-meter boom barriers.
