Blind from two halves. The French Navy has figured out how to save the burned out nuclear submarine

Break and glue



French Defense Minister Florence Parly confirmed on October 22 that the Perle nuclear submarine, which caught fire on June 12 during a major overhaul, will not be decommissioned, as predicted by all practically experts, but will be restored. The solution proposed by the Naval Group specialists, on the one hand, is original, and on the other, not very good. The bow of the ship burned out completely, this is clearly evidenced by photos and videos from the board. Probably, we are talking about the first and second compartments of the ship - the torpedo compartment and the central post compartment. There, there was no chance of recovery at all - 14 hours of fire was enough for both burnout and a fatal change in the properties of steel. For example, armored vehicles are written off even after a brief but high-temperature fire, during which the flame touched the armor for a certain time. And here - a boat, which has to "dive" hundreds of meters. Even if it is the smallest combat nuclear submarine in the world (less in displacement even of our Lear), and not the most successful, but still a nuclear submarine.



S606 Perle after fire

Obviously, the fire did not go into the third compartment (the reactor echelon) and beyond. And it was decided to keep this aft part of the boat. And the burnt nose will be cut off and disposed of. And in its place will be welded the nose of the first disabled nuclear submarine of the Rubis-Saphir type, which was disabled and written off a little over a year ago. After reconnecting the halves, all piping, cables and other connections will be restored. "After that, Perle will continue the major renovation that was interrupted by the fire," said Florence Parley. The operation of cutting off the burned-out half, cutting off the other half from the decommissioned boat and connecting it to the aft part of the "fire-place" will take about six months. And after that, the nuclear submarine will continue the overhaul, which will last until the end of 2023. Moreover, the equipment in the new old bow section will have to be replaced with the equipment that was removed from the "fire site" during the repair - thanks to this it survived. These are elements of torpedo armament, sonar complex, electronics, pumps and others.

Is there any reason?


Why is this done? But because the boat from which they will take the bow is the second nuclear submarine of this project, laid down in 1979 and entered service in 1984. That is, the ship has served 35 years, and, of course, all its equipment, despite repairs and replacement, already quite old. But Perle - the last built boat of the project (there were two more, but their construction was canceled), was laid in 1987, and put into operation in July 1993, everything there, of course, is newer and livelier. Although, on the other hand, the ancestor of the class, Rubis, is still formally in the ranks, despite the fact that it was laid down in 1976, and put into operation in 1983. True, the presence of this submarine in the ranks is formally, it was already going to be disarmed and disassembled in 2017. Then, in view of the constantly postponed entry into service of the lead nuclear submarine of the new Suffren project, it was postponed to 2018, then again and again, and now the decommissioning is scheduled for the end of this year. And it is possible that the date will be postponed again - after all, Suffren will not even formally enter service this year.


And this is how Perle looked in the ranks

The returned Perle is expected to serve until the end of the decade and be replaced by the last of its classmates on a Suffren-class nuclear submarine. The restoration procedure itself was chosen because, as reported, it is required to keep the numerical strength of the French submarine forces at a minimum level.

There is nothing new under the sun


The procedure itself, conceived with the "Pearl" (the whole series of these nuclear submarines is named after the stones: "Ruby", "Sapphire", "Emerald", "Amethyst", the exception is the "Casabianca" nuclear submarine), in general, not news in world shipbuilding. Lovers stories fleet can recall similar operations in the American Navy during the war, and our cruiser Molotov of Project 26bis, to which instead of the badly damaged one they welded the stern of a cruiser of another Project 68, and it served then for another quarter of a century. But a surface ship is one thing, and a submarine is another. And it's one thing to take the stern of a new unfinished ship, and another thing to take the bow of a boat that has served 35 years and was written off, taken, in fact, from a landfill (well, of course, it did not end up in a landfill). Yet, despite the replacement of equipment, the old ship is the old ship. Will it not turn out that the "Pearl" will be the same "dead soul" as the "Rubin" in recent years, when the boat was constantly stuck out either in repairs or at the pier? It may very well be.

But, apparently, the French admirals do not want to stay with 4 nuclear submarines instead of 5. And there are many reasons. Even after entering service, Suffren will be healed for the first years from the diseases of the lead ship. Ruby will be decommissioned. Cases with the reliability of the other three "rubies" are also not very good. Even when all 6 "rubies" were in service, usually there were actually 2, then 3 boats, then 4. And then you will grab even for such ambiguous options as the restoration of Perle. And then new nuclear submarines of the "Barracuda" (Suffren) type are being built terribly slowly and with constant time shifts. The ancestor of the class, for example, was founded back in 2007, and will enter service in 2021, the next one, "Duge-Truin", was laid in 2009, and it will most likely enter service in 2023, and so further, that is, the construction period turns out to be from 12 to 14 years, for a small, 5300 tons, nuclear submarine, to put it mildly, without technological miracles and breakthroughs. And the deadlines can "float" further, and the combat readiness of the "rubies" - to fall even more.

There is one more point: the fewer boats remain in the ranks, the narrower the possibilities of a bureaucratic nature. A division of 5-6 submarines is one thing, and 3-4 is another. They can also change the status of the submarine squadron, and change the commander's staff category. And so, formally, there will be 5 boats, and how many of them are actually in service is the tenth thing. And again, a similar approach is characteristic, probably, of many fleets, not excluding ours. At one time, the B-380 submarine of project 641B was formally retained in the ranks of the Red Banner Black Sea Fleet (KCHF). Which, back in 1991, was put up against the wall for overhaul, which eventually began only in 2000. And which did not go wobbly or roll (at times really did) until the beginning of this decade. So far, they have not given up spending money on a morally and technically outdated submarine.

And then there was a return of Crimea home, the newest submarines of pr. 06363 began to massively enter into operation of the KChF, the only combat-ready submarine of the KChF "Alrosa" B-871 went into repairs, but they forgot about the B-380. Although they made plans to dispose of it, they were no less zealous than before to turn it into a training ship. But the boat continued to occupy the ancient floating dock PD-16, together with which it sank at the end of last year, then surfaced and finally got to disposal. As they say, the whole saga with the B-380 was not only for the sake of writing off money for work on it, but for the sake of something else: being in repair of the second submarine made it possible to keep a division of submarines with the corresponding positions in the KChF.

There is one more thing - financial. The work on cutting the "halves" from the decommissioned and burned out boats and on their reunification will not be cheap. According to French media reports, the renovation costs are estimated at around 120 million euros, or $ 140 million. According to Le Monde, the French Ministry of Defense will pay 70 million euros, and 50 million euros will be covered by insurance payments. The amount is substantial, and it can increase even more, and there is still an amount for the overhaul itself. Writing off with disposal certainly does not cost that kind of money, which means that the Naval Group had a reason to persuade the French Ministry of Defense for such an operation, even if experts consider this operation pointless.

Time, however, will tell what will come of it.

            The overall longitudinal strength is normally ensured in large block assembly. Ships extend by welding insert. There is a bigger problem in the metal fatigue of the old boat and the coincidence of the set beams, as well as the skin sheets. And if for a surface ship this is even more or less acceptable, then for a submarine ... You can see that the guys with the money are strained.

              What is the longitudinal strength? if the bow is welded to the power set (structures) of the stern. What will be the strength in the welds? If initially the whole structure was one-piece - from the bow to the stern perpendicular.

                In fact, it was not solid. The boat was all-welded. And it had the same welds that it would have after the renovation. A high-quality welded seam with the required leg gives an equal strength connection. The quality of the weld is checked by non-destructive testing such as gamma-graphing or X-ray diffraction.

            By the depth of immersion (if the boat will survive before going out to sea), restrictions will be introduced and that's it.
            A couple of boat-length rails are thrown on the floor, so longitudinal "strength" is, and it will be convenient to push the trolleys with coal :)

        It doesn't even matter how long it takes. And yes, it will take a lot of money too. But they take care of their fleet.

        However, I would like to note below what upset me against the background of this news request Nobody else thought about it, I wonder? ..

        They restore a burnt-out old vessel to the trash, and we have almost new (well, or comparable in age and without fires) hulls sawing for scrap. No otkapitalit, and in operation ... And then we cry that there are not enough submarines.
        I understand the pain and cost of upgrades, but it's better than being left without a submarine fleet ...
        And, it turns out, it may be different!

      I personally doubt that this submarine will dive at all. The French Admirals are also not fools and they are not suicidal in repeating our Kursk.
      They nada that there would be a "beautiful number" that will be .... and the same nose can be cut off and welded for at least 10 years. But even the modernization remains, but even if a miracle happens and the nose is welded on to another, then the boat is modernized, there is still a whole series of tests and a couple of dozen commissions about whether this brainchild of the French Frankinstein can swim or not.
      This saga will stretch for years ... which is exactly what the admirals need, and then they will quietly write off the submarine.

    At one time, the B-380 submarine of project 641B was formally kept in the ranks of the Red Banner Black Sea Fleet (KChF). Which, back in 1991, was put up against the wall for overhaul, which eventually began only in 2000. And which did not go shaky or roll (at times actually went) until the beginning of this decade. Until they refused to spend money on a morally and technically outdated submarine. And then the Crimea returned home, the newest submarines of pr. 06363 began to enter the KCHF en masse, the only combat-ready submarine KCHF "Alrosa" B-871 went into repair, and about The B-380 has been forgotten. Although they made plans for its disposal, no less zealous than before turning it into a training ship. But the boat continued to occupy the ancient floating dock PD-16, together with which it sank at the end of last year, then surfaced and finally got to disposal. As they say, the whole epic with the B-380 was not only for the sake of writing off money for work on it, but for the sake of something else: being in repair of the second submarine made it possible to keep a division of submarines with the corresponding positions in the KChF.

    Floating dock PD-16 was accepted into the Navy in July 1941. It was so old that no one in Sevastopol remembered the days when this dock was not in the bay. Everyone has long forgotten the dock's pedigree. Old-timers told with blue eyes that the "sixteenth" is generally "a trophy that we transferred here from Germany after the war." De facto, for the last 10 years, abandoned and rusted wherever he could (and he could in many places), the dock kept on the water exclusively through the holy spirit and also by the law of Archimedes. Now about the boat of project 641B B-380, aka "Gorky Komsomolets", aka "Holy Prince George", which has been rusting without getting out of the way in overhaul since 1991. Nobody needed this antiques in the Black Sea Fleet for a long time, but with its decommissioning the 247th separate submarine division remained with only one submarine B-871 "Alrosa", which naturally put on the agenda the question of why the Black Sea Fleet needed an integral submarine division with the corresponding organizational structure and a crowd of l / s, if there is only one submarine in that division? That is why the B-380 has been “repaired” for a lot of years in you know what dock, and its crew, meanwhile, went to sea on the Alrosa. The situation changed only in 2014, when new diesel-electric submarines of project 636 went to the KChF from the Baltic, which allowed the division to victoriously deploy into the 4th separate submarine brigade and, finally, finally hammer the bolt on the B-380. By that time, the latter had already firmly become attached to PD-16, from which only the rusted fence of the "deceased's" cabin with a pathetic St. Andrew's flag fluttering in the wind was sticking out. The tender from the Ministry of Defense of the Russian Federation for the disposal of the B-380 was announced on April 29, 2016, but the hands did not reach its implementation ... In the end, the dock lay on the ground, but the upper deck of the dock remained above the water. Under the dock, the depth of the site was only 14 meters, since the dock, which was in a semi-emergency state, was specially held above a shallow place. The submarine B-380 of project 641b, decommissioned from the fleet and put up for a scrappage tender, which has been in the dock for many years, remained afloat when the dock was flooded, but turned over on its side.

    Analytics from Vyatkin - we rewrite an article from Defense News with the help of a Google translator and add arguments about the fear of French admirals for their place, which have nothing to do with the topic.

    In 2005, the USS San Francisco nuclear submarine crashed into a seamount at full speed.
    The Americans used the bow of the same type USS Honolulu, decommissioned by installing it in San Francisco. The submarine served eight more years without any restrictions.
    The renovation cost was $ 134 million.

    I read the comments. Everything is as always, the only thing, no one remembered about Putin :) Strange :)
    And what is interesting, no one paid attention to the information on the timing of the construction of the French planes of the new series: "It was laid in 2007, launching - in 2021, if it is launched." And then - the long-term elimination of "childhood diseases"
    And how these same commentators (already from the first words I began to recognize them) are exasperated about the timing of the construction of Ash trees !!! Why are we silent here?
    It turns out that in the "advanced" countries, entirely inhabited by light-faced and tolerant people, not everything is simple. But in France there was no perestroika / shootout, total destruction of the shipbuilding industry and the system of training for it!
