The presence of a reserve ABK increases the power-to-weight ratio and autonomy of the AHCS.

Diving and rescue compartment 3 is made in the form of a sphere, which ensures uniform distribution of power loads on its structure, which increases safety and allows to exclude stiffeners from the design and increase the payload of the VSGA. Compartment 3 is located in the central part of the hull and is connected from the side of the bow to the control compartment 2, from the bottom side - to the suction chamber 7 and from the aft side - to the energy compartment 4. Seats 13 are installed in it to accommodate divers and rescued divers, sealed the lower transitional hatch 14 with a lid associated with the suction chamber 7 and the upper transitional hatch 15 with a lid associated with the superstructure VSGA, life support and decompression by the method of continuous ventilation, and means of a subscriber command post 16.

It also houses the main ABK 21 with an input-output device, which houses the main lithium-ion batteries,

Equalizing tanks 26 are located in the inter-board space 25. At the same time, a removable remote-controlled uninhabited underwater vehicle (TYPE) 29 is placed in the inter-board space 25 of the bow. VSGA. TYPA allows you to independently conduct search, guidance and remote survey of emergency underwater vehicles and objects, which increases autonomy and safety during diving and rescue operations. At the same time, the removable ROV provides the possibility of its installation and removal, depending on the type of work and the need for replacement or repair. Also in the inter-board space 29 of the bow there is a radio communication unit. It is installed on deck 5 and is arranged with a winch 31, a pop-up buoy 32 and a cable-cable 33. Buoy 32 is equipped with a transmit-receive antenna and is connected to the equipment of the control compartment 2 VSGA by a cable-cable 33, which allows maintaining a two-way digital communication channel with the carrier vessel. The radio buoy provides sufficient data transfer rate and improved communication quality with the control center of the surface/submarine carrier vessel

The fixation device on the ground is located in the inter-board space 29 of the lower part of the VSGA. It is made in the form of retractable support posts 35 pivotally mounted on the foundation 34 of the solid body 1. The support posts 35 are arranged in pairs side by side. They can be installed, at least in the amount of four. Each support column 35 contains a hydraulic cylinder and, at the end, pivotally connected to it, a support platform 36, which is necessary to increase the support area. The support pads 36 are connected to the support posts 35 through hinges to avoid skew on uneven ground. The support legs 35 are removed upwards and released downwards, turning in a vertical plane by means of hydraulic cylinders with crank mechanisms. Cleaning of the support legs 35 is necessary to avoid obstructing the performance of tripping operations VSGA. The ground fixation device allows the AHSA to perform diving and underwater rescue operations while on the ground with the DRC turned off, which reduces the energy consumption of the AHSA.

Life support facilities are located in the control compartment 2 and in the diving and rescue compartment 3. The life support equipment contains absorption equipment, air collectors 37 and gas environment control equipment located in the control compartment 2 and in the diving and rescue compartment 3. The life support facilities also include means ventilation, pressurization and pressure control 38 in the compartments, air cylinders 28. Absorption equipment is used to clean the atmosphere of AHCS from harmful impurities and carbon dioxide exhaled by a person. It includes absorption units 39 and emergency rescue equipment 40 equipped with absorption cartridges.

Absorption plants 39 are located in the control compartment 2 and the diving and rescue compartment 3. In the diving and rescue compartment 3 there are also absorption plants 39 operating at elevated pressure. Emergency rescue equipment 40 with absorbing cartridges are located in the control compartment 2 and in the diving and rescue compartment 3. Absorption cartridges of emergency rescue equipment are designed for 20 rescued and 3 crew members for 72 hours. When this life support contains placed in the diving compartment 3 breathing mask 41 and air collectors 37. The air collectors 37 are made of stainless steel. Each manifold is equipped with 23 breathing mask connection points and is connected to absorption equipment. Life support equipment, by maintaining ventilation, the necessary pressure and providing air purification in the compartments, improves the quality of life support and safety of the crew and those being rescued in the AHCA.

The inventive diving and rescue deep-sea vehicle operates as follows. After immersion in water, the VSGA, using instrumentation, navigation equipment, SUD and TS, GAS equipment, independently searches and aims at the desired underwater object. In order to examine the underwater object in detail, eliminating the risk of divers, instead of them, the TYPE, which is part of the AHCA, is used. TYPA, equipped with a video camera and a manipulator, has small dimensions and is able to penetrate into various small openings and rooms of the underwater object being examined. By means of a cable-rope, TYPA transmits visual information about its location and actions performed by means of a manipulator device to the VSGA.

If the underwater object is an emergency submarine, a submarine (submarine), including lying on the ground, rescue and evacuation of submariners from it can be carried out as a "dry" method, including from compartments under high pressure, and "wet" way with the help of divers. If it is impossible to dock to the coaming platform of the emergency submarine using the suction chamber, the VSGA releases support legs by means of a fixation device on the ground, and is installed on the ground against the current with the creation of negative buoyancy. By changing the forces on the support legs, the VSGA is aligned with the roll and trim and turns off the DRC. Turning off the DRC makes it possible to significantly reduce energy costs. To establish high-quality communication with the command post of the carrier vessel, a pop-up buoy with an antenna is produced by means of a winch on a cable cable. At the same time, in the diving and rescue compartment with control of the parameters of the respiratory gas mixture from the control compartment, the necessary pressure corresponding to the depth of work is set. After setting the required pressure in the diving and rescue compartment, the divers open the cover of the lower transfer hatch and, using a descent and recovery device to descend into the water, exit the AHCS.

Further, divers carry out the required underwater technical work using hydraulic tools, means of underwater welding, metal cutting, or diving and rescue operations, including the delivery and transfer, if necessary, to an emergency facility of life-supporting and rescue equipment, or work to remove rescued divers from emergency submarine at VSGA. When carrying out underwater work, communication and video monitoring are constantly carried out with the transfer of video and audio information from the work site to the AHCS. In turn, information on the progress of underwater technical or diving and rescue operations is transmitted from the AHCS control compartment to the command post of the carrier vessel by means of a buoy of the radio communication unit.

When rescuing divers from an emergency submarine by the "wet" method with the help of divers, to speed up the process, a mechanized operation is used to raise the rescued divers from the aquatic environment on the platform of the launching device by operating the winch into the diving and rescue compartment of the VSGA. At the same time, in case of gas pollution in the diving and rescue compartment and the control compartment of the AHSA, the gas environment of the compartment is cleaned by means of the absorption equipment of life support means, ensuring the breathing of the rescued submariners, divers and crew with air without harmful impurities, which improves the quality of life support of the AHSA.

Upon completion of work and the rise of all rescued submariners and divers into the diving and rescue compartment, the cover of its lower passage hatch is closed. VSGA carries out lifting from the ground, cleaning the support legs of the device for fixing on the ground and ascent. After lifting the AHCS onto the carrier vessel, decompression is performed by means of the AHCS.

Thus, the proposed AHCS allows to improve the quality of life support, autonomy and safety with the possibility of independent search, guidance, remote inspection of an underwater object, as well as to provide mechanization, reduce energy costs, improve the quality of communication with the control center of the carrier vessel when performing diving and rescue operations without involving means of the carrier vessel.

The claimed technical solution VSGA can be used in shipbuilding and production of equipment in the manufacture of rescue deep-sea facilities.
