(54) COMPOSITE TRANSPORT SHIP

one

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

A composite transport vessel is known, comprising a cargo section and an energy section, which is made in the form of a semi-cat-tamaran containing side semi-hulls interconnected by a common stern and upper deck, with both sections being coupled devices 1.

However, the well-known vessel has limited operational capabilities.

The purpose of the invention is to extend the operational capabilities of the composite transport vessel.

 The goal is achieved by the fact that projections are made along the sides of the nose section of the cargo section, the rear wall of which is located at an acute angle to the main plane, the rear end of the cargo section is made in the form of a transom located at the same angle to the main plane, and the coupling device contains two groups of coupling elements, each of which includes recesses and cy-. linders made with the possibility of extending and mating with indentations, while the width of the onboard lopes of the cargo section is equal to the width of the semi-bodies of the energy section of the nasal tip of each semi-body and the front wall of the aft part of the energy section are at an equal acute angle to the main plane, the conjunction of cargo and energy the sections are made along inclined surfaces 10 respectively of the rear wall of the flanges and the transom of the cargo section on the nasal extremities of the semi-bodies and the front th wall energy aft section, for which the angles of inclination of said surfaces are made equal, and the bottom energy aft section formed with a rise from the sides to the center plane and from bow to stern. ,

In addition, the length of the semi-bodies of the energy section is 0.85-0.95 the length of the cargo section of the cargo section.

At the same time, one of the groups of coupling elements is located in the bow of the vessel and mounted along the sides of the cargo section with

the possibility of extending the cylinders in the vertical plane, while another group is located in the stern of the vessel and mounted in the diametral plane of the energy section with the possibility of extending the cylinders in the horizontal plane.

FIG. 1 shows schematically a composite transport vessel in axonometric view; in fig. 2 - the same in terms of; in fig. 3 - the same, longitudinal section; in fig. 4- section A-A in FIG. 2; in fig. 5 is a section BB in FIG. 2

The composite vessel contains a cargo section 1 and an energy section 2 of semi-tamaran type.

The nosal part 3 of the cargo section 1 has in the horizontal plane from each side protrusions 4, which in the vertical plane have an inclined surface 5 between the upper deck 6 and the bottom 7.

In the aft end, cargo section 1 has, between the upper deck 6 and the bottom 7, an inclined transom stern 9 over the entire width of the cargo section.

The cargo part 10 of the cargo section 1 is made in the form of a parallelepiped with vertical sides 11, double bottom 12, transverse bulkheads 13, cargo hatches 14 and hatch covers 15.

The energy section 2 consists of two side semi-hulls 16 having an outer 17 and an inner 18 side and an inclined bow-tip-forshchtevye 19, aft 20, connected to the side semi-hulls 16, upper deck 21, residential superstructure 22, aft ramp 23. Front wall 24 the aft part 20 is inclined, and the last, with a rise 25 in the bottom part in the region of the center plane of the vessel, increasing from bow to stern.

Onboard semi-hulls 16 have a double bottom, an inner deck 26 and deep tanks 27. In the aft 20 there is an engine room 28, from which two manholes 29 are placed, above which are two chimneys 30. In the bow of the energy section 2 before the superstructure 22 on the upper deck 21, rooms 31 are located for stirring the drives of the nose hitch device 32, consisting of sliding cylinders 33, bearing cavities 34, located in the deck structures 35 of the cargo section 10 of the cargo section 1. In the aft section of the energy section 2 Position the aft coupling 36.

The vessel is used as follows.

Before entering the voyage, the upper deck 21 of the energy section is loaded by means of the port in a vertical or horizontal way via the aft ramp 23. In the onboard compartments-diptanki 27, liquid cargo is taken in the form of fuel.

oils, various chemical goods, drinking water, etc. At the same time or in advance, the cargo section is loaded at another pier. After loading both sections, they are docked.

5 The docking of the cargo and energy section of the vessel is performed as follows. On the raid by means of the port to. The energy section 2 is supplied with the cargo section 1. Before the beginning of the docking of the sections, depending on the load and draft of the cargo section, the energy section is ballastised so that the sediments of the cargo and energy sections in the nose and the Kogme become correspondingly the same. Then the cargo section is stern

5 energy. After contacting the transom stern 9 of the cargo section 1 with the front wall of the aft part 20 using the stern coupling device 36, both sections are connected. After fixing and securing the aft end 8 of the cargo section, the nose section of the cargo section is secured with the help of the nose hitch 32. For this purpose, the hitch drive located in the room 31 of the energy section 2 ,. A cylinder 33 is extended, which enters and is secured in the supporting recess 34 of the structure 35 of the cargo section 10 of the cargo section 1. After docking and securing both sections, the composite vessel is ready for launch. The undocking of the sections is performed in reverse order, as is the unloading of the cargo and energy sections.

The energy section can be operated together with the cargo section as well as autonomously.

When co-sailing two sections

 a monolithic vessel is formed with coordinated fore and aft contours of the cargo and energy sections, which ensures satisfactory running, seaworthy, ice and strength properties.

Q The bow and stern coupling devices provide a reliable rigid connection between the two sections. Vertical movement of sections is limited due to their connection in the bow and stern on inclined surfaces. 5 During autonomous navigation, the energy section is operated as a normal sea self-propelled cargo ship, having normal running and seaworthy qualities. This is achieved by creating a streamlined nasal contour and inclined forts of each hull and a system of stern contours in the area of the engine room by tilting the front wall of the hull and raising the bottom of the hull in the center plane above the main line with a gradual increase in the stern. Such a shape of the feed lines ensures an improvement in the flow around the hull without breaking the jets and a uniform flow of water to the screw disk. Other qualities (total and local strength, torsion strength of the hull) of the energy section are provided by an upper deck bridge connecting the two side hulls along the entire length of the area of the cargo section and the aft hull.

The use of a two-piece koHCTpyKUHH tolucatamarana of the energy section will allow for a better fit between the load and the buoyancy of the vessel, which is especially required when transporting relatively light cargo. Such a constructive scheme of a semi-catfish boat makes it possible to easily receive any draft of a ship with a relatively small intake of ballast water, unlike a single-hull vessel of the same width with a catamaran or helix.

The cargo section of the proposed design, with the exception of the bow, reduces the cost of construction and operation. The simplicity of the hull shape makes it possible to unify it. With a uniform unified form and housing arrangements, cargo sections for various purposes can be created. Modifications of the cargo section can be designed to transport bulk, bulk, timber, piece and other cargoes and be used as temporary buffer tanks (floating warehouses).

The versatility of the proposed composite vessel expands its operational capabilities and provides the best technical and economic indicators in comparison with the well-known single-hull vessels. Efficiency is achieved by reducing the number of vessels, intensive use of the energy section, unifying the cargo section hulls, cheaper construction, saving materials, reducing operating costs and the number of equipment for the entire transportation system of the proposed transport compound vessel .:
