Abstract

The invention relates to mooring devices and can be used for transshipment of large-size, tons of cargo from transport ships to the shore. The purpose of the invention is to accelerate overload and reduce operating costs. The complex contains a pontoon 1 with a superstructure 2 and movable beams 4, having the possibility of putting them on a vessel 11 equipped with supporting pillows 13. The pontoon is connected to the shore by two bridge ladders 5 moving along the mooring front. Pontoon 1 with superstructure 2 and transport vessel 11 are made with height measurements that ensure compliance with the following conditions: H 1≥H 2 max and H 3≤H 2 min, where H 1 is the elevation of the gutter surface on the superstructure of the pontoon above its waterline

H 2 max - height of the freeboard of the unloaded vessel is empty

H 2 min - the height of the ship's surface in the load

H 3 - height of the freeboard of the pontoon. 2 Il.

The invention relates to mooring devices and can be used for transshipment of large-sized tons of cargo from ships to the shore.

The purpose of the invention is to accelerate overload and reduce operating costs.

1 shows a schematic of a transshipment complex, a top view; figure 2 is the same, side view.

The transshipment complex includes a pontoon 1, to the deck of which in the middle part of it is attached an attachment 2. On the mooring side, to the pontoon 1 are attached shock absorbers 3, made of rubber pipes or other elastic materials. On the pontoon 1 there are two mobile beams 4.

The pontoon is connected to the shore by two bridge trusses 5, having stops 6 at their ends, made in the form of rods thickened downwards. The stops 6 are inserted into the channels 7, attached to the superstructure 2 and the coastal foundation 8, made of prefabricated blocks.

On the coastal platform adjacent to the foundation 8, lags 9 were laid. At both ends of the pontoon 1, ropes 10 were brought to the shore and stretched.

The pontoon 1 with the superstructure 2 and the transport vessel 11 are made with height measurements ensuring that the following conditions are met

where N. is the elevation of the surface of the chute located on the superstructure of the pontoon above its waterline;

H2 is the height of the freeboard of the vessel;

H s - the height of the freeboard of the pontoon.

The braced pontoon 1 does not have the ability to move horizontally, but freely moves vertically when the water level fluctuates in the water area. At different water levels, the trusses 5 are installed with a different slope. In Figure 2, the position of the pier is shown in solid lines with a mini

Minimal, stroke - at the maximum water level.

The connection of the pontoon 1 with the shore for the service personnel is carried out with the help of a boat or a light floating walkway.

The transshipment operations at the berth are as follows.

A transport vessel 11 is moored to pontoon 1 with a bulky cargo 12 located on support cushions 13 mounted on bars 14. The bulk of the vessel on the pontoon 1 cm is dampened by shock absorbers attached to it 3.

Under the action of mooring loads, lugs 6 attached to trusses 5 abut against grooves 7. The provided thickenings at the ends of lugs 6 prevent them from slipping out of grooves 7.

After mooring the vessel 11 of the farm 5 by moving them along the grooves 7, they are installed opposite the bars 14, the distance between which depends on the length of the cargo 12.

Beams 4 are installed adjacent to trusses 5 and are mounted on vessel 11 under support cushions 13, next to bars 14. When the height H and H are equal, beams 4 are installed horizontally, as shown in figure 2 by dashed lines, and in all other cases they are inclined, while the side of the pontoon 1 and the side of the vessel 11 do not impede the free support of the beams 4 on the deck of the vessel 11, which allows for reloading work without ballasting the pontoon 1.

To prevent longitudinal displacements of the beams 4, stop rods are inserted into the gutters 7, passing through the holes provided in the beams.

Lagi 9 is set with adjoining them to farms 5.

The required movements of beams 4, trusses 5 and lag 9 are carried out with the aid of portable winches and jacks.

The cargo 12 is attached to the tower and, together with the support cushions 1j, is moved from the vessel 11 along the beams 4, trusses 5 and lags 9 to the rear of the berth, after which the beams 4 are diverted to the pontoon 1 and the vessel 11 departs from the pier.

Upon completion of the unloading of all ships, the berth is dismantled, trusses 5, precast foundation blocks 8, lags 9, and other berth accessories are placed on pontoon 1, which is transported by water to new overloading sites.

By performing pontoon 1 with superstructure 2 and observing the above-mentioned altitude conditions, the need for ballasting the pontoon is eliminated, which simplifies its manufacture, does not require energy consumption for its ballasting and speeds up the process of reloading (by eliminating the ballasting time) by 1.5 - 2 times.
