00 Co. / The invention relates to shipbuilding, in particular to lighter carriers. A lighter colony is known, comprising a housing with a 1-barrel hold and aft end of a cathedral type that has a notch and equipped with a laznort, as well as a self-propelled feed pusher 1. The disadvantages of the known lighter carrier are small cargo capacity and a long time for carrying out loading and unloading of watercraft and displacement vessels . The purpose of the invention is to increase the cargo capacity of the lighter carrier and to reduce the time for carrying out operations for reloading watercrafts and displacement goods. The goal is achieved by the fact that a lighter carrier, comprising a hull with cargo hold and aft end of catamaran ooze, which has a notch and equipped with a lazport, as well as a self-propelled aft pusher console, is fitted between the self-propelled aft extension shell and the aft end of the hull transition spacer, made with a cutout on the side of its aft tip, located symmetrically relative to the median plane, while the width of the cutout in the aft tip of Kopriyca is catamarano The type is equal to the cargo width () 1o of the hold, and the floating transitional spacer is connected by means of detachable knots. It is attached to the aft end of the body of the lift truck and to the nasal tip of the self-propelled feed pusher; -pusher, and the contours of the transitional spacers smoothly mated with the contours of the aft end of the hull of the lighter carrier. On fi1. 1 shows a lighter carrier linked with a transitional spacer and self-propelled stern G1) and an insert with a partially removed upper deck, plan view; in fig. 2 is a view along the diametrical plane of a lighter carrier connected with a transitional spacer and a self-propelled feed adapter; in fig. 3 lighter carrier in preparation for unloading, view in plan, transitional spacer, mixed with self-propelled aft prefix after uncoupling from the stern of the lighter carrier was brought up and moored to the ship’s side, the stern lazport was closed; in fig. 4 - a lighter carrier in preparation for unloading cargo, side view, in the cargo hold of a lighter carrier received by gravity outboard water to the level of the waterline, the cargo in the hold in the water-tight state, the stern lazport is closed; in fig. 5 shows the withdrawal of a watercraft or a displacement cargo from a hold with an open stern lazport, side view; in fig. 6 shows the operation of withdrawing a watercraft or a displacement cargo from a hold with an open lance port, plan view. Likhterovoz 1 includes hull 2 with cargo hold 3 and aft tip 4 of catamaran type, in which a cutout 5 is provided in a cargo hold 3, closed with a folding lance port 6. A floating intermediate transition spacer 7 is installed between the hulls of catamaran aft tip 4 , in which a cut-out 8 is made from the side of its aft tip for a self-propelled aft pusher 9, for example, a seaworthy pusher tug. Cut 8c transition spacer 7 is located symmetrically with respect to the median plane. The aft end 4, the intermediate spacer 7 and the self-propelled feed console 9 are mated to each other with detachable attachment points — with any known semi-rigid device 10 for the coupling. In cargo hold 3, bounded by the upper deck 11 and sides 12, a floating craft or displacement load 14 is installed on the cargo deck 13. The width of the notch 5 in the aft end of the hull 2 with the cargo hold formed by the catamaran profile is equal to the width of the cargo hold 3. Bypass of the transitional spacer 7 smoothly mated with the aft of the aft end 4 of the body 2 having cargo hold 3. To unload the cargo 14 from the cargo hold 3 of the lighter carrier 1 from the self-propelled aft console 9, the device 10 is remotely attached in the intermediate spacer 7 and the aft end 4 of the catamaran type of lighter carrier 1 and using the propulsion unit of the self-propelled feed console 9, it comes out of the joint with the aft tip 4, the intermediate floating spacer 7, coupled with the self-propelled aft console 9, and faces to the side of the board 9, it is i Then the undocking of the coupling device 10 is made between the self-propelled aft prefix 9 and the intermediate spacer 7. The self-propelled attachment 9 comes out of the notch 8 of the intermediate spacer 7. One temporarily, the lighter carrier 1 gravitationally draws 3 seawater into the cargo hold to the level of the waterline. The load 14 floats above the cargo deck 13, after which the notch 5 opens freely into the cargo hold 3 by lowering the folding lacport 6. After this, the self-propelled feed set-top 9, using the towing end attached to the load 14, leads through the notch 5 from the cargo hold 3 and takes cargo 14 to the pier. The loading of displacement cargo 14 (floating craft) into the cargo hold 3 of the lighter carrier 1 is carried out in the reverse order. In the cargo hold 3 open from the stern with the folding lapelport 6 lowered and the lighter carrier 1 sunk, the vessel or displacement load 14 is afloat afloat. Liftport 6 is raised and the cutout 5 is closed in cargo hold 3, then water is pumped out of cargo hold 3 Thereby, the cargo or watercraft 14 sits on the keel-blocks or directly onto the cargo deck 13 and is secured in a traveling manner. The self-propelled feed attachment 9 enters the notch 8 of the intermediate spacer 7 and is attached to it with the splicing device 10. In the attached position, the self-propelled attachment 9 drives the intermediate spacer 7 to the normal position at the stern end 4 of the catamaran type. Then the spacer 7 is remotely attached to the hull 2 with the unlocking device 10. The lighter carrier ship 1 is prepared for the voyage. For the possibility of docking and uncoupling of the self-propelled aft console 9 with intermediate spacer 7 and the aft end 4 of the lighter carrier 1 in the range of operational sediments of the self-propelled feed console 9 and intermediate spacer 7 are equipped with a ballast system.

The proposed lighter carrier, in comparison with the known one, makes it possible to carry out the loading and transportation of floating equipment and other displacement goods in width close to the width of the hold. Since the width of the cut-out leading to the hold is equal to the width of the hold, there is no need for loading and unloading the movement of cargo afloat to the sides and from the sides to the center plane. The presence of an intermediate spacer makes it possible to cut in it any shape and design for articulation with a self-propelled feed console, and therefore the proposed vessel-lighter carrier can use a sea-going pusher for a barge-tow structure of a corresponding capacity as a self-propelled attachment. The proposed liner carrier has an increased cargo capacity and reduces the time for carrying out transshipment operations.
