The electric motor of the right propeller shaft was replaced on the atomic icebreaker "Arktika"

The planned replacement of the electric motor of the right propeller shaft was carried out on the lead universal nuclear icebreaker "Arktika" of project 22220. The icebreaker arrived at the Baltic Shipyard to complete the work. This was reported by the press service of the enterprise.

"Arktika" was in the dry dock of the "Kronstadt Marine Plant" for exactly one month, where the electric motor of the propeller shaft was replaced. To do this, the ship repairers had to cut out part of the outer skin. After completing all the necessary work, as well as servicing the icebreaker's hull, "Arktika" was taken out of the dock and, with the help of tugs, was transferred to St. Petersburg to the "Baltiyskiy Zavod".

At present, the vessel is at the berth of the Baltic Shipyard; the icebreaker will carry out a number of works on the final adjustment and adjustment of the systems. The icebreaker with an already serviceable right propeller shaft electric motor will be tested for testing in mid-October.

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.

But it is that Mikhalych ... it turns out that the electric motor burned out PLANOVO without having worked the required number of hours ...

Great! I was all worried when the planned replacement of the electric motor of the right propeller shaft will be carried out .... And I moved the tile in the toilet the other day - we are great! Go Russia!!!

The plan was drawn up after the electric motor was out of order. Why act like a fool?

There is a plan for an EXTRAORDINARY repair, and this repair is just that. And it turns out that many millions flew down the pipe according to the plan ... Who was responsible for this?

Are we already on you? It seems they didn’t pour it ...
I perfectly understand what I'm talking about, and the fact that this repair was EMERGENCY, that's what you need to understand, and they are trying to pass it off as CURRENT ...
Why was the malfunction of this electric motor revealed only after it was installed on the ship? As a result, the ship had to be cut to replace it.
There are a couple of billions in scrap metal, there are millions "down the drain," and most importantly, there are no guilty ones ...

Maybe not acting like a fool, but assessing the quality of work, for which they did not hesitate to take billions of rubles? As non-foolishness, would you share - who was punished for gigantic losses? Who responded to what for an extremely crappy, shameful job? Who, for example, bravely sewed an unstable engine into a case?

The HED under load is tested precisely during the MOORING tests. And here is the phrase that

Damage to the right propeller motor icebreaker received as a result of mooring tests in December 2019 year.

The author is inaccurate in his expressions:
1. Damage to the right HED occurred due to a malfunction of the power unit control system with HUGE currents on the windings.
2. And this damage to the HED happened DURING mooring tests, when all icebreaker mechanisms were tested under load.
Somehow, however.

[Mikhail3]

Mechanisms are tested under load on-site, that is, drives. Shafts, screws, bearings, etc. The snap-in that can only be launched by building. Sorry, but it is a crime to test engines and their control systems locally. GREAT currents? If this word was used by those who were OBLIGED to calculate the load, then they should be shot. Not less) If the loads, as they should, are calculated, then either the project is complete shit, or there is no execution. If off-design, then the execution has nothing to do with it, but the project ... In general, these are not the words of engineers. Most of all similar to the excuses of the GREAT thieves.

Michael, you don't need to get so excited! So far no one has told us WHO IS GUILTY, tk.

Representatives of the Central Research Institute of Marine Electrical Engineering and Technology (TSNII SET, part of the Krylov State Scientific Center), who were engaged in the development of electric propulsion systems, believe that the fault in the manufacture of the engine is to blame for the incident. However, the leadership of the Leningrad Electric Machine Building Plant (supplier of the GED) blames the power surge from frequency converter at the GED.

[Mikhail3]

Alexander, you started to get excited about the caps.) Apparently the cry about GREAT loads should have explained to me that thieves and co-cakers HAD THE RIGHT to hand over shit instead of the engine, moreover, they were embedded in the body deafly, so that the body had to be cut) I tried to explain how it looks with the engineer's point of view, in the language you used. Well, about the quote you quoted ...
I somehow thought (well, I'm stupid, yes) that modern LARGE machines are controlled by computers, especially during testing. And everyone who did important things must be present at the tests. So that no one has lost anything in particular. So this is all a fairy tale for the poor, as our American "friends" say. Everything is reflected in the history of operations. What currents were, what commands were given and passed, after which and how the system was covered ...
Who blames whom ... In general, it is known exactly who messed up) Judging by these children's squeaks, instead of a calm speech, neither those nor those coped.

.......... But no one in the world has performed such a control system for electric motion with frequency converters, electric motors for such capacities with such dynamics. According to the initial technical requirements, we have there 3 seconds load shedding of 20 MW and 15 seconds - a set. And this is not an ordinary power plant, but a transport one. The icebreaker needs to quickly stop, turn around, and so on. Here you can see that additional careful system tuning is needed.
It is explainable. If there were bench tests for reactors and turbines, Afrikantov OKBM had experience and the Kirov plant also managed to restore the lost competencies, then it was not invented for the stand electric propulsion. This is a completely new technology for such capacities. In this case, the electric propulsion is adjusted at sea in working sea trials. Such a supernova system will take time - months, God forbid, less. Hopefully by May we will sort it out ...............

How was it there? "Begin with yourself"?

You did not call my words nonsense, but the quote I quoted (see the link) from an interview with Ruksha Vyacheslav Vladimirovich, Deputy General Director of the State Atomic Energy Corporation "Rosatom"
His education
Graduated from the Leningrad Higher Marine Engineering School named after Admiral S.O. Makarov with a degree in Operation of Ship Electrical Equipment. Qualification - electrical engineer.

I repeat the question: who are you who called him a liar?

[Mikhail3]

This is the internet. noticed? There are all rukshas, ​​megarukshas and superrukshas. And only the CONCEPT ITSELF has value here, and not the one who expressed it. So that's it. If some ruksha really said this (which is absolutely not a fact, this is the Internet, I repeat), then he is not an engineer, not a specialist and in general no one, in the sense of a modern effective manager, a thief and a scoundrel, and this is not an insult, but a diagnosis )
The fact is that if the system is as directly innovative as he says, then he HAD NO RIGHT to install it on the ship, without a comprehensive set of tests on stands, simulators and directly assembled at extreme loads. This is an engineering alphabet - if the system is the latest, then it is NOT IMPOSSIBLE to install it on an object without a full set of tests.
It's so basic it's ridiculous. What kind of genius does it take to cram equipment into a huge object that you don't know about, will it work at all ?! An engineer cannot do that in principle, this is madness.
But this is exactly what thieves and scoundrels do, that is, effective managers who have power here. In their gigantic intellect, they, in principle, are not able to understand all the madness of such a decision, but to shove the object as soon as possible in order to get bonuses and better hide the stolen goods, this is just for them.
Well done, you guys. Thoughtful analysts))

[Dva parovoza]

And then act the fool, so that "measure seven times, cut once", or immediately cook the garage door (so that the body is no longer cut) - suddenly everything does not go according to plan ...

[Kushka]

He "planned" worked zero hours. It so happened - the problem
with one engine out of three, arose from scratch.
There was no reason to keep such a giant in the dock for an unknown amount.
There are also two installations with a head - the power is immeasurable.
And on the NSR, work is up to the throat, the dock is also scheduled every day.
Yes, and such engines "in the warehouse" are not lying around.
And how the "eggheads" found a solution to the problem, all the technology
the operation to replace the engine was thought out - I drove into a hole in my shura,
one or two and ready for the new winter on the NSR!
Do not forget - no one in the world has such a whopper, everything is there
unique.

There are 6 rowing electric motors on the icebreaker (2 for each shaft). The problem was with one.

[Kushka]

You are right, I made a reservation, lines three, engines 6, thank you.

[BABAY22]

The icebreaker went on sea trials in the Baltic Sea on June 23. During the tests, it was planned to check the operation of mechanisms and equipment, test the rowing electrical installation and maneuverability, rescue equipment, navigation systems. It was noted that the ship went to the test with a damaged right-hand propeller motor as a result of mooring tests in December 2019.

Earlier it was reported that after the completion of the stage of sea trials and return to the Baltic Shipyard, the icebreaker will be handed over to the customer with an emergency electric motor with power limitations "under certain guarantees and obligations." It is planned to replace the emergency electric motor at the icebreaker during the docking in Kronstadt in August 2021.

An icebreaker was repaired in the tsarist dry dock. When the battleships docked in it.

[UA3QHP]

This icebreaker will be slightly more displacement than the Tsar's battleships.

[75 Sergey]

I hope this is an accident.

[Brturin]

The head in the series ... everyone must work on it, so that the rest does not repeat itself ... they will work out the work with engines, converters, turbines, for which at one time ...
Turbines have become a key problem for Arktika. They were supposed to be tested by the Ukrainian Kharkov Turbine Plant, but after 2014 the stand had to be built at KEM. As a result, the delivery time for the equipment was disrupted https://www.kommersant.ru/doc/4180288

What kind of cross-handed testers are there? How could the main power plant be damaged

How could the main power plant be damaged

In a couple of days, the electric motor will turn not only into the "main" power plant, but also into the whole body of the icebreaker !!!

[Okolotochny]

With a nuclear reactor)))

[Serg65]

And with an atomic motor!

[zwlad]

Lehko and at ease if the protection in the converter is not tuned up according to normal

[Ros 56]

And striped and khokh ly on their icebreakers will be able to do so ?????

[zwlad]

Some crooked engineers have designed a converter. Other crooked production workers made a defective engine. The third crooked managers decided to install it all on the icebreaker. As a result, what was supposed to break - broke. Now, through heroic efforts, all this has been corrected. Someone else for all this disgrace will receive prizes and possibly orders.
That's how we live.
So what to do? Specialized design institutes were poured down the toilet. Qualified personnel were dispersed. And now all this technique is being designed by yesterday's students without experience. It's strange that only one engine was killed.

An interesting picture is observed: the authors of these messages were bombarded with quite logical and legitimate questions. Draw conclusions, what is more here - the notorious jingoistic patriotism or organized trolling ...
