BDK "Ivan Gren" problems with reversing

The large landing ship of project 11711 Ivan Gren, being built at the Baltic shipyard Yantar, cannot be transferred the fleet due to problems with reversing. Tests are suspended until the end of January, reports VPK-News.

According to a source familiar with the situation, problems with reverse remain the only serious obstacle before the delivery of the Russian Navy ship, which was planned to be held in December of 2017.

The ship could be signed in December, but the fleet covers itself from possible problems in the future. The "Gren" previously had certain problems with seaworthiness and stability, but they were solved. There is a problem with handling when reversing

- he said

However, at one of the domestic design enterprises they harshly criticized the navigable qualities of the Ivan Gren BDK and questioned the need for serial construction of ships of this project. They stressed that the ship was created to operate in the river-sea zones for the transfer of troops from different theaters of military operations, and its dimensions were initially tied to the parameters of Volgodon locks and the height of bridges.

The 11711 project was conceived as a replacement for the small, outdated 775 BDK, it was literally “blind”. When the restriction for the class "river-sea" has disappeared, the BDK superstructure was increased. As a result of this and other design changes, ship stability has deteriorated significantly.

- said the shipbuilder

"Ivan Gren" - the lead ship of the project 11711, developed by Nevsky PKB. Laid at the Yantar Baltic Shipyard in December 2004 of the year, and launched only in May 2012 of the year.

The ship went to sea in the summer of 2016, then went to the factory to eliminate the identified deficiencies. The sea trials in the Baltic Ivan Gren returned in June 2017. November 30 began the cycle of state tests of the ship. 25 December last year, the press service of USC reported that "Ivan Gren" will give the Russian Navy until the end of 2017 year. 11 in January, the press service of the United Shipbuilding Corporation said that the tests of "Ivan Gren" will continue in 2018 year.

reverse problems remain the only major obstacle

this is not an obstacle, because the Russians do not cut the back)) a joke, otherwise the teachings will begin now))

[bouncyhunter]

Humor is a sign of intelligence. The news is not happy, of course, but to run with screams "Chef, u have gone!" we will not .

[marlin1203]

Why run after so many years of torment ...

[KVU-NSVD]

The large landing ship of project 11711 Ivan Gren, being built at the Yantar Baltic Shipbuilding Plant, cannot be handed over to the fleet due to problems with reversing

All guilty to create problems with the anus and all problems will be resolved as soon as possible B ... Yo ... PI ... No words, just confused thoughts !!!!

[PN]

If there are no words, then re-read the article.

[gerkost2012]

Poor "Vanya", it’s not even unfinished, it sucks! Almost fourteen years have passed since its foundation at the Kaliningrad Shipyard in 2004, a lot of alterations, etc. During this time, China built a large Navy. So maybe not spend money and effort on the BDK, but order them in the same China? Or in Japan? They are riveted there for a couple of years, as needed. It’s even easier to hire shipbuilders from other countries, maybe this will help to hand over the long-suffering BDK fleet.

[dik-nsk]

and kickbacks? are you trying on the holy?))

[PN]

Better in South Korea, they kind of like world record holders in shipbuilding.

[donavi49]

Not. China squeezed them by tonnage. Plus they have pretty weak landing forces. Totko is still disabled in practice.

In the Gren dimension, they have a mediocre Cheon Wang Bong - but it's controversial. There are no hangars - there is 2 aft platform and small fuel reserves. The docking chamber is small and, by default, is clogged with amphibious equipment. They came up with a crutch - putting the TDK on the upper deck. But they pressed everything in less than 5000 tons.


It is better then from the Indonesians to buy a successful Makassar (which the Koreans did by the way). 50 million dollars and normal DKDV. With a camera dock. 10k tons. Double or triple helipad with a wide hangar.

[_Jack_]

And what about our shipyards? Or fire everyone?

[PROXOR]

Well, either nationalize or let them go through the forest. Well, how much can you take this BDK?

[_Jack_]

Here, on the one hand, ships are needed, on the other hand, nobody wants to turn the country into a gas station in the world, their production also needs to be developed. But this is done, as always, through the back seat, and this is the result.

[PROXOR]

Exactly.
Let's face it. Russian people are like a rooster. The bird is proud until you kick it.
And proceeding from Stalin’s rule for athletes: I couldn’t get gold in competitions - you’ll go to mine in Magadan.

[Grits]

Well, how much can you take this BDK?
there is still the same Morgunov on the way

[Grits]

And what about our shipyards? Or fire everyone?
Our any factory can be loaded with the same ship type Grena. And they just have enough work for 25 years

[x.andvlad]

Apparently, we don’t have competent shipbuilding engineers in this area, since for 14 years they don’t know what to remake or fix in this ship so that it can serve in the Navy without any problems.
Maybe the Chinese or Koreans really have a “practice” to go through?
Judging by the torment with its construction, his fate will not be enviable. Sailors are superstitious people.

[x.andvlad]

Or maybe shipbuilding engineers have a problem?
The terms of reference for the design changed three times, the design took 6 years.https://ru.wikipedia.org/wiki/Иван_Грен_(большой_
landing ship)
It seems that the customer himself for a long time could not decide what he wants.
In any case, this is not the case.

[lazy]

in Indonesia instead of the su-35

[prior]

BDK Ivan Gren has problems with the anus.
Jo ... but, however, which for some reason was not noticed during sea trials in 2016.

[Azazelo]

And the captain was broken by flatulence. Here is the important news.

[marlin1203]

What kind of captain on a warship?

[lukewarm]

for the transfer of troops from various theaters of operations, and its dimensions were initially tied to the parameters of the Volgodon locks and the height of the bridges.

What are such different theater of operations inside the Russian Federation? What nafig amphibious assault on Volgodon? Explain to me someone!

[Evil 55]

problems with "reverse" is a tin for the BDK .. Only for the name of the author of the article, it’s time to give the Darwin Prize ..

[rumpeljschtizhen]

but the fleet is covering itself from possible problems in the future.

strange sounds ... they say the ship is good only the fleet they say kumazhirivaetsya :-)))) I think it will rot on testing and fine-tuning

[Nemesis]

Russia has big problems with those whose desire to control the Russian Federation is seriously ahead of their abilities, from here all the problems ...

[voyaka uh]

"that the ship was created for action in the zones" river-sea "" ////

Wow! So huge, but can’t walk on the oceans ...
What were the designers thinking?

[donavi49]

He can. Everything is simple there. If you make DKVD - then you can take a normal body to blow it on seaworthiness, efficiency.

But if you take the BDK - where does the main view of the landing in the shallow water / shore over the ramp / bridge come from, then you immediately have to dance from the PLATFORM form. Nothing else will come. Because of the bridge (which was supposedly recognized as erroneous and already dismantled) - Gren has slightly larger tolerances, so there is even a small bullet there (the 775 microbull is completely micro, and Gren has a more visible and more efficient one), and the hull is a little more navigable. But the key here is a bit. However - even quite punts 755 - go across the oceans, even with marines. The main thing is not to fall into the storm, it will be like on Indra - to postpone exercises for a week.

You also need to keep in mind that inside it is empty, the hangar for the payload, so the center of gravity is high, hence the problems. Of course, ballast tanks and all that, but there are problems. And do not forget when it was designed. “Back in those days,” they really didn’t know whether they would give money for the construction or cut it directly on the slipway. “Novik” was never built, but there were conversations ...

[Grits]

What were the designers thinking?
Designers were very visionary people. They already knew then that they would have to drive him along the Dnieper and then land troops on the coast of Kazakhstan in the Caspian.

[Bronevick]

Real men do not include the back. It is necessary to cut it already, let the metal into the frigates.

[Wolka]

sorry, very sorry, but the sea does not forgive mistakes ...

[senima56]

The “Reverse Problem” and the “Reverse Control Problem” are two big differences! Although I agree, “Problems” must be solved in any case!

When the last tests are completed, it will already be safe to send to scrap metal ...

[sapporo1959]

Well, metal is now in price so we won’t lose any.

I blinded him from what was.
