Work has begun on the alignment and installation of the Russian M90FR gas turbine engine on the frigate "Admiral Golovko"

Shot from the video of the Severnaya Verf plant

The information about the completion of the loading process on the frigate "Admiral Golovko" of project 22350 of the domestic gas turbine power plant was confirmed. We are talking about work at the Severnaya Verf enterprise. The channel of the shipbuilding enterprise provided information that, in addition to the first gas turbine engines, gearboxes manufactured by the Russian Federation were loaded into the hold of the aft compartment of the frigate.

The main gas turbine power plant M90FR was created by the specialists of UEC-Saturn. Additional work had to be done to load it onto the ship. In particular, three decks were dismantled in the slipway shop. A special floating crane was used to load the gearboxes. The fact is that the gearboxes are much heavier than the turbines, so the lifting capacity of conventional cranes installed on the factory embankment is not enough for them.

Work has begun on the so-called alignment and installation of the gas turbine engine. This work, as noted, is designed for several months.

The installation of a Russian gas turbine power plant on the third frigate of Project 22350 is an important event. The fact is that the first frigates of this series (and these are "Admiral Gorshkov" and "Admiral Kasatonov") run on gas turbine engines of Ukrainian production. At one time, their deliveries to Russia were carried out by the Zorya-Mashproekt company. Now import substitution has been carried out.

M90FR engines from "Saturn" are afterburners. The cruise power plants are Kolomna 10D46 - diesel engines.

What does "so-called" mean ?! On tanks, this kind of work requires a certain amount of effort, but here they are much more powerful and heavy units!

[Victor_B]

The Ukrainian gas turbines replaced the import, otherwise after the Maidan it was completely sad ...

[Crowe]

Great news! We can whenever we want!

We can when we want!

But with gas turbine engines, the task turned out to be extremely difficult ...
It took seven years to replace the Ukrainian import systems!
But now - everything is different!
(Well, almost everything ...)

So after all, the film says that in addition to the turbines, the gearbox of domestic production was also loaded on the ship.

[Kazarinovsergen]

Lagged behind life, watch the film about marine engine building on U-Tube, there is just a part of the film about the gearbox

[Vadim Zhivov]

Well, there was a "loss". Good luck to the shipbuilders !!!

At the end of the note there is a mistake - for 22350 cruising diesel engines - 10D49, not 46.

[Mountain shooter]

A tremendous amount of work had to be done, both in the main production and in subcontractors, so that like this: "we install OUR gas turbines on our frigates ..." Everything that does not kill us makes us stronger!

[Elturisto]

Are yours Ukrainian?

[antivirus]

again, not 10 pieces of 100 VI have laid and center the wrong GEM.
when will it reach AB?
probably not according to Feng Shui toilets are located in the office and design bureaus ... yes, and in the General Staff

[voronin]

Additional work had to be done to load it onto the ship. In particular, three decks were dismantled in the slipway shop.

Just thinking out loud: since the loading of the units was expected, was it not logical to leave this place unassembled and covered? Or does the strength of the case drop dramatically?

[maksbazhin]

perhaps technological features, until you make the floor below you reach the ceiling :)

[Stepan S]

As a rule, schematic sheets are made in the decks for the installation (dismantling) of the main engine and the holes are not cut out, but several hundred nuts are unscrewed. We did this on the ship on our own, unscrewed and removed the sheets to replace the main engine, the work took a day, twisted everyone who got the key.

On this, and many more projects, it is precisely cut out, the rigidity of the hull is higher, on Kuza, in general, five decks were cut out in order to replace the boilers))

[Orkraider]

Greetings!

Just thinking out loud: since the loading of the units was expected, was it not logical to leave this place unassembled and covered? Or does the strength of the case drop dramatically?

It was impossible to leave it open, it was launched, so as not to waste time and continued work afloat on the installation of equipment (some of the work is done only after launching). This significantly accelerated the overall progress of the work.

Just good fellows that they dared to do so.

In general, according to the technology, it is impossible to mount a power plant afloat, since in addition to the main engines, it includes shaft lines and propellers, which are mounted after the DGTA. Let's go for tricks. When building the head. No. 923, a non-standard technological scheme was applied - propeller shafts were brought to it, propellers were installed and launched. DGTA will be mounted on order at the outfitting embankment and the shafting will be centered (the final alignment according to the rules should be done afloat).

I'm certainly not an expert in ship design ... but only this phrase jarred me? How can you make a ship, and then disassemble it to fit the engine? Is ... Is this okay?

[Flooding]

In a situation where the body is formed, but there is no engine, and there are no exact guarantees of delivery times?
It seems that in such a situation, there were no other options.

[dragon_13364]

those. Is it possible to freeze the construction of residential buildings, but the ship's hull is not in the dry dock?

[Flooding]

Of course. Because it takes up the dry dock space that is needed today.
In addition, shipbuilders fulfill their part of the contractual obligations in good faith.
Do you offer them to work at a loss, receiving fines and fines, and idle?
Heh. Can you imagine how much your apartment would cost if it was located on board a warship?

[dragon_13364]

Hmm, an argument .... although I would not buy an apartment on a ship, which at any moment is ready to go under water, and "floats" so-so, but on an island.

[dragon_13364]

Speaking on the merits, I have no complaints about the designers and workers at all.
Although I was wondering why we have so few docks, both dry and floating? These are the strategic resources (sorry for the terms of game mechanics) of the country ...
Well, and still interesting - why are we not building a cruiser? It seems that they have always been the main backbone of the fleet, and reading the articles, you simply lose faith in the country's ability to do something larger than destroyers and submarines. somehow sad.

[dragon_13364]

no, actually it's a shame. I understand that the coastal fleet is also needed, but ... This is the same, but it also arises when at the parades of the Russian Navy! there are Soviet cruisers, not Russian ones. This is sad.
Although, this is just my opinion.

Of course, strategic nuclear submarines are small things for the Caspian Sea.

why aren't we building cruisers?

The day before yesterday, only a detailed analysis was here.
Check out, read.
Even the construction of corvettes and frigates was called by many as irrepressible fantasies. Are you talking about a cruiser ...

[maratkoRuEkb]

cruisers are not built because it is inefficient. If we compare a destroyer and a cruiser, then the cruiser is 1) large - you can shove a lot of missiles. 2) expensive in construction; 3) expensive to maintain. 4) build for a long time.
a destroyer, or better a frigate 1) less - we'll shove fewer missiles 2) cheaper to build 3) cheaper to maintain 4) build quickly.
Well, it turns out that in modern missile combat, while one cruiser is firing off its missiles, 3-4 frigates of commensurate cost will have time to send a missile salvo of higher density. When 1-2 missiles hit the cruiser, it will be incapacitated / combatted with a high chance. A missile hit on a frigate will also put it out of action, but the rest of the frigates continue to fight.
Plus, in peacetime, when you send a cruiser for repair, your fleet's combat readiness significantly sags. When the frigate is sent for repair, the potential does not sink so much. Likewise, the loss of a cruiser is very significant, in contrast to the loss of a frigate.

[donavi49]

Well, there are no engines. Can the electrical assembly shop walk? You don't need to saturate the compartments and combat posts?

This is a normal practice, when some key and voluminous components fly away into the unknown, and the task is to work on the order and minimize the completion time after receiving the necessary components.

Usually, either temporary structures or capital structures are initially installed, but not along the full profile or with a basic calculation for removal. Also, if for installation it will be necessary to open something (which is not provided for by the project), then this can be entered through the KB into the CD / RD. For example, a number of switch boxes or valves, so that during installation and dismantling, only the interfering section of communications and systems can be removed.

I am a "specialist" in this area, just like you. I have never even been on a warship - a "television expert". However, I think that those who design the ships have come up with something so that when replacing the engine, the entire upper deck does not have to be cut off. Luke, something, something or something ...

[alexmach]

Is it okay?

No, it's not okay. And there everything is noticeably more fun. From the very beginning, the messages about the propulsion system for him were very contradictory and confusing, and now the theories have been fully confirmed by this message - he was launched without an installed power plant, and now they will install and center it afloat, this is not usual. there were still speculations that apparently they had already ditched something trying to set afloat. (otherwise, according to reports, it turns out that the units for installation have already been delivered to him 2 times)

[Elturisto]

There are no problems with the gearbox - there is no experience of installation and alignment, before everything was done by Zori. GTE is also made in Nikolaev. The whole topic is muddy like from VK-2500, which is why MS supplies to Taiwan. :)

See the pipe?

No?)
Here, in its place, there is a technological cutout of the deck flooring for loading the power plant.

Smoking is harmful. And to provide for standard technological cutouts for loading and unloading (which is a normal procedure during repairs) of engines and other elements of the power plant is healthy and generally accepted.

[dragon_13364]

yeah, but we cut three decks on the finished hull.
You know, a material science teacher always told me that a cast case is always stronger than one welded from different sheets or with cut out technological holes, which were then riveted with caps ...
Hopefully on this frigate, such cuts of decks, bulkheads and other things have been foreseen, otherwise it will be inconvenient. Imagine: a wave hits the side and the whole ship creaks ...

[bukhach]

The cart creaks, and it is not oiled, an unsuccessful statement. The hum, the trembling of the hull, the vibration of the deck, and only the furniture creak from the rolling. Although the military, perhaps, creaks.

[Strannik96]

"I'm certainly not an expert in ship design."
Write about where you are a specialist, or ask the experts to avoid nonsense writing

[dragon_13364]

Well, if the "experts" start a dialogue like that, then I should probably leave this site.
after all, dialogue involves the exchange of ideas, and not the ridicule of the seeker of knowledge and answers by learned sages.

[lucul]

You yourself answered))))
These three carved decks provided the hull with the necessary torsional and shear stiffness.
If you leave the "holes" for mounting for a long time, then the ship's hull can "lead" and it will lose the required rigidity.
True, all this can be calculated even at the design stage, but it will be more expensive.

[dragon_13364]

thanks for the answer.
I hope that the designers were still able to foresee this and we should soon wait for the ship.

Cast hull of the frigate? Creatively! A new word in shipbuilding.

[Elturisto]

Apparently the teacher told you this to you in a kindergarten. Why is there a cast body in general?

[ZEMCH]

Quote: dragon_13364

You know, a material science teacher always told me that a cast case is always stronger than one welded from different sheets or with cut out technological holes, which were then riveted with caps ...

The entire hull is assembled from sheets and welded, they used to be riveted, the icebreaker Krasin is in St. Petersburg, so its hull is riveted, and the ship is more than 100 years old)))
When designing, places are always meant for technological cutouts for replacing the power plant, either in the board, decks, or pipes of the water intake (exhaust), the cables are taken to the side, some of the systems are removed and have quick-disconnect connections in this place)))

Imagine that before issuing comments that do not carry a semantic load, it is worth at least a little to understand the topic being commented on.

[iouris]

Nothing more significant happened. Well, okay.

[Jacket in stock]

Well this is how much the total price of these unfortunate ships soared?
Even if the money for the development of the production of the gearboxes themselves is not counted, but only the ship itself is stupid?

[Strannik96]

This is how much the price flew down from those who used to do for Russia.
The mastery of such a technique is the development of many areas of industry in Russia and is calculated for many years ahead and for many different installations, which in the end leads to significant economic profit and technical literacy of all participants, and also not unimportant - the system of technical education is being restored, starting as before with GPTU

Yes, do not care about them.
Moreover, they still have to do and send Chinese orders. They will not become much poorer.

[Ruslan Sledkov]

And no one will say at what speed the main engine allows this frigate to walk?

[Veteran]

The frigate is equipped with two 10D49 cruising diesel engines, which allow the ship to travel at an economic speed of 14 knots, while the frigate's maximum cruising range will be approx. 4500 miles.

[garik77]

Well, what can I say ..
Good luck!
