Military Review

The scheme of the possible rise of the Norwegian frigate Helge Ingstad is presented.

45
More than three weeks have passed since the collision of the frigate of the Norwegian Navy "Helge Ingstad" class "Fridtjof Nansen" with the tanker "Sola TS". A Luxembourg-based Gulliver floating crane with a carrying capacity of 4 thousand tons approached the site of the sinking of a warship in the area of ​​Bergen. In this case, the operation to lift the frigate has not yet begun.


In the Norwegian Navy, together with representatives of the Belgian-Luxembourg company Jan De Nul, which owns Gulliver, they are discussing possible measures to raise a submerged warship that could not disperse from the said tanker, having received a hole below the waterline.

Earlier, the Norwegian Navy made claims to the Spanish manufacturer of frigates of this type. The claims were that the frigates are created with a level of survivability, which is significantly lower than stated. The flooding of the “Helge Ingstad” is given as an example, although damage was received to one of its compartments. The Spaniards, in response, say that the critical roll of the ship is to blame, which ultimately led to the frigate "sipping" water.

One of the proposals under discussion is to evacuate water from the internal compartments of a submerged frigate fixed off the coast, reducing its total weight. This is necessary so that the “Gulliver”, in terms of its carrying capacity, could at least begin to lift the “Helge Ingstad”. Recall that the displacement of the Norwegian frigate is almost 5,3 thousand tons. The scheme of possible works is presented.

The scheme of the possible rise of the Norwegian frigate Helge Ingstad is presented.


The next stage should be the underwater alignment of the combat ship with the help of the arrows of the same “Gulliver”. As soon as the alignment takes place, the main lifting phase will begin.

In this case, the question arises whether Helge Ingstad will not pull that Luxembourg floating crane, whose carrying capacity is lower than the frigate's displacement, to the bottom?



The developers of the lifting plan, naturally, preoccupied themselves with this problem and suggested the following: bring special pontoons under the “Gulliver”, which will add buoyancy to it (marked with a reddish tinge). Then the pontoons can be used for the raised frigate of the Norwegian Navy - for further transportation to the port. This kind of scheme is presented on navaltoday.com.

Experts note that the weather, which has been established in the area of ​​the frigate’s flooding, is preventing the process from starting. Strong wind and rough seas significantly complicate the Helge Ingstad lifting operation. But if the process is delayed, then the winter weather may deteriorate completely, and the process will have to be postponed until spring, which may affect the condition of the flooded ship.

        The main thing now is “Gulliver” is not left there, the calculations should be most accurate otherwise ..... smile

      So here ... I somehow "perpendicular and parallel" how and what they will do with this "drowned man". Hopefully "many thanks" to the US Navy trainees they've already said. And as the experience of history says, they are unlikely to restore this ship, most likely they will raise and send it to the "needles".
      But here is the story with our dock, I really care. If only they showed how they plan his rise, in order to understand what fate is destined for him

          This can happen solely due to any qualifications of the navigators, or due to the presence of "interfering factors" on the bridge. In the form of superfluous people and strangers. There was a photo from the bridge of this "frehat", there were 10 people on the bridge, incl. some kind of hell in an American "sand" camouflage.

              Well, like this. It’s best when there are two people on the bridge - quietly, calmly, and don’t think about anything outside. When there is also a steering superprofit - you don’t even need to command, everyone knows what he should do and controls the other. In difficult cases, the captain is called, but the normal captain comes to the bridge exactly what to help, and not to do it your own way.
              Damn, but how stressful it is when a bunch of strangers! Especially when they are trying to communicate.

        The dock is old and probably rotted especially in the waterline zone. They will try to cut off the extreme pontoons, as the most rotted ones. If you can close the kingstones, in other pontoons, pump out the water and the dock will pop up, if there is no paddle land, it’s scrap metal. The dock will be reduced by 50-70 meters with a loss of capacity. The fate of the dock and kuzi is unenviable.

        For there is nothing to fly from it ((and we have no "radars" or refuellers "And without this" avik "is no better than a missile cruiser ((. The meaning of the American AUG (their strength) is just" radars "- they" expand the "radio gorichont" for the entire grouping. And our "Kuznetsov" is just a floating airfield ((which even a normally heavy fighter cannot accept (the cables burst).

      Well, considering that it is still not on the sand and now there is no "summer breeze" - it is cheaper to "push" it into the abyss. After all, besides the fact that everything there was ditched by sea water, it was also clearly jerked against the sharpest stones. Obviously, the rise will be more expensive than the price of scrap metal that will be given for it. ))

    start the process is prevented by the weather, which was established in the area of ​​flooding of the frigate. Strong winds and sea waves significantly complicate the Helge Ingstad lift operation.
    The frigate sank in an uncomfortable place. Although it lies almost on an even keel and shallow depth, the climb can be problematic due to the weather. Floating cranes really do not like wind and pitching, and this is what is happening now. The proximity of the coast and the steep rocky dump prevent pontoons from being built. In my opinion, FIG, they will raise it until spring.

    Is it really possible to pump water from a flooded ship? belay
    I would also agree if some kind of "bubbles" made of airtight material were installed in the holds or some other premises and pumped up, increasing the lifting force, but pumping out water just like that? what
    Well, or at least fix the ends of the outer pontoons and choose those ends using ebbs and flows, quietly, pulling them into a shallower space and already there, stopping holes to start pumping out water and raising the ship
    After all, if he sank, then the water can easily get where it wants and pumping water is essentially useless? Or do they want to pump the sea? recourse
    Oh, entertainers !! At first they created a difficulty for themselves, now they overcome it, and now Russian submarines go by their side, just like at home !!! wassat laughing

      Alexey hi the compartment is sealed, and water is pumped out of it, and so it is pumped out of the entire hold, the air is inflated into empty compartments, and, at least, the ship comes off the bottom, or it floats up.

      From the fuel tanks they pump fuel to the 02.12.2018, there are 250cubes left. Now the weather is in the way.
      Before Christmas they will not have time to raise, then winter.

      Why did you sink so quickly, so it depressurized the starboard side almost to the transom, plus the crew were evacuated rather than fighting for survivability. There, almost all the watertight doors were open.

    Sometimes it’s more advisable to write off than to lift. At the moment, even the norgs claim that a number of critical systems of the ship were too long under water and would need replacing. This has not yet been properly explored the hull and the volume of restoration work is not clear after it was carried down to the pebbles to a depth.

    In this case, the question arises whether Helge Ingstad will not pull that Luxembourg floating crane, whose carrying capacity is lower than the frigate's displacement, to the bottom?

    Counter question: what, it was impossible to find another floating crane, the carrying capacity of which is MORE than the displacement of the frigate?
    Remember how the Kursk was raised? And there will be more displacement.

    It is always more difficult to lift large vessels from shallow depths than from large ones. I don’t remember why, but at one time there was a book about ship lifting, it was called, in my opinion, "Underwater Master's Affairs" (not exactly), that's where it was said in detail about all the problems. And of course they will lift either the frigate or what will remain of it by the spring.
