Description

CARRIER SHIP WITH FLUTE LOADERAUM

Description :

The invention relates to a carrier ship with at least one cargo space, which is bounded laterally by two extending in the longitudinal direction of the carrier ship walls.

It is known to load large cargo ships with containers. The loading and unloading of these large cargo ships is very time consuming and requires considerable logistics at the ports. During loading and unloading the cargo ships are not productive in use. Another problem is that some ports can not be reached by the large cargo ships because the ports are not deep enough. Another problem is that large cargo ships are common

must be reloaded to unload certain containers at intermediate ports.

From DE 1 900 871 AI it is known on a ship a

Provide receiving chamber which extends above and below the waterline. The chamber can be opened by part of the

Outside wall of the ship is extended, so accordingly a

Container floating in the receiving chamber can be introduced. Subsequently, the container is transported by crane to the ship relocated and supplied to the designated loading space. The

Recording chamber is not as a cargo space, especially not for

Transport of containers, provided.

From DE 198 45 669 AI it is known to execute ships in several parts, the individual parts can swim themselves. The individual parts can be assembled into a large ship and transported together with this large ship. For this purpose, it is necessary that all parts are accurately connected with each other. This structure is therefore relatively inflexible.

The object of the present invention is to provide a ship which can be easily and flexibly loaded and unloaded and which can be modularly constructed.

This object is achieved according to the invention by a carrier ship with at least one cargo space, which is laterally delimited by two extending in the longitudinal direction of the carrier ship walls, wherein the cargo space extends substantially over the entire length of the carrier ship and is flooded, so that cargo in the hold floating transported is and at least one of the longitudinal walls at least almost completely or at least in several sections is apparent, so that cargo is einschwimmbar side into the flooded cargo space.

The invention thus provides that not only a chamber, d. H. a small part of the carrier ship is constantly flooded, but that the entire hold is constantly flooded. The cargo space extends substantially over the entire length of the carrier ship. This means that the cargo space over more than 50%, preferably over

extends at least 80% of the length of the carrier ship. Because of that Freight floating self-storing in the hold, the carrier ship may have a shallow draft. The loading of the

Loading space can be extremely flexible, if almost the entire longitudinal wall, such as an outer wall, is apparent. Thus, parcels, z. As containers, unlike in the prior art, are floated at any point of the hold. In this case, a predominant part of the extending along the cargo space

Longitudinal wall, in particular more than 50% of the length of the longitudinal wall to be apparent. Even if the longitudinal wall in several sections is apparent, containers can be placed in different places in the hold. It is not necessary to recycle the containers within the hold. Thus, the cargo space can be discharged extremely flexible, which in turn saves time and costs. For example, the longitudinal wall can be opened in sections of 50 or 100 m. The longitudinal wall can be opened mechanically and / or hydraulically. Each parking position in the hold can be occupied as required and each piece of freight can drive on the carrier ship without hindrance.

Due to the flooding of the cargo holds the water pressure on the

Cargo space. Only the longitudinal walls with a relatively small width of about 2 - 4 m must defy the water pressure both from the inside and from the outside. To withstand this pressure, it can be provided that ship plates are installed as struts in the longitudinal walls. Preferably, the apparent longitudinal wall or at least a portion thereof may be pivotable about an axis extending in the longitudinal direction of the carrier ship. Thus, the longitudinal wall can be completely submerged at least in part, in particular, the longitudinal wall

be folded down completely or in parts like a trap door, so that cargo can be swung sideways. Special advantages arise when parallel to the cargo space

Passage channel is provided, wherein the longitudinal wall between the cargo space and the passageway is clear. Thus, cargo can be floated in the passageway. Subsequently, a longitudinal wall can be opened, so that the cargo can be swung laterally into the hold. The passageway allows containers to be moved to different positions in the hold. Although the width of the carrier ship is increased by the provision of a passageway, the cross section of the underwater vessel only becomes slightly larger, since the passageway can remain open during the journey. In particular, the

Passage channel at the bow and stern remain open. The lateral attachment of the passageway serves as protection against heavy seas.

A particularly large amount of freight can be transported if two holds are provided, which extend on both sides of the passageway. Thus, both load compartments can be loaded via the passageway. The holds need not be symmetrical. A hold may also be wider and / or deeper than the other.

When dimensioning the passageway, it should be noted that enough space is planned to allow a large proportion of the water to flow to the

passing freight can pass. An exactly fitting freight would otherwise have almost all the water on the

push out the opposite side of the channel to get ahead. In addition, the cargo, which can be designed as a ship, sufficient freedom of movement, especially when entering and leaving the hold. A wider or deeper passageway costs only marginally more fuel or material. According to an advantageous embodiment of the invention can be provided that the passage channel has liftable bulkheads.

In particular, liftable bulkheads may be provided at the two ends of the passageway. As a result, emergency braking can be triggered because the driving resistance almost doubles. For example, the last meters, for example the last 20 m of the channel floor, can be folded up. Hinged bulkheads could also prevent the entry of unwanted ships.

In the passageway, a water cleaning skimmer can be provided. Through a skimmer in the passageway, large amounts of contaminated surface water from major roads can be cleaned. The water displacement of the bow of the hold of the channel side brings about 50% higher flow velocity in the channel.

This also increases the cleaning area by 50%.

The water cleaning skimmer can be mounted extendable in the passageway. In order to be able to absorb the dirt absorbed in the dirt, a disposal unit, for example a container, can be provided at the end of the loading space.

In particular, if only a loading space and a passageway are provided, it may be advantageous if an asymmetrical bow is provided. This would make it easier to drive straight ahead with the carrier ship. In particular, a twist in the one direction, in particular in the direction of the side on which the passageway is located, can be prevented.

Special advantages arise when the hold is open at the top.

As a result, there is no limit to the height of the load. The Displacement of water or the underwater cross section of the carrier ship can be kept at the lowest level. In addition, empty and full containers can be loaded mixed. The empty containers

swim by several meters and therefore rise more in the air.

In a further embodiment of the invention, at least one motor nacelle which can be arranged on the hull, which has at least two longitudinal walls and a bottom wall, can be provided. This results in a modular design. The engine nacelle can only later on the

Hull be attached. The engine nacelles can dip as little as possible into the water to the cross section of the

Underwater hull as small as possible. The motor gondolas can be attached laterally. However, they can also be attached to the rear of the cargo hold. Fuel tanks can with the

Motor gondola be carried. This has the advantage that they can be changed quickly. Empty tanks can be floated up. This has the advantage that no ballast water is needed. No cleaning on board is necessary. Furthermore, a fast fueling, control and cleaning of the tanks during refilling in the port or at a service station is possible. A separate tank container, which can be double-walled, can almost eliminate contamination and leakage. When price or law changes, it is possible to perform a fuel metabolism without on board

cumbersome to clean or rebuild tanks. The use of motor gondolas also has the advantage that they can subsequently swim in and be mounted after the construction of the carrier ship. It is conceivable that the engine nacelle as a complete

Engine house with propeller and steering gear as finished rear of the cargo space is simply attached and mounted. There is still room for smaller ships or containers above the shaft system. Should that Carriers are scrapped, the motor gondolas can also be swum out and used elsewhere.

Preferably, two motor gondolas are used. Thus, even with maintenance or failure of a nacelle, the carrier ship can still be moved with the other engine nacelle.

As already mentioned, at least one tank container can be provided, which can be fastened to the bow of the carrier ship or a motor nacelle. Such tank containers are easier exchangeable and replaceable. Different tank containers may be provided, for example those for heavy oil and those for diesel fuel.

It is particularly advantageous if at least one Voith cutter drive is provided. With such a drive, the thrust in size and direction can be set arbitrarily, without changing the speed. Steering is done by adjusting the pitch for the front-to-back direction, and by adjusting it to the ship (rudder). This type of control gives the carrier ship maximum maneuverability and allows a very fine metering of the thrust and extremely fast change of the thrust direction without changing the

Rotation speed . If the carrier ship is equipped with two or more Voith-Schneider drives, the ship can move in any direction, including sideways.

Further advantages arise when a loading bridge is provided. Such a loading bridge may have a crane. This makes it possible to reload containers while driving. In this context, it is advantageous if at least one

Longitudinal wall is dimensioned so that containers can be stored. This makes the overall system very flexible. In particular, because of the flow channel, it is thereby also possible to load and unload the carrier ship even at slow speeds. This can prevent that the carrier ship is stopped unnecessarily often or has to be restarted from scratch. This can reduce operating costs.

It is particularly advantageous if at least one longitudinal wall,

in particular an outer wall, double-walled. This allows the longitudinal walls to function as buoyancy, ballast and

To meet storage space to match the inside depth of the hold to the draft of the loaded cargo and possibly serve as a cargo space for containers, etc.

At least one longitudinal wall may have a lateral additional, lying above the water buoyancy body as a multipurpose cultivation. This serves as additional security in the event of an accident. An extension arm can support and stabilize the lateral attachment. Container extension cranes can also be mounted on this attachment. Loren can transport longitudinally between the "legs" of the cranes

make.

Preferably, the ship's bottom is double-walled, so that it has a slight buoyancy. The ship's bottom should be

swim if the carrier ship breaks up. The same applies to the ship's walls, except for the part of the ship's walls that are apparent. In the carrier ship according to the invention, the stability of the hull is ensured by the flooded holds. With closed bulkheads of the bottom and side walls, even a breakup of the hull does not result in the loss of the carrier ship due to the already flooded holds. In any case, the cargo consists of buoyant cargo, especially ships, and is therefore not affected by it. This results in low construction costs and a simple structure. Furthermore, only low operating costs arise. The carrier ship can be operated by few staff. Of the

Energy consumption is low in relation to the charge. In particular, the operating times can be increased. The carrier ship can be loaded outside the usual ports. In particular, it is conceivable that the carrier ship is loaded and unloaded even at slow speeds. Since the cross section of the underwater hull can be kept relatively small, relatively cheap and small engines can be used. Since the holds are filled with water, the carrier ship is almost unsinkable. The risk of an oil spill is almost zero. This results in a

Premium savings at the insurance companies. For the utilization can

Carrier ship also load smaller ships or freighters. Transfer times at port terminals can be reduced. Furthermore, the carrier ship is very easy to repair. Heavy oil powered carrier ships no longer need to call the port. This eliminates the fee for pollutants. A change of tanks or fuel type is possible without alterations due to the modular design.

Further features and advantages of the invention will become apparent from the following detailed description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The ones shown there

Features are not necessary to understand to scale and such illustrated that the features of the invention can be made clearly visible. The various features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.

In the schematic drawing embodiments of the invention are illustrated and explained in more detail in the following description.

It shows: a top view of a carrier ship with a

Crane.

In the following, the same reference numbers will be used for the same components

used. FIG. 1 shows a plan view of a carrier ship 1. The

Carrier 1 has a cargo space 2 which extends over almost the entire length of the carrier ship 1. At its front end, the carrier ship 1 and the hold 2 a bow 3. in the

Cargo space 2, which is flooded, cargo 4 can be stored floating. In order to bring the cargo 4 in certain positions in the cargo space 2, a longitudinal wall 5 of the carrier ship 1 is so

trained to cover a substantial portion of their length,

preferably in its entire length or at least partially apparent, so that pieces of cargo 4 can swim sideways from a passageway 6. In particular, it is shown on the basis of the freight item 7 that this is in the longitudinal direction of the carrier ship 1 in the

Passage channel 6 can be moved. On the basis of the freight item 8 it is shown how this can be moved from the passageway 6 into the loading space 2 or vice versa.

To drive the carrier ship 1 motor nacelles 9, 10 are provided, which are laterally attached to the carrier ship or hull. Both

Motor gondolas 9, 10 are modules that are easily replaceable. The motor nacelles 9, 10 may not have tank containers, not shown here. Furthermore, a tank container 11 may be provided in the bow 3. The freight pieces 4, 7, 8 may have their own drive. In particular, the freight pieces 4, 7, 8 themselves can be designed as ships with their own drive.

If no passageway 6 were provided, the longitudinal wall 5 would be an outer wall.

From the cross-sectional illustration according to FIG. 2 it follows that the hull of the carrier ship 1 has a bottom wall 15 as well as itself upwardly extending longitudinal walls 16, 5, 17 has. The outer longitudinal walls 16, 17 are double-walled and thus automatically floating. Also, the bottom 15 is double-walled. The longitudinal wall 5, which is between the cargo space 2 and the

Passage channel 6 extends, is not double-walled, since it must be retractable. The sinking of the longitudinal wall 5 is shown by the dashed line of the longitudinal wall 5a, 5b. In particular, the longitudinal wall 5 is pivotable about a longitudinally extending in the longitudinal direction of the carrier ship 1 axis in whole or in sections. This makes it possible to move a freight item 4, 7, 8 laterally between passageway 6 and cargo space 2.

2, the motor nacelles 9, 10 and another freight piece 12 are also seen with their own drive. Propellers 18, 19 are also indicated. In FIG. 2 it is also clear that the cargo space 2 is flooded. Furthermore, it can be seen that the

Submerge motor gondolas 9, 10 only slightly in the water. The

Waterline is designated by the reference numeral 20. The passageway 6 is open at the front and rear and therefore offers only a small

Water resistance.

The embodiment of a carrier ship 30 according to FIG. 3

differs from that of FIG. 1 in that the bow 3rd

is designed asymmetrically. This can be a preferred

Direction of travel due to the asymmetry of the carrier ship 30

be compensated. Furthermore, the carrier ship 30 has no motor nacelle arranged on the side, but rather an engine nacelle 31 arranged in the rear region of the cargo space 2. A tank container 32 is located directly in front of it. In the passageway 6 is a

Water cleaning skimmer 33. The garbage taken off from the water can be stored in land a container 34 which is disposed behind the engine nacelle 31. The water-cleaning skimmer 33 may be pivotally mounted in the passageway 6 to release the passageway 6 for loading and unloading with cargo.

4 shows a plan view of a carrier ship 40 with a

Passageway 6 and two holds 2. Here it can be seen that the freight items can have very different shapes. The

Longitudinal walls 5, which delimit the passageway 6, are apparent, so that pieces of cargo 8 can be moved laterally into and out of the holds 2. Motor gondolas 31 are provided on both sides. They each have tank containers 32 and motors 35. Behind the

Motor gondolas 31 are in turn container 34 is provided, which can be supplied by water cleaning skimmer 33 debris. The

Carrier ship 40 has on both sides nor a lateral attachment 41, 42. This lateral attachment 41 may in particular be arranged above the waterline and serve as a storage, workshop warehouse, etc.

A sectional view in the area of the motor nacelles 31 can be seen in FIG. 5. Here it can be seen that both longitudinal walls 5, the

Limit passageway 6, at least in sections are apparently by these are hinged.

Fig. 6 shows an enlarged view of the right side of FIG. 5, wherein here on the longitudinal wall 17 and the attachment 41, a crane 50th

is shown, which is movable in the longitudinal direction of the carrier ship 40 and by means of which container 51 of larger pieces of freight of the

Laderaums 2 removed and elsewhere, for example, in the lateral attachment 42 can be discontinued. The carrier ship according to the invention can also be used militarily. For example, an aircraft carrier including auxiliary ships can be transported with the carrier ship. From the carrier ship, every military ship can run out of tanks and magazines in minutes. The aircraft carrier can with electric

Performing its constantly moving kilns support the propulsion of the carrier ship and additionally reduce the fuel costs. The nearly unsinkable carrier ship also lends itself as ammunition, material,

Troop and fuel provider. Furthermore, it is conceivable that

Carrier ship to use as an aircraft carrier. For example, a runway can be built on a longitudinal wall. Since that

Carrier ship is planned with lengths of up to 1,000 m, a longitudinal wall could easily serve as a runway. The

Longitudinal wall could be formed double-storey, below the

Runway and above the runway could be. At the runway only the nose wheel must be guided (in the middle).
