Abstract

PURPOSE:To prevent the contact of a floating type structure with other structures by restricting the lateral movement of floating type structures by a method in which mooring ropes connected to the side far away from the adjacent floating structures are bundled into one rope, and a sinker and an anchor block are attached to the tip of the rope for mooring. CONSTITUTION:Floating type structures 1, e.g., floating breakwater, etc., are set vertically in a row, holes 2 are provided in the right and left both ends of each structure 1, and brackets 3 are provided to the upsides of the holes 2. One ends of mooring ropes 5, e.g., chain, rope, etc., attached with intermediate weights 4 are passed through the holes 2 and connected to the brackets 3. The other ends of mooring ropes 5 connected to the side far away from the adjacent floating type structures 1 are bundled into one rope, and sinkers 6 and anchor blocks 7 are attached to the ropes for mooring. The lateral movement of the floating type structures 1 when receiving waves in the right-angled direction can thus be restricted to prevent damage to the structures 1 by mutual contact.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for mooring a floating structure.

[Conventional technology]

In aquaculture farms, ports, yacht harbors, etc., floating structures (as shown in Figure 8) are installed for the purpose of wave dissipation or wave prevention.
1) are arranged vertically in the direction (X direction) perpendicular to the wave direction (Y direction) to be dissipated or blocked, and each of the floating structures Both sides of (1) are moored to anchor blocks (7) via mooring ropes (5) to which intermediate weights (4) and sinkers (6) are attached.

[Problem that the invention seeks to solve]

However, in the above mooring method, the wave direction (
However, if diagonal waves other than the Y direction or waves in the X direction are larger than expected, the adjacent floating structure (1) will move as shown in Figure 11. , there is a concern that it will get upset and come into contact with it, causing damage. In addition, wave dissipation and wave prevention functions will be impaired.

Also, since one floating structure (]) is moored with four independent mooring ropes (5), a large number of mooring materials are required, such as four sinkers (6) and anchor blocks (four each), which is inconvenient. Not only was it economical, but mooring work was also time-consuming.

Furthermore, as shown in FIG. 12, brackets (8) are provided on both sides of the floating structure (1), and the mooring cables (5) are connected to the brackets (8). (1)
Since there are mooring lines (5) in the sea beside the floating structure (1), there is a high probability of contact between the floating structure (1) and the ship9, which is unfavorable from a safety point of view. Furthermore, as the navigation range of ships becomes narrower, mooring work and maintenance inspections of floating objects are strictly prohibited.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention moors mooring cables connected to adjacent floating structures of a plurality of floating structures arranged in a column to a common anchor block, and
The mooring lines connected to the floating structures at both ends were moored to separate anchor blocks.

[For production]

As a result, both ends of multiple floating structures arranged in a column are moored to separate anchors via mooring lines pulled on both sides, and adjacent floating structures are moored by mooring lines using a common anchor block. Since the floating structure is moored through the floating structure, even if diagonal waves or waves from the X direction become strong, contact and damage to adjacent floating structures can be prevented. Because a common anchor and sinker are used, less mooring materials are required.

〔Example〕

1 to 6 show a first embodiment of the present invention, in which a plurality of floating structures (1) are arranged in a vertical line in a direction perpendicular to the wave-dissipating or wave-blocking (Y direction) (this embodiment (3 pieces) and mooring cable passage holes (2) at both left and right ends of each floating structure (1).
A bracket (3) is provided on the upper surface of the floating structure (1) near the mooring cable passage hole (2).

One end of a mooring cable (5) such as a chain or rope with an intermediate weight (4) attached is inserted into each mooring cable passage hole (2) from the bottom side, and each mooring cable (5) is inserted into each of the brackets (3).
).

Floating structure (1) in the center of floating structures (1) at both ends
A sinker (6) made of concrete, Ikari, etc. and an anchor block (7) made of concrete, Ikari, etc. are attached to the other end of the side mooring cable (5), and floating structures (1) at both ends are attached.
) is submerged and moored on the seabed on both sides of the rear side of the O.In addition, each mooring line (5) connected to the remote side of each adjacent floating structure (1) is combined into one line, and a sinker (6) is attached.
And anchor blocks (7) are attached and moored by sinking into the seabed on both sides between each floating structure (1).

Since it is moored as described above, even if diagonal waves other than the Y direction or waves in the X direction become large, each floating structure (]) will be interconnected and pulled from both ends, so the floating The oscillation of the structure (1) is stopped and movement is restricted.

4 and 5 show a second embodiment of the present invention, which is an example in which the left and right mooring ropes (5) are crossed in substantially the same configuration as the first embodiment.

In the case of this embodiment as well, the movement of the floating structure (1) can be restrained not only in the Y direction but also against oblique waves and waves in the X direction, as described above.

FIGS. 6 and 7 show a third embodiment of the present invention, in which mooring cables (5) at both ends are arranged in substantially the same configuration as the first embodiment.
This is an example in which the mooring cables (5) at the adjacent positions of the floating structure (1) are arranged in one line.

In the case of this embodiment as well, the movement of the floating structure (1) can be restrained against oblique waves and waves in the X direction.

It should be noted that the present invention is not limited to the above-described embodiments, and that any number of floating structures may be connected as long as it is two or more, and that the present invention can be used for main mooring of plants, purges, artificial islands, etc.
Of course, various modifications can be made without departing from the gist of the present invention, such as being able to be used for temporary mooring.

〔Effect of the invention〕

As described above, the method for mooring a floating structure of the present invention exhibits various excellent effects as described below.

(1) The mooring cables, which were conventionally arranged in parallel, are crossed, and the mooring cables of adjacent floating structures are moored together at one end, which stops the floating body from moving. It is possible to restrict movement when receiving diagonal waves or waves in the X direction.

(n) With (I), floating structures will not come into contact with each other and will not be damaged, eliminating concerns about damage.

(1) Since multiple anchoring objects such as anchor blocks and sinkers can be reduced to one size, less mooring materials are required than with conventional mooring methods, and the mooring work is also faster, making it very economical. .

(IV) The installation of the mooring cables has been changed from the side of the floating structure to the inside of the top of the floating structure, increasing the navigation range of the vessel and making it easier to come alongside the floating structure.
This makes anchoring work and maintenance inspections easier.
