The lead nuclear-powered icebreaker "Arktika" has completed tests and is ready to move to the North

The lead universal nuclear-powered icebreaker of project 22220 "Arktika" has completed the second stage of sea trials, the vessel is fully ready to sail to Murmansk. This was reported by the press service of the Baltic Shipyard.


The second stage of sea trials of the icebreaker took place from June 23 to September 16 in the Gulf of Finland and the Baltic Sea. During the tests, the operation of the mechanisms and equipment of the "Arctic" was checked, the electric power system was tested in sea conditions and the maneuvering characteristics of the vessel at various draft options.

The sea trials program has been completed in full. Shipbuilders, contractors and delivery crews have done a lot. We are satisfied with the results. Nuclear icebreaker "Arktika" is ready to sail to Murmansk

- said the general director of FSUE Atomflot Mustafa Kashka.

At present, the icebreaker is at the outfitting wall of the Baltic Shipyard shipyard, from where it will leave on September 22 and begin its transition to Murmansk. The transition is planned to take about 2 weeks. The delivery of the icebreaker to the customer is scheduled for November 8 this year.

The icebreaker will be delivered with an emergency electric motor with capacity limitations "under certain guarantees and obligations". The replacement of the emergency electric motor on the icebreaker is planned to be carried out during docking in Kronstadt in August 2021. The icebreaker received damage to the right propeller motor as a result of mooring tests in December 2019.

The Arctic nuclear icebreaker is the lead vessel of Project 22220 in a series of three vessels being built at the Baltic Shipyard in St. Petersburg under a contract with Rosatom.

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. According to project data, new icebreakers will become the largest and most powerful in the world.

    Good news. But why will the electric motor damaged in 19 be replaced only in the 21st? Or is it still more important to put the ship into operation by this winter, albeit in an incomplete version?

      The engine will only be ready at this time. We decided that it makes no sense to marinate the finished ship for a whole year at the wall.

        And this is definitely correct. Let him plow.
        It seems to me that all orders have already been ordered for his support.

      A more correct question is why they signed an acceptance on a ship that cannot be operated. For the year that the steamer will stand waiting for repairs, warranty periods will come out for almost all equipment. And all the failures that will come out during further operation will be eliminated not by the shipyard at the expense of the guarantee, but by the shipowner, at its own expense.

        Have you read the article?
        The icebreaker will be delivered with an emergency electric motor with power limitations "under certain guarantees and obligations"

        It will be operated with restrictions and the engine replacement warranty will not go anywhere. And the manufacturer will replace it. Everything else is your speculation.

              Here you express your theoretical fantasies, and I work with this in practice. With another shipyard only. The guarantee is one year from the date of signing the acceptance certificate, then - go fuck it.

                The new "tank" came from the factory for 5 years in service. A representative came and eliminated silently.
                And for this year, all that they can - they refuse guarantees under the pretext "you yourself broke".

                Broke it yourself - fix it yourself. Marriage - always eliminated by the manufacturer.

                  They also don't really want to go. Most of the work has to be organized independently, by third-party contractors. Well at least the shipyard pays the bills. To organize a warranty service somewhere abroad is generally an unthinkable business for them.

                  So it falls off by itself. And the shipyard refuses to eliminate. So much so that it is easier to eliminate at your own expense than bickering with them.

                  These are not teasers, although you might have a hard time making the difference.
                  You have to call this audience somehow, in order to distinguish it from normal, real patriots like me. Those who see and clearly understand that there is a problem, they have brains and knowledge, and they understand that it must be solved.
                  And the word at which you are offended - it refers to others to others. They have no brains at all, only the cerebellum, so that they don't lose balance when they wave the flag. If you consider yourself to be such - well, your business, in fact, I can not help here.

                  An analogy can be drawn with medicine. I am like a doctor who says "you are sick, it takes a long and painful treatment" or "there is only amputation", "there is no point in treating, send to euthanasia", "the patient has died a long time ago, bury it already."
                  The second is like a patient in a madhouse. The orderlies gave him a shot, he is happy, he jumps and waves his arms.

              So what's the point that it works now. The steamer will stay. When it is repaired, and it will be needed in real work at full capacity, it turns out that the warranty for all equipment is over, and even the most obvious defect will have to be eliminated at its own expense.
              Or do you naively think that a steamer can be built without marriage and jambs?

                      But seriously, to call any self-propelled ship a "steamer" is a tradition that the devil knows how many years. Regardless of the source of energy, and how it is converted. Even submariners sometimes call their boats "steamers".

                      Hmm. It is very sad that people like you operate nuclear "steamers" from "another" shipyard. However, I would not be surprised that they break constantly with you. Your competence is extremely low, apparently. I hope I'm wrong.
                      And yet, you also call the kettle a steamer? Does he boil water too?

                      But, at least, I already understood that you saw the steamers only in pictures. My whole life is connected with them, from different sides. I wanted to share some knowledge here, but they don't want to listen to something.

                      And I did not say that I operate nuclear steamers. No need to invent. Only TV presenters from federal channels behave this way.

    The power will be 40 megawatts instead of 60. (as far as I understood for symmetry, one electric motor will be turned off on the other side). Bad? Bad of course. But here you need to know - does the maximum thickness of breaking ice depend on the capabilities of the case or power? I'm not an expert, I won't answer. Well, he will break ice not under 3 meters thick, but 1.5-2 is it called "Without leaving the pier"? Well, they don't build ports where the ice is 2 meters thick at the quay wall ...

        Ugh. Soryan. I had a design size of 3 meters. In Dikson, of course, ice of 2 meters was the norm at one time (in winter).
        But in the first year of operation, the icebreaker would hardly have been raped with maximum loads. Although from the point of view of media, the trip to the North Pole is always good, and especially for new technology.

      I am also not an expert, but as a person who saw with my own eyes the work of "Taimyr" and "Vaygach" in the Yenisei Bay, I can say that the thickness of the ice being broken depends on the strength of the hull, since the icebreaker does not ram the ice, like the Greek trireme, but crawls over it with its hull and breaks it with a mass. But in order to crawl onto the ice, you need engine power. Although the ice is slippery, it is necessary to push such a carcass onto it.

      He will not break anything. Because they won't let him out of the port. An inoperative engine is a vessel with limited seaworthiness. Let's admit a separately agreed transition to the place of repair / sludge. But there can be no talk of any work. Any port control inspector will draw code 17/70, and that's it.

    Even with an emergency electric motor, the icebreaker is a powerful vessel. And it makes no sense to keep him at the outfitting pier for a year. It looks like it will work, it will run in. And, in the meantime, an electric motor will be made to replace the limitedly fit one. Seven feet under the keel, Arctic!

          This means that according to the "direct circuit", as before, the electric power is supplied to the propeller motor. Such a scheme on all icebreakers of Soviet and Russian construction, also on diesel electric ships of the Ob type, refrigerators of the Siberia type and the Dauria type (worked on the last two). VRK is a rudder propeller. Interesting schemes on the destroyers Zumwalt and the English 45 project. There are many new things at Arctic, but they will not tell us everything, but I realized that serious developments have been introduced.

      Out of six? There are only three on the propellers.
      Each kit includes the following components of a single electric propulsion system: three asynchronous electric motors for propeller drive, two main generators driven by a steam turbine, an excitation control system, and an electric drive for an anti-icing device.

          There are also plans for "triple" (30 MW) and "quad" (40 MW) asynchronous. It is a scalable line of motors. It is based on a 10 MW electric motor. By the way, "Stroyennye" are going to bet on "Leader". But these machines cannot be physically divided into 10-megawatt sections, because they are one. This can be clearly seen in the picture below. smile
          And yet, the motor now has to be somehow restored in place. It is unrecoverable.

    A breakdown of the stator winding has occurred. Lost not a third, but the sixth part of the power. The motor consists of two parts on one shaft. Writing that the engine failed as a result of mooring tests is not correct. The engine is out of order WHEN PERFORMING THE MOORING TEST.

    Representatives of the plant stated that due to a voltage surge during mooring tests, 4 phases out of 6 were damaged. And the Central Research Institute concluded that the GED
    out of order as a result of a marriage in its manufacture. It will take 12-18 months to replace the HED. Rosatom decided to take the icebreaker back, under the plant's guarantees that they would replace the engine when ready.

    I read that the nuclear-powered icebreaker Arktika needs docking. After a breakdown on February 4 at the atomic icebreaker "Arktika" undergoing testing, one of the propulsion electric motors was declared irreparable. In order to avoid long-term downtime of the vessel, Rosatom considered the option of accepting it with a faulty engine under the shipyard's obligations to carry out repairs. Then the capacity of "Arctic" will temporarily decrease by a third, to 40 MW. But this is just a net loss in icebreaker power. The problem arises from the fact that the unused propellers of the emergency electric motor significantly slow down the icebreaker "Arktika" and negatively affect the controllability of the icebreaker, which is unacceptable in the Arctic. As an option, it is considered placing the emergency icebreaker in dry dock in order to dismantle the propellers of the emergency electric motor.

        No, you don’t understand, they don’t want to cut the case anymore, you can still use it like that, at 2/3 power. Cutting the hull of a NEW icebreaker is already too much. They say that the icebreaker "Arktika" will dock in order to remove the propellers from idle engines. So that they do not interfere with the movement and do not interfere with the control of the vessel, in the form of passive resistance, like a protruding non-working part of the equipment. And to cut the body - this is when there will be a planned or major overhaul, in 10 years.

          Of course, I know that such a practice exists and was used ... in cases of curvature of propeller shafts, for example, to remove vibrations .. In our case, as I understand it, one of the electric motors burned out, but they are on the shafts in pairs in this project? Therefore, we are talking about not overloading the rest, but working at reduced power .. And in your opinion, it turns out that out of three propellers there will be only one? and if it is lateral, and not central, will they compensate for the U-turn with the steering wheel all the way? The discord turns out to be practically ...

            No, it's a little different there. Representatives of the Leningrad Electric Machine Building Plant said that due to a voltage surge during mooring tests, four phases out of six were damaged and it was impossible to restore the performance of the nose winding of the engine, due to a short circuit to the hull, the propeller motor on the right shaft failed.
            There are two generators and three propeller motors. Each of the power plants has a capacity of 20 MW and weighs about 300 tons.
            Here is the right one, just completely out of order. Left and center remained. Already in this configuration, it is required to compensate for deviations from the course due to rudders + still fixed propellers of the right HED - interfere with forward movement and maneuvering in ice. To reduce the negative impact, it is proposed to remove the screws from the right HED and provide for a fixed steering wheel compensating for the inoperative right HED.

                These are not questions for me. To be honest, I have the same many questions for such carelessness. But the guilty, as with the PD-50, will not be found and at the moment we have an icebreaker - a cripple. And it cost money as new and full.

              You express some unhealthy fantasies. A vessel with a faulty engine is prohibited from sailing. This is called a "ship not seaworthy".
              A one-time drive to the place of repair or sludge is allowed. In lightweight conditions, and with the adoption of special precautions. But which ice, which north? Are you out of your mind?

              Remind me of another steamer, with one faulty engine, which did not even go to sea, but simply to the Volga? Only 9 years have passed and have already been forgotten. There, too - the steamer was supposed to stand "at the fence", but there either a bribe was given, or an administrative resource was used (the owner of that pelvis was a State Duma deputy). The pelvis went on a flight, turned over, and drowned more than half of the people. They wrote an excuse that the pelvis was old, but this does not stand up to criticism, steamers are operating much older.
