The rescue equipment of the submariner "SSP-M" will be adopted by the end of the year.

The Russian Navy will receive for service a new rescue equipment of the submariner SSP-M, which allows it to work at a depth of up to 220 meters, reports TASS message from the representative fleet Igor Dygalo.

It is planned that by the end of 2018, the newest rescue equipment of the submarine SSP-M will be adopted by the Navy. The equipment has been tested in laboratory and marine conditions - more than 500 descents have been carried out,

said Dygalo.

He noted that "the equipment will allow to provide rescue from the depths to 220 meters using the free ascent method."

According to the representative of the Navy, "in 2017-2018, during the exercise in the Novorossiysk naval base, the element of the escape through the torpedo apparatus of the conventional submarine of the experimental group of the institute consisting of six people was worked out using the SSP-M rescue equipment." Before that, the equipment was tested on the basis of the Scientific Research Institute for Rescue and Underwater Technologies in the city of Lomonosov.

Crews of nuclear and diesel-electric submarines of the 4 generation will be equipped with new equipment.

The advantage of the SSP-M rescue equipment over the existing SSP equipment is the possibility of using it without a breathing apparatus when exiting the emergency submarine due to the sealed “hood” in the SSP-M configuration,

he specified.

In addition, “in the new equipment there is no parachute system, which previously provided braking for the free ascent of the submariner and had impressive dimensions,” added Dygalo.

The submariner's safety of safety is ensured by increasing the speed of compression and the speed of free ascent, which minimizes the time spent by the rescued under increased pressure,

he said.

Equipment is a development of the Russian company "KAMPO". It “allows us to leave the emergency submarine not only through the rescue hatch, but also through other sluice devices, the Navy representative said.

... You yourself answered at the beginning of the question

"The safety of rescue of the submariner is ensured by increasing the compression speed and the speed of free ascent, which minimizes the time spent by the rescued under high pressure,

... That is, nitrogen does not have time to bubble up and block the vessels.

[semenoffdima]

Yeah. It will bubble already on the surface when the submariner breathes a sigh of relief. In general, there are a lot of mistakes in the article. To begin with, when leaving a sunken submarine, the submariners are already under high pressure. If the boat is dry and the pressure in the hull is 1 atm, then, when reaching a depth of 220, the submariner is likely to “squeeze” well with a sharply increased pressure. In short - some nonsense, not an article

/// when reaching a depth of 220 submariners, most likely, not bad, "crush" sharply increased pressure.

... Surely ... That's about the enemy counterpart that they write .... Well, there’s nowhere to go :

Currently, the following types of individual rescue equipment for submariners (AISS) are used in the Navy of the NATO countries: - type SEIS Mk 8 (Submarine Escape and Immersion Suit) manufactured by the English company Beaufort Air-Sea Equipment Ltd (Beaufort Air-Sea Equipment Ltd), which are equipped with naval submarines of Canada, Italy, the Netherlands, and Norway (submarines of the Cobben type);
- type SEIE Mk 10 (Submarine Escape and Immersion Equipment) of the same English company - on submarines of the Navy of Great Britain and Norway (submarine of type "Ula");
- type SPES (Submarine Personnel Escape System) Mk 10 of the German company “bfa See- und Luftausrustung” - on the submarines of the Navy of Germany and Denmark;
- such as American-made Stemke Hood - on submarines of the US Navy, Turkey and Spain;
- type URK 80 of the German company "bfa See- und Luftausrustung" - on a submarine of the Greek Navy;
The Polish submarine of project 877E is equipped with ISPPs of Russian production of the ISP-60 type.
ISIS type SEIS Mk 8 is the most common in the world. It was taken to supply the Navy of 22 countries. In July 1987, a group of English, Norwegian and Swedish submariners tested this equipment in Björnfjord (Norway), during which several consecutive exits from the emergency rescue hatch (ASL) of the British submarine Otus test took place. The tests began from a depth of 30 m At a depth of 90 m, some of their participants could not continue the experiment. Only two people exited from a depth of 183m.

SEIE suit for exiting emergency submarines, to a depth of 183 meters, at a speed of up to three meters per second, rule evacuation number: "never hold your breath."

QUOTE: "... Only two people exited from the depth of 183m." - And in the article we are talking about 220 meters, with the compression mode in the rescue hatch doubling the depth every 4 seconds. Even a very well-trained deep-sea diver will not be able to undergo such compression without ear barotrauma. What about the submariner? Who will wait on the surface for this large, bleeding barotrauma, which has lost its mind from pain, to get it out of the water and provide specialized medical care? “After all, without immediate help he will perish.” The worst part is that everyone understands all this! But rescue ships of submarines do not want to build anyway.

[san4es]

... And the oxygen-helium mixture in the apparatus will not save the situation?

[water]

I think it will aggravate. After all, helium is very thermally conductive. It will cool the nasopharynx, the tissues will shrink, and the passage sections will decrease.

[annodomene]

So it’s in the apparatus, and not an oxygen-helium mixture, but pure helium from DHB (when leaving a depth of more than 120 m). True, DHBs are not stored on the pl due to the high yield strength of He. Transmitted to submarines with SS.
You can go out without the apparatus, but here the speed of pressure equalization with the outboard and the time the submarine is under pressure in the square are of great importance. I can’t say more precisely, because not familiar with TTX and the device of a new hood ...

[annodomene]

As stated in the classic textbooks on diving business - with free ascent, in no case do not hold your breath. Usually this happens on one long "aaaaaaaaaaaaaaaaaaaaaaaa" to the surface. It is possible to avoid BT of the lungs. It is more difficult with the ears, but when the membrane breaks, it is a second pain, then it’s normal.

[annodomene]

"Sharply flatten" the submariner in the lock device. The speed of pressure equalization with outboard is approximately 6 kgf per sq. cm per minute. Feeling quite tolerable.

[water]

With the speed of compression, you are somewhat mistaken. In order to protect against the caisson, during compression (equalizing the pressure with the outboard), the pressure doubles every 4 seconds. I explain: 4 seconds have passed and the submariner is already at 10 meters, 8 seconds - 30 meters, 12 seconds - 60 meters, 16 seconds - 120 meters, 20 seconds - 240 meters.
According to foreign experience, the testers withstood such a rate of pressure rise only to a depth of 183 meters. And then, pre-made perforation in the eardrum. Deeper tests were carried out only in laboratory conditions with preliminary medical and physiological preparation of the testers (perforation in the tympanic membranes, artificial expansion of entrances to the air cavities of the body).
Thus, I would not call these feelings acceptable.

[annodomene]

I repeat once again: in the Navy of the Russian Federation, when using SU and balancing the pressure with the outboard, the rate of increase in pressure 6 of kilogram-force per square centimeter per second is used. What sensations can be understood in this case, if such an imitation is carried out in a pressure chamber. Which was successfully worked out.

So in which of these quotes did you say what you wanted to say?
Indeed, compression at a speed of 6 kg / cm2 per 1 minute is the descent of a well-trained diver in three-bolt equipment underwater. While the compression of 6 kg / cm2 per 1 second is 60 times faster! And I don’t even wish such an enemy.
In general, information on the compression rate (compression program) depending on the output depth is given in the BPV operating instructions.

[san4es]

In June 2017, the SSP-M was successfully tested in marine conditions, in particular, an exit element was worked out through a torpedo tube of a conditionally emergency submarine of the Institute's experimental group of six people. The role of the conditionally emergency submarine was played by the diesel-electric submarine of project 636.3 Stary Oskol.

[Ustin]

The bottom time and depth, one thing with forty and the bottom in 10 minutes, most likely nothing will happen to the majority, but with 200? Nitrogen in the tissues will be quite decent for "worsening", if you free floating, then in any way you’ll have five minutes get to the surface at 40 meters per minute. It seems that the matter is not only in the speed of ascent.

[san4es]

Quote: Ustin

... It seems that the matter is not only in the speed of ascent.

... Maybe it's a miracle hood and pressure inside the suit?

[semenoffdima]

And what could be in the "miracle hood" that violates the laws of physiology?
Pressure inside the suit - what? Even more elevated than the outside? Then - an unequivocal submariner. Lowered? - then crimp and death by suffocation.

[annodomene]

During compression (before the opening of the upper hatch), the pressure in the SGPK and under the hood and “in the submariner” will be compared with the outboard. When leaving, it will decrease. See diving case books, free ascent method.

[semenoffdima]

I don’t even know what could be there. If only in a suit instead of air - heliox? Then, putting on a suit and breathing them a dozen minutes - you can, in principle, reduce the amount of nitrogen in the blood.

[annodomene]

Once again I repeat: from 200 meters (20 kgf excess) the pressure equalization time to 20 kgf is approximately 3,33 min (6 kgf per minute). It is not enough for saturation with nitrogen, subject to an early subsequent exit, i.e. reduction of excess pressure.

[water]

My friend! Do not mislead people. Because the physiology of scuba diving does not ambiguously tell us that if you try to dive to 3,33 meters in 200 minutes, then you will fall asleep at a depth of 120-130 meters under the influence of nitrogen anesthesia and your sleeping body will reach a depth of 200 meters. However, according to the conditions for using the equipment, which we are talking about here, having reached a depth of 200 meters, your sleeping body will go up, free ascent, at a speed of about 4,5 meters per second. There is no doubt that it will reach the water surface not already sleeping, but dead. This will be called explosive decompression sickness.

Alive, but stunned and bleeding, it will only be if the depth in 200 meters you reach seconds in 18. Not minutes - seconds!

[annodomene]

But no one, not quite my friend, told you that from 200 meters someone came out either alive or without consequences in the equipment of the SSP. The use of this equipment to exit from this depth is only possible if the forces and means of the MSS are provided on the surface. At least in order to transfer DHB to nuclear submarines, without which the use of equipment at such depths is impossible. Therefore, the real depth for exiting by the free ascent method is 100 meters, according to the buoyrp - up to 120 meters. At the same time, we believe that the pressure in the emergency compartment is equal to atmospheric (plus or minus), which in an emergency situation is unlikely to happen. And nitrogen anesthesia does not occur instantly.

[water]

I would like, though belatedly, but still draw your attention to the fact that the article under discussion is about the SSP-M rescue equipment, which is designed to ensure independent exit of submarines from the compartments of the sunken submarine through rescue devices (rescue hatches ) from depths to 220 meters.
And the exit with free ascent from a depth of up to 100 meters and the exit with diving support from a depth of 120 meters are for equipping the ISP-60 with the IDA-59 apparatus.

[Baltic]

The equipment itself is designed to rescue submariners from depths of up to 220 meters using the free ascent method. The decompression was carried out by means of a parachute system and the composition of the breathing mixture with a low oxygen content. Its second purpose was to exit the emergency boat by buirp through musings. Decompression was carried out due to the number of inspiration and exhalation The equipment is old and reliable. There were inconveniences when rescuing more than 100 meters. The ascent rate was current so that the submariner remained alive. And the ear and nose sinuses were not injured. Judging by the photos, the mask was changed. And some details of the device.

Everything is exactly the opposite: QUICKLY put on the SGPK, QUICKLY take a place in the SS (such as ASL, for example), as quickly as possible to equalize the pressure with the outboard, open the hatch, and begin to exit.

[semenoffdima]

I'm afraid that with such a sharp increase in pressure, the submariner will be so twisted that he is unlikely to act quickly. Pop-ups will be in a “no” state, as cappers cynically say, “collect with spoons and bury in bowlers”.

[annodomene]

6 kgf per sq. cm per minute - still normal, from personal experience

[semenoffdima]

If you have experience and know what to expect and how to prepare for it. And then - I would prefer to avoid such differences, and then the ears of the "bo-bo", and the seals, see - old, they begin to whine. And if we are talking about conscripted conscript? Do you think they are often trained for such pressure surges?

[annodomene]

Around 2005, conscripts did not serve in submarines. Only c / s. And this is "a completely different story ..."

[semenoffdima]

And, well then, yes, the contract soldiers - they are yes, they train every day in the pressure chamber)))

[annodomene]

In order to be resistant to such factors, it is enough to work out the tasks of the joint venture. Plus, on every square there is NLV. So they go ahead of the rest.

1. PP-2 slowed down the ascent rate, with free ascent decompression is not specifically taken into account
2. Exit by buoyrep - when the time spent under excess pressure is exceeded (here decompression is MANDATORY!). Decompression is carried out not by the number of inspirations, but by the TIME of being at a certain depth (see table of decompression when exiting by buirp). By the way, if you don’t have enough brains to remember the decompression mode at the exit, you can simply add up the stopping time at each depth and spend it on triple musing (12 meters of depth). For reference, a trained and calm submariner has 1 minute = 16 breaths.
3. The equipment is old and reliable, IMHO I liked IDA-59 more than IDA-59m, one minus is a slightly increased weight.
4. Indeed, judging by the photo changed the mask, valve box and TPK. In terms of internal structure - alas, I do not know ...
