Description

[Technical Field]

[0001] The present invention relates to a method for manufacturing a floating structure. [Background technology]

[0002] BACKGROUND ART Conventionally, floating structures such as ships are manufactured in a shipbuilding dock and launched by injecting water into the dock (see Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-179757 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the manufacturing method described in Patent Document 1 has the problem that it is difficult to manufacture the next floating structure at the shipbuilding dock until one floating structure has been manufactured and launched, making it unsuitable for mass production.

[0005] Therefore, the present invention has been made in consideration of the above circumstances, and provides a method for manufacturing a floating structure that can be mass-produced. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention employs the following means. In other words, the method for manufacturing a floating structure according to the present invention is a method for manufacturing a floating structure in which a floating structure capable of generating at least buoyancy is manufactured at a work site on land, and the floating structure is launched into a body of water, and a lift is used, which is provided in a location adjacent to the work site in the body of water, and which has a mounting section on which the floating structure can be placed, which can be exposed above the water surface or positioned underwater, and the floating structure is launched by changing the mounting section of the lift from a state exposed above the water surface to a state positioned underwater, making it possible to manufacture another floating structure at the work site.

[0007] In the manufacturing method of a floating structure configured as described above, the launching of a floating structure by a lift and the manufacturing of another floating structure in a workshop can be carried out simultaneously, which allows the manufacturing of floating structures to proceed smoothly and quickly, and enables mass production.

[0008] In addition, the method for manufacturing a floating structure according to the present invention may be such that a groove is provided in the work area and the storage section to enable the floating structure to be moved from the work area to the storage section of the lift.

[0009] In the manufacturing method for a floating structure configured in this manner, the floating structure can be moved along a groove that connects the work area to the lift's mounting portion, thereby improving workability.

[0010] In addition, the method for manufacturing a floating structure according to the present invention may be such that a belt conveyor is provided in the work area and the storage area to enable the floating structure to be moved from the work area to the storage area of ​​the lift.

[0011] In the manufacturing method of a floating structure configured in this manner, the floating structure can be moved on a belt conveyor that connects the work area to the loading section of the lift, thereby improving workability. [Effects of the Invention]

[0012] The method for manufacturing a floating structure according to the present invention allows for mass production. [Brief explanation of the drawings]

[0013] [Figure 1] 1 is a schematic diagram illustrating a manufacturing method of a floating structure according to one embodiment of the present invention. FIG. [Figure 2] FIG. 2 is a schematic diagram showing the configuration of a lift. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, a method for manufacturing a floating structure according to one embodiment of the present invention will be described with reference to the drawings. First, we will explain the facilities used when manufacturing the floating structure 1. The facilities for manufacturing the floating structure 1 include a work area 31 consisting of land such as a quay, and a water area W adjacent to the work area 31. Although not shown in Fig. 1, the work area 31 may include a building such as a factory, and is an area for forming the floating structure 1 assembled so as to have at least a configuration capable of generating buoyancy.

[0015] The water area W is an ocean, a lake, or the like, and is an area where the floating structure 1 can be launched. A lift 2 that enables the floating structure 1 to be launched is provided in the water area W. FIG. 2 is a schematic diagram showing the configuration of the lift 2. As shown in FIG. 2, the lift 2 has a lift base (support portion) 23 on which the floating structure 1 can be placed, multiple piles 21, a center-hole jack 22, and a rod 22a. The multiple piles 21 extend vertically, have the center-hole jack 22 fixed to their upper ends, and are installed on the seabed by being driven into the seabed G of the water area W. One end of the rod 22a is fixed to the lift base 23, and the other end is inserted through the center-hole jack 22. In this way, the lift base 23 is configured to be able to assume two states: a state in which the rod 22a is exposed above the water surface of the water area W when the center-hole jack 22 pulls the rod 22a; and a state in which the center-hole jack 22 allows the rod 22a to move and is located underwater in the water area W. In other words, the center-hole jack 22 uses the reaction force of the piles 21 to move the lift base 23 up and down. The lift base plate 23 moves downward and into the water, so that the floating structure 1 placed on the lift base plate 23 can be launched.

[0016] The floating structure 1 may be moved from the work site 31 to the lift base 23 of the lift 2 using various methods. For example, a method of placing the floating structure 1 on a mounting platform equipped with a vertically moving jack and a horizontally moving jack and sliding it (IP-CCV system) may be used. Alternatively, a method of placing the floating structure 1 on a mounting platform equipped with air casters and moving it using a jack or winch, or a method of moving the mounting platform with the floating structure 1 on it using a belt conveyor, or a method of attaching tracks, wheels, or the like to the mounting platform may be used. It is preferable that the path from the manufacturing site of the work site 31 to the lift 2 and the lift base 23 of the lift 2 be provided with rails or grooves on which the IP-CCV system, air casters, tracks, or wheels can run, or that a device such as a belt conveyor is attached, so that the above-mentioned moving devices can be utilized.

[0017] Next, a method for manufacturing a floating structure according to one embodiment of the present invention will be described. As shown in FIG. 1, at least the components of a floating structure 1 that are capable of generating buoyancy are manufactured in a workshop 31. The floating structure 1, which has at least the components that are capable of generating buoyancy and which has been manufactured in the workshop 31, is moved onto a lift base plate 23 that is exposed above the water surface of a lift 2 installed in a water area W. Then, the lift base plate 23 of the lift 2 is lowered, and the lift base plate 23 is changed from a state where it is exposed above the water surface to a state where it is located underwater, thereby launching the floating structure 1 into the water area W. While the floating structure 1 is being launched into the water area W, the workshop 31 starts manufacturing a new floating structure 1. By repeating the above operations, floating structures 1 are manufactured one after another.

[0018] In the manufacturing method of a floating structure configured in this manner, the launching work of the floating structure 1 by the lift 2 and the manufacturing work of another floating structure 1 in the workshop 31 can be carried out simultaneously. This allows the manufacturing of the floating structure 1 to proceed smoothly and quickly, enabling mass production.

[0019] In addition, the floating structure 1 can be moved along a groove connecting the work area 31 to the lift base plate 23, or on a belt conveyor connecting the work area 31 to the lift base plate 23, thereby improving workability.

[0020] Furthermore, when launching using the lift 2, the floating structure 1 is not suspended, so there is no need to reinforce the floating structure 1, which eliminates the need for reinforcement work and allows for manufacturing in a short period of time, as well as mass production at low cost.

[0021] The assembly procedures, shapes and combinations of the components, etc. shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements, etc., within the scope of the present invention. [Explanation of symbols]
