Description

The invention relates to the field of shipbuilding and concerns the creation of means for transporting, installing, removing goods underwater, as well as for inspection, maintenance, repair of underwater structures and specialized operations, such as under-ice seismic surveys and the elimination of under-ice oil spills.

The invention is known “A method of carrying out a hoisting-and-transport operation and a submarine for its implementation” (Patent RU No. 2478517 C2 IPC: B63C 7/00; B63G 8/00), taken as an analogue intended for carrying out underwater hoisting-and-transport operations, such as delivery of the payload to a given point in the water in an underwater position and its installation at the bottom, lifting to the surface of underwater objects, including fishing equipment, lifting from the bottom and moving underwater objects under ice without surfacing, etc. The submarine consists of a two-hull submarine, in the permeable hull of which are located, a cargo compartment with lifting equipment, ship supports for installing the submarine on the ground during the lifting and transport operation, the vessel is also equipped with a ballast system, thrusters, a locking system and detachment of the transported underwater object.

The disadvantages of the known design are:

- the need to set the submarine on the ground during an underwater hoisting-and-transport operation of the underwater object, which limits the depth range of the underwater hoisting-and-transport operation to the range of the depth of the underwater vessel;

- loading / unloading to / from an underwater vessel of an underwater object is possible only from below, which requires the need for equipment of a specially equipped site for reloading underwater objects at the bottom of the water area, additional technical means to ensure transportation, removal and installation of underwater objects on a specially equipped site for reloading underwater objects and providing a minimum depth for the organization of a specially equipped site for reloading underwater objects, for loading operations Ki / unloading of underwater objects on a submarine.

Known "Cargo submarine" (GB Patent No. 8605865 DO (GB No. 2172854 A, GB No. 2172854 В) IPC: В63В 3/13 25/00) taken as an analogue, designed to perform underwater operations, in particular various types of operations associated with development of subsea oil and gas fields. The objective of the invention is to provide a device for performing underwater operations, which is quite universal, which eliminates the need to use surface ships.

The invention provides a device for conducting operations underwater in the form of a submarine having two independent strong hulls connected to each other in front by a transverse strong hull. At the rear, the sturdy housings are connected to each other by means of a suitable connection, which can be realized by either a sturdy housing or lightweight structures. Two durable housings are surrounded and connected to each other by a single external lightweight hydrodynamic body, the back connecting part can be formed as an integral part of a single external lightweight hydrodynamic body. Two sturdy cases connected together form a compartment for receiving and transporting one or more load modules, both sturdy cases being equipped with a cargo storage device. Cargo modules can have an external shape that repeats the external shape of a submarine, however, it is preferable that the space between the two hulls of the submarine can be formed by hatches (upper and lower) or similar devices included in a single external lightweight hydrodynamic hull of the submarine, thus the shape of the submarine boats can be independent of the external form of cargo modules.

The disadvantages of the known design is:

lack of own lifting equipment;

the fixed dimensions of the cargo modules, the size of which is limited by the upper and lower hatches above and below, in front by a transverse strong hull, and behind by a rear link, included in a single external hydrodynamic hull of a submarine;

the ability to load / unload transported cargo modules to / from a submarine only from above.

- creation of the design of a multi-purpose submarine for transporting, installing, removing goods underwater, with the possibility of loading and unloading small and bulky goods from above and below, as well as the possibility of carrying out horizontal loading and unloading in the above-water position;

- the possibility of loading and unloading by lifting equipment of coastal bases due to the possibility of loading and unloading small and bulky goods from above;

- the possibility of loading and unloading by ship lifting equipment due to the possibility of loading and unloading small and bulky goods from above;

- the possibility of carrying out horizontal loading and unloading of small and bulky goods with the help of technical equipment of coastal bases in the surface position;

- lack of need for equipment of a specially equipped platform for transshipment of goods at the bottom of the water area due to the possibility of loading and unloading small and bulky goods from above;

- the absence of the need for additional technical means to ensure the transportation, installation and removal of goods to a specially equipped site for transshipment of goods due to the possibility of loading and unloading small and bulky goods from above;

- reduction in the cost of lifting operations by reducing the number of involved technical means and the absence of additional facilities for loading / unloading operations;

- reduction of loading / unloading time due to the absence of intermediate operations for transshipment of goods to the bottom of the water area.
