The floating mooring transshipment device for ships with large cargo modules includes two parallel and interconnected in the same ends of the sealed wall of 1 pontoon 2, as well as a lifting body mounted on these pontoons. The device comprises a pump unit 3, a platform 4 with a rail section 5 and a synchrolift 6, a double bottom 7 and supports 8 with mechanisms 9 for their vertical movement. The pontoons 2 are equipped with rails 10 and a waterproof gate 11 mating with both ends "a" of the other extremities of the same pontoon 2 of the same name. The sealed wall of the pontoons 1 is made with a flap 12, the lifting body is made as a group of carts 13, and the double bottom 7 is fixed to the lower parts "b" of the pontoons 2, forming together with the hermetic wall 1, the gate 11 and the side walls "c" of the pontoons 2 a lock chamber 14 communicated with the pumping unit 3. The bridge 4 is connected to the extremities "g" of the pontoons 2 associated with the hermetic wall 1, and its rail section 5 is connected to the rails of 10 pontoons installed in the upper part of the latter. The supports 8 are mounted on both sides at the bottom of the “b” pontoons and trestles 4 and are kinematically connected with the mechanisms 9 of their vertical movement. Synchronizer 6 is mounted in the area of the rail section 5 overpass. Syncrolift 6 contains counterweights 15 connected to hydraulic brakes 16. Synchrolift 6 is located on the overpass 4 at a distance from

airlock, allowing a convenient location on an air cushion platforms 17, transporting cargo modules 18. The design of the synchrolift 6 may be different. The synchrolift guides 19 are designed to roll up the load-carrying trolleys 13 with cargo modules, are vertically displaceable and connected by cables or chains to counterweights 15 that can be displaced along vertical guides 20. The counterweight 15 is a metal tank, which, when installing a floating mooring device in the working position is filled with water. The weight of the counterweight 15 when filled with water exceeds the weight of the load carrying empty carriage for the latter to return to the rail section 5 of the overpass under the action of gravity.

The mechanisms 9 of the vertical movement of the supports 8 are connected through an tracking system (not shown) with inclinometers. The connection of the lock chamber with the pump unit 3 and the energy compartment (associated with the pump unit) and the overpass 4 is a single rigid metal structure that provides longitudinal and transverse strength, both during its transportation and during the vessel overload process 21.

The internal parameters of the lock chamber 14 are determined by the dimensions of the ships used 21. The confined space of the pontoons 2 is divided into two volumes. The lower part of the volume is filled with water and is equal to the volume of the water-filled part of the sluice chamber. The upper volume is equal to the volume required to keep the floating mooring transshipment device afloat at a given draft and filled with a lower volume. The side walls of the pontoons 2 are equipped with blades 22 and 23 with remote control. The clinkers 22 are intended for the entry of water into the pontoons 2 from the outer side, and the clinkers 23 for the entry of water into the pontoons 2 from the side of the sluice chamber 14.

The side walls of the pontoons 2 are also equipped with klinketami 24 for draining water from the lock chamber 14. The number of the mentioned klinkets is determined depending on their diameter and on the projected performance of the floating mooring and handling device.

The overpass 4 protruding from the airlock chamber is connected by means of the supports 25 to the base plate 26 connected to the bottom of the airlock chamber, and is a rigid structure. The end part of the overpass, immediately following the synchrolift, serves for the accumulation of empty load-carrying trucks after they are released from the cargo modules 18, and is equal in length to the total width of all loads 5

existing trolleys 13. Supports 8 are designed to absorb dynamic loads in order to maintain the strictly horizontal position of the floating mooring and handling device during the overload process. The mechanisms 9 of the vertical movement of the supports 8 can be different in design and in power they are selected so that they dampen the moments that create the roll of the device. They can have a remote control and connect to the machine that controls the roll of the device. Cargo pontoon 27 is used to transport cargo modules on it to the pier. Cabin 28 serves to control the mooring and overloading device and is mounted in its upper part, depending on the length of the floating mooring and reloading device and the power of the mechanisms.

Floating mooring-handling device can be made both self-propelled and dumb (towed).

Installation of floating mooring-handling device at the shoreline as follows. The device approaches the shore ahead of an overpass 4. Pontoons 2 are dry (Fig. 2, position I). Clinkers 22 are opened, and water flows by gravity into the pontoons 2, filling their lower volume. The device is immersed to a working draft allowing entry into the lock chamber 14 of the vessel 21 (FIG. 2, position II). After that, the device as close as possible to the shore until the moment when the nose of the bottom does not rest on the ground. Supports 8 are lowered (fig. 2, position III). As soon as the device is in place, the mechanisms 9 of the vertical movement of the supports 8 will automatically turn on from the inclinometer. Supports 8 also provide traction with the ground and protect the device from tipping over. The counterbalance tanks 15 of the synchrolift 6 are filled with water. After that, the device is ready for handling vessels 21.

Unloading the vessel is as follows.

The vessel 21 with cargo modules 18 enters the lock chamber 14. Gate 11 and the shutter 12 are closed, ensuring the water tightness of the lock chamber. The load-carrying trolleys 13 are located above the cargo modules 18 (Fig. 4). The airlock chamber 14 is filled with water from the lower compartments of the pontoons 2. The vessel 21 rises to the grippers of the load carrying carts 13. The load modules 18 engage with the load-carrying carts 13 (Fig. 5).

Water from the airlock is then removed. The vessel 21 is lowered, freeing itself from the cargo modules 18 (Fig. 6). The water level in the lock chamber 14 is compared with the water level in the sea. The gates 11 of the airlock chamber 14 are opened, and the vessel 21 throws it. The flap 12 opens and the load-carrying trolleys 13 with cargo modules 18 move along the rail section 5 of the overpass to the synchrolift 6. As soon as the load-carrying trolley 13 completely rolls onto the synchrolift guides 19, it is lowered by gravity and the cargo module 18 is mounted on the platform 17 on the air a cushion pre-installed under the synchrolift 6, which delivers it to the shore (Fig. 7). The empty load carrying trolley 13 rises syncrolift 6 for. the counterweight account 15 and moves to the zone of accumulation of empty trucks (Fig. 8).

Works floating mooring-handling device as follows.

In the working position, the pontoons 2 are partially filled with water. The load-carrying trolleys 13 are located above the lock chamber 14. The clinkers 24 for draining water from the lock chamber and the clinkers 22, 23 for filling the pontoons 2 are closed (Fig. 9). A vessel 21 is loaded into the chamber with cargo modules 18. The gate 11 and the shutter 12 of the lock chamber are closed (Fig. 10). Water from the pontoons 2 is pumped into pumps in a lock chamber 14. As the water level rises, the vessel 21 rises to the load-carrying carriages 13 until they pick up the cargo modules 18 (Fig. 11).

Then the clinkers 24 open and the water runs down from the lock chamber 14 beyond its limits in a volume equal to the weight of the cargo modules 18 (Fig. 12). The remaining volume of water, before leveling it in the lock chamber 14 with an external one, is lowered into the pontoons 2, the vessel 21 is removed (Fig. 13). As the device is released from the cargo modules .18, the pontoons 2 are filled with water through the blades 22 (Fig. 14).

The floating mooring and reloading device can be installed on an unequipped shore (see Fig. 15). Delivery of cargo modules 18 to the coast is carried out by platforms 17 on an air cushion.

When installing a floating mooring transshipment device at the port berth, under the synchrolift 6, a cargo pontoon 27 is installed. The transfer of cargo modules 18 from the synchrolift 6 to the equipped shore is carried out on wheeled vehicle platforms. Cargo pontoon 27 to ensure rigidity filled with water (Fig. 17).

Means of moving cargo modules 18 to the shore can be delivered to the place of transshipment both on auxiliary vessels and by the floating mooring-unloading device.
