Description

The invention relates to a cargo ship for the transport of motor vehicles and / or dry cargo, the motor vehicle holds, each with several permanently installed and stacked Vehicle decks and dry cargo holds accessible via ramps having, the holds are separated from one another by transverse bulkheads

A cargo ship has become known (Marine Eng, January 1955, p. 57) in which a motor vehicle hold extends over almost Vi of the length of the ship with fixed loading decks arranged one above the other. The loading with motor vehicles is carried out at the rear according to the "RolI-on / Roll-offa" principle. A cargo space in the front of the vehicle is separated from the vehicle cargo space by a transverse bulkhead and is used to accommodate other cargo, in particular packaged goods.

A cargo ship has also become known (Marine Engeneer and Naval Architect, September 1970) at the motor vehicles are picked up from the deck between the engine room and the superstructure, whereby the Loading takes place via a rear hatch

Finally, cargo ships have also become known that have motor vehicle holds that over protrude from the upper deck (see Shipbuilding and Shipping Record of June 6, 1969, pp. 769 and 770). aside from that It is known from such ships that the motor vehicle loading decks are connected to one another by ramps (see The Motorship, February 1968, p. 511).

The invention is based on the object to provide a cargo ship that is under almost complete Use of its carrying capacity can transport motor vehicles and / or dry cargo.

According to the invention, this object is achieved in that the dry cargo holds and the Motor vehicle holds are arranged one behind the other in an alternating sequence in the longitudinal direction and that one or more motor vehicle holds in a manner known per se in superstructures located above them continue above the main deck.

In the case of the cargo ship according to the invention, there is a clear separation between the motor vehicle holds and the dry cargo holds, which alternate in the longitudinal direction. Since the motor vehicle holds do not accept any other cargo, they are not soiled. A further advantage of the invention is that solid automotive cargo decks can be built and expensive construction is avoided by hoistable loading deck Due to the alternate arrangement of automotive cargo bays and dry cargo holds is lor on the ship sufficient turning space vehicles available.

With the invention, a cargo ship is created that has a low manufacturing cost, has a low weight in relation to the load-bearing capacity and a loading of motor vehicles within the shortest possible time allows Da motor vehicles normally can have a low weight in relation to the volume in the case of the cargo ship according to the invention the load capacity can be almost fully utilized even if only the dry cargo holds are loaded This is particularly the case when bulk goods with a high specific weight are picked up is, for example iron ore. Finally, the arrangement of the individual cargo holds ensures that too when picking up motor vehicles or dry cargo alone, the position of the ship is not impaired will

Since the cargo holds at the stern and bow An embodiment of the invention provides that they are not particularly suitable for accommodating motor vehicle loading decks provide that the cargo hold furthest forward and the cargo hold furthest aft, are preferably dry cargo holds that hold bulk goods.

Another advantageous embodiment of the invention is characterized in that the motor vehicle cargo spaces ^{comprise approximately 2} / a of the total cargo space. In particular, when bulk goods with a relatively high specific weight are to be transported, for example iron ore, the cargo spaces provided for this require very little space in order to reach the limit of their carrying capacity. Motor vehicles, on the other hand, require a relatively large amount of cargo space with a relatively low weight. A subdivision of the entire hold therefore requires that the motor vehicle holds take up a greater length than the dry cargo holds. In addition, when the total cargo space is divided up in this way, there is particularly favorable cargo distribution with regard to the

tend longitudinal strength problems.

Another advantageous embodiment of the invention is characterized in that the individual Motor vehicle holds are the same size and that the dry cargo holds are the same large and different from the Kraftfahrzcugladerächer in capacity. With such a The division achieves the advantage that the same components are used in each case in the manufacture of the ship can be.

An exemplary embodiment of the invention is described in more detail below with reference to the drawings will.

F j g. Fig. 1 shows in section a cargo ship according to the invention;

F i g. 2 shows a plan view of a cargo ship according to Fiel.

The in the F i g. 1 and 2 cargo ship shown has motor vehicle holds 10, 11 and 12, which in the longitudinal direction with dry cargo holdings 13,14,15 and ie alternate any cargo, in particular Bulk goods, for example ore, are supposed to take up. the Motor vehicle holds 10 to 12 are separated from the dry cargo holds 13 to 16 by transverse bulkheads 17 separated from one another The transverse bulkheads 17 are drawn upwards beyond the level of the upper deck 18. Their height, and thus that of the motor vehicle holds 10 to 12, is indicated by a line of sight 19 of the navigating bridge 20 limited

In the motor vehicle holds 10 to 12 are vertically superimposed horizontally Motor vehicle loading decks 21 arranged The motor vehicle loading decks 21 are permanently installed and through Ramps 22 interconnected. In the plan view in FIG. 2, the ramps 22 are also indicated, wherein the right-pointing down arrow and the left-pointing up arrow Indicate ramps. Further motor vehicle loading decks 23 are between the engine room 24 and the superstructure decks, which contain the living decks, the navigating bridge 20 and other facilities Through the interconnection of the Kxaft vehicle loading decks comes the navigating bridge 20 and thus the Line of sight 19 relatively high too. lie what down S to the level of the transverse bulkheads 17, with which they over the Upper deck can be pulled out, has a beneficial effect. The motor vehicle loading decks 23 are also permanently installed and connected to one another by ramps 22.

ίο In F i g. 2 it can also be seen that the transverse bulkheads 17 are provided with watertight gates 25. The gates 25 are at the level of the upper deck 13 and allow access to the individual Y- vehicle holds 10 to 12 and 23. V / ie in FIG. 2, three land ramps 26, 27 and 28 are laid out on the port side, which can be driven over motor vehicles to be loaded or unloaded. Appropriately pre-drawn lanes are provided on the ship, one of which is shown at 29, which is

ao in front of a hatch 30 above the dry cargo hold 13 forks. The other further holds 14 to 16 also have hatches 30 which can be closed by foldable hatch covers 31 known per se.
In the example shown, a

he cargo ship shows that with a length over all of 230 m can transport 4500 cars, the subdivision of the individual cargo holds is chosen so that the Dry cargo holds 13 to 16 at most 1/3 of the capacity of the motor vehicle holds 10 to 12. For example, if ore is picked up from holds 13 to 16, it is used the carrying capacity of the ship is almost 100% even if only a few or none at all Cars are transported.

One shown in FIG. The crane 32 shown in FIG. 1 is used only for loading provisions, machine parts or the like for loading or unloading the holds 10 to 16 is not provided. The loading of motor vehicles takes place via the land ramps.
