Description

The invention relates to the field of development of mineral resources of the bowels of the Arctic shelf. The level of development of the scientific and technical base in this area requires improvement, the development of new methods and means of search, exploration and mining.

The waters of the Arctic seas are areas in which for 6 months or more a year storm and ice conditions make it difficult or even impossible for surface research vessels to work.

The world practice of offshore operations does not have submarine research vessels.

In accordance with the requirements of regulatory documents, a research vessel must carry out a complex of marine surveys: engineering-geodetic, engineering-geophysical, engineering-geological, engineering-hydrographic, engineering-hydrometeorological, lithodynamic studies, environmental studies.

At the same time, when arranging and operating offshore Arctic fields, it is necessary to carry out the following applied underwater operations:

• Survey of soil, as well as underwater pipelines, cable lines and underwater structures;

• Monitoring the technical condition of underwater structures, pipelines and equipment;

• Installation and dismantling of underwater equipment;

• Repair and maintenance work on underwater structures and underwater pipelines.

Submarines performing these works are not available. Two submarines are known that could be considered as analogues for the MPS:

- Rescue diesel-electric submarine of project 940, equipped with a deep-sea diving complex to a depth of use of 300 m. However, the submarine performs only the tasks of rescuing the crews of submarines of the Navy. ("Domestic submarines. Design and construction", Central Research Institute named after Academician A.N. Krylov, S.-Pb., 2004).

- Underwater laboratory "Bentos-300" of project 1603 is intended for:

• daily monitoring of the life of fish, benthos, plankton and marine animals;

• performing continuous measurements and recording the physicochemical parameters of the marine environment, the fields of the Earth;

• records of biological noise of the sea;

• conducting research using divers.

Bentos is towed to the dive site by a surface supply vessel (Malachite - to the submarine forces of Russia, FSUE S.-P. MBM Malakhit, published by Gangut, 2006).

According to their dimensions and purpose, these submarines cannot serve as prototypes for the MPS.

The proposed multi-purpose underwater station (MPS) is capable of performing year-round the entire range of work on offshore exploration, as well as underwater technical work related to the development and operation of offshore Arctic deposits.

MPS consists of 7 compartments:

I compartment - for research equipment, a deep-sea diving complex and control posts for uninhabited underwater vehicles and underwater technological equipment. At the bottom of the compartment is a gateway for divers to exit. A self-propelled pop-up camera is installed above the first compartment to save the entire crew and hangars for the release and reception of uninhabited underwater vehicles, and a battery is located in the lower part of the compartment.

Compartment II - the central post, crew cabins, public spaces, a galley, a food chamber, an infirmary, an insulator. In the upper part of the compartment - retractable devices, devices for thawing ice, the entrance hatch. At the bottom is a battery.

III compartment - the premises of auxiliary mechanisms and life support systems.

IV compartment - the premises of a nuclear power plant.

V compartment - turbogenerator.

VI compartment - compartment of the main propeller motor.

VII compartment - compartment of auxiliary mechanisms.

In the bow structures of the light hull there is a cargo hold with a cargo device.

In the area of compartment III there is a reserve propulsion system. In the stern structures of the light hull there are two winches for seismic streamers.

The proposed MPS, due to the specific features of operation, has in its appearance a number of significant differences from previously created submarines for the Navy.

First of all, this concerns the need to place research equipment, lock devices, lifting equipment and underwater equipment at the Ministry of Railways.

Given the need to reduce the displacement and dimensions of the Ministry of Railways in order to increase its maneuverability, it is planned to install specialized underwater equipment in the form of replaceable equipment placed depending on specific flight tasks (for example, devices for erosion of the soil, an underwater bulldozer, devices for soil sampling).

The proposed vessel performs the above list of research and underwater technical work year-round in the waters, most of the time covered by ice.

The drawing shows the general location of the Ministry of Railways, where in special compartments are located: research equipment 1, a diving complex 2, lock compartments for divers and soil samples 3, as well as hangars for receiving and releasing uninhabited underwater vehicles 4.

Equipment for underwater technical work is placed in cargo hold 5: a complex for erosion of soil, a complex for repair of pipelines, an earth moving complex.

They are not accepted on board the vessel at the same time, but as necessary to carry out work scheduled for the voyage.

The vessel can also carry out 2D and 3D seismic operations, for which seismicity 6 release and receiving winches are provided in the aft end, and winches with emitters of the required acoustic power are placed in the cargo hold.

Nuclear power plant 7 provides year-round scuba diving. Replacement of nuclear fuel occurs during factory repairs. The safety of the crew provides a self-propelled pop-up camera 8, designed for the entire crew. It is equipped with means for finding the wormwood that it floats into.

In addition, the vessel is capable of icing up and has the ability to destroy ice using a device for breaking ice 9 with the aim of the crew on ice.

The proposed MGTS makes it possible to carry out a year-round set of research and underwater technical works that ensure the development of the Arctic shelf, and can be manufactured at Russian shipyards using existing technologies for creating underwater equipment for the Navy.
