Rescue ship

FIELD: transport.

SUBSTANCE: invention relates to rescue ships. The rescue ship is designed for wrecking of sunken submarines and equipped with air feed appliances, divers' and other standard tools. The ship represents a submarine furnished with a set of tie-down cables, including a cable loop, and cables ensuring its reliable holding at a distance of about 10 meters above the sunken submarine. It has, also, two bottom hatches, one of them being communicated, via an air-lock, with several pressure chambers with exits into the submarine. The second hatch, furnished also with the air-lock communicating with one pressure chamber, can be provided with tightly mounted adapter unit, fastened from both inside and outside, to be tightly mounted on appropriate hatch of the sunken submarine and likely fastened from both inside and outside it.

EFFECT: possibility of rescue operations in rough sea.

There are various designs specially equipped vessels for rescue operations during the rescue operations on submerged submarines (see, for example, "RESCUE of PROPERTY AND FUNDS of the NAVY", Moscow, Military publishing house, 2004).

They are all surface ships equipped with special devices for carrying out rescue operations.

Rescue operations begin after the arrival of the rescue vessel (SS) in the area of the accident, placing it directly over the sunken boat and possible fixing it in this position. Then in a specially equipped rescue compartments emergency DPS with rescue vessel can be served fresh air and electricity through the air ducts and cables, drop with SS and attachable to the special connectors, which are mounted in rescue compartments.

To attempt the ascent emergency PL apply the high pressure (working pressure 20 MPa) type TVD-P1, with which it is possible pumping ballast tanks emergency PL.

For a possible evacuation of the crew of the SS may have the rescue device ("bell")installed on one of the hatches emergency PL.

Despite the diversity of structures of different equipment SS when performing sposate is lnyh work any of them have the following disadvantages:

1. Impossible to get a reliable fixation surface vessel (especially when the sea is rough) relatively motionless lying on the depth alarm SQ. The greater the depth, the greater the drift SS around the SQUARE and the greater must be the stock length of the pipelines, etc.

2. The rescue operation is only possible when sea waves are small.

3. The depth at which a SUBMARINE can be helped, is strictly limited. (The length of the lines, pipes, cables etc. not exceeding 300 m Maximum pipe length TVD-R five sections - 342 m). With regard to claim 1 real help DPS can be provided at a depth of no more than 200 meters

4. Quite time-consuming and delivery ends of the cables, pipelines and cables, re-entry with the SS, to the place of their installation and connection of all these elements to PL is carried out by divers, which time (with respect to time dives and surfacing with exposure to decompression) limited to a few minutes.

5. In the presence of bottom currents, sea state and other certain tasks becomes almost impossible (recall, for example, multi-day attempts to establish a rescue bell on the hatch of the 9th compartment of the KURSK...).

6. Only blowing high pressure air ballast tanks cannot always ensure the ascent of the boat. Part of the compartments can be flooded is. Blowing air is not provided. The possibility of ascent depends on the position of the boat on the ground, its characteristics, etc. in Addition to blowing high pressure air ballast tanks other opportunities for raising today's rescuers not.

To eliminate the above disadvantages of the proposed rescue vessel for emergency submarines to do based on a specially-equipped submarine. Moreover, the conversion does not require complex design changes, and will mostly refer to only install on the boat special tools rescue vessel. All rescue operations can be carried out almost in the same way.

Example implementation:

One important advantage of this proposal is the ability to avoid high costs and instead of expensive construction special crew rescue vehicle to use for the decommissioned military submarine (preferably larger). A schematic representation of additional equipment for conversion into a combat submarine rescue shown in figure 1.

Refitting boats is to remove the weapons and the installation of two nodes: the diving and rescue, each of which has at the bottom of the boat sealed the hatch for entry and exit.

The FIRST hatch (diving - 2) via the gateway 3 is connected with the NESCO is Kimi (1-2-3) of the pressure chambers 4, in which the divers are on the way and where to come back after work to decompress. This will significantly increase the actual working time, will allow you to simultaneously (or sequentially) to work with multiple teams of divers, significantly increase the time and improve the safety of their work through the necessary gradual, regulated by time pressure changes directly in the chamber.

With the approach of the boats rescue and installing it over emergency PL divers attach the ends of the several cables 10 to the housing emergency boats and (individual) their tension provide the required relative positions of the boats with high precision at a given distance from each other. The necessary tension on the cables is provided by blowing ballast tanks of a submarine rescue. Especially hard mutual fixation is performed in the area of installation of the transition chamber to ensure its integrity.

To the SECOND receiving slot 5 through the lock chamber 7 with the pressure chamber 8, which is tightly attached transition compartment 6, which can tightly connected with one of the top hatches 9 emergency SQ. This allows reliable installation of the transition chamber divers simultaneously inside and out, ensuring accurate installation, reliable fastening and garantirovannosti connection.

Schematic illustration of the relative positioning of the rescue and emergency DPS in the process of conducting rescue operations shown in figure 2.

All rescue operations can be carried out after a preliminary reconnaissance, during which define the required number, size and position fixing of the cables 10. Then, in the surface position on the boat-rescue fixed locking cables and hermetically set transition compartment 6. Boat rescue is located above the emergency SQ. (If necessary to install the lifeguard on emergency PL can be used tether loop. see below, figure 3).

Several groups of divers through the chamber 4 and 8 and lock the compartments 2 and 5 landed on the emergency PL and fix the ends of the powerful cables 10 to the housing crash SQ. Thus the " rescue " boat moored to emergency several strong ropes.

Election tension (if necessary) carry out of mutual alignment, then (by blowing ballast boats rescue and, due to this, the necessary tension cables) almost hard mutual fixation. In the area of installation of the transition compartment may establish special rods for coarse relative fixation. Then the divers on the outside and the inside is sealed installation and Zack is Alenia on the top hatch 9 emergency PL transition compartment 6 and the pumping out of him and airlock compartment 7 of the water.

The exit hatch 5 and return to him divers is made through a lock compartment 7 and is connected with a pressure chamber 8. After this mutual efforts of the crews of rescue and emergency boat hatch opens 9 emergency boats.

The transition from boat to boat through the transition compartment is dry.

Made (if necessary) the evacuation of the crew emergency PL or her seconded specialists (with the necessary spare parts) for emergency response.

Rescue ship has the ability to without a crew evacuation emergency PL (in the presence of inserts by PATENT 45930) to enter with its members (in any of the compartments in telephone contact and better concerted action (simultaneous blowing ballast tanks, draining of flooded compartments and the like), as well as using their engines to make the gap from the bottom, lifting or transportation emergency SUBMARINE on the surface or at shallow depth.

The number and placement of the cables 10 to the boat hull rescuer (as well as the determination of their initial length) is carried out after examining the provisions of the emergency boats on the ground, and installing them on the boat hull rescue is on the ocean surface, which significantly reduces the work of the divers.

As one of the options on the housing rescue can be installed auxiliary cable loop is oblegcheniya fixation over the emergency rescue boat (for example, in the case of strong bottom currents).

Examples of usage of the loop shown in figure 3.

The length of the cables 10, after fastening their ends on the housing emergency submarine, may be subject to various known ways to achieve the same tension when pdfsplit" boat rescue at the installation position of the transition compartment.

The advantages of THIS INVENTION are:

1. Rescue boat can be recorded on the emergency at a relatively short distance (about 10 m), with much accuracy is guaranteed by the placement of cables, and a small distance and guaranteed tension by blowing ballast moored boats rescue allows you to make the mounting a floor, or even hard with all the attendant advantages.

2. The sea state will not interfere with the rescue operations.

3. The depth at which you can rescue operations, will not have such strict restrictions (for example, the length of pipelines and cables) and can be significantly increased.

4. Installation and connection (shortened more than 30 times) pipelines and cables to the emergency DPS greatly simplified.

5. Time divers due to the decompression chamber significantly increases

6. Small the distance is between the boats allows you to set the "from hatch to hatch" transition compartment for evacuating crew "dry" and directions to the emergency boat specialists to conduct a qualified repair.

7. If emergency PL inserts under the PATENT 45930 all flooded compartments can be drained, crew members, cut off from rescue compartments, receive prompt assistance in the form of clean air, electricity and telephone communications with the rest of the crew and rescuers.

8. The total time of rescue operations is greatly reduced.

9. For the separation of the emergency boats from the ground, lifting her and even possible transport to a small depth (in addition to pumping ballast tanks and draining of flooded compartments high pressure air) can be used in the engines and rudders boat rescue, is particularly effective in dynamic mode.

10. The conversion of decommissioned military boats in rescue will save enormous resources (in comparison with the construction of a rescue vessel, which was planned according to the type of foreign, after the death of the "KURSK").

Rescue vessel designed for carrying out rescue operations on submerged submarines, equipped with air supply and electricity, diving, and other standard equipment, characterized in that it is made on the basis of a submarine that has a set of ropes for mooring (including cable loop) and firmly at a distance of about 10 m above the emergency submarine and two hatches in the bottom of the first of which is connected through the lock chamber in parallel with multiple pressure chambers, having access to the inside of the boat rescue, and the second hatch, which also lock chamber connected to one pressure chamber, may be tightly mounted and secured from inside and outside the transitional device, hermetically installed and fixed (also inside and outside) on the corresponding upper hatch emergency boats.
