Description

This invention relates to shipbuilding, in particular to composite transport vessels.

A composite transport vessel is known, containing cargo and energy sections, capable of matching and connecting with each other by means of a hitch device including locking elements, while the cargo section contains a continuous upper deck, double sides and double bottom, is located-, Q beam in the diametral plane, two consoles located along the sides in the aft part, and the energy section contains two hulls with a common upper deck, on the outer sides of which cuts are made, in shape and Dimensions is identical cantilevers m freight units 1.

However, the performance of cargo operations on such a vessel is ineffective and requires a lot of labor.

The purpose of the invention is to increase the efficiency and reduce the labor intensity of cargo operations on a composite transport vessel.

The goal is achieved by the fact that the composite transport vessel is provided with an additional console located in the center plane of the cargo section in the stern part and rigidly connected to the beam located in its center plane; the aft part of the cargo section is open throughout the cross section, the height of the onboard and additional consoles in the place of their attachment to the hull is equal to the height of the side of the cargo section, and the height of the stern tips of the said consoles is equal to 0.25 of the height of the side of the cargo section, the width of each side The cargo section console is equal to the width of its double side, and the width of the additional console is equal to the width of the beam located in its diametral plane, the energy section is made with a width and height equal to the width and height of the cargo section in its nose, in the diametral plane a cutout is made and sizes identical to the additional console of the cargo section, and the fixing elements of the coupling device are installed in the fore and aft parts of each console and are located in the horizontal plane.

FIG. 1 shows schematically a composite transport vessel, axonometrics; in fig. 2 - energy section, axonometric; in fig. 3 - composite transport vessel, plan; in fig. 4 - the same, longitudinal section; in fig. 5 - cargo section, cross section; in fig. 6 is a section of the vessel A-A in FIG. 3. Composite transport vessel includes cargo section 1 and energy section of catamaran type. 2. Cargo, section contains tank 3, nasal waterproof bulkhead 4, upper palab 5, double bottom 6, double sides 7, ballast tanks 8, volume beam 9 in the diametral plane formed by two waterproof longitudinal bulkheads 10 with ballast tanks 11, side consoles 12, console 13 and two cargo holds 14, located along the entire length of the cargo section of section 1. The ballast 8 and 11 tanks are separated by waterproof transverse bulkheads 15. The power section contains two hulls 16 connected in the upper part In one housing 17, upper deck 18, side slices 19 and a cutout 20 located in the diametral plane, a superstructure 21. In each housing 16 there is an engine room 22, and in the general housing 17 there is a room 23 for accommodating drives of sliding cylinders 24, hinged fixing elements. Consoles 12 and 13 in the bow have openings 25, and in the stern - openings 26. Position 27 denotes the load (roundwood, whips in bundles or rafts) in the hold 14 of the vessel. The vessel is used as follows. Before loading, the vessel becomes on the roadstead or in the port waters, after which the energy section is separated from the cargo section. The cargo section is ballastised to the required draft by taking water ballast into tanks 8 and 11. With the help of port tugs, bundles or cargo rafts 27 by pushing or putting them in the hold by means of a special ship device are brought into holds 14 through the open stern section Loading of cargo is performed simultaneously in both holds. After loading the holds with the first light brown of the load beams 27 and securing them, the cargo section is again ballasted so that the next load beams Russian 27 can be loaded. This operation is repeated until the holds are loaded to the upper deck. Thereafter, the energy section, which has been pre-ballasted before the cargo sediment of the aft end of the cargo section, is moored to it. Consoles 12 and 13 are included in the cutters 19 and the notch 20 of the housing of the energy section. The cylinders 24 are driven into the holes 25 and 26 of the consoles with the help of actuators and thereby fix the consoles and rigidly connect the cargo and power sections. After docking of section 1 (.s, the ballast is pumped out of the cargo and energy section tanks. The upper deck is loaded with floating or coastal cargo vehicles, if there is a Need for it. Afterwards, the vessel leaves for voyage. The sequence of unloading the vessel is performed in reverse order. Application of the proposed composite transport vessel allows to preserve the unity of the transport characteristics of timber cargo - beam or raft along the whole technological transport chain - from production to the place consumed This does not require changing the sizes and masses of the beams and rafts, disbanding them into smaller transport units (packages) and, consequently, additional material and labor costs. The intensity of ship cargo operations will increase, the carrying capacity of vessels will increase. because they are protected from direct exposure to waves, and the safety of ships will increase due to the creation of additional buoyancy at the expense of the forest in the hold. The presence of this buoyancy and the partial closure of the open stern of the cargo section with the hulls of the energy section, taking into account the attachment of rafts and bundles in the holds, excludes the possibility of their spontaneous exit from the holds during navigation. The presence of a diametric bulk beam on the cargo section increases the longitudinal rigidity of the core. The use of the energy section of the width and height of the side, equal to the width and height of the side of the cargo section, provides maximum opening of the aft open part of the cargo space of the latter. This allows loading the hold with beams and rafts of wide width and carrying out cargo operations along two production lines. A third console of the cargo section increases the strength and reliability of the coupling connection of the two parts of the composite vessel. The introduction of two groups of locking elements of the coupling device located in the fore and aft parts of the consoles increases the efficiency of the coupling device.
