The surrender of the icebreaker "Arktika" may be postponed due to late delivery of the turbine

The technical revision of the second main turbogenerator (GTG), created by the Kirovsky Plant (KZ) for the 22220 "Arktika" nuclear-powered icebreaker, may lead to another delay in the construction of the vessel, reports Kommersant.

The Baltiysky Zavod suspended the installation work in the engine room of the nuclear-powered vessel until the delivery of the unit, which is currently on the test bench of the short circuit. According to the schedule, the vessel must be fully prepared in the summer of next year. At the same time, newspaper sources claim that “it will take about one and a half years to unite the State Tretyakov Gallery with the supporting systems of an icebreaker.”

The supplier of both units with a total value of 2,7 billion rubles is Kirov-Energomash (KEM), which is part of the St. Petersburg Kirov Plant.

“During the tests of the low pressure cylinder (low pressure cylinder, one of the turbogenerator units) a number of technical deviations were revealed. At CEM, tests were suspended and representatives of a subcontractor were called in (the Ural Turbine Works, part of the Renova group) to eliminate deviations, ”said representatives of CEM.

It is reported that "Kirov-Energomash" plans to pass the TG to the beginning of March. However, the publication interlocutors at the Baltic Shipyard are skeptical about these terms.

Are they wizards there? It would be nice to get the unit by the end of March. It's not even the number of technical problems, but their "quality",

said one of the sources.

The Ministry of Industry and Trade asserts that the issue of manufacturing the State Tretyakov Gallery is under the constant control of the federal ministry and the State Corporation Rosatom. In the very "Rosatom" refused to comment on the difficulties in the construction of the icebreaker.

It’s not surprising, for some reason. The deadlines are shifted. But, it’s better to try and not to put raw. They will bring it. We will have new icebreakers. I have no doubt. Do not rush.

If Rosatom declined to comment, then it has nothing to say.

The main reactors are ready. The rest, I hope, will hold out. Although the cat scratches ...

Dimych Do not be sad. Correctly you say - let them bring to mind the brought aggregate. And the cat - the commander of the TFR, came to me. Cats are bored, they are waiting for March.

[HEATHER]

Svarog, he’s serious nowadays.

..will workflow ..

Is it really about the first product in the series to bring it up? This is a "series of technical deviations" of the serial unit. What test are you writing about? This is just a factory marriage.

Apparently, I think so, as someone thinks, he will not row weakly on the cap. Apparently this is not a constructive problem at the design level, but stupid factory negligence.

[Mountain shooter]

However, the working moment. It happens all the time. And not only with us. What is the sensation?
Americans won an aircraft carrier can’t surrender a year soon ...

Unfortunately, it has become a habit everywhere in our country. From the word "everywhere."

Unfortunately, nothing We would have managed to surrender Ivan Gren’s Syndrome before the deadlines for the operation of Soviet icebreaking projects (the Soviet Union was the first to be disposed of), otherwise we would have to remain indefinitely without large icebreakers.

[BVS]

What are they (Americans) behind schedule? Or on schedule?

Icebreakers of the LK-60YA type (project 22220) are equipped with a single main power plant (GEM), which provides electric power to both the propeller engines of the nuclear-powered ship and the entire ship's electric power network. The creation of a single power plant determined extremely stringent requirements for the regulation, control and protection system of the two main 36-megawatt turbogenerators that are part of the PTU-72.
So when an icebreaker moves in ice (and this is about 60 propeller reverses per hour), a steam turbine installation must maintain the speed of the turbogenerators with the accuracy required to maintain a frequency of 50 Hz in the ship network.
... There were no such requirements for the control systems of the main turbines on all previously built Soviet nuclear powered ships: autonomous turbogenerators were installed there, working only on the shipboard network.

The terms of reference adopted by ZAO PKB Avtomatika for execution required a radical change in approaches to ensuring the speed and reliability of the control system for PTU-72 turbogenerators. During its development, it was an order of magnitude, compared with the power plants of Soviet icebreakers, the working oil pressure in hydraulic equipment and hydraulic drives of steam valves was increased: 170 atmospheres instead of 15.

[BVS]

And what does this text have to do with the article? it talks about the factory marriage of the SECOND main turbogenerator, and not about the unique system of regulation, control and protection of a power plant consisting of TWO generators.

Where did you see the word "marriage"?

And what is this, because the product is not unique - serial (already the second for this vessel).
This is a factory marriage.

[HEATHER]

Nude Nude! Not serial. Problems are not in the engine, but in automation. For a couple of days they will do it if they have not already fixed it. The program has crashed. Here and cuckoo. We don’t know the reason.

We HERE communicate in Russian, in which there is a difference between “You” and You. But God bless them with languages. Each has its own approach.

[Svarog51]

Victor Technical problems and factory defects are two different things. Technical deviations can be adjusted during installation and commissioning. Marriage is also different, sometimes it is possible to fix it on the spot.
R.S. Well, because of the flag of belonging, English reminded you of English. If you came from a foreign server - just let the forum users know about this event.

In our country (the former socialist Soviet from the USSR) access to the VO site is blocked. I am a retired Soviet officer. The first military rank is lieutenant engineer.

Do you have the option to change the checkbox through the settings? In some cases this happens. Then the negative will not pour so much on you. Try changing.

[BVS]

We did not serve for the flag (and the flag is different), we served for the country (and the country is different). Therefore, it makes no sense to change attributes for the convenience of others. The main thing is thoughts, not a profile card.

[Svarog51]

We did not serve for the flag

Then tell me which flag you served? And if you have not forgotten the oath, then do not cheat on her.

Therefore, it makes no sense to change attributes for the convenience of others.

Not for the sake of others, but for yourself. A flag indicates your affiliation. I am not a political officer, but you yourself understand that your affiliation cannot be defined otherwise.

The main thing is thoughts, not a profile card.

Account card - a profile on the site, sometimes they talk a lot about a person. I rarely start a conversation with those who do not have a name in their profile. So a person is hiding something. In your case, the name is indicated, so I’m trying to help you adapt on the site. If someone offended you, so remember the army. There, too, authority had to be obtained with their own hands. Military personnel are mainly military personnel, and this is the same attitude as in the army. You convey your thoughts in your comments, it is through them that forum users build relationships with you. Nobody can read thoughts.

This of course is all well and good, but one of the main laws of the system approach should not be forgotten: "The more complex the system, the less reliable and easier to disable!"
Soviet engineers were far from fools!

[BVS]

Svarog51,
I served the Soviet Army (it is already gone), then in the army of the new state (one of the former Soviet socialist republics). In this army, we (former SA officers) were not forced to take a new oath to a new country (not like Ukraine). I so I had and have one oath, the truth is to the defunct state.
My affiliation is a pensioner of one of the CIS countries. I can’t understand what my citizenship gives you at the moment. People’s thoughts do not correlate with the color of the passport.
There is no need to help me adapt on the site. I am not young and stupid.
Thank you for trying to help.
My thoughts are now in my words.

[Svarog51]

There is no need to help me adapt on the site. I am not young and stupid.

As you say. I also gave the oath of the USSR and did not change it to another. I also did not swear allegiance to the Russian Federation, although I served until my retirement. I will not insist on help. I have the honor.

[BVS]

I have the honor.
