deck 6, it is approached by a ramp 21 housed in hull 2. The opening in the Bow bulkhead 22 of hull 2 has a watertight closure 23. In the aft part of hull 3 between the side hulls 2 and the central hull 1 there are spaces 24 for storing float sections 25 of the two transshipment bridges 26. The floating sections are interconnected by shafts 27 and 28, and the end section 29 of the transshipment bridges is connected to the main deck 6 by means of a hinge 30.

In the underwater part of the vessel, the bow 31 and stern 32 screw-left columns are installed, which can be lifted into the engine rooms 33 and 34 located in the tips of the side hulls 1 on the main deck. The side 1 and middle 2 hulls form a single underwater hull from the nose to the transom 35, located in front of the angarami bridges 26. From the nose to the transom 35, the submarine portion of the hull (bottom) has a weakly defined trimaran shape, and behind the transom 35, the trimaran hull. Adjacent floating sections of the bridge 26 are connected by means of a transition section 37, on each side of which horizontal shafts 27 and 28 are located, with the adjacent sections of the bridge having three supporting structures 38.39 and 40, and the transition section having two supporting structures 41 and 42 the structures, in succession, form a type of gear joint in plan. At the ends of the transition section 37, beyond the transverse dimension of the bridge 26, there are on each side guiding elements 43 in the form of a parallelogram 44. The sections have 45 transverse and 46 longitudinal watertight bulkheads, and on the bridge road 47 there are lateral protruding fences 48 49 has a reduced height of the bead 50 and the exit 51 in part 52 extending towards the shore 53. On the inner edges 54 of the side 1 and middle 2 hulls from the level of the load waterline 55 to the upper position of the guide elements 43 arcuate guide 56, which move the guide members 43 via g. elektrogidrav nical P 1iiodl.

The vessel is used as follows.

In the port of departure, the vessel is loaded with the necessary cargo onto cargo decks and in the onboard cargo compartments adapted for the transport of bulk and liquid cargo. On board the ship, standard ship mechanization and self-propelled transshipment facilities are carried out to carry out unloading on an unequipped shore (auto-loaders of various types, cargo truck cranes), cargo vehicles (trucks, air-cushion platforms and amphibious weight) that can operate in various on different soils and different slopes of the coast and the coastal bottom. In the place of unloading the vessel approaches the coast for a safe distance, the operation is made of rmoy toward the shore and becomes at the bow and stern anchor, vscherzhiva distance equal to the length of the dock levellers. At the same time, the splash protection closures 13 of the stern openings 12 are lifted. After placing on the crust, the loading bridges 26 are set in working position. To do this, using an electro-hydraulic device of the left and right side guiding elements 43 of the left and right side, the stern pairs of floating sections 25 of the loading bridge 26 are moved along 56. Initially, it occupies the working position of the end coastal pair of sections 49, and then continues to lower all other pairs of floating sections into the water. The last section of the ship section is 29, which rotates around axis 30 and is set to the level of the main cargo deck 6. The left axle 26 is pre-prepared for operation. On it, amphibians nyot t gach moves to the shore. Use it if necessary, as well as using a maneuver.

The vessel’s position is finally determined by the position of the coastal section of the bridge and the bridge as a whole. The position of the vessel at the site of the crust is finally fixed. Similarly, another bridge is installed. After that, the vessel was prepared for unloading cargo onto the Neobrudino shore. Of truck space

on the main 6, intermediate 7 and upper 5 decks, ship mechanization unloads ashore along four process lines, since the width of the transshipment bridge is chosen from the conditions of ensuring as the maximum intensification of the transshipment process (double-sided or bridge), and overload reliability in conditions of roughness by controlling sufficient stability and non-closure of the bridge sections and their minimum drawdowns when the traffic is moving. From the upper 5 and intermediate 7 cargo decks, the cargo is moved to the main deck 6 by means of an elevator 17 and a ramp 21.

In the case of using the vessel as a buffer temporary floating reloading pier-bridge, cargo operations are carried out in the following order. After the final delivery of the vessel to the core, a nasal opening 14 is opened on the main deck 6. The nasal wing closure 15 opens to the sides. A cargo vessel is moored to the bow of the ship with a horizontal mode of cargo operations. The mooring scheme for this vessel depends on the type of stern or bow ramp (straight, angled or angled). With the help of mooring vessels, they are fixed between each other, and the vessel's ramp of the cargo vessel is installed on the cargo deck of the vessel with buoy bridges. After the final fixation of ships, cargo operations begin. The cargo moves along the ramp onto cargo deck 6, and then along transshipment bridge 26 - to the shore

After the completion of the cargo operations, the rash is removed, the cargo vessel departs from the vessel with reloading floating bridges. The nasal gates 15 are closed, the overload bridges 26 are removed successively. First, the ship section 29 of the bridge 26 is rotated around the axis 30, for which the supporting-guide elements 43 from the load waterline 55 to the upper position of the shaft 27 are moved along the guides 56. After the installation of the first pair of sections 25 of the bridge 26, the remaining sections of the bridge are sequentially set to the traveling position. The last section of the end section 49 is removed. The sections of the left bridge are fastened in a marching way. Another transshipping bridge 26 is similarly removed. The splashproof closures 13 are lowered into the openings 12. The nasal bulkhead 22 Housings 2 on the main deck b and the closures 18 of the wheelhouse 16 of the elevator shaft 17 are sealed with sea-going 17. The vessel is ready for operation .
