Description

Equipment Outfitting Methods and Modules

The invention relates to a solution for transporting and installing equipment components inside a ship to be installed in shipbuilding. More precisely, the invention relates to outfitting methods and modules for preassembled equipment components such as air conditioning systems and engine compartments.

Ship construction generally includes many different operations, such as for example the manufacture of hull sections, the assembly of the hull from said sections and several different outfitting operations depending on the hull assembly plan until the completion of the ship. The number of various components to be installed in various outfitting operations is enormous, which is why, as is known in the prior art, various modular solutions have been proposed for various installations and operations to simplify and rationalize these assignments. Such modules are generally prefabricated and ready separately from the hull building process and planning and delivered to the dock at a time suitable for outfitting. An example of a typical module to be outfitted is a ship's hold.

Modular solutions have also been applied in the outfitting of a wide variety of structurally heavy objects such as complete units, machines, equipment and entities made of them such as ship fan rooms and engine equipment. But with regard to the use of modular structures, the heavy planning of these structures has raised concerns from a shipbuilding point of view, such as the fact that the modular frames are quite heavy, and the final connection becomes more difficult due to the space required by the modular frames, maintenance operations It becomes more difficult, the conditions of the end user being tied down and the number of hours of hot work and installation while the module is in place increases significantly. Consequently, the benefits brought about by modularity in these plans have actually degenerated into additional costs, excess weight and increased space requirements relative to conventional shipbuilding. These disadvantages are why modularity has rarely been applied in these plans after early experiments.

In particular, the modularization of such plant and equipment entities is problematic in operational planning where the modules of the plant and/or plant entities extend vertically over at least two paved decks, e.g. for the This is generally the case for air conditioning units installed into ship fan rooms. A similar situation may also arise in the case of so-called engine shafts of ships. The problem of modularity of this type of planning then becomes complicated.

The solution of the present invention provides the ability to completely eliminate or at least substantially alleviate the above-mentioned modularity problems of existing known heavy-duty plants and/or plant entities.

In one solution according to the invention, machines, plants and/or other types of plant entities are modularized in such a way that, during modular prefabrication, plants and machines are mounted to modular frames. At this stage of prefabrication, the modular frame is a self-sustaining structure that generally includes a number of horizontal and vertical supports. The process of moving a module on board, and in particular hoisting it on board, involves removing the lowest section component of the module frame, that is, the section forming the bottom of the frame, and removing the vertical connection between the bottom of the frame and the next section or platform. Or multiple sections or components connected by multiple platforms. During module prefabrication, the lowest equipment part of the module has been mounted on the highest platform or the next platform of the module frame by means of a suspension mechanism, whereby the lowest equipment part remains Suspended from the remaining module upper frame. In addition, the modular frame is constructed in such a way that its vertically extending frame components, including possible diagonal braces, can be removed after module outfitting.

This allows to minimize the space occupied by the module frame in the fixed modules, thus providing space around the fixedly installed plant components for required retrofitting work and plant maintenance. In addition, the excess weight added by the modules to the gross weight of the vessel can be minimized by the removable components of the module frame.

The removable frame components of the modules of the present invention are also preferably fixed in place on the module frame by bolts or screws with flange connections, preferably arranged in a vertical direction relative to the modules. In the plane where the plane is inclined. This provides the ability to minimize the high temperature work required and the resulting disadvantages associated with module installation, moreover, the flange connection arranged in an inclined plane enables removal of the removable module frame from the fixedly mounted module Components just got easier. Removable components are also suitable for re-use in subsequent prefabrication of similar modules.

In a solution according to the invention the modular frame is preferably constructed in such a way that it extends vertically to the deck surface of the multi-storey ship, the modular frame is equipped with machines and equipment contained in several different cover structures, And the modular structure is formed with lightened horizontal planar structures which are adapted to sit flush with the deck of the ship once the module has been installed in place. The modular construction according to the invention can then also be used in the construction of machinery and equipment extending up to the engine compartment of a multi-deck ship. In addition, the lightened horizontal plan structure of the module is structurally lighter than conventional ship deck structures, which allows for further weight reduction of the module.

A module according to the present invention extending over a plurality of ship deck surfaces is preferably fixed in place such that, during placement of the module, the horizontal planar structure of the module rests substantially flush with the deck on a surface extending from the ship structure. over the raised protrusions, and the horizontal planar structure of the module is fixed to these protrusions. Such module securing simplifies and speeds up the securing of the modules in place, especially when the modules are lowered into their assigned positions within the vessel.

The lowest suspended equipment entity of the module of the present invention is preferably fixed to the deck structure forming the floor of the space designated for the module, thus allowing at least partial removal of the frame components employed in the suspended installation of the minimum equipment entity .

The invention will now be described in detail with reference to the accompanying drawings, in which:

Figure 1 schematically shows a three-layer embodiment of a module according to the invention,

Figure 2 schematically shows a two-layer embodiment of a module according to the invention.

Figure 1 schematically shows a three-level embodiment of a module 1 of the invention relating to a fan room unit intended for air-conditioning equipment and extending vertically to three ship decks.

The frame 2 of the module 1 consists of a three-layered horizontal planar structure, ie the base structure 3 of the frame, cover structures 4, 5 and vertical beams 6, 7 which connect these horizontal planar structures to each other. On top of each horizontal planar structure 3 , 4 and 5 is mounted a respective air conditioning unit 8 , 9 and 10 .

The process of manufacturing the module 1 of the invention as shown in FIG. 1 consists first of all in constructing the floor structure 3 of the frame 2 on which the minimum air conditioning unit 10 is placed. The underside structure 3 for the frame 2 of the module 1 is preferably made of only a few horizontally extending beams or tubes and frame support beams 16 which provide the required support points for hoisting the lowest air conditioning unit 10 Together with the remainder of the module frame, the frame braces extend horizontally near the edges of the floor structure of the module frame.

This is followed by mounting in place the next cover structure 4 comprised by the frame 2 of the module 1 . The cover structure 4 is preferably assembled as a single entity comprising the lowest vertically extending uprights 6 and braces 16 extending in the horizontal plane of the floor structure 3 and interconnecting the lower ends of these uprights, said monolithic entity It is then hoisted above and around the lowest air-conditioning unit 10 and the bottom structure 3 below.

Once the frame 2 of the module 1 contains the cover structure 4 and its supporting structure together with its vertical beams 6 and its support beams 16 extending at the level of the floor, the lowermost air conditioning unit 10 and with the floor structure 3 The aligned support structure is connected to the cover structure 4 by vertically extending suspension beams 11. In addition, an intermediate air conditioning unit 9 is installed on the upper surface of the cover structure 4 .

Next, the highest cover structure 5 contained in the frame 2 of the module 1 and the vertical beams 7 securing it to the module frame are installed in place, followed by the installation of the highest air conditioning unit 8 on the upper cover structure.

Once the frame 2 of the module 1 has been completed, the installation of the air conditioning units 8, 9 and 10 can be completed, as can the installation of the required fittings and the module 1 can be assembled with the required fittings and components.

The intermediate cover structure 4 and the uppermost cover structure 5 comprised by the frame 2 of the module 1 of the invention are provided with the platforms required to work on these cover structures. In addition, the edges of the cover structures 4 , 5 are provided with projections 12 and 13 in the form of horizontally extending beam ends.

The process of moving the complete prefabricated module 1 on board includes first hoisting the module 1 to a suitable height, eg about 1/4 meter from the lifting eye 14 of the highest capping platform. When the module 1 is being suspended, the frame 2 of the module has removed the lowest vertical beams 6 and the support beams 16 extending horizontally at the bottom edges of these vertical beams. Therefore, the lowest air-conditioning unit of the module 1 is suspended on the middle cover structure 4 of the module by means of the suspension beam 11 and the remaining floor structure 3 .

Once the frame 2 of the module 1 has its lowest supporting structure removed, the module is hoisted aboard to its designated space. At a later stage of lifting the module into place, the protrusions 12, 13 extending from the edges of the cover structures 4, 5 of the module frame 2 are placed over the protrusions protruding from the walls of the space designated for the module, so that The wall protrusions are substantially flush with the water level of the respective ship's deck structure.

Once the module 1 is outfitted in its assigned space, the protrusions 12, 13 of the frame 2 of the module are welded to the joint with protrusions protruding from the vessel structure and the vertical beams 7 are removed from the module frame. remove. In addition, the lowest air-conditioning unit 10 is fixed in place to the ship deck structure forming the floor of the space designated for the module 1 , the lifting beams 11 are then disengaged from the module frame 2 and the remaining in the floor structure 3 of the module frame is removed. supporting system.

The module 1 has then been successfully placed in place and a connection can be established for the mains of the air conditioning units 8 , 9 and 10 to the mains of the ship.

In the frame 2 of the module 1 of the invention, the horizontally extending cover structures 3, 4 and 5 mounting the vertical girders 6, 7 and suspension beams 11 to the frame are preferably formed by inclined flange connections 15 with bolts. Thus, the separation of the vertical beams 6 , 7 , the cross beams 16 and the suspension beams 11 from the rest of the frame 2 is successfully achieved, even if the vertical beams would otherwise be loaded after the module installation, for example from errors. The high-temperature work required during the operation of separating the vertical beams 6, 7, the cross beams 16 and the suspension beams 11 can then preferably be dispensed with.

In the embodiment of FIG. 1 , the cover structures 4 and 5 contained in the frame 2 of the module 1 are left as part of the ship's deck structure. With such modularity, the cover structures 4 and 5 of the module 1 can be easily and economically provided with a lighter construction than the rest of the ship's deck structure.

Figure 2 schematically shows a double-deck embodiment of a module 21 of the invention relating to a fan room unit intended for air conditioning equipment and extending vertically over two ship decks.

This embodiment more clearly embodies a vertical suspension beam 26 which provides a suspension mechanism for an air conditioning unit 25 mounted above a floor structure 23 contained in the frame 22 of the module 21, said suspension beam being in contact with The vertical beams 27 of the module frame are separated, said vertical beams being detached from the module frame at an early stage of moving the modules to their destination.

With respect to the embodiment of the invention as shown and described above it should be noted that the invention is in no way limited thereto. The modular solution according to the invention can likewise be applied in the outfitting process of other equipment entities than air-conditioning units, such as eg equipment assemblies for elevators and engine compartments. The modular solution according to the invention can also be modified in many ways obvious to a person skilled in the art within the scope of protection defined by the appended claims.
