Description

The invention relates to the field of shipbuilding, in particular to the technique of rescue the crew of an emergency submarine (pl) located on the ground.

The final stage of rescuing people from a pop-up rescue chamber (CWS) after surfacing to the surface is their evacuation to a rescue vessel.

A known system for rescuing a crew from an emergency pl, located on the ground, containing a pop-up rescue camera of a vertical design and a rescue vessel. After the CWS ascends to the surface and the rescue (supplying) vessel arrives, the crew of the emergency vessel from the CWS, which is afloat, goes overboard. Then, the CWS is lifted by a ship crane from the water onto the side of the vessel for the eyebolts designed to install the CWS on the shipyard in the factory. It is proposed that the rescue bell (bathyscaphe) be used in the system to rescue the remaining crew members or inspect the compartments [1] (prototype).

Under favorable weather conditions and normal atmospheric pressure in the emergency compartment, the evacuated from the CWS are evacuated afloat using rescue boats, dinghies, rescue platforms, gangways, gazebos and other marine rescue equipment.

The disadvantage of the prototype is that the escape of the survivors from the SWR afloat in marine conditions is not possible, since the exit sunroof of the SWR with waves above 3 points is flooded. Lifting the SWR from the water with the hook of a ship crane is allowed only without people and is possible in the absence of excitement. For lifting underwater vehicles with people, including a rescue bell, bathyscaphe, ship launching and lifting devices (SPU) are used.

A device is known for preventing flooding of the output hatch of the SWR with a wave in the form of its enclosure for protection against waves of people in the enclosure [2].

A horizontal pop-up rescue camera is known. The CWS is equipped with life support equipment, a guard for the exit hatch, rod devices for lifting the CWS from the water, the lower hatch coaming compatible with the reception and output compartment coaming of the decompression complex of the rescue vessel, and a towing device.

The CWS together with the crew is lifted from the water by a launching and lifting device on board the rescue vessel and installed on the DC air defense coamings instead of the rescue underwater vehicle (SPA) to transfer the rescued to the recreation center and carry out decompression. After the evacuation of the crew, the SWR is launched and towed to the base [3].

The method is an effective solution to the problem of evacuation of the crew from the horizontal swell type, but is not applicable for sub with vertical cameras [1].

The small width of the vertical chamber does not allow placing rod stocks with a base corresponding to the distance between the SPU automatic grippers, which requires the installation of a transverse beam.

A known design of the beam with movable along its length. On the ends of the crosshead, ШУ are installed for connection with automatic captures of SPU. The distance between the automatic traverse grippers is set depending on the base between the rod devices of the lifted object [4].

However, the height of the CWS of a vertical design with an attached traverse does not allow the CWS to be lifted aboard the existing rescue vessels for the purpose of prompt evacuation of those rescued during sea waves.

The objective of the invention is to develop a method for ensuring the evacuation of the crew of an emergency submarine from a swift vertical design crew, which has surfaced in sea conditions, aboard a rescue vessel.

The problem is solved in that in order to ensure the evacuation of the emergency crew from the SWR, which surfaced under sea conditions, rod devices and an exit hatch guard are installed on it, and the control gears are equipped with a traverse with a variable base between automatic captures. The SPU traverse chamber with people is lifted from the water to a height that excludes the relative vertical vibrations of the SWR and the vessel, it is fixed at the fender protection from longitudinal movements, and it is fed to the SWR for the evacuation of the rescued on board the vessel.

The essence of the proposed method lies in the fact that for the evacuation of the emergency crew from the surfaced CWS, a launching device and a ship gangway are used, while the vertical rescue pop-up camera is equipped with lifting rods and the exit hatch guard, and the launching device is equipped with a traverse with a variable base between automatic captures, by means of which the camera is raised from the water to a height that excludes relative vertical vibrations with the vessel, and is fixed at the fender protection against longitudinal s tow-displacement mooring ropes, after which the enclosure serves chamber exit hatch ladder and the ladder evacuated saved aboard rescue vessel.

The usefulness of the distinguishing features is that the way to ensure the evacuation of the emergency crew from the surfaced SWR provides, in comparison with the prototype:

- the safety of the evacuation of those rescued from the CWS afloat when excited by any rescue vessel, the first to arrive in the accident area when it was equipped with an exit hatch guard;

- the safety of landing of rescuers on the KSV or the exit of one or two rescued on the fairing KSV for its sprinkling with automatic captures SPU in the conditions of excitement when the KSV has lifting rods and the guards of the exit hatch;

- the passage of the rescued from the CWS to the side of the ship along the ladder by lifting it to a height that excludes mutual movements with the ship, which increases the safety and speed of rescue during sea waves;

- the possibility of lifting a horizontal chamber from the water to ensure the evacuation of people during unrest, both by the proposed method, and similarly to evacuation from SPA;

- to save and evacuate submariners who remained on the square in the end compartment shelters with the help of SPA.

The invention is illustrated in the figure.

To carry out the evacuation of submariners from the CWS, on the vessel 1, fender protection 2 is installed in the area of the rise of the CWS 3.

Retractable bridge 4 SPU 5 is equipped with cargo pendants 6 with automatic grips 7. Cargo pendants 6 are lowered and lifted by cargo ropes 8. Automatic grips 7 are moved along guide ropes 9. At KSV 3 there is an exit hatch 10 with guard 11, lifting rods 12 and mooring ropes towing device 13.

A traverse 14 is provided for connecting ZA 7 with the lifting rods 12 of the VSWR 14. Rod devices 15 are installed on the upper part of the beam 14 for connecting with the automatic grippers 7 of the load suspension 6. In the lower part of the beam 14, automatic grips 16 are fixed for connecting to the lifting rods 12 of the VSWR. In the traverse 14 there are holes for the passage of the guide ropes 9, which moves the traverse 14 with automatic grips 16.

To prevent longitudinal vibrations of the SWR, mooring and towing ropes 17 are used.

A ladder 18 is provided for the passage of the rescued from the CWS to the deck of the vessel.

Evacuation is provided as follows.

Emergency crew pops up in the SWR to the surface.

With the arrival of a rescue vessel in the accident area, rescue and evacuation of submariners remaining in the terminal compartments of the square will be organized with the help of a spa if their transfer to the SWR is not possible.

At the same time, rescuers are carrying out work to evacuate people from the CWS to a rescue vessel.

To protect themselves from waves, the rescued raise the guard 11 of the exit hatch 10. Rescuers are planted on the KSV 3 and moor it in the area of the crane protection 2.

Guide ropes 9 SPU 5 are connected to the SHU 15 traverse 14, stored in a regular place, and set the mode of constant tension of the ropes 9. Cargo ropes 8 along the guide ropes 9 lower the suspension 6 until the automatic grippers 7 are connected to the SHU 15 traverse 14. Remove the load from the guides ropes, and they are automatically disconnected from SHU 15. The disconnected guide ropes 9 are carried out through holes in the body of the beam 14 and ZA 16 and transfer their ends to rescuers located on the SWR. Rescuers connect the ends of the guide ropes 9 with SHU 12 KSV. The SPU operators set the constant tension mode of the guide ropes and lower the yoke 14 along them until the jaws 16 of the yoke 16 are automatically connected to the ШУ 12 КСВ.

Turn on the automatic tracking system for tracking the tension of the cargo ropes 8. When the SWR is lifted by a wave, the follower winches automatically select the freight ropes 8 with an effort adequate to the total mass of the load hangers 6 with the traverse 14. When the SWR moves to the sole of the wave, the ropes are etched under the influence of the mass of the SWR.

Rescuers are lifted aboard the ship 1. With hoists of the cargo ropes, 8 KSV 3 are lifted from the water to a height that excludes mutual fluctuations of the KSV with the vessel, and they press the KSV to the crane guard 2, rolling the SPU bridge 4 up to the touch of the KSV body of the crane guard 2. Mooring and towing ropes 17 tighten, preventing longitudinal movements of the SWR. The ladder is installed 18. Rescuers on the ladder go to the CWS and open the exit hatch 10. Submariners are evacuated from the CWS to the deck of the ship along the ladder 18. After the submariners go to the ship, the rescuers bring the hatch of the hatch 11 to its original position. The exit hatch 10 is closed. Rescuers go to the ship. Gangway 18 is being cleaned.

Affected submariners are provided with primary medical care. If necessary, conduct medical recompression of the crew of the pl in the decompression chambers of the vessel. Salvaged submariners are accommodated in designated areas. The SWR is lowered into the water and towed to the base using mooring and towing ropes 17.

The use of the present invention provides the evacuation of the crew from the CWS on board the rescue vessel in conditions of sea disturbance.

The invention has novelty and utility.

A new way is to ensure the rapid evacuation of vertical salvage rescued from the CWS to the rescue vessel, in which the CWS is equipped with rod devices, the exit hatch and lifted from the water with the traverse of the launching and lifting device to a height that excludes vertical fluctuations of the CWS relative to the vessel, and secured to the crane horizontal movements, which allows for the transfer of rescued from the CWS to the side of the vessel along the ladder.

The proposed method for evacuating existing and prospective submarine projects from retrofitted CWS can be implemented by rescue vessels using both onboard and aft SPU equipped with a traverse.
