DE3036242A1 - Extended capacity float-in-float-off ship - has bulk cargo silos above holds to empty into lighters - Google Patents

Abstract

The silos (3) are fitted above the holds with removable hatches at the top (1) and bottom (2) so that the bulk loads can be dropped down onto lighters in the hold. This extends the carrying capacity of the ship, especially for inland waterways. The holds have end doors to float the lighters in and out, with the water level adjusted by ballast tanks in the ship. The loaded lighters are replaced by empty ones and the bulk load is discharged in measured quantities. For use in heavy seas the top heavy silos remain empty as required.

Description

State of the art

The attached Fig. A (technical status) shows the state of the art shown.

Transport ships of the float-in-float-off type with one or more Docking basins and loading decks for accommodating watercraft in one In their docking basins, they can accommodate so many vessels in a shielding manner, how to find space there.

Additional cargo in the form of general cargo, large parts, etc. for use the carrying capacity of the transport ship can either be on the closed hatch covers the watercraft itself or be stowed on the upper deck of the transport ship. (e.g. BACOLINER from TNSW) If the upper deck of the transport ship is not included or to open, the ship can optionally also carry non-buoyant cargo in the Damming the docking basin.

if suitable ramp facilities are available, the ship can optionally also pick up rolling cargo. (e.g. Condock type from Nobiskrug shipyard) are known also transport ships for watercraft, which these in a flooded dock area swim in and stow in several layers on top of each other and transport non-swimming can.

Both ships are known to carry the barges within the Dock space free vertical movement, due to non-fixed support structures, let, (e.g. DT PS 2214177 C 3) as well as ships, which for every position of swimming barges, which can be recorded, at least one associated swim-in opening in different Furthermore, a lighter transport ship is known that on several superimposed loading decks can accommodate watercraft, which in a Lockable lock chamber connected to the loading decks through an opening floated in from the outside and filled with water to the level of the individual loading deck can be lifted and after opening the connection from the lock chamber to the relevant dock to be flooded onto the deck previously flooded with water can.

Deficiencies in the state of the art Transport ships of the float-in-float-off type only so many watercraft can be loaded with watercraft in one location Record at once as space is available on the loading decks.

However, additional bulk cargo can only be carried if conventional cargo holds are available for this. Should this additional bulk cargo can also be stowed on watercraft at the destination of a transport trip without that lifting and handling facilities on land must be used the ship's facilities must be available to carry out this transfer.

This envelope is time-consuming and takes several times as long as the process of swimming in and out of the watercraft in the docking basin.

Transport ships of the float-in-float-off type for accommodating watercraft in several superimposed layers must be dependent on loading or unloading on the number of layers several times in a row due to flooding and draining of ballast tanks and cargo space are placed in a floating state, which is an inward or outward swim which makes watercraft in and out of the ship's hold possible. The whole process loading and unloading the ship is complicated and considerably more time-consuming than a ship that only transports watercraft in one position.

Invention task The invention task was to create a transport ship of the float-in-float-off type, avoiding those described above Disadvantages of previously known types of ships is able to, in addition to watercraft also to transport bulk goods, and that this bulk goods at the destination can be loaded in or onto watercraft for further transport without time-consuming Transshipment operations carried out with onshore or ship-owned hoists for bulk cargo Need to become.

Advantageous solution to the problem of the invention The invention a new special type of ship created by a lighter transport ship from Float-in-float-off type thanks to additional equipment with above the docking basin arranged silos for bulk goods becomes a lighter transport and loading ship. Advantageously, the overseas transport of the barges is superfluous, for which bulk goods can be carried in the silos.

It is characteristic of the invention that in the upper deck of the ship above the ship structure delimiting the docking basin one or more Silos 3 for receiving and dispensing bulk goods can be integrated. These silos are provided at the top with removable covers 1 and they are on their underside closed or opened with the help of movable shut-off devices, 2, Fig. 1.

One way of loading the ship is to load it with cargo Watercraft (barges, barges, inland vessels, etc.) through closable openings to be taken floating in at least one water-filled docking basin and transported dry.

There are so many full watercraft in the ship that how to find space in the docking basin. Then the silos of the transport ship filled with the bulk cargo that is to be delivered to barges at the destination.

Another loading option arises in the event that the Lighter loads should also be loaded with bulk goods in the docking basin: In In this case, lighter that floated in empty at one end of the journey and were transported to the loading location, with the covers open 4 and at the same time open barriers 5 in the docking basin are loaded with bulk material ii, by transferring it from one loading system through the silo to the next Upper side of open or opened barges is thrown. Fig. 2.

This makes it superfluous to submerge the ship on Docktiefganj, the empty watercraft filled for loading and then filled or

to swim back in already filled barges.

This arrangement still enables the covers 6 to be open and closed barriers 7 the filling of the silos with further bulk material 12, Fig. 3. By this additional charge acceptance, the amount of on the ship storage capacity increases significantly beyond the amount that can be carried by the Barges can be included.

This arrangement still enables the covers to be closed 8 and opened barriers 9 the discharge of the bulk material located in the silos 12 by sliding it out downwards. Fiq. 4 Description of an example below the invention in its mode of action with reference to the in the attached Fig. 5-9 illustrated embodiment described without the invention on this Embodiment restrict.

The unloading process of the lighter transport and loading ship from Float-in-float-off type is advantageously done in the following way: The ship reaches its destination with loaded barges and with silos filled with bulk material, Fig. 5.

By flooding ballast tanks 13 and the docking basin 14 with Water the ship is lowered to a draft at which the water craft swim freely and the water level outside corresponds to that in the dock area, Fig. 6.

After opening the dock lock, the watercraft can swimming into the open air.

Without changing the floating position of the ship, there are now empty ones at the top open watercraft swam into the dock area and below the silo barriers positioned, Fig. 7.

If the lower silo barriers 10 are now released, it slips the bulk goods carried in the silos and fills the floating watercraft, Fig This filling process is ended at the latest by closing the silo shut-offs, when the watercraft have absorbed the maximum amount they can carry to be allowed to.

The watercraft loaded in this way are removed from the dock area swam out of the ship; empty watercraft can now be taken over again of cargo swam into the dock area of the ship in the manner described will.

This priority can be repeated until the load is completely discharged from the silos.

The draft of the ship is recorded during cargo delivery of water ballast in further ballast tanks so that the watercraft do not touch the loading deck with their bottoms.

After the cargo has been completely discharged from the silos, in the ship's dock basin once again swam empty watercraft into it.

As soon as the dock room is closed to the outside, the water becomes Out of the dachshunds, the watercraft settle on the loading deck suf and are transported back to a loading port with 'Fio'. 9.

With the above-described loading space arrangement for bulk goods in light transport ships from the float-in-float-off-Tyn as well as with the above described method of cargo transport as well as the loading of floating Watercraft is on the one hand the amount of cargo carried on a voyage of the ship can be carried, significantly increased without reducing the number of in the ship watercraft to be carried needs to be increased, on the other hand, the number fast and uncomplicated with Rordmittcln loaded watercraft, the per ship trip is available in the port of destination or at the destination after the ship has been unloaded, is essential raised.
