Description

The utility model relates to shipbuilding, in particular to the hulls of marine structures for the magnetic processing of surface ships and submarines, civilian vessels, as well as vessels for conducting scientific research related to magnetic fields.

In order to reduce the probability of detection by the enemy, to reduce the deviation of the magnetic compass, or to reduce the likelihood of detonation of mines during the fighting, metal vessels and ships are subjected to demagnetization. During demagnetization, ships or vessels are exposed to an external magnetic field at stationary or mobile demagnetization stations.

A known method of demagnetization of ships, based on the electromagnetic processing of the hull in a compensated magnetic field of the Earth by means of an alternating magnetic field created by the working winding, in which the ship moves through the working winding or moving the working winding along the longitudinal axis of the vessel (patent RU No. 2583257, class B63G 9/06, H01F 13/00, publ. 05/10/2016).

This technical solution is suitable for the demagnetization of marine vessels, however, a non-mobile stationary object is proposed here, requiring a large amount of dredging and having significant restrictions on operation during operation in tidal seas. Also, the material of the mobile pontoon is not indicated.

A known system for the demagnetization of floating ferromagnetic objects, consisting of a demagnetizing stand with an annular working winding, installed onshore based on a bench rigid support, and when floating based between floating working modules (patent RU No. 2185305, class B63G 9/06, H01F 13 / 00, V63VN 25/42, published on July 20, 2002).

In the process of demagnetization by means of a cable and a winch, a floating ferromagnetic object is moved through the working winding, while the distance of movement of the object is several of its lengths.

This technical solution is suitable for the demagnetization of marine vessels, however, due to the need to forcibly move the vessel to a considerable distance, its use is laborious and requires the use of expensive equipment.

Known pontoon for monitoring magnetic and acoustic fields, made in the form of a non-self-propelled reinforced concrete or metal vessel with bottom, side, partition and deck ceilings, described in patent RU No. 101425, class. B63B 35/44, publ. January 20, 2011. Containers with technological equipment of the electromagnetic processing complex are located in the cargo compartments of the pontoon.

The disadvantages of this technical solution are:

- reinforced concrete and, moreover, the metal case contains a large number of ferromagnetic materials, which introduces distortions in the operation of magneto-processing and magneto-measuring systems;

- the impossibility of installing winding demagnetizing systems;

- the absence in the floating pontoon of compartments for receiving liquid or solid ballast, necessary to align the level of the pontoon deck with the level of the deck of the piers, as well as to compensate for possible heeling angles and trim when installing equipment;

- the difficulty of using a floating pontoon in conjunction with existing typical berths of Project 16180, 16181 and 1516-T, associated with significant difficulties due to the need to adjust the location and orientation of the connecting hinges on the floating pontoon for each standard berth.

The problem solved by the proposed utility model is the creation of a hull of a marine floating structure made of non-magnetic materials that is immune to the effects of magnetic fields and does not adversely affect magnetic fields, designed to carry magnet-processing and magneto-measuring systems.

The problem is solved due to the fact that the hull of a marine floating structure made of non-magnetic materials is structurally made in the form of a dock and is formed of flat and ribbed concrete slabs (sections) of deck ceilings, internal and external sides, bottom, longitudinal and transverse bulkheads reinforced with non-magnetic reinforcement materials forming the internal compartments, while in the floor slabs of the inner sides and decks, supporting structures are provided for the placement of magneto-forming and magneto-measuring systems.

The technical result from the use of this technical solution is to improve the technical, economic and operational characteristics of the hulls of offshore structures intended for the magnetic processing of surface ships and submarines, civilian vessels, as well as vessels for conducting scientific research related to magnetic fields.

The essence of the proposed utility model is illustrated in the figure, which shows a cross section of the hull of a marine floating structure made of non-magnetic materials in the working position, with a demagnetized vessel.

The body of a marine floating structure made of non-magnetic materials is made in the form of a dock and consists of reinforced with reinforcement made of non-magnetic materials (for example, composite polymer reinforcement - basalt-polymer, glass-polymer, carbon-polymer, reinforcement made of titanium, aluminum-magnesium alloys, reinforcement made of non-magnetic or low-magnetic steel) flat and ribbed concrete plates (sections) of deck ceilings 1, ceilings of the inner side 2, ceilings of the outer side 3, bottom floor 4. Overlapping longitudinal 5 and transverse 6 per borok divide the internal space into internal compartments 7. At the inner side slabs 2 and 1 are arranged deck slab carrying structure 8 for placing and magnitoobrazuyuschih magnitoizmeryayuschih systems (in the figure are not shown). The space between the floors of the inner sides 2 and the deck floor 1 forms the working area 9. The ship (vessel) 10 is located in the water area, ready to undergo the demagnetization procedure.

The hull of a marine floating structure made of non-magnetic materials in the form of a dock, manufactured in the factory by splicing flat and ribbed concrete slabs (sections) of floor ceilings reinforced with reinforcement from non-magnetic materials: deck 1, inner side 2, outer side 3, bottom 4, and also longitudinal longitudinal 5 and transverse bulkheads 6 with magneto-forming and magneto-measuring systems mounted on the supporting structures 8, is towed to the water area. Then it ballasts (it sinks or completely sinks to the seabed), taking 7 ballasts into the internal compartments. Then, the processed ship (vessel) 10 enters the working area 9 of the body of the marine floating structure and is fixed in it (for example, by ropes, cables). Next, magnetic processing of the ship (vessel) 10 is performed. After all operations in the working area 9, the ship (ship) 10 is withdrawn from it. The body of a marine floating structure made of non-magnetic materials, if necessary, floats up to expose the deck pontoon 1 to the deck, providing the ability to service magneto-forming and magneto-measuring systems.

The proposed design of the hull of a marine floating structure made of non-magnetic materials allows:

- reduce operating costs and increase the service life of the hull of a marine floating structure through the use of materials not subject to corrosion,

- minimize the distortions introduced into the result of the work of magneto-processing and magneto-measuring systems, due to the formation of a body of non-magnetic materials: concrete and non-magnetic reinforcement,

- to exclude underwater work when servicing demagnetizing devices and systems,

- to implement the possibility of sea haul of the hull to a new location,

- to provide the possibility of exploitation in tidal and tidal seas,

- reduce or virtually eliminate the amount of dredging in the area of installation.
