Description

It Object of the invention, a barge transport ship for transport of barges in several levels, with a closable opening in the Ship's hull, in and out of the hull by the barges be able to create, taking the hull ballast tanks has, by means of which the hull are flooded so far can the barge get into the ship and maneuver in the ship can be.

From the DT-OS 1 930 771 is a so-called lighter-mothership with a closable stern opening for introducing and deploying buoyant barges known, the lighters are conveyed in the ship by means of suitable conveying and / or lifting devices to predetermined target locations. The ship has following the aft ship opening to the interior of the ship towards a lock chamber with lock gates, in which the lighter with flooded fairway and open aft ship opening are floatable and.

It Object of the invention, such a barge mothership so to design that the bargen or lighter, as they also called be loaded much faster and with less effort can, the draft of the ship being much lower should be as in the known design. About that In addition, the ship should be designed very advantageous in such a way that it is largely a common internal structure with ribs and Schotten has, so that its structural stability clearly is improved.

The The task is solved by flooding the hull of the ship. and having accessible holds for the barges, wherein the holds on several, preferably three, loading levels are arranged. Through the creation of floodable cargo holds in the hull it is possible the barges, and in particular large barges, move easily within the hull to be able to quickly and easily get to their final place can be steered. Means of transport inside the Ship for the barges are therefore not necessary advantageous!

In Embodiment of the invention is provided that in the ship at least a lock for raising or lowering barges a predetermined loading level is present. This can be very simply lowering the vessel to load the top Loading level to the necessary depth be waived. The barge transport ship according to the invention So it can also start ports or reeds with a relatively low water level and be easily loaded or unloaded. Also the lock in the bow or stern of the vessel for retracting the barge can by use an inner lock to be kept much smaller and will thus safer against Seeschlag. Overall, this results in a simpler and easier execution of the ship.

In Embodiment of the invention is provided that the locks gates in the ship's longitudinal direction through which the barges on the respective loading level in the locks on or can extend. Thus, the loading of the ship is accelerated, as in a central arrangement of the lock in the ship only short distances for surrendering the barges in the ship. On top of that, the barges in the ship already can be steered to their final position, if a new barge has already been raised or lowered in the lock becomes.

In Another embodiment of the invention is provided that up to six holds in one loading level to a flooded and deflectable Loading unit are summarized, being between the holds a loading unit no doors are arranged.

By the summary of holds becomes load units eases the movement of the barges in the hull and flooding and Lenzen the holds can with less installation effort be effected. The holds of a load unit become according to plan flooded or steered so that a stable swimming position results, with ballast tanks support the achievement of this floating position.

In Another embodiment of the invention is provided that in the Sluices hinged carriers are arranged on which Bargen can be transported. So is the room usable in barges for barge transport.

In the holds itself is advantageously provided that Wall supports are present, preferably hydraulic or pneumatically operated wall supports, z. In pillow form, who put the barges in the holds. While standing The bar is good on its flat bottoms, yet it is with a longer sea transport and with larger ones Movements of the ship to be expected that the barges in the Load spaces wander. This is done by wall supports reliably prevented. The barges can of course be lashed in the usual way. This is however time-consuming.

In a further embodiment of the invention, it is particularly advantageously provided that in the locks hydraulic displacement body or mechanical lifting devices are arranged to accelerate the loading and unloading. So a further acceleration of the charging and discharging process is achieved.

In Advantageous embodiment of the invention is further provided, that the flooding and emptying of holds to loading and unloading Unloading of the ship takes place according to the specifications of a stowage plan, the considered the trim position of the ship. A stowage plan is a common tool for safe operation and unloading a ship, which is also beneficial here becomes.

The Barge transport ship according to the invention is intended in particular used for transport of EUROPA II barges. These are relatively large lighter with a Length of 76.6 meters and a width of 11.4 meters, usually z. B. be used on the Rhine. For such big ones Barges fall in the Rhine mouth ports Liegezeiten for loading and unloading, which are significant. By be the barge transport ship according to the invention this EUROPA II type lighter invention advantageous to components of a transport system that provides a much faster, easier goods and goods transport in connection with Inland waterways, z. B. on the Rhine, allows.

The The invention will become more apparent from the illustrations and description from the figures and explanations, as well as from the subclaims, further inventive Details can be taken.

The Optimization of the entire transport chain of an overseas transport task requires the consideration and analysis of work processes in the different sections. From the hinterland to the seaports Become goods by road, rail and waterway brought to the seaports and transhipped to seagoing vessels. In the port of arrival, the distribution of goods takes place analogously over Road, rail and waterway. In case that the transport goods or containers on the way to the shipping port and from the port of arrival to the destination of the waterway can be transported, opening up different Ways to reduce the number of transhipment operations. This requires alternative concepts to conventional container handling, but also to the transhipment of bulk goods, to develop.

to Reduction of time and costs can be achieved by inland waterway vessels (Bargen) are loaded with their cargo directly to a ship. This can be done with the help of a modern barge carrier concept realize.

In detail:

to Avoiding the large draft when loading barge carriers According to the invention, a lock is integrated in the fuselage, which advantageously allows the transport of barges to the upper decks. This opens up new possibilities, in particular in terms of loading height, so this concept From three levels of loading emanates to the efficiency of the carrier to increase.

A barge carrier with the dimensions: length 300 meters, width 54 meters, draft 8.9 meters and a capacity of 122,500 tons can carry a total of thirty-two EUROPA II barges, eight on the lower deck and twelve on the two above lying decks. ( 2 )

On The lower deck can due to the low displacement in this area of the ship in the fore and aft area no additional barges will be accommodated.

In order to In the area of the locks also barges are transported on each floor can be here, extendable or hinged Carriers are installed who can hold the barges.

For each barge an extra space is provided. So that the construction of the ship is not complicated by watertight doors between the individual holdings, eini ge cargo holds summarized. In the foreship area this applies to the holds 1 and 2 and 3, 4 and 6 on the upper deck, and for the loading spaces 11 and 12 and 13, 14 and 16 on the middle deck. In the rear of the boat the following rooms are summarized: 5, 7 and 8 as well as 10 and 9 for the upper deck. The corresponding rooms for the middle deck are 19 and 20 as well as 15, 17 and 18. These rooms should only be flooded or led together. The locks have two doors in each deck, which can be opened longitudinally to the fore and aft of the ship.

loading process:

In the first step, the lower loading level is flooded four meters high with water. In addition, the ballast tanks are filled with water so far that the water level in the ship with the sea water level is in one plane. Now the Bugtor can be opened and always two barges can be swum at the same time, like 3 shows. The holds 25 and 26 are loaded first, then the holds 23 and 24 follow.

In the second step, the first barges are driven into the lock and lifted at the level of the middle deck. ( 4 )

Around The barges have to navigate there now here too the cargo holds to be loaded four meters high Water to be filled. The doors between the Starboard lock and the cargo hold 13 and between the port lock and the loading space 18 are opened, and the spaces 15 and 16 loaded. Then the locks are emptied. It follows up the same way the loading of the rooms 14 and 17 and then rooms 13 and 18. After that the locks are emptied and with new barges for the rooms 11 and 20 loaded. For that the doors are between the starboard lock and room 19 and the doors between the Port lock and room 12 open. Subsequently takes place in the same way the loading of the rooms 12 and 19th

Partial loading of the upper deck:

The third step is almost identical to the second, except that the barges are now lifted one level higher with the lock. ( 5 )

The Asymmetrical merging of holds prevents this Emerge of an unfavorable trim position during the loading and unloading operations.

For the loading will be the corresponding holds in the upper deck four meters high or flooded a bit higher with water.

Loading the upper deck:

When all holds are filled, the last barges are lifted to the top level. ( 6 ) There the carriers are driven under the floating barges. When these are fixed, the water can be drained off again and the next loading step started.

Loaded the lock chamber on the middle deck: in the fifth loading step Now, as in step four, the last barges in the middle deck fixed on the extendable straps in the lock.

Swim in of the last barges on the lower deck: In the last loading step two barges are floated down into the lock chambers and two more into the holds 21 and 22, which until now had to be kept free as access for the lock. ( 8th ) Then the bow gate is closed and all the water is pumped out of the holds and the barges tied down or otherwise fixed. This completes the loading of the barge carrier.

to Avoidance of stability-critical loading processes it is necessary to flood only the holds in which the barges in the lock are to be stored or have to drive through.

Instead of filling the lock completely with water, the use of displacement bodies below the lighter is provided. These bodies can be either air-filled rubber cushions or steel treads that can be mechanically extended by means of a hydraulic system. The use of displacement bodies significantly accelerates the loading and unloading process and reduces the unfavorable weight distribution within the vessel through the water in the lock in the ship's center. ( 9 )

This Lock concept with at least partial use of displacement bodies allows a particularly favorable arrangement of the gates in the rear of the ship, because the holds of each loading deck in different Heights can be variably arranged. This allows a more favorable hydrodynamic design of the foredeck. Here the use of diesel-electric is recommended Drives with a machine arrangement in the fore section. In the foreship area So is the use of diesel generator sets provided, while the propellers, preferably rudder propellers, to easier maneuvering in ports where no tugs are available, are provided in the rear.
