Description

  The present invention relates to a method of manufacturing a floating structure (e.g., a ship), in which a body of a floating structure is formed, and the body is provided with a deck structure or a corresponding support structure. Also, in the method, a room unit body (room unit) is pre-assembled by providing a main boundary surface body, and the main boundary surface body includes, for example, a plurality of wall and ceiling structures of the room unit body and an internal attachment. At least some of the parts and means (eg, sanitary equipment entry and exit ducts, water pipes, and / or electrical equipment) disposed outside the room unit interface in relation to the internal mounting parts; The main boundary surface body of the room unit body is configured such that a concave service gap is formed outside the room unit body.

The manufacture of floating structures and the manufacture of prefabricated room units and the transportation and installation of the room units on floating structures are already known. Following the installation of the room units, it takes a lot of time and costs to connect the room units to each system of the floating structure via pipes or pipe joints and to connect the room units to each other. A lot of additional work is required. Normally, these operations are performed in a service gap formed outside the room unit body in the floating structure after the room unit body is installed.
Especially in the case of ships (eg ships, oil well drills, etc.), the subsequent work includes welding and other work dealing with dangerous fires in a limited space, in addition to these disadvantages, floating structures There are considerable dangers in the production. The working conditions within the floating structure are also difficult and dangerous for this reason.

  The object of the present invention is to obtain a method in which the disadvantages are eliminated and the pre-assembly stage is as complete as possible and can be carried out cost-effectively.

This object is achieved according to the invention by a method having the features disclosed in claim 1.
The basic idea of the present invention includes a facility or structure in which a pre-assembled room unit that is transported to a floating structure and incorporated in the floating structure is disposed directly around the room unit. The floating structure is manufactured so that the structure forms part of the living system of the floating structure and serves at least the room unit, preferably other room units. In practice, this means that before the room unit is transported and installed in the floating structure, a service gap of the room unit is already provided at the time of preliminary assembly, and the members related to each system of the floating structure are provided in the service gap. Means to equip. In that case, the member to be equipped is not only a member of the room unit body, and the member includes any one or two of a pipe and other medium transport members, a connecting structure connected to them, and an operation and control means. The above is included. Thereby, at least a part of said member is attached to the boundary surface body outside the room unit on the side of the service gap during pre-assembly. In this way, the room unit body that also has parts related to the system of the floating structure is transported to the floating structure and installed in the floating structure, but this is actually the room unit. In connection with the pre-assembly of the body, this means that a significant part of the assembly process of the floating structure must be transferred to a location separate from the floating structure.

The advantage of this configuration is that, firstly, the work of arranging the members in the service gap is performed in a limited space such as the service gap between the room unit bodies when the room unit bodies are installed in the floating structure. Rather, it can be done in open space (in connection with pre-assembly). This solution also eliminates the need to transport large amounts of piping and other equipment separately to the floating structure and move them along a narrow passage to the appropriate location associated with the room unit.
This also makes it possible to place the components in the service gap as functionally as possible, taking into account, for example, the necessary service, repair and adjustment work, and the general accessibility required during use. By doing so, the arrangement of the members becomes constant, in other words, standardized, thereby rationalizing the plan of the floating structure. The amount of parts needed can also be planned more accurately, which will also have a positive impact on timely parts procurement.

In other words, both the installation work of the floating structure itself and the assembly of the floating structure and the supply of parts for the installation work can be optimized by the present invention.
The member connected to the room unit in relation to the pre-assembly is, for example, a floating drainage structure drainage pipe, sewage pipe, clean water pipe, condensed water or discharge pipe, cooling water pipe, fire fighting water pipe, or It is part of two or more members.
In addition, a part of the air conditioning equipment piping and the air conditioning equipment can be arranged in the service gap.

Conventionally, the room unit is arranged as a plurality of layers in the floating structure supported by the deck structure, and in this case, the penetration guide member of the deck structure is preferably attached to the member at the time of preliminary assembly. It is also preferable to provide a flexible connecting means between the member and the penetration guide member of the deck structure. The penetration guide member of the deck structure attached in advance is thus transported to the floating structure together with the room unit, thereby making use of the space provided by the flexible connecting means to make room for multiple layers. The deck structure can be easily attached between the unit bodies. For this reason, the finishing work to be performed on the floating structure mainly consists of a joining work between a plurality of layers or a plurality of deck structures.
The invention also relates to a method for making a prefabricated room unit according to claim 2. Preferred embodiments are described in claims 10 to 14.

In the following, embodiments of the present invention will be described in more detail with reference to the accompanying schematic drawings. The embodiment is only an example.
In FIG. 1, a floating structure is denoted by reference numeral 1. The floating structure including the trunk 100 has a deck structure or a corresponding support structure 2 on which a number of preassembled at least partially equipped room units 3 are arranged. Yes. The room unit 3 is arranged on both the lower part 102 and the upper part 103 of the trunk part 100 of the floating structure 1. In the figure, how the means related to the mounting parts of the room unit body and the members related to the system 5 of the floating structure are arranged outside the boundary surface body 4 of the room unit body 3, Simplified by a broken line. These arrangements according to the invention will be described in more detail later.
The floating structure may be, for example, a ship, such as a ship, an oil well drilling device, or other corresponding structure. Accordingly, the subject matter relating to the embodiments described below also applies to the floating structure as a whole.

In the following description of one embodiment of the present invention, the floating structure will be referred to as ship 1 for clarity. Therefore, the room unit body is referred to as the cabin 3 and the boundary surface body is referred to as the wall portion 4. In FIG. 1, the cabin 3 is below the so-called open deck 2 of the ship, at the bottom 101 of the torso 100, that is, actually the hull part of the ship, and above the open deck 102 of the ship, ie above the ship's hull part 103. And both.
As a result, the wall structure of the cabin structure, which will be described in detail later, can be formed simultaneously with the formation of the ship skin or each part of the ship. For example, in a passenger ship having an inboard promenade with a series of cabins, the wall structure of the cabin structure accordingly forms the inside of the ship or each part of the ship.

A recess-shaped service gap 10 is provided outside the cabin 3. For example, if the basic shape of the cabin is rectangular, a recess recessed inward of the cabin can be formed in one corner of the rectangle, and the shape of the recess is selected based on the mounting parts of the cabin or other functional reasons . Examples of these service gaps are shown in FIGS.
In the case of FIG. 2, the cabin 3 is arranged on the two deck structures 2 . A part of the pipe 6 is fixed to the wall 4 of the cabin 3 (not shown), and each part can give a clearance to each other and to the ship system 5 and the first flexible connecting means, for example during installation. They are connected via flexible tubes or hoses. It's an example of a member that is not connected directly to the prefabricated cabin 3, these parts materials, before the ship chamber is conveyed to the ship, it may be attached to the cabin during the pre-assembled. These members include, for example, miscellaneous drainage pipes, sewage pipes, clean water pipes, condensed water or drainage pipes, cooling water pipes, and fire extinguishing pipes.

FIG. 3 shows a configuration corresponding to the configuration of FIG. In this case, the 1st piping part 61 is attached to the wall part 4 of each cabin 3 via the fixing means 9, for example, the pipe clamp etc. which were fixed to the wall part 4 by the arm. This fixing can also be performed directly on the wall by means of a fixing strap. The 1st piping part 61, for example, the miscellaneous drainage piping and sewage piping related to the internal attachment components of the cabin, for example, are members connected to two or more cabins. The first piping part 61 is connected to the cabin 3 or rather can be connected to the entry and exit ducts arranged in the cabin via, for example, flexible coupling means or a conventional pipe section 8.
The first piping portion 61 is connected to the ship system 5 via the flexible second connecting means 71. The first piping sections 61 added to the overlapped cabin 3 of FIG. 3 are interconnected in two different ways. In the configuration on the left side, the connection is made via the flexible third connection means 72, and in the configuration on the right side, the connection is made using a combination of the flexible third connection means 72 and the connection pipe 63. In relation to the deck structure 2, the deck structure penetration guide member 13 can also be used. The penetration guide member will be described with reference to FIG.

The flexible coupling means can of course be replaced by conventional tube parts or tube segments and vice versa.
4 and 5, a common service gap 10 is provided between the two cabins 3. The first means 11 (FIG. 4) related to the cabin equipment is installed outside the wall portion 4 of the one cabin 3 (left side in the figure). The second means 12, for example, an electric junction box is installed outside the wall portion 4 of the other cabin 3 (right side in the figure). Members related to the ship system 5, for example, the first piping portion 61 and the second piping portion 62 are also arranged in the service gap 10, and both of them are fixed to the wall portion 4 of the left cabin 3 by the fixing means 9. Is done.

In Figure 5, the first pipe portion 61, via a flexible coupling means 14 (e.g., flexible tube or hose giving clearance for installation), attached to the bushing member 13 disposed in the deck structure 2 It has been. The penetration guide member 13 of the deck structure may be already attached to the first piping portion 61 at the time of preliminary assembly. By doing so, it can be transported to the ship with the prefabricated cabin assembly.
FIG. 6 shows another configuration of the cabin 3. In this case, the cabin 3 has a configuration for each chamber, and for this reason, a dedicated service gap 10 is provided in each cabin. The service gap 10 includes the first piping portion 61 and the second piping portion 62 related to the water pipe 11 and the electrical equipment box 12 related to the mounting parts of the cabin 3, as in the ship system 5. In addition, the air conditioning equipment 15 is arranged in the service gap.
In known systems, the air conditioning equipment is usually installed in the cabin 3, so that the space available in the cabin is narrowed, and the comfort of the cabin user is also reduced.

This figure shows how the practical means and the control means are functionally arranged in the service gap in addition to the various means, members, and connecting structures described above. Since the electrical equipment 12 is disposed at the top of the pipe portions 61 and 62, it can be easily approached. Therefore, the air conditioning equipment 15 is installed on the wall facing the electrical equipment box 12 in the same service gap. The air conditioning equipment can alternatively be arranged between the piping part and the electrical equipment box.
Needless to say, there are many possible solutions for the arrangement, so that in each case the most functional arrangement can be selected, taking into account the necessary service, repair and usage measures, for example.
Another factor affecting this point is, of course, the placement of service gaps. For example, the cabin shown in FIG. 4 is arranged symmetrically with each other, so that a wider service gap common to the two cabins is formed. The cabin 3 shown in FIG. 6 is a sequentially arranged cabin having a similar shape, but in this case, each cabin is provided with a separate, smaller service gap.

In conjunction with the cabin pre-assembly, a well-designed service gap can include other spaces as well, such as space for temporary storage.
The horizontal dimension of the means and members added to the cabin service gap in connection with the pre-assembly is preferably limited to the width of the service gap, the vertical dimension being the height of the service gap, i.e. the cabin height. In addition, or at least, it is preferably limited to the height between deck structures or between other corresponding support structures.
The cabins can also be transported as a group, for example, two to the ship, in which case there is no actual deck structure between the cabins. Therefore, the dimension in the vertical direction will be limited depending on the height between cabins.
In practice, the height between the ship deck structures is for example 2700 mm, in which case approximately 2200 mm of prefabricated piping is carried along with the two cabins. This is very important for finishing work on board.

The method according to the present invention includes the following operations.
The ship, or indeed the hull part thereof, is partly or wholly assembled in a manner known per se.
The cabin is often assembled with at least walls and ceiling structures in the factory environment, in which case doors, windows, and balcony structures can be added if necessary. The wall is configured such that a concave service gap is formed in the cabin.
Thereafter, the interior of the cabin is equipped as desired and the necessary external connections are made through the wall of the service gap. Then, various means relating to the (above) cabin and other members mainly relating to the ship's habitat, at least members of the cabin, preferably also serving other cabins, are placed in the service gap. Since these means and components are arranged to be suitable for subsequent use, the necessary accessibility is ensured and sufficient clearance for service and repair work is left in the service gap.

The means and members are arranged so as not to protrude out of the boundary of the cabin or service gap. The penetration guide member of the deck structure used with the piping can be installed separately in the ship later or easily attached to the piping so as to be transported together with the cabin.
At this stage, the prefabricated cabin assembly can be carried to the ship. The remaining work on board is simply connecting the means and components to the relevant parts of the ship's habitat. For example, connection to the pipe, by using a flexible hose and sliding coupling member, only by using a small tool, it is carried out very easily without performing a treatment involving welding other correspondingly dangerous it can.
In this way, the finishing work done on board is reduced and the work done in connection with the finishing of the prefabricated cabin is completed more quickly within a reasonably structured service gap.
The above description and related drawings are only intended to clarify the basic idea of the present invention. The details of the invention may vary within the scope of the claims.
