Description

The invention relates to a method for placing decks on superstructures of ships, in particular for retrofitting additional decks.

If additional decks are to be placed on existing superstructures of ships already in service in the course of a conversion, this has previously been done by erecting walls and ceilings that were welded onto the existing superstructures. Then this shell with windows, Insulation, installations, equipment and furniture. In order that the existing superstructures could bear the additional loads, equipment, insulation, furniture, etc. in the upper superstructures had to be dismantled and cleared out so that reinforcements could be installed within the existing decks because of the additional loads and the additional decks could be welded on. The dismantled equipment etc. not only became unusable as a result and had to be replaced later, but the heat caused by welding also caused additional damage that had to be repaired. This means a relatively high amount of work and materials, with the workload having an unfavorable weight, since this is largely incurred during the docking period of the ship to be converted, which means unproductive laytime for the shipowner.

In addition, it is known that prefabricated deckhouses that are dimensionally stable and torsionally rigid are largely completely prefabricated on land, placed on existing ship superstructures and fastened to them. These are larger units, which usually form a complete deck and, due to the relatively imprecise contact areas on the deck, have to be provided with considerable allowances at the side boundaries, which are then made to size on board to neighboring structures or the like. must be adapted by cutting off (Shipbuilding & Marine Engineering International magazine, October 1980, P. 397; Magazine "Schiff & Hafen / Kommandobrücke", issue 7/1985, p. 7 and magazine "Shipcare & Maritime Management", July / August 1985, p. 18 and 19).

In addition, from DE-OS 35 17 862 a catamaran watercraft is known which has two floating bodies which are arranged at a distance from one another and which are connected to one another by a plurality of walkable, stable cross truss girders. The longitudinal spaces between the cross truss girders are of equal length, so that unit containers which are prefabricated can be fitted between them. However, this type of construction is in no way comparable to the placement of decks on existing superstructures of ships.

The present invention has for its object to provide a method with which the time on board the ship for the equipment, in particular for conversion, and the effort for the production of the decks is significantly reduced. In addition, the facilities required to carry out the method should also be proposed.

• a) Herstellung einer Mehrzahl von komplett montierten, in sich noch nicht verwindungssteifen Deckshausmodulen mit Boden ohne Zugabemaße an Land, einschließlich dem größten Teil der Installationen und Einrichtungen;
• b) Befestigen, insbesondere Aufschweißen, von Trägern zur Bildung einer ebenen, stabilen Aufstandsfläche und zur Lastverteilung auf der Außenseite des vorhandenen Aufbaus des Schiffes über im wesentlichen die gesamte Länge und Breite des vorgesehenen Decks;
• c) Aufsetzen der Deckshausmodule auf die Träger des Aufbaus und Befestigen, insbesondere durch Verschweißen, an diesen; und
• d) Verbinden, insbesondere Verschweißen, nebeneinander stehender Deckshausmodule untereinander.

According to the present invention, this object is achieved by a method which is characterized by the following steps:

• a) Manufacture of a plurality of completely assembled, not yet torsionally rigid Deckhouse modules with no land allowance on land, including most of the installations and facilities;
• b) fastening, in particular welding, of beams to form a flat, stable contact surface and for load distribution on the outside of the existing superstructure of the ship over substantially the entire length and width of the intended deck;
• c) placing the deckhouse modules on the supports of the structure and fastening, in particular by welding, to them; and
• d) joining, in particular welding, of deck house modules standing next to one another.

Such a solution has the significant advantage that completely equipped deckhouse modules can be produced on land without side additions before the ship's arrival for the purpose of conversion, which considerably reduces the ship's berth time. By fastening, in particular welding, of beams for load distribution on the outside of the existing structure, practically no reinforcements are required within the existing structure, so that their equipment does not have to be dismantled or cleared out. Since the surfaces of the beams form a defined, exactly flat contact area, the deckhouse modules can be placed on the prepared beams and fasten easily in a short time. Only then do the welded deckhouses get their torsion-resistant shape.

The shipyard lay time can also be shortened even further by attaching the carriers to the superstructures of the ship before they enter the shipyard. This can be done either during the lay time in other ports or even while traveling by mobile personnel. A particularly advantageous embodiment of the method according to the invention is characterized in that two beams arranged in the longitudinal direction of the row are fastened to the existing structure for each row of deckhouse modules to be arranged next to one another, of which the ship-internal beam on the structure and the ship-external beam on the side wall of the structure is attached outside. These two brackets are sufficient to securely hold and attach the attached deckhouse modules. Due to the special position of the beams, the welding points to be attached are easily accessible.

In such a process, the load on both the existing structures and the attached deckhouse modules is very low due to the heat occurring during welding. The deckhouse modules can therefore be prepared and fastened in a substantially completely equipped state, and after the deckhouse modules have been fastened to the Beams and after connecting to each other, these can be completed with remaining partition and ceiling elements, etc., which means only a very small amount of time, since everything can be prepared. Preferably still open inner areas of the deckhouse modules are separated from the work areas by provisional partition walls and removed again after the corresponding work has been carried out, so that there is no fear of damage or contamination of the interior.

Since the deckhouse modules are relatively large, flat units, which are only supported in their shape after being placed on the beams for load distribution, the completely assembled but not torsionally rigid deckhouse modules are transported and opened using a special crossbar the ship lifted. The special traverse is designed as a stable frame and engages so many eyes on the deckhouse module that it can practically not deform.

The invention also relates to corresponding devices for performing the method according to the invention. A suitable deckhouse module for mounting on superstructures of ships according to the method according to the invention is characterized in that, as a preassembled frame construction with several chambers, it already has a floor, front wall with windows, rear wall and ceiling, and essentially complete equipment with chamber partitions, Has chamber ceilings, installations, insulation and interior fittings, but that there are no side end walls of the frame construction, except for end modules, and that the open ends of the frame construction are prepared without welding in the area of the floor, the front wall, the rear wall and the ceiling for welding to adjacent deckhouse modules are. With such a construction, the welding work to be carried out after placing the deckhouse modules next to one another is reduced to a minimum, since no side walls have to be welded in or connected to adjacent deckhouse modules. Such deckhouse modules have such a stability due to the frame construction from the floor, front wall, rear wall and ceiling, with suitable support structures being provided, that they can be transported and set down by means of the already mentioned special traverse without being significantly deformed. To hang it on the special traverse, the deckhouse modules are expediently provided at structurally and statically suitable locations with load eyes for attaching to the special traverse, so that the (not yet torsionally rigid) deckhouse cannot deform during transport and setting down.

So that the adjacent interior of the deckhouse modules is not damaged when welding adjacent deckhouse modules on the floor, front wall, rear wall and ceiling, the chamber dividing walls are arranged at a distance from the open ends of the frame construction, so that space for working, in particular for welding remains. After completion of this connection work, in particular welding work, these locations can then also be provided with interior fittings, for example by hanging in the remaining ceiling elements, rolling out carpets and moving furniture. Any fixed installations, such as bathrooms, are preferably not provided in this area. To achieve the same cabin lengths, the deckhouse modules are preferably designed such that a chamber partition is arranged at a distance in the region of one open end of the frame construction, while at the other end this chamber partition is missing and is formed by the corresponding chamber partition of the adjacent module. The same deckhouse modules can thus be placed next to each other and connected, and in the area of each interface there is a corresponding chamber partition wall, shifted by the distance mentioned.

Since the deckhouse modules are not provided with structural side walls, but only chamber partitions are available, special precautions must be taken with regard to fire protection. For this purpose, special deckhouse module designs are provided, which have a fire bulkhead between two adjacent chambers in the central area. The appropriate spacing between the fire bulkheads can be designed by appropriately combining "normal" deckhouse modules with such special deckhouse modules with fire bulkhead.

In order to achieve a uniform appearance of the attached decks, the posts of the deckhouse modules between the windows of the chambers in the area of the open ends of the frame construction, i.e. at the interfaces, are about half as wide as the posts in the middle area. Two such half posts are then joined together during welding and give the appearance of a post of normal width. Only the mullion between the windows of the chambers in the area of the fire bulkhead of the special deckhouse module is about 1 1/2 times as wide as in the other middle areas.

In order not to have to extend the module length of such a special deckhouse module with fire bulkhead too much compared to a normal module with the same chamber lengths, the chamber walls in the area of the open ends of the frame construction are expediently omitted in such a module and are without by the corresponding chamber partition walls of adjacent modules Fire bulkhead formed.

In order to be able to easily attach the deckhouse modules to the supports attached to the existing superstructure, the rear wall of the deckhouse modules is preferably extended and reinforced in relation to the lower edge of the floor and prepared for welding onto the ship-internal carrier of the existing superstructure, while the underside of the floor in Area of the ship's outer support is provided with a longitudinal bracket for welding onto the ship's outer support designed as a box girder. This construction ensures that the welds are accessible when the deckhouse module is attached. The attachment of a longitudinal console on the underside of the bottom of the deckhouse module is suitable for absorbing considerable forces, which arise in particular from the fact that the deckhouse module may have a large overhang over the ship's outer support. The support on the ship's interior of the existing superstructure only has to absorb smaller loads.

The deckhouse modules can be of one-story or multi-story, in particular two-story, design. The transport and installation of such deckhouse modules using the specified special crossmember ensures that even larger modules are not deformed.

Finally, the structure of the special traverse used to transport and set up the deckhouse modules should be specified. It is characterized by a stable frame for hanging in a lifting device, on which a plurality of load eyes are arranged in a predetermined grid in accordance with the deckhouse modules to be attached. This makes it possible to hang the load eyes at the points at which the deckhouse modules are stiffened by appropriate supports and can absorb the corresponding loads. The special crossbeam on the load eyes is preferably equipped with clamping screws that engage the load eyes of the deckhouse modules. By tightening and Loosening the tensioning screws can distribute the loads on the load eyes very evenly.

Further advantageous embodiments can be found in further subclaims.

The invention is explained in more detail below on the basis of several exemplary embodiments with reference to the accompanying drawings.

1 shows a section of an existing superstructure 1 of a ship, of which a deck surface 5 and a side wall 4 (with a window) can be seen. A beam 2 for load distribution is welded onto the deck surface 5 in the longitudinal direction of the ship, in the form of a T-beam. On the upper edge of the side wall 4, a further beam 3 is welded for load distribution, and this forms a box beam with the side wall 4. The beams 2 and 3 should form a completely flat contact surface and evenly distribute the load on the existing structure 1, so that it is not necessary to provide additional stiffeners in the interior of the existing structure. This would only be possible after dismantling and clearing the upper cabins. The beams 2 and 3 can be welded onto the outside of the existing structure 1 with relatively little heat so that the cabins of the existing structure 1, e.g. Wall and ceiling coverings, practically not be affected.

A deckhouse module 10, of which only the left part is shown, is placed on this partially illustrated structure 1. The deckhouse module 10 consists of a frame construction open at the ends with a front wall 12 including windows 12d, a floor 13, a ceiling 14 and a rear wall 15. This frame construction is stiffened by appropriate support formation. The deckhouse module 10 is provided in the extension of the rear wall 15 with a reinforcement 16, and in the front In the area of the deckhouse module 10 there is a longitudinal console 17. The deckhouse module 10 is placed with this reinforcement 16 and the console 17 on the supports 2 and 3, and all forces are absorbed by these parts.

2 now shows details in an enlarged representation of the fastening areas between the beams 2 and 3 and the reinforcement 16 and the bracket 17 of the deckhouse module 10, some areas having been broken out for reasons of illustration. It can be seen that the carrier 2 is welded onto the deck surface 5 of the existing structure 1 and is additionally supported in the transverse position by thrust knees. The carrier 2 is expediently arranged on the deck surface 5 where there are longitudinal members (indicated by dash-dotted lines) in the existing structure. The arrow 6 indicates where the reinforcement 16 is welded to the carrier 2.

FIG. 2 also shows how and where the other support 3 is welded in the upper region of the side wall 4 of the existing structure 1. The bracket 17 attached to the deckhouse module 10 stands on the support 13 and is welded to the arrow 7 at the location thereof. In order to also be able to absorb sufficient transverse forces, the weld seam at point 7 is designed in the form of a trapezoidal wavy line, which is achieved by means of corresponding incisions in the lower surface of console 17.

2 that the welding areas 6 and 7 are easily accessible even when the deckhouse module 10 is in place. In addition, this figure shows that by welding the supports 2 and 3 from the outside of the deck surface 5 and the side wall 4 of the existing structure 1, heat is generated only on the outer skin and hardly reaches the interior with the corresponding equipment parts, so that no damage is to be feared.

3a - 3c three different variants A, B and C are shown schematically. Type A according to FIG. 3a corresponds approximately to the embodiment according to FIG. 1 and is of one-story design. Type B according to FIG. 3b has two floors and contains an additional ceiling 18b and a balcony 20b arranged in front of it for the second floor. At the same time, it is indicated that this module according to FIG. 3b has a larger overhang compared to the existing structure 1 and must therefore be supported by an additional support 19. The cabin width of the lower part is larger than in the embodiment according to FIG. 3a and for this reason is provided with an additional inner support 19b. Finally, FIG. 3c shows a further enlarged type C, in which additional supports 9c are provided at corresponding locations because of the greater width.

3a-3c, the reference numerals for the front wall 12, the floor 13, the ceiling 14 and the rear wall 15 are provided with corresponding additional letters a, b and c, respectively.

The grid with respect to the position of the chamber partition walls 22 and the posts 12a to 12c between the windows 12d will now be explained with reference to FIGS. 4 and 5. In these figures, three deckhouse modules, module 10a, module 10b and module 10c, are provided, which are separated from one another by interfaces 26, through which the welded connections between the individual modules are also made. It can be seen that in the region of the interface 26 or the ends of the deckhouse modules, the chamber partition walls 22a do not run through the interface 26 or lie thereon, but are offset by a distance x from the latter. The (in the drawing) inner ends of the modules 10a and 10c are thus closed by chamber walls 22a, and the modules standing next to one another are welded outside the space closed off by the chamber partition walls 22a. In contrast, in the inner module 10b, corresponding chamber partition walls are missing in the end region; the corresponding chamber is separated in the finished state by the respective chamber partition 22a of the adjacent module. The remaining chamber partitions 22 do not interfere with the connection of the individual modules to one another. So that the interior of the middle module 10b is not impaired or soiled during the assembly and welding work on the interface 26, the end regions of the module 10b are separated by provisional partition walls which are spaced from the end in such a way that working on the interface 26 is possible without hindrance. These temporary partitions will be removed later.

FIG. 4 also shows chamber ceilings 21 and 21a, the chamber ceiling 21a in the region of the interface 26 only being hooked on subsequently.

The installations, indicated by the reference symbol 29 in FIG. 4, are installed in the individual deckhouse modules 10a, 10b and 10c; they only need to be connected by connecting links such as sliding sleeves 28 or the like. can be connected to one another without any intervention in the interior of the modules. Likewise, the insulation 23 can be completely installed in the modules, it only has to be completed in the area of the interface 26.

5 now shows the front wall 12 of the deckhouse modules 10a, 10b and 10c with corresponding windows 12d. As can be seen from the drawing, the posts 12a have a width of 6x, where x relates to the thickness of a chamber partition 22, 22a and the offset of the chamber partition 22a with respect to the interface 26. The posts 12b at the end of the deckhouse modules are only half the width 3c, so that after the welding of the outer surfaces of these supports 12b there is a full width of 6x and thus a uniform appearance of the window front. The uniform offset x of the chamber partition walls 22 and 22a relative to the one outside of the posts 12a and 12b results in the same chamber length y for all chambers.

4 and 5, the deckhouse module 10b is a special module in such a way that a fire bulkhead 25 is provided in the central region. These fire bulkheads are to be arranged at a distance of at least 40 m in accordance with the applicable regulations, so that this safety distance can be maintained by a corresponding combination of "normal" deckhouse modules with such special modules. Due to the increased space requirement of the fire bulkhead 25, in order to achieve the same chamber lengths y, it is necessary to widen the post 12c located in this area to the dimension of 9x. An increase in the length of this special module 10b can be limited by the fact that the displaced chamber walls 22a are missing at the two ends of this module, and the corresponding separation is formed by the chamber partition walls 22a of the neighboring modules 10a and 10c.

6 now shows how a fully equipped deckhouse module 10 can be transported through a special traverse 30. This special traverse 30 is designed as a stable frame with side members 32 and cross members 33, and at the appropriate points 10 load eyes 31 are attached in a certain grid according to the dimensions of the deckhouse modules. These load eyes 31 engage via tensioning screws 35 on correspondingly welded load eyes 11 on the deckhouse modules 10 in order to support the deckhouse modules 10 during transport and in such a way that they cannot deform beyond a certain extent.

The distribution of the loads is adjusted by adjusting the tensioning screws 35 accordingly. The special traverse 30 with attached deckhouse module 10 is or the like on appropriate ropes 34 by a crane. raised.

Transport by means of this special traverse 30 is necessary since the individual deckhouse modules 10 or A, B, C (FIGS. 3a to 3c) do not have sufficient torsional and bending strength, but are only stabilized when they are on the supports 2 and 3 placed on the existing structure 1 of the ship and fastened there.

Fig. 6 also shows that the individual chambers of the deckhouse module 10 are already fully equipped and furnished, including the corresponding furniture, which only has to be pushed back from the interface 26 to weld the individual deckhouse modules together. 6 also shows that the individual chambers are separated from a corridor by a rear chamber partition wall 22b and that this chamber partition wall 22b ends at a distance from the interface 26. This separation is only continued after connecting to the next module.

In addition to the above description, it is added that the fastening, in particular welding of the beams 2 and 3 to distribute the load on the existing superstructure 1, does not have to take place in the shipyard during the conversion, but can be carried out before the ship arrives, since the cabins underneath not be affected because the attachment is done from the outside. This work can be carried out, for example, in other ports or even while sailing.

The deckhouse modules, as shown in FIGS. 1, 3a and 6, have a length of 16 m and are so unstable in separate form that without the use of the special traverse 30 such strong deformations or deflections would result that they would deform permanently and the windows would partially break. In addition, installations and equipment would be damaged. By using the special traverse 30 deflections are limited to a few millimeters.

While the deckhouse modules shown are open on both sides, it goes without saying that end modules must be provided with a corresponding end wall. However, this does not change the principle of the present invention. It is particularly important that the individual deckhouse modules 10 can be manufactured precisely and fit exactly to one another due to the completely flat contact surfaces on the supports 2, 3, without lateral additions, as was previously customary in shipbuilding, being necessary and having to be cut to size subsequently.
