METHOD AND SYSTEM FOR INSTALLING AND CONNECTING PREPARED ROOM UNITS 5 TO A VESSEL OR OTHER WATERWAY VEHICLE - FÖRFARANDE OCH SYSTEM

The invention relates to a method according to the preamble of claim 1 and to an installation system according to the preamble of claim 13 for mounting and connecting prefabricated room units to a vessel or other craft.

15 It is previously known to fit cabins on board ships so that the prefabricated cabin is brought to the deck on which the cabin will be installed during the construction period. Each cabin deck shall be provided with its own ship deck intermediate deck with a single deck above. Each cabin is lifted individually on board, transported on board, and individually connected to ship systems, such as 20 HVAC, fire extinguishing, monitoring, etc. systems, which, despite prefabricated cabins, still has a great deal of work on board, which can unnecessarily extend ship construction time.

It is an object of the invention to provide a new improved and more efficient installation method and, accordingly, an installation system which allows the installation work to be performed more and more in advance before the cabin or room units are moved on board and installed. The purpose of the invention is not only to save work, but also to make material adjustments in the construction of the cabin compartments of the ship.

The object of the invention is achieved by the installation method according to claim 1 and the »* * according to claim 13; : with the installation system and as further specified in other requirements.

According to the method according to the invention, at least two room units; : 35 are supported and connected vertically directly to form room unit group 2 116049. A group of room units is fitted between two structural decks by moving the room units to the ship parallel to the structural deck.

By joining the room units together as a group of room units in this way, installation can be substantially accelerated and simplified, thus reducing the time it takes to build a ship. As the amount of installation on board decreases, there is also an improvement in quality. At the same time, installation makes it possible to dispense vertically between the room units with no separate intermediate deck of the ship's actual hull structure 10, but to replace it with an assembly of connected room units. Thus, every other cabin deck can be omitted from the hull structure. As a result, the ship's side height is reduced and weight is reduced, allowing more cabins to be fitted, particularly in the case of heavier-critical passenger ships, than by known methods and arrangements.

Advantageously, based on the above, most of the room units are transferred to the ship as groups of room units, whereby the savings in installation are correspondingly greatest.

If necessary, the room units of a group of room units may also be transferred individually to one ship, such that one room unit comprises a structural element belonging to another room unit. Thus, before attaching the room units v1: to the other, the lower room unit can advantageously be provided with the floor structure of the upper room unit. In this case, it is preferable to; - 25 proceeding by moving a plurality of lower room units to the ship and installing them in a substantially final position such that the floor structures of the upper cabins attached thereto constitute at least a substantially uniform lightweight deck. A number of upper room units are then transferred to the ship and transported on board by utilizing said deck level 30.

:; Alternatively, it can be done so that before the room units; attaching each other to the upper room unit is provided with a floor element that functions at least as part of the roof structure of the lower room unit. In this case, however, the transport level provided by the lower room units 3 116049 cannot be utilized, but again in this case a separate ship structural deck between the room units is not required.

The plurality of room units may also advantageously be provided with a horizontal support structure 5 such that said support structures together form at least part of the corridor structure and / or deck structure and / or other floor structure associated with the installed room units of the ship.

HVAC and / or other systems of 10 vessels to be connected to adjacent room unit groups on the same plane are preferably guided mainly horizontally between the room unit groups and the structural decks. For example, air conditioning and sprinkler pipes are preferably routed between groups of room units and the structural deck of a vessel above them. In this case, connections of the lower room unit of the room unit group to the ship's systems are provided through at least 15 mainly upper room units. Instead, downstream black and / or gray water may also be conducted as needed with horizontal drawings below the cabin unit groups, whereby the upper room unit would be connected to the system via the lower room unit. In any case, the HVAC and / or other systems of the room units of the prefabricated group of room units are preferably connected to each other before being transferred to the ship.

The installation system according to the invention is also based on the fact that at least two prefabricated room units are arranged to be supported and connected vertically directly to form a group of room units ·: 25. A group of room units is arranged to be fitted between two structural decks by transferring the room units to the ship parallel to the structural deck. The formed group of room units may be attached to the underside of the structural cover of a ship or other craft. As already described above, this saves both installation work and material savings on non-enclosed spacer decks.

The advantages of installation work are most evident if the room units of the room unit group are already connected before transfer to the ship, but the essential advantages are achieved even if the room units of room unit group 116049 are arranged separately for ship transfer and arranged in a substantially final location.

From the viewpoint of structural integration, it is advantageous for the plurality of room units 5 to be provided with a horizontal supporting structure such that the said supporting structures together form at least part of the corridor structure and / or deck structure and / or other floor structure associated with the installed room units. The same thing is served by the fact that the room units of the room unit group are provided with a common end wall element, preferably before transfer to 10 vessels. The end wall element is fastened such that it preferably forms part of the outer edge of the vessel or similar craft.

The invention will now be described by way of example with reference to the accompanying drawings, in which: - Figure 1 schematically shows a side unit arrangement according to the invention, - Figure 2 shows a front view of a room unit the ceiling units and floor structures of the room units 20 viewed from the side, - Figure 5 illustrates the use of the lower room units for the upper units. , for transporting room units on board, - Figure 6 illustrates a way of attaching a vertical support structure to room units, and <t · - Figure 7 illustrates, in principle, the installation of an end wall element in a group of 25 room units.

In the drawings, reference numeral 1 denotes a group of room units comprising an upper room unit 2 and a lower room unit 3 which, according to the invention, carry most of the weight of the upper room unit 2. Attachment of the group of room units 1 to the vessel is accomplished by attaching the lower room unit 3 to the ship's structural deck 4 below. The attachment may be in a manner known per se such as welding, screwing, gluing or any other similar method. In this way, it is sufficient that the ship is fitted with a structural deck above the room unit group and below the 5116049, which eliminates the need for a separate intermediate deck. the cabin deck may be omitted from the hull.

Ship systems 5 to be connected to the group of room units 1, which may include e.g.

5 HVAC, fire extinguishing, announcement, monitoring, control, and the like systems are guided at least substantially horizontally between the room unit groups and the superstructure deck 15 of the ship above. In this case, the room unit groups 1 are connected to the ship systems 5 via the upper room unit 2 with separate 10 room unit connections 7. When using a joint connection, the systems of room units 2 and 3 are at least partially interconnected. Alternatively, some ship systems, such as downstream black and / or gray water, may also be directed downward as required, whereby the upper room unit 2 is connected to the drainage system in question via the lower room unit 15 3. In this case, horizontal draws are provided below the group of room units. In any case, most advantageously, the HVAC and / or other systems of room units in a group of room units are already connected to each other before being transferred to the ship.

The room units may be provided with horizontal structural elements 8 which may be supported at one or both ends of the room unit structure, preferably the wall structure 13 of the lower room unit 3 as shown in FIG. 6: Y: illustrated in greater detail. The elements 8 can be provided

corridor structure, deck structure or equivalent floor structure. Alternatively, the corridor or cabin corridor associated with 25 room unit groups may be a ship, ·,; a structural steel deck against which the room unit groups are sealed, or the corridor floor can be installed as a separate light floor module based on the ship's structures and / or room unit group.

Figure 1 thus schematically shows a side view of a group of room units 1 which corresponds to the viewing direction at the end of the ship. Similarly, in FIG. the room unit group 1 is shown from the front, which corresponds to. looking from the side of the ship. In Figure 2, reference numeral 9 indicates the space between two groups of room units in the transverse direction of the vessel. This mode * t 35 can be left open. If the fire prevention regulations require blocking of the space 9, it may be provided with flexible insulation or the 6116049 room units may be overlapped on the ship so that the gap between the room units is covered to form a floor plane 12 as a fire-resistant structure.

Figure 3 shows the service space 10 of the room unit group 1, where most of the connections of the room unit group are moved in the vertical direction of the ship. The electrical box 14 of the room unit may serve two or more vertical room units.

Fig. 4 illustrates a preferred view of a roof and floor structure of a room unit of a group of room units, viewed from the side. In this case, the room units are transferred separately to the vessel and preferably further to the installation site itself. The lower room unit 3 is provided with a roof structure 11 which is a fire insulated structure made of non-combustible material in accordance with the fire regulations of ships 15. In addition, the lower room unit 3 is provided with a floor structure 12 of the upper room unit 2, which is preferably a rigid lightweight structure substantially supported by the wall structure 13 of the lower room unit 3. In this case, 2 overboard the lower room units 3 utilizing the lightweight deck structure formed by the floor structures 12 as illustrated in FIG. 5;

In an alternative solution, the upper room unit is provided with a floor element 12 which can function at least as part of the roof structure 11 of the lower room unit 3.

Figure 7 illustrates in principle a mounting of an end wall element in a room unit group 1, the end wall element preferably being connected to each of the room units. One way is to use the pre-installed end wall element 18, which is thus attached to the room unit group 1 even before it is moved to the ship. Alternatively, the end wall element 19 * 1 35 can be installed from outside the ship after * room unit group 1 is installed and secured so that it
