Description

The invention relates to the field of rescuing crews of emergency submarines (submarines) lying on the ground, "dry" (without direct contact of the rescued submariners with the surrounding aquatic environment) and "wet" method.

For the practical implementation of the rescue of crews of emergency submarines (submarines) lying on the ground, surface and underwater carriers of technical means are used. An example of a surface carrier is the project 05275 submarine rescue vessel EPRON, which has a rescue bell and a deep-sea diving complex (GVK) with a diving bell [1]. The disadvantages of a rescue bell installed on a surface carrier are a strong dependence on adverse hydrometeorological conditions, the technical complexity of providing rescue at great depths due to an increase in the length of the cables and air hoses connecting the rescue bell with the carrier vessel, the difficulty of keeping the carrier vessel above the work site , the impossibility of providing rescue in ice conditions and under ice. GVK has a diving bell limited in volume and is not capable of carrying out a mass rescue by a "wet" method. These shortcomings were partially eliminated by replacing the rescue bell with an autonomous rescue deep-sea vehicle with its placement on an underwater carrier - a rescue submarine (SPL), as well as by placing the GVK without a diving bell, replaced by a receiving and locking device. An example is the Project 940 diesel-electric rescue submarine Lenok.

The project 940 rescue submarine had a two-hull design with a stem bow, optimizing the contours for a predominantly surface course. Behind the fence of a strong felling there was a high banquet with places for placing two rescue deep-sea vehicles (SGA) and protecting them from sea waves. Inside the strong hull of the SPL there was a GVK designed to ensure the work of deep-sea divers, rescue divers by the “wet” method and decompress the rescued divers if they were under high pressure inside the compartments of the emergency submarine [2]. SPL project 940 is taken as a prototype. The disadvantages of the prototype are the placement of SGA outside in the upper part of the submarine. The limited energy reserve on the SGA and their technical complexity, which negatively affects reliability, required the placement of two SGAs, which led to an increase in the displacement of the submarine and a decrease in its operational characteristics, including speed and stability on the surface. The technical complexity of landing the SGA on the SPL was noted. In the conditions of the Arctic, the possibilities of rescuing submariners with the help of the SPL-carrier of the SGA were limited. The diesel-electric power plant did not allow the submarine to go under the ice. The SGA also could not work under the ice, since in the event of an accident of technical means and the inability to return to the submarine, they could not surface.

The objective of the invention is to eliminate the noted shortcomings and to ensure the practical implementation of the rescue of submariners from an emergency submarine lying on the ground in Arctic conditions.

The proposed technical solution is illustrated by a graphical diagram shown in Fig., which shows a rescue submarine (SPL) designed to rescue submariners from compartments of an emergency submarine lying on the ground in a “dry” way. SPL has an outer hull 1 and a durable hull 2, and the shape of the outer hull is focused on providing a high speed of underwater travel, and a power plant that allows it to stay submerged for a long time without floating to the surface. On the SPL, in contrast to the SPL of project 940, instead of two SGAs, a rescue bell 3 is provided. missing on the prototype. For maneuvering in the work area and positioning over the emergency submarine, jointly used thrusters 4 (bow and stern), anchor device 5 (two bow and two stern anchors), underwater lighting (lanterns) 9 and surveillance 8 are installed on the SPL. wet" method and their decompression, if the divers during the rescue were in the compartments of the emergency submarine under increased pressure, as in the prototype, it is provided by the presence of a GVK with a receiving-output device and a barocomplex 7.

The advantage of the claimed SPL compared to the prototype are:

- the possibility of rescuing submariners from an emergency submarine lying on the ground under the ice;

- increased autonomous, seaworthy and driving performance due to the use of a power plant, a hull shape oriented to high underwater speed, a decrease in displacement and stability due to the replacement of the SGA with a rescue bell located in the lower part of the hull;

- the ability to navigate and maneuver underwater, as well as to hold securely above the work site due to the presence of underwater lighting and surveillance equipment operating in the complex, thrusters and an advanced anchoring device with an increased number of bottom anchors (from two to four);

- the presence of a rescue bell, which, unlike the SGA, does not depend on the capacity of the SPA batteries, allows multiple use to rescue divers, is more reliable, as it is simple in design and application technology;

The implementation of the invention will ensure the rescue of submariners who are in the compartments of an emergency submarine lying on the ground under the ice, which is currently not feasible, but is relevant.
