Description

Complex for rescue crew of a sunken ship, lifting and towing the latter.

Intended for use in the naval, marine and river fleets, hydro construction, in marine archeology, etc.

U.S. Patent No. 1814689 of 07/14/1931 is known. An underwater rescue vessel for releasing a crew from a sunken vessel to a salvage vessel, driven by rescue buoy top-down drives, setting the rescuer at an adjustable distance of the buoy's travel along the sensor, and the divers holding the bow and stern chain fasteners with hard hooks in the eyes of the hull of the sunken ship, as well as by fastening the tension ropes of the centering direction of the input of the lower and upper hatches of the rescue buoy, at the entrance and exit of the rescued, corresponding to by opening and closing the hatches of ships and buoys, with the escape of the rescued vessel into the decompression chamber.

This technical solution saves the team at a very slow pace in time and cannot provide mobile assistance to the whole team and the vessel at the same time. In the presence of a significant side roll of landing on the ground of a sunken ship, it is difficult or impossible to dock a rescue buoy to its transition hatch, because the rescue buoy is suspended vertically and with lateral movable communication on tension ropes with centering landing in the ship’s hatches, and to ensure the buoy’s landing by loosening the ropes leads to its slipping towards the heel by displacement and depressurization of the landing joint. The patent does not solve the problem even when the vessel’s crew was cut off by completely flooding the neighboring compartment, the outlet hatch was defective and the filled pressure water could not be pumped out of the compartment to ensure an attempt to rescue the crew.

These problems are solved by the invention. The complex for rescue of the crew of the sunken ship, lifting and towing of the latter, which provides the technology for rescuing the crew by transfer to the rescue submarine and restoring the buoyancy of the ship to lifting and towing, is carried out simultaneously, immersed with a cover on top of the object, built to the sides of the submarine under pumping conditions water from under the hood with landing on the ground and the supply of atmospheric air under the hood.

The complex for rescuing a crew of a sunken ship, lifting and towing the latter, is an underwater-guided rescue and ship-lifting structure, including a submarine with hatches located below and connected to its sides with a hood for covering the sunken ship from above, connected to auxiliary vessels and communication systems, life support and supplying under the cap a foaming liquid solution for filling the compartments of the sunken ship and after sealing holes, while the cap is made with feed thieves with seals, pumps for pumping water out of the hood, upper transverse ropes to prevent collisions with the sunken ship, lower transverse ropes for winding under the sunken ship, as well as side, stern and bow trailers for securing the said transverse and tow ropes. Stern gates are made with a height equal to 2/3 the height of the hood from its base, and open up. The lower side of the cap body is made with a support edge bent outward, in which there are located nozzles for supplying water under the external protective apron fixed along the perimeter of the cap, communicated through check valves with the mentioned pumps for pumping water, to level the soil and theft of sludge. The cap is made with bow and stern tanks located at the bow and stern of the submarine for adjusting trim and with tanks of lateral stability filled with polyurethane foam along the sides of the submarine.

The cap of the complex is made with hinged ladders pivotally mounted in the lower part of its sides, which can be lowered onto a sunken ship.

A complex for rescuing a crew of a sunken ship, lifting and towing the latter in FIGS. 1-9, comprising a submarine 1 with lower hatches for transferring a crew from a sunken ship along the retractable flexible ladders 22, is made with a cap 2 located below and connected to its sides for immersed covering the wreck with autonomous actions of the rescue complex using all types of navigational and telemetry means and working together with auxiliary technological vessels B and C with the floating hospital I A, with the equipped means of lifting the drowning nets 20 and the helipad 21, with the appropriate arrangement at sea during rescue and control through communication systems K1 and K2 through a blocking regulation system 5 of the mode of supply of life support elements for lifeguards under cap 2, as well as supply under the cap 2 foaming liquid solution for filling compartments and after sealing holes of a sunken ship when restoring its buoyancy. The cap 2 of the complex is made with aft gate 10 with a height equal to 2/3 of the height from its base, upwardly opening brackets 11 and hydraulic actuators 12. Closing the gate 10 is made with sealing hydraulic actuating seals 16 in the lower part. The lower side of the cap 2 is made around the perimeter with the support edge bent outward with the pumps 6 installed, check valves 7 connected to the expanding nozzles 3 for pumping water out of the cap 2, by supplying an external anti-pressure protective apron 8 fixed above the nozzles 3, to level the soil and theft sludge, improving the fit of the apron 8 and protection against external pressure. The complex is made with located at the bow and stern of the submarine 1 bow and stern containers 5 trim trim, and placed along on top of the sides of the submarine 1, filled with polyurethane foam containers BO lateral stability. The cap 2 is made with the upper transverse ropes 13 to prevent collisions with the sunken ship, mounted on the onboard couplings of the SC, and the lower transverse ropes 14 to protect against loss of the vessel when the volume and towing under the cap are installed under the hull of the sunken vessel by vibro-towing firmware, with the eyelet secured with rope 14 under the cover of the VI vibro-tool for attaching the ends of the ropes with thimbles to the onboard trailers of the SC. The removed ropes 14 are made stored in fork pockets along the sides. To install the lower transverse ropes 14 by lifeguards down to the bottom, hood 2 is made with articulated ladders 9 with magnetic holders in the upper part at the side of the vessel and at the side of the hood with a tightening spring and magnet, a tension rope L is attached to the upper end of the ladder 9, and the other end connected to the centerline of submarine 1 with a large loop sag for capture by a lifeguard and attraction to the side of the sunken ship for launching to the bottom.

To maintain the inertial forces of the towed vessel under the hood 2, there are bow and stern tow ropes 18 and 19 with braided thimbles, which are fastened at one end on the SC side trailers, and the other ends are laid in forked sides of the sides. Technological illumination of cap 2 of submarine 1 is carried out on both sides by projection illuminators 15, and control of the transfer of the rescued crew from the sunken ship to the submarine and restoration of buoyancy for lifting and towing is made by television receivers 17. Cap 2 is also made underwater television to inspect the axial landing of the cover a sunken ship with uniform passages along the sides, as well as process pipes along the sides, supplying air, oxygen, acetylene, drinking water, liquid solution enopoliuretana, extraction of carbon dioxide and air, hot air drying for local, terminated with connecting sockets for consumers reinforcement, formed as low-voltage cable lines for a portable tool and voltages for welding. Rescuers are equipped with radiotelephones, have overalls, underwater equipment in case of emergency, as well as sets of tools and devices. In the niches of cap 2, various materials are laid out and packed for any repair work on the restoration of the vessel, as well as reserve containers of liquid polyurethane foam with connections to pipe networks and end devices for filling in the compartment, and other materials.

To speed up the rescue work, all teams are composed by type of work. To speed up the arrival of the rescue complex to the disaster site, it is made with the possibility of towing auxiliary vessels B and C.

Upon arrival in the disaster area, a sunken object is searched for using sonar and underwater television and preparations are underway for diving, checking life support communication systems from ships B and C and from hospital A. All ships and the complex occupy their anchor positions, except for the complex. The immersion of the complex for rescue of the crew of the sunken ship begins, with the transfer under cap 2 to submarine 1 when air is supplied with the searchlights 15 turned on and the telecommunications systems K1 and K2 working, underwater television and sonar system for a uniform landing, formation of passages along the sides. Not reaching the ground, the pumps 6 for pumping water from the cap 2 are turned on to maintain the suction stream of the water supply stream, giving the protective apron 8 a flat position before landing on the ground.

After landing on the ground of the complex with the edges of the bottom of the cap 2 bent outward, a decrease in the water level begins, while the supply of atmospheric air under the cap 2 begins, with some excess pressure. With the liberation of the upper structures of the sunken ship from the water, the hatches of submarine 1 open, the ladders 22 lower and the rescuers of the ship rescue team descend, who, using the Morse signs, connect with the sunken ones, open the hatches and transfer the rescued to submarine 1 for medical assistance.

Pumping water from the cap 2 is carried out until the appearance of soil on the side marks of depths on the housing 2, for safe descent to the bottom. Subsequently, the pumping pumps 6 operate in emergency safety mode of safety conditions from a possible breakthrough of external pressure water under cap 2, by rupture of the external pressure-protective apron 8.

From cap 2, water is pumped out. The assembly group descends to the bottom by applying ladders 9 with magnetic attraction to the sides of the salvage vessel, pulling the ropes L to lay lower transverse ropes 14 under the hull of the vessel from loss of the vessel when lifting and towing. The ropes 14 are pulled by fastening the end of the thimble in the body of the VI vibro-tool, applying axial forces along the rope 14 and fastening them to the onboard hooks of the SC. Then the ends of the tow ropes 18 and 19 of the hood 2 are superimposed on the bow and stern bollards of the rescue vessel.

The rescue repair team drains the water from the compartments of the vessel and, after examining the large side-bow hole, taking into account the sea depth and speed, restores the vessel's buoyancy by filling the compartments completely with polyurethane foam, for this purpose, the structural elements of the compartments of the compartments are dried with hot air, which enhances the adhesion of dry elements to the polymer, by supply via communication lines K1 to them K2 from vessels B and C through the regulatory system 5 of the mode and through the network of the hood 2 to the tips of the hoses. Then the compartments are protected against leakage of the solution during pouring by applying strong armored polymer fabric to the sides on a special glue.

And the compartments are completely filled with polyurethane foam, hardening in the air with dense waterproof protection, with the adoption of the form of compartments. The buoyancy of the ship is restored. Checking the closing of fenders, hatches, installed ropes 14 and the imposition of the towing ropes 18 and 19 on the bow and stern bollards of the rescue vessel. A command is given to leave the vessel and the rescuers fold down the stairs 9 attached to the sides, which, by inertia of the push by the attraction of springs, are applied to the clutches of the magnets at the sides of the hood 2. Rescuers enter stairs 22 into submarine 1, removing the stairs and closing the hatches. The operation of the pumps 6 and the air supply is stopped. Under cap 2, water filtered by pressed ground enters the water, the submarine regulates buoyancy pressure on the ground, the flow of water increases and the rescue ship sways afloat, and then the complex starts to slowly lift the crew to rescue the sunken ship, lift and tow by adjusting the buoyancy of submarine 1 and the lifting force of the cap, as well as the possible lower force of the salvaged ship sunk on the upper transverse ropes 13, the tension of the towing ropes 18 and 19. Moreover, the side walls filled with polyurethane foam s capacity BO transverse stability located above the submarine body 1 is adjusted complex stability from tipping.

Thus, the buoyancy of the vessel must be accurately determined taking into account the depth of the flooded place in the sea.

With the ascent of the complex, auxiliary vessels B and C are removed from the anchors, the communication systems K1 and K2 are selected by disconnection from damage when towing to the base of the refinery, and the complex is towed. In this case, the rescued crew of the vessel is transmitted by the approach of hospital A to the board of submarine 1 and the hospital delivers the complex at high speed to the base. The towed complex gets to the base of the repair plant, where it is exempted from towing vessels B and C, enters shunting operations into the airlock 23 (or floating dock), where, by regulating the descent or lifting of the dock with the landing of the complex on special supports, the rescuers are freed from the salvaged wreck by disconnecting and stacking the transverse ropes 14 in the forked pockets of the sides and laying in the niches of the cap 2 the disconnected ends of the towing ropes 18 and 19. Then, maneuvering the water level of the lock chamber or dock and floating By the complexity of the complex, the lock is abandoned by its own passage to the parking lot.

This technology has a significant advantage over the US patent and can be used in a wide range of rescue teams of ships and the scuba diving ships themselves, as well as ships of our distant ancestors with historical values and gold items, the rise of ships of the Second World War is not excluded. In addition, the complex has the influence of inspiring the morale of the fleet and the entire personnel, that in difficult situational conditions there is support and hope for help and saving a life, and it costs a lot, for this a person performs heroic feats and works wonders for the perfection of the personality spirit.
