Definitions

• the present invention relates to a method in accordance with the preamble of claim 1 of manufacturing a floating structure, for instance a watercraft, in which method a hull part for the floating structure is formed, it is provided with deck structures or similar support structures, and space units to be installed between said deck structures or similar support structures are prefabricated.
• DE1808781 A1 discloses a solution, where the sanitary cabins, i.e. WC and shower units, of two adjacent cabin units are interconnected and can be transferred and installed as one pre-furnished unit.
• the cabin spaces related to these sanitary units are, instead, built on site onboard the watercraft around the sanitary cabins.
• an essential part of the manufacturing and installation of the cabins is, according to this solution, still performed onboard.
• FI20030352 An example of the former is disclosed in FI20030352, where the upper parts of the cabin units are lifted so that they are located between the deck beams, and the lead-ins of various pipes and cables are arranged individually on each deck in a suitable manner so that the number of through-holes in the deck beams can be minimised, whereby the deck beams may be made lower without compromising on their strength properties.
• WO2004/041633A1 An example is disclosed in the above-mentioned WO2004/041633A1. In an arrangement according thereto every second deck may completely omitted.
• a purpose of the present invention is to provide a novel solution, by means of which the prefabri cation and outfitting of cabin units may to an increasing extent be moved to better circumstances on plant, and thus to further minimise the installation work carried out on watercrafts, often in hard conditions.
• a purpose is also to enable the lowering of the deck height or the centre of gravity of watercrafts as well as to improve the utilisation of cabin units and the spaces related thereto. Further, a purpose is to improve the use of materials and to simplify and speed up the installation of cabin units onboard the watercraft.
• space units are manufactured comprising engineering units and room units so that an engineering unit interconnected with a room unit makes a cabin unit.
• the engineering unit is provided at least with WC-equipment and a passage to its respective room unit.
• the engineering units of two adjacent cabin units are prefabricated and connected to one another to form an engineering unit pair and the thus accomplished engineering unit pair is transferred to and installed in its place on a floating structure.
• Engineering unit pairs are arranged successively within the deck structure so that they abut onto a cabin corridor and define the width of the cabin units facing the cabin corridor.
• the floating structure is provided with a number of vertical support elements, such as stanchions, to be installed between the deck structures preferably prior to the installation of the engineering units.
• an engineering unit pair may be provided with various common elements, the coupling means of each individual cabin may be mounted in advance and the unit may also be equipped with elements for the immediate environment of the cabin units.
• an engineering unit pair is easier to transfer to and install in its place between the stanchions than an entire cabin unit. This, among other things, enables the changing of the mutual distances related to deck beams and their vertical support elements so that the deck height can be reduced and/or space utilisation improved.
• the room units for the engineering unit pair are prefabricated and transferred into their places preferably as one unit and connected to the engineering unit pair as well as to the deck structures or similar support structures of the floating structure.
• the room units may thus also be furnished in advance and provided for instance with a window and/or a balcony, if required.
• the cabin units are preferably arranged in rows within the deck structure so that a corridor is formed between the rows.
• the deck beams or the like included in the deck structure may preferably be supported by said vertical support elements at two different points on different sides of the corridor. Due to the accomplished additional support, the deck beam itself may be made lower, without compromising on the strength properties, than in a traditional arrangement, where the deck beam is supported only at one point.
• said vertical support elements are preferably installed so that they are located between an engineering unit and a room unit, when they are installed in place.
• the engineering units of an engineering unit pair are equipped with a recess in the wall for said vertical support element.
• the vertical support elements are most preferably mounted in advance prior to the installation of space units. In principle it is, as well, possible to install them or a part of them also afterwards, e.g. after a part of the cabin units has already been brought onto the watercraft, in which case they are welded onto the deck structure and deck beams. This might, however, result in damages to the cabin unit as well as in a higher fire safety risk.
• the installation of support elements also delays the outfitting work carried out onboard.
• the engineering units of an engineering unit pair may preferably be equipped with a common partition, which tends to reduce the weight of the structure.
• Other elements possibly shared by adjacent cabin units are e.g. an air- conditioning unit.
• the engineering units of an engineering unit pair are equipped with a passage to their respective room units and with an entrance door from the cabin corridor to a cabin unit. Then the engineering unit preferably defines the width of the entire cabin unit facing the cabin corridor.
• the successively installed engineering units preferably form the wall of the cabin corridor, whereby the engineering unit pair may be further equipped with a pre-installed furnishing wall facing the cabin corridor and a common service space opening to the cabin corridor.
• the wall of the cabin corridor is preferably equipped with a service door to the service space.
• the engineering units and the ceiling structure integrated with them are preferably made lower than the room units in the vertical direction, whereby the space above the engineering units and/or the ceiling structure of the corridor is available for instance for leading in and coupling the pipes, conduits and cables of the HEVAC systems with the cabin units individually on each deck. Accordingly, the room units may be made higher and their ceiling may be provided, in a manner known per se, with foldable beds etc.
• the present invention also relates to a building system according to claim 12 and a floating structure according to claim 23 with respective dependent claims.
• Figure 2 shows a side view of the differences between a traditional prior art solution and the technical solution according to the invention and the impact of these on the mutual distances between the support structures, i.e. on the module pitch;
• Figures 3 - 5 show, step by step, how the space units are installed and assembled in place on a floating structure in order to provide cabin units according to the invention.
• Figure 6 shows the structure of the cabin area assembled and installed according to the invention seen from above.
• Fig. 1 the transfer and installation of cabin units onto a watercraft or the like is carried out in the way shown in Fig. 1. Accordingly, prefabricated self- supporting cabin units 1 ' provided with a WC unit 1 'a and an entrance door 1 'b are brought one by one, as shown by the arrows, between the watercraft's outboard structure 2', inner support structure 3' and the vertical stanchions 5' of deck beams 4', into their places on the deck 19' of the watercraft. Conventionally, only every second deck beam 4' is supported by a stanchion 5' in order to facilitate the installation of the cabin units 1 '.
• decks on the watercraft there may be, as known per se, several decks on the watercraft and they are supported by means of said parts 2', 3', 4' and 5', and in addition, deck beams in the longitudinal direction of the watercraft, which are placed transversely with respect to the deck beams 4', as shown in the figures, are used.
• deck beams in the longitudinal direction of the watercraft which are placed transversely with respect to the deck beams 4', as shown in the figures, are used.
• the rest of the watercraft's structure is not shown in detail, as it is not as such relevant to the application of the invention.
• the cabin units 1 ' are installed in rows on the deck 19' so that a cabin corridor 6' is formed between them and the pitch of the cabin units is determined by said deck beams 4' and on the other hand, by the stanchions 5'.
• the cabin unit 1 ' is adapted into the outboard structure 2' by means of a lining 7'. Every cabin unit 1 ' is then coupled separately with the systems of the watercraft, e.g. the HEVAC systems, which are not for the sake of clarity shown here separately.
• the aim is to provide these various couplings by utilising, if possible, the service space 10', known per se, arranged between the cabin units.
• the ceiling of the cabin units may be brought into its place at the same time or it may be mounted separately between the deck beams 4'.
• the lining of the cabin units on the corridor's side is carried out on site by installing furnishing walls and ceiling boards as well as other technical equipment required by the corridor, e.g. lighting and air conditioning (not shown in detail), between the cabin units and the cabin corridor.
• the linings 7' against the watercraft's outboard structure 2', possible balcony assemblies etc. are provided.
• Fig. 2 illustrates the differences between an old and new installation method and system.
• the upper part of the figure shows the old method, whereby the module pitch parallel with deck beams is determined by the position of the stanchion 5'.
• the lower part of the figure which is according to the invention, shows that a cabin unit 1 is for prefabri cation and installation divided into separate engineering units 9 and room units 8, whereby the stanchions 5 have been mounted on the deck 19 so that they may be placed between the engineering unit 9 and the room unit 8 and not in conjunction with the cabin corridor 6 between the cabin unit rows, as was the case earlier.
• the module pitch has thus changed and the deck beam 4 is supported at two points by the stanchion 5.
• the deck beam 4 may be made lower without compromising on the strength of the support, as the span is shortened as well.
• the engineering units 9 according to the invention are made lower, whereby the space above them may be used for leading the pipes 15 and cables 16 of various systems into the cabin units 1 on each deck, as is shown in more detail in FIG. 6.
• the room unit 8 may be made higher, whereby the extra room may advantageously be used e.g. for installing so-called Deck Pullman beds 17.
• a ceiling dome provided with decorations 18 may be, if desired, lifted afterwards into the space between deck beams above the ceiling surface of the room unit.
• the deck height may by means of the lower deck beams be reduced as well, whereby the centre of gravity of the watercraft can be lowered.
• the number of decks may be increased, whereby more cabin units can be provided on the watercraft and thus the passenger capacity increased.
• Fig. 3 shows the basic idea according to the invention of joining together and prefabricating the engineering units 9 of two adjacent cabin units to form an engineering unit pair 12, which is then transported and moved to its place between stanchions 5, as is shown by the arrow.
• both engineering units 8 of the engineering unit pair 12 comprise a WC-unit 9a, corridor door 9b, passage 9c to the room unit of the cabin unit and a recess 9d for the stanchion 5.
• the engineering units 9 have a common partition 9e.
• the engineering unit pair 12 is also provided with a service space 10, in which accessories and equipment related to the cabin units, such as pipes, cables and conduits for coupling the units to the systems of the watercraft and/or to make them a part of the relevant systems, may be installed.
• the cabin units may also have e.g. a common air conditioning unit, which is connected to the engineering unit pair 12.
• the engineering unit pair 12 may preferably be in advance provided with a furnishing wall 1 1 to be adapted to the cabin corridor 6. This may be preferably provided also with technical equipment for the corridor, such as the installation of fire fighting equipment, lighting, communication system etc.
• the engineering unit pairs 12 for the cabin units at least within a certain area on a particular deck of the watercraft are transferred to and installed in their places between the stanchions 5. Between the successively installed engineering unit pairs 12 remains a cabin corridor 6.
• the room units 8 for the already installed engineering unit pairs 12 are transferred to and installed in their places.
• the room units may be transferred one by one, but preferably in pairs, as shown by the arrows, since the pitch of the stanchions 5 and the selected tolerances make this possible.
• the room units 8 may also be made unequal in size, if so desired.
• the prefabrication degree of the room units may be chosen, if required, so that the room units are provided e.g. with furniture, a window, balcony etc. already prior to the transfer of the room units into their places, if so desired or required by the situation.
• the engineering units are preferably outfitted as completely as possible in advance in order to minimise the installation work carried out onboard the watercraft.
• the engineering unit is provided in advance preferably at least with sanitary facilities, a service space with equipment and technical couplings for the cabin unit.
• the engineering units can in principle also be installed so that they are not actually located between the stanchions, but the stanchions remain between the engineering unit pair and the room units in the cabin unit's centre section.
