Description

Construction of ships in docks or on Helgen.

When building ships in docks or on Helgen, the Usually proceeded in such a way that the entire hull or hull incl. the deck superstructures (e.g. navigating bridge) in the dock or on the Helgen Will.

Then the launch takes place or becomes the dock for the next one Build free. The equipment of the engine rooms that was not yet completed when the ship was launched and the final installation of the main superstructures must then be carried out after the discharge respectively.

after the ship has been launched at equipment piers.

Such a shipbuilding method takes the most expensive manufacturing equipment the shipyard, i.e. the construction dock or the Helgen and the equipment pier, proportionately a long time to complete. On the one hand, the hull can support the dock or

Do not leave the Helgen until the one to accommodate the machines and engine rooms certain sections of the ship's hull up to the buoyancy have been completed, which takes longer than assembling those Sections, the only holds or the like. contain. This disadvantage is particularly important when the hull of the ship is the largest, as is the case with freighters, bulk carriers and tankers Part of its length only holds or only more or less uniformly formed and encloses simply furnished rooms, such as for simple passengers or ferries. On the other hand, the relatively lengthy equipment work in the engine rooms, as well as the setting up of the deck superstructures and their equipment Do not even begin before assembling the hull or the superstructure has reached an advanced Monday state. The consequence of this is that the equipment pier correspondingly long until the completion of the equipment work is needed.

The object of the invention is now to build such ships @@@@ in Docks or on Helgen to make it more profitable that the necessary stay duration of the hull in the dock or the like. is only slightly longer than the time which is required to contain the holds or simply furnished rooms Assemble parts of the entire hull of the ship. The basic idea of the invention can be seen in it, the beginning of hull sections with engine rooms and / or any construction and equipment work required for deck superstructures to bring forward that this work has already largely, e.g. about half, been carried out are when in the dock or on the Helgen with the keel laying of the other hull parts is started. In this case, the time of the construction can be programmed in such a way that that when reaching the buoyant state of the predominant part of the hull also the engine room sections and the deck superstructure units so far manufactured and are equipped so that they can immediately deal with those in the dock or on the Helgen Ship parts can be connected and the ship immediately afterwards a the dock can be funneled or left from the stack.

T) a the intricately equipped engine room sections and deck superstructure units have already reached a high level of production at this point the ship is only a short time at the equipment p until the final Ealbeenigung he too llegell.

According to the invention, these advantages are achieved in that in the building dock or on the Helgen only holds or the like.

containing parts of the entire hull are assembled, during the assembly and fitting out of those hull sections, the engines or engine rooms included, and / or of deck superstructures in the outside, however Assembly sites close to the building dock or shelter in advance take place and the finished or

almost completely equipped hull sections or

Superstructure units the rest of the hull parts resting in the dock or on the Helgen for cultivation, i.e. to complete the entire hull of the ship.

A shipyard facility for carrying out such a construction is marked by arranged in close proximity, but outside the building dock or the Helgen Assembly sites for assembling and equipping machines or

Hull sections and / or deck superstructures containing engine rooms, wherein transport tracks are provided for feeding the finished or almost manufacture sections or units from the assembly sites to those in the dock or on the Helgen located parts of the hull are used and are guided in such a way that the sections or

Units exactly in the positions opposite the dock or the like. located. Get hull parts in which they are connected elmittelbar with these parts can be.

If the ship is built according to the procedure outlined above in such a shipyard, the dock or the helgen only needs that way It takes a long time to be done, as it is just assembling the Holds od, the like. containing part of the entire hull and connecting the finished or requires almost completely equipped sections or units with this part. During the much longer time, on the other hand, the assembly and the equipment of the engine rooms and / or the deck superstructure units, the dock can use other z, B, for further new builds, conversions or repair work on finished ships be exploited. In this way, the existing production capacities can be used Use the shipyard much more intensively and cost-effectively than before. It exists also the advantage that it is required in the assembly facilities if necessary a plurality of engine room sections or deck construction units at the same time can be put into work. The most advanced in terms of equipment Shortly before the ship is launched, the section or deck structure is then put into the Dock or on the Helgen finished hull parts for attaching and connecting and the following sections or structures in the production state are supplied advanced to the last production position of the assembly site. This is done in this way the assembly and disengagement in the assembly facilities in the manner of an assembly line, which can be carried out in weather-protected workrooms.

Further details and advantages of the invention emerge from the The following description of an embodiment illustrated in the drawing a shipyard for the management of the new shipbuilding method.

1 shows the shipyard facility equipped with a building dock in plan; Fig. 2 is a section along the line A - B of Fig.

In a building dock 1, the one with a rock gate 2 opposite the harbor basin is lockable, there is the one consisting of a number of holds 3 Part 4 of a ship's hull under construction. The construction of this predominant Part of the hull takes up due to the simple design and equipment of the Relatively few cargo spaces (e.g. tanks, simple living quarters or the like) Time to complete. Nevertheless, it will be after the completion of most of the hull not possible to dock at this point for the bam of a following ship to clear, as the - in the illustrated embodiment at the stern of the ship lying machine room section 5 to be completed at least up to floatability is. However, its assembly is due to the machinery provided therein not as quick as assembling the rest of the hull.

Only when this ship section 5 is able to vibrate can flood the trestle and clear gate 2 for the next building.

Likewise, the ship must be waited before undocking until until the basin superstructures 6 have been erected on the upper deck of the hull 4.

According to the invention, the depicted shipyard is now with -side next to building dock 1, i.e. assembly sites located directly outside the building look 7 and 8 equipped. In these assembly facilities - independent of time and space of the work carried out in the corner - assembling and equipping the machines or ship sections 5 containing masohine rooms on the one hand and the deck superstructure units 6 on the other hand.

The assembly sites 7 and 8 are appropriately covered so that in them work regardless of the prevailing weather conditions can.

The assembly sites are also set up so that on several ship sections 5, 5 ', 5 "or build-up units 6, 6' can be worked at the same time.

Around the dock l @@@@@@ considering the long construction time of a Section 5 or a unit 6 unnecessarily requires the keel laying in the Docl. to take place only if the started with a corresponding time limit Section 5 or unit 6, for example, have been approximately half completed.

If the cultivation readiness has been achieved, section 5 and the assembly unit 6 with the aid of, for example, slideways 9 and 10, respectively Transport lane those points of the part 4 of the entire hull located in dock 1 fed to which they are to be connected to these. In the illustrated embodiment the engine room section 5, which at the same time forms the spot of the ship, led behind the aftmost cargo hold 5 and connected here to the ship's hull.

Then the to be placed on the upper deck of section 5 Construction unit 6, which contains the Xommandostand resp.

the bridge of the ship with all necessary equipment and control devices etc forms the hull 4 from the side in the plane of the upper deck and connected to the engine room section 5.

The assembly sites 7 and 8 are designed and dimensioned so that if necessary, several machine room sections 5, 5t and 5 ", etc. and several structural units 6, 61 etc. can be genomined in work at the same time, proceeding in this way that the component 5 or 6 closest to the dock 1 or hull 4, respectively has the highest level of completion and after completion of the assembly of the holds 3 can be brought to cultivation immediately. Once this has happened, the next following Section 5 'or the closest assembly unit 6' in the parts previously described 5 and 6 assumed cultivation readiness positions transferred, it is on this Way a conveyor belt-like production of sections 5 and units 6 enables.

In addition, this design ensures that the dock 1 during a considerable part of the time that is spent in the assembly facilities 7 and 8 production and equipment work is required, otherwise, i.e. e.g.

for further new buildings, conversions or for repair work on manufacture Ships, can be exploited.

As Fig. 2 shows, the assembly sites 7 and 8 and those in them provided transport or slideways 9 and 10 in such levels compared to the Hull 4 created in the dock is laid out so that the engine room units 5 and deck superstructures 6 easily into the Positions can be brought in which they can be connected to the hull 4 are, The arrangement of the assembly sites 7 and 8 relative to the building dock 1 depends of course from the overall construction of the

of the ships to be built in the dock. Are the superstructures e.g. in the to put on the front part of the ship, the assembly site 8 is accordingly further to be provided at the front end of the dock, on the other hand predominantly ships built whose engine rooms are more in the middle of the ship, so one will Arrange the assembly site 7 to the side approximately next to the center of the dock.
