In the following description with reference to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, A duplicate description will be omitted.

1 is a view showing an example of a state of using an anchoring apparatus according to an embodiment of the present invention.

Referring to FIG. 1, an anchoring apparatus 100 according to the present embodiment is an apparatus for restricting or fixing the position of an offshore structure or ship 50 floated on the sea, And a mooring line M for transmitting a fixing force or a supporting force by the body portion and the body portion supported in the seabed ground S to the offshore structure or the ship 50 by friction with the material.

As shown in Fig. 1, the anchoring device 100 is free fall into the deep seabed sole S, which is relatively soft, at a predetermined height H from the sea floor. The deeper penetration of the anchoring device 100 into the seabed ground S can increase the resistance to the vertical load or pulling force applied to the anchoring device 100.

The anchoring device 100 can be introduced into the seabed ground S by potential energy having a predetermined height H apart from the seabed surface and as the potential energy of the anchoring device 100 increases, Can be penetrated deeper into the seabed sole (S).

However, the anchoring device 100 receives a resistance force generated by the friction with the seawater during the falling of the water, penetrates the seabed ground S and penetrates the seabed so that the resistance generated by the friction with the surrounding ground Receive. The anchoring device 100 can be penetrated to the target depth by reducing the frictional force caused by different causes in the anchoring device 100 and by increasing the initial potential energy of the anchoring device 100. [

It is possible to increase the drop height of the anchoring device 100 in order to increase the potential energy of the anchoring device 100. This may increase the accuracy of the position where the anchoring device 100 should be intruded, .

One of the other measures for increasing the potential energy is to design the weight of the anchoring device 100 to be large. For example, the anchoring device 100 may be formed of a material having a high specific gravity, or may be filled with a material having a high specific gravity within the anchoring device 100, or a ballast may be inserted into the anchoring device 100 You can fill it in.

Referring to FIG. 1, an anchoring apparatus 100 according to an embodiment of the present invention will be described in detail. First, an anchoring apparatus 100 is mounted on a submarine ground S) to a point spaced apart by a predetermined height (H). That is, the anchoring device 100 is located at the dropping point.

The height H of the anchoring device 100 from the bottom of the seabed so that the descent height of the anchoring device 100 is a function of the magnitude of the vertical load applied to the anchoring device 100 and the accuracy of the penetration depth or penetration point of the anchoring device 100 The design can be changed appropriately according to the tolerance range.

The falling line D and the mooring line M are coupled to the anchoring apparatus 100 descended from the seabed ground S to a predetermined height H. [ The mooring line M is a line connecting the anchoring device 100 penetrated into the seabed ground S and the marine structure or the ship 50 to be installed thereafter. And the drop line D can be constructed in consideration of the required drop height of the anchoring device 100. [0064] As shown in Fig.

When the underwater robot ROV releases the locking device of the connection part between the anchor device 100 and the drop line D, the anchor device 100 can freely fall by its own weight and penetrate the seabed ground S, (S). The mooring line M is connected to the anchoring apparatus 100 penetrated into the seabed ground S and then the mooring line M is connected to the marine structure or the ship 50 to be installed on the sea, It may be fixed or its movement restricted.

2 is a perspective view illustrating an anchoring apparatus according to an embodiment of the present invention. 3 is a view illustrating a state in which the fastening portion is separated from the anchoring device according to the embodiment of the present invention. 4 is a view showing a state where an anchoring apparatus according to an embodiment of the present invention is introduced into a seabed ground. FIG. 5 is a view schematically showing a state in which a first body part and a second body part are deployed to each other through a wedge in an anchoring device according to an embodiment of the present invention.

2 to 5, an anchoring apparatus 100 according to an embodiment of the present invention includes a first body 110, a second body 120, and a fastener 130.

The first body part 110 is a part that can be penetrated into the seabed ground S by a falling method and can be penetrated into the seabed ground S together with the second body part 120 to be described later. Specifically, as described above, if the anchoring device 100 is lowered to a predetermined height H from the seabed ground S and then the falling line D is cut, the first body portion 110 and the second body portion 120 may fall through free fall by its own weight and then be intruded into the seabed ground S.

In this free fall process, as the self weight is increased, the influence of the current or the like can be minimized and the potential energy can be increased relatively. Therefore, the first body portion 110 and the second body portion 120 are dropped together, (S).

The second body part 120 is hinged to one side of the side of the first body part 110 so that one side of the second body part 120 can be penetrated into the bottom of the sea bed S by a falling method together with the first body part 110, 4 and the first body portion 110 as shown in FIG.

It is advantageous to collapse the first body part 110 and the second body part 120 together and to drop and penetrate them in the free fall and intrusion process. However, when considering the resistive force against the pulling force after the penetration into the seabed ground S, 2 When the body portion 120 is spread with respect to the first body portion 110, the resistance against the pulling force can be further increased.

Accordingly, as shown in FIGS. 2 and 3, the first body part 110 and the second body part 120 are folded until reaching the bottom of the sea and penetrating the seabed ground S, The first body part 110 and the second body part 120 can be opened when the rear mooring line M is pulled.

The fastening part 130 is a part that can fasten the other ends of the first body part 110 and the second body part 120 to each other and the first body part 110 and the second body part 120, The other ends of the first and second body parts 110 and 120 are fastened to each other while the first and second body parts 110 and 120 are folded, And may be separated from the other end of each of the body portions 120. [

That is, as shown in FIG. 2, when the first body part 110 and the second body part 120 are in a folded state, the respective surfaces may be symmetrical to each other to have a uniform cross-sectional shape.

Therefore, while the first body portion 110 and the second body portion 120 are falling and penetrated together, the resistance due to the current and ground can be received relatively uniformly in the respective portions of the anchoring device 100, The accuracy of penetration can be further improved.

The first body portion 110 and the second body portion 120 each have a semicircular cross-section. The first body portion 110 and the second body portion 120 have a first side surface and a second side surface, And the second body portion 120 may be unfolded with respect to the first body portion 110 so that the other end is positioned on the same plane.

4 and 5, when the mooring line M is pulled, the first body part 110 and the second body part 120 can function as one plate as a whole, It is possible to further increase the resistance force caused by the friction with the contact surface.

Meanwhile, in the anchoring device 100 according to the present embodiment, the recovery line 130 may be coupled so that the coupling part 130 can be recovered. Only the first body part 110 and the second body part 120 of the anchoring device 100 are penetrated into the seabed ground S and the coupling part 130 includes the first body part 110 and the second body part 120, If it is detached from the second body part 120, the coupling part 130 may be collected and reused by being coupled to another separate first body part and second body part.

As described above, the anchoring device 100 according to the present embodiment can reduce the cost of manufacturing and using the anchoring device 100 by collecting and reusing the fastening part 130. [

In the anchoring apparatus 100 according to the present embodiment, a wedge 150 that can move in the direction of the coupling part 130 may be interposed between the coupling surfaces of the first body part 110 and the second body part 120. That is, as shown in FIG. 5, the wedge 150 may be disposed on a surface of the anchoring device 100 where the first body 110 and the second body 120 are coupled. The wedge may be sharpened toward the direction in which the first body part 110 and the second body part 120 extend, and may be connected to the moire ring line M.

When the mooring line M is pulled, the wedge 150 moves in the direction of the fixed part 130 and the first body part 110 and the second body part 120 are rotated at a predetermined angle The first body 110 and the second body 120 can be completely unfolded as the friction between the first body 110 and the second body 120 progresses. have.
