Floating structures installed in shallow waters can remain mooring to jetty or dolphin. However, this mooring method does not significantly restrain the movement of the floating structure, so if a typhoon occurs, the mooring line must be removed and the floating structure must be evacuated. Recently, as a method for solving such a problem, a mooring method using a file has been proposed.

1 is a perspective view of a floating structure according to an embodiment of the present invention.

Floating structure 100 according to an embodiment of the present invention is mooring the hull 110 using a pile (pile). That is, the floating structure 100 uses pile mooring when mooring the hull 110.

Pile mooring can effectively constrain the movement of the hull 110 by infiltrating the pile into the ground of the seabed and can withstand higher environmental loads than conventional mooring systems. Pile mooring can also reduce installation time and installation costs compared to mooring systems that require the construction of jetty, dolphin and other facilities.

The pile mooring couples the pile and the supporter to restrain the movement of the hull 110. By the way, since the supporter is located on the side of the hull 110, there is a difficulty in installing pile mooring due to interference between the pile and the supporter in the installation step.

Floating structure 110 according to an embodiment of the present invention is characterized in that it has a file support (pile support) structure using a rail (rail) as an interface for solving this.

Referring to FIG. 1, the floating structure 100 according to an embodiment of the present invention includes a hull 110, a rail 120, and a pile interface 130.

Rail 120 is formed on the side of the hull 110, it is formed long downward from the upper side of the hull 110. The file interface 140 is formed to be freely moved in the vertical direction from the side of the hull 110 in combination with the rail 120.

Rail 120 may be formed of a member consisting of a single body. However, the present embodiment is not limited thereto. For example, the rail 120 may be formed of a member having two or more bodies.

The body constituting the rail 120 may be formed in various shapes such as an I-shape and a U-shape. When there are a plurality of bodies constituting the rail 120, each body may be formed in the same shape, but may be formed in different shapes.

At least two rails 120 may be formed on both sides of the hull 110. However, the present embodiment is not limited thereto. That is, the rails 120 may be formed one by one on both sides of the hull 110.

The file interface 130 is coupled to the rail 120 formed on the side of the hull 110. The file interface 130 is formed to be movable on the rail 120.

The file interface 130 may be fitted to the rail 120 according to the structure shown in FIG. 2 so that the file interface 130 may not be easily separated from the rail 120. 2 is a first plan view illustrating a coupling relationship between a rail and a pile interface provided in the floating structure according to an embodiment of the present invention.

Referring to FIG. 2A, the file interface 130 may include two T-shaped arms 132 and 133 protruding from both sides of the body 131 having an empty interior.

When the rail 120 is formed of a U-shaped body having one groove in the front side, the pile interface 130 may be fitted to the rail 120 through the T-shaped arm 134.

As described above, the file interface 130 may include a body 131 having an empty interior. A file is inserted into the empty space of the body 131 to contribute to mooring the hull 110. However, a friction force may occur between the file and the file interface 130 in the process of inserting the file into the empty space of the body 131. In this embodiment, a roller 135 may be provided in the inner space of the body 131 to facilitate the insertion of the file in consideration of this point.

The roller 135 may be formed on each side of the inner surface of the body portion 131. However, the present embodiment is not limited thereto. For example, the roller 135 may be formed over the inner circumference of the body portion 131 or may be formed on both sides of the inner surface facing each other.

In order to fix the movement after the file interface 130 is lowered to a certain point on the rail 120, in this embodiment, the latch 140 is formed on the side of the hull 110. The file interface 130 is provided with an arm for fixing the movement by the latch 140.

Referring to FIG. 2A, two T-shaped arms 132 and 133 are fitted to the rail 120 and are also fixed to the latch 140 at the same time.

Accordingly, in this case, the file interface 130 may include the A-shaped arms 136 and 137 on both sides of the T-shaped protrusion 134. The a-shaped arms 136 and 137 may be formed to face different directions in order to fix the file interface 130 to the latch 140 located in an outward direction from the rail 120.

When the rail 120 is formed as a single body, the file interface 130 may form a coupling relationship with the rail 120 as shown in FIGS. 2A and 2B. When the rail 120 is formed of two bodies, the file interface 130 may form a coupling relationship with the rail 120 as shown in FIG. 3. 3 is a second plan view showing a coupling relationship between a rail and a pile interface provided in the floating structure according to an embodiment of the present invention.

Referring to FIG. 3A, when the rail 120 is formed of two I-shaped bodies 121 and 122, the file interface 130 may have a body portion 131 as in the case of FIG. 2A. ) And two T-shaped arms 132 and 133 may be fastened to the rail 120.

Referring to FIG. 3B, when the rail 120 is formed of two U-shaped bodies 121 and 122, the file interface 130 is fitted to each U-shaped body 121 and 122. Two T-shaped protrusions 134a and 134b may be provided and fastened to the rail 120. The file interface 130 has the a-shaped arms 136 and 137 which are directed in different directions on both sides of the two T-shaped protrusions 134a and 134b even when the file interface 130 is formed as described above. It can be provided.

Meanwhile, the rail 120 may be formed of two c-shaped bodies 121 and 122 oriented in different directions as shown in (c) of FIG. 3. In this case, the file interface 130 may be formed in the structure shown in FIG. 3A and may be fastened to the rail 120.

4 is a front view of the latch provided in the floating structure according to an embodiment of the present invention.

As described above, the latch 140 may be formed at the side of the hull 110. However, in order to firmly fix the hull 110 to the pile, it is preferable to use the plurality of pile interfaces 130 through the rail 120.

The 142b may be formed far from the rail 120. In this case, as shown in FIG. 1, the file interface 130 is preferably formed such that the length of the file interface 130 is longer than the one located below (130a).

In the present invention, in order to minimize interference between the supporter structure and the pile in the installation step, the supporter is not basically located on the ship side. Instead, only the rail 120 is installed on the side of the hull, and when the mooring point is installed, the file interface 130 is lowered through the rail 120 to connect with the file.

The cross section of the rail 120 may vary as shown in FIG. 2, and the file interface 130 is fitted into the groove of the rail 120 to move along the rail 120. And there is an arm (arm) to be fixed across the brace 140 on both ends of the file interface (130).

The latch 140 calculates a position where the file interface 130 is to be installed on both sides of the rail 120 and is installed in advance to the hull 110. The position and the number of the latch 140 may be determined in the design stage through the motion analysis and structural analysis according to the load and environmental conditions of the hull 110.

On the other hand, the file interface 130 is connected to the hull 110 and the pile to restrain the movement of the hull 110 is subjected to a large load. Therefore, in the present embodiment, a structure that directly connects the hull 110 and the file interface 130 and a support structure supporting the same is proposed, instead of relying only on the rail 120.
