SUBSTANCE: invention relates to ship navigation. Proposed method of piloting ships in channels and shallow inland waters consists in using auxiliary engineering means. Said auxiliary means represents pontoons. Said pontoons represent bow and stern buoyancy modules. Underkeel clearance is increased by reducing wave resistance in running in shallow waters due to absorption of waves reflected from the hull. Waves are killed by aforesaid buoyancy modules.

The invention relates to the field of navigation and can be used to improve the safety of water transport operation when navigating through the channels and shallow areas of inland waterways.

Pilotage of ships in the shallow parts of rivers, under conditions of limited depth on inland waterways by using salvaging or special pontoons capacity 40-129 tons (Ergolding, Vphotos, Fponase. Technical diving and salvaging rescue work. - M.: Transport. - 1990, s-194). Operations on vessel on the pontoons differ in complexity and difficulty in setting the ship on the pontoons and running trim. The use of pontoons, large capacity increases the fuselage mid-section.

In addition, the ongoing vessel must be accompanied by a diving boat with a crew of divers and swimming tool compressor equipment for purging the pontoons.

The objective of the proposed technical solution is to reduce the complexity of wiring the vessel through the channels and shallow areas of inland waterways.

The problem is solved due to the fact that the way of the posting of the vessel through the channels and shallow areas of inland waterways through auxiliary means for extending the depth under the ship you anenih in the form of pontoons, unlike the prototype, the stock increased depth under the vessel is carried out by reducing wave resistance when the vessel is in shallow water due to the absorption of reflected body waves through bow and stern buoyancy module, and a device for ship routing through channels and shallow areas of inland waterways, including pontoons with fasteners to the hull, unlike the prototype, the pontoons are bow and stern buoyancy module is made in the form of a design corresponding to the configurations of the fore and aft parts of the hull, and the means of attachment to the hull is made in the form of lugs-clamps with jacks and cables for wrapping module buoyancy to the vessel.

The invention is illustrated by drawings (Fig.1-3).

Figure 1. The design of the bow buoyancy module. Bow buoyancy module is a hollow buoyant, made in the form of construction, the appropriate configuration of the bow. Bow buoyancy module includes a contoured casing 1, the end clamps 2, provided with jacks, the cable 3 for wrapping module buoyancy, flow part 4.

Figure 2. The design of the aft buoyancy module. The aft buoyancy module is a hollow buoyant, made in the form of design, with testwuide configuration aft of the vessel. The aft buoyancy module includes a contoured casing 5, the end tabs 6, equipped with jacks, cable 7 for wrapping module buoyancy, flow part 8.

Figure 3. The scheme of installation of the buoyancy modules on the ship. For the transaction of the vessel 9 through the channels and shallow areas on a set of the bow 10, the buoyancy module and feed 11 module buoyancy, buoyancy compartments - 12.

The method is implemented as follows.

For the transaction of the vessel 9 through the channels and shallow areas of inland waterways on a set of the bow 10, the buoyancy module and feed 11 module buoyancy. Moreover, the configuration of the bow 10 and feed 11 modules buoyancy same configuration, respectively, the configurations of the bow and stern configurations of the vessel 9.

The bow 10 and feed 11 buoyancy modules attached to the hull by means of stops-clamps with jacks, and cable for wrapping buoyancy module.

The bow 10 and feed 11 the buoyancy modules are hollow pontoons with balancing capability and secure them to the hull 9 taking into account the shape of the vessel 9.

The end clamps 2 and 6 by means of jacks (hydraulic or screw) to allow secure fixation of the modules buoyancy at the bow and stern end of the vessel 9 any configuration. The end clamps 2 and 6 Budwig who are after institution and decoration, accordingly cables 3 and 7. As the cables 3 and 7 you can also use the tow mate.

The flowing parts 4 and 8 are designed to ensure the manageability of the vessel 9.

The capacity of the bow 10 and feed 11 modules buoyancy depends on the length of buoyancy and is determined depending on vessel type, construction and characteristics.

The bow 10 module significantly reduces wave resistance of a ship in shallow water as the vessel 9 takes the shape of the type "vessel-iron". The configuration of the nose 10 of the buoyancy module provides absorption reflected from the hull 5 of the peculiarities of the internal surfaces to keep them in the environment. Due to this effect decreases the wave resistance.

Positive technical result of the proposed technical solution is that when using it significantly reduces wave resistance of a ship in shallow water, the buoyancy modules do not increase as the pontoons large capacity fuselage mid-section of the vessel which is essential for the movement through the channels. However, even a relatively short buoyancy modules allow you to increase the stock of depth under the vessel at 0.5 m in Addition, the buoyancy modules much easier than the pontoons are joined conducted to the vessel and do not require maintenance of diving the brigade and swimming facilities with compressor equipment for purging the pontoons.

The use of buoyancy modules, tailored to the specific vessel, will greatly improve the efficiency of fleet utilization (capacity) limited depths, significant variations of water level in the canals and waterways.

The buoyancy modules can be designed in two or three sizes that will provide the wiring dry cargo vessels series "Baltic" (projects 16290, 16291, 613), "Komarno", "Ladoga" (projects 787, 289, 285), "Volga" (project 19610), "Cupid" (project 92-040), "Volgo-Balt" (project 2-95/A), "Siberian" (project 225), "Omsk" (project 1743.1), "Sormovskiy" (614 projects, A/M3, And/M4), "STK" (project 326.1), "ST" (project 19620), "the white sea" (project 1000), Nevsky (project P-32), "Pasha", "Oyat (project 201), "Sheksna" (TA-82).
