Description

Floating marine structure and floating marine power generation device having the same {FLOATING OFFSHORE STRUCTURES AND FLOATING OFFSHORE POWER PLANT HAVING THE SAME}

The present invention relates to a floating marine structure and a floating marine power generation device equipped with the same.

As problems such as environmental regulations due to global warming and instability in the supply and demand of fossil fuels emerge, wind power generation, one of the new and renewable energy production systems, is receiving attention.

A wind power generation device is a device installed on land or in the sea that converts wind energy into electrical energy and produces electricity.

Wind power generation devices have been mainly installed on land, but offshore installations are gradually increasing. For wind power generation, the quality of wind at sea is generally better than on land, and there is an advantage in that it is easier to respond to blade noise problems. In particular, in order to secure economic feasibility, it is necessary to secure a large-scale complex, but it is difficult to secure such a complex on land, so coastal and offshore areas are emerging as large-scale offshore wind farms.

Structures for installing wind power generation devices at sea can be broadly divided into fixed and floating types. A fixed structure is a type in which the structure is directly fixed to the seafloor, like on land, and responds to environmental loads through structural deformation. A floating structure floats on the water and is subject to self-weight, buoyancy, environmental load and mooring force, and the movement and mooring of the structure. It is a method of overcoming environmental loads through force.

Until recently, offshore wind power plants were fixed and mainly installed in shallow water. However, fixed structures provide advantageous power generation conditions because the structure is fixed to the seafloor, but as the depth of water deepens, the size of the structure becomes too large and it becomes difficult to avoid the risk of fatigue failure. Additionally, as wind power generation devices become larger, the cost of manufacturing and installing structures increases astronomically.

In addition, the wind becomes stronger and more consistent the further it is from land, which can increase power generation efficiency. Accordingly, the need for the development of wind power generation is gradually increasing, even in deep waters far from the coast. Therefore, much research is being conducted on offshore wind power generation devices using floating structures that are not limited by the size of the structure even as the water depth increases.

The present invention was created to improve the conventional technology, and one purpose of the present invention is to provide a floating marine structure that can be installed regardless of water depth and a floating marine power generation device equipped with the same.

A floating marine structure according to one aspect of the present invention includes a plurality of columns; and a plurality of protruding members installed at the bottom of each of the columns, wherein a polygonal shape is formed by an imaginary line connecting the columns, and the protruding members have a cross-sectional area larger than that of the columns, At the bottom of the columns, the polygonal shape has a shape that protrudes at least inward among the inner and outer sides.
Specifically, the protruding members have a shape that protrudes inward and outward of the polygonal shape at the bottom of the columns, the length of the protruding members protruding outward is smaller than the length of the protruding inward, and the protruding members are The length protruding outward may be less than or equal to the thickness of the fender used when docking the inner walls of the columns.
Specifically, a center column disposed inside the polygonal shape formed by the columns and supporting a power generation structure provided on the top; And it may further include a main pontoon installed at the bottom of the center column.
Specifically, it may further include a plurality of braces, where some of the braces may connect each of the protruding members, and others of the braces may connect the protruding members and the main pontoon.
Specifically, the protruding members may have an arc shape in an area adjacent to the center column.
Specifically, the columns may have a circular or polygonal cross-section parallel to the sea level.

That is, the power generation structure (PGS) may be installed eccentrically on one side of the floating offshore structure (FOS).

The sickle cell (NC) may be installed on the top of the tower (TW). The sickle cell (NC) can produce electricity from the rotational force of the blade (BL).

Meanwhile, in this embodiment, it has been described as an example that the power generation structure (PGS) is installed eccentrically on one side of the floating offshore structure (FOS), but it may not be limited thereto. For example, the power generation structure may be installed at the center of a floating offshore structure (FOS).

The plurality of columns 110, 120, and 130 may support superstructures, for example, a power generation structure (PGS). The floating offshore structure (FOS) may have a polygonal shape due to virtual lines connecting the plurality of columns 110, 120, and 130. That is, the columns 110, 120, and 130 may be arranged at vertices of a polygonal shape.

The plurality of columns 110, 120, and 130 may include first to third columns 110, 120, and 130. Meanwhile, in this embodiment, it has been described as an example that the floating offshore structure (FOS) includes three columns 110, 120, and 130, but it is not limited thereto. For example, a floating offshore structure (FOS) may include four or more columns.

The cross sections parallel to the sea level of the first to third columns 110, 120, and 130 have a polygonal shape, and the first to third columns 110, 120, and 130 may have the same cross section or different cross sections. You can. For example, the cross section of the first column 110 parallel to sea level may have a hexagonal shape in which the area adjacent to the two opposing vertices of the rectangle is chamfered. Here, the chamfered area of the first column 110 may be disposed toward the outside of the floating offshore structure (FOS). The chamfered area of the first column 110 may be arranged to face the outside of the polygonal shape formed by the plurality of columns 110, 120, and 130.

Additionally, cross sections of the second column 120 and the third column 130 parallel to the sea level may have a rectangular shape. The cross-sectional area parallel to sea level of the first column 110 may be larger than the cross-sectional area parallel to sea level of each of the second column 120 and the third column 130.

Meanwhile, in this embodiment, it has been described as an example that the cross-sections parallel to the sea level of the first to third columns 110, 120, and 130 have a polygonal shape, but it is not limited thereto. For example, the cross-section parallel to the sea level of the first to third columns 110, 120, and 130 is straight at the portion in contact with the plurality of pontoons 210, 220, and 230, and the other areas are curved.

In addition, the cross-section parallel to the sea level of the first to third columns 110, 120, and 130 has a shape in which a portion of a circle is cut straight, and pontoons 210, 220, and 230 are installed in the cut area. It can be.

The plurality of pontoons 210, 220, and 230 may include first to third pontoons 210, 220, and 230. The first to third pontoons 210, 220, and 230 may be installed at the bottom of the first to third columns 110, 120, and 130. Here, the first to third pontoons 210, 220, and 230 may be installed inside the polygonal shape formed by the first to third columns 110, 120, and 130.

Additionally, the size of the first pontoon 210 may be larger than the sizes of the second pontoon 220 and the third pontoon 230. Accordingly, the buoyancy provided by the first pontoon 210 may be greater than the buoyancy provided by each of the second pontoon 220 and the third pontoon 230.

Cross sections of the first to third pontoons 210, 220, and 230 parallel to the sea level have a polygonal shape and may have the same cross section or different cross sections. For example, a cross section parallel to the sea level of the first pontoon 210 may have a hexagonal shape in which the area adjacent to the two vertices of a rectangle disposed spaced apart from the first column 110 is chamfered. In addition, the cross sections of the second pontoon 220 and the third pontoon 230 have at least one corner of the two rectangular vertices arranged to be spaced apart from the second column 120 and the third column 130 having a rectangular chamfered shape.

The second upper brace 320 may connect the top of the first column 110 and the top of the third column 130. The third upper brace 330 may connect the first upper brace 310 and the second upper brace 320. Here, the third upper brace 330 may connect areas adjacent to the second column 120 and the third column 130 of the first upper brace 310 and the second upper brace 320.

The lower braces 340, 350, and 360 include a first lower brace 340 connecting the first pontoon 210 and the second pontoon 220, and the first pontoon 210 and the third pontoon 230. It may include a second lower brace 350 connecting the lower portions of the second column 120 and the third column 130 and a third lower brace 360 connecting the lower portions of the second column 120 and the third column 130. The third lower brace 360 may be connected to the first lower brace 340 and the second lower brace 350.

The length of the first lower brace 340 may be shorter than the length of the first upper brace 310. This means that the first upper brace 310 connects the upper parts of the first column 110 and the second column 120, but the first lower brace 340 connects the first pontoon 210 and the second pontoon 220. Because it connects.

The length of the second lower brace 350 may be shorter than the length of the second upper brace 320. This means that the second upper brace 320 connects the upper parts of the first column 110 and the third column 130, but the second lower brace 350 connects the first pontoon 210 and the third pontoon 230. Because it connects.

The length of the third lower brace 360 may be greater than the length of the third upper brace 330. This means that the third upper brace 360 connects the areas adjacent to the second column 120 and the third column 130 of the first upper brace 310 and the second upper brace 320, but the third lower brace ( This is because 360 connects the lower part of the second column 120 and the lower part of the third column 130.

Meanwhile, a tower of a power generation structure (PGS) may be installed on the first column 110. That is, the power generation structure (PGS) may be installed eccentrically on one side of the floating offshore structure (FOS). This is because the cross-sectional area of the first column 110 is the largest, so that sufficient installation space for the power generation structure (PGS) can be secured. In addition, since the buoyancy of the first pontoon 210 installed on the first column 110 is the highest, the stability of the power generation structure (PGS) is improved even if the power generation structure (PGS) is installed on the first column 110. Because you can do it.

Meanwhile, in this embodiment, it has been described as an example that the power generation structure (PGS) is installed on the first column 110 of the floating offshore structure (FOS), but it may not be limited thereto. For example, the power generation structure may be installed at the center of a floating offshore structure (FOS).

In the floating offshore structure (FOS) as described above, the first to third pontoons (210, 220, 230) are installed on the inner surface of the bottom of the first to third columns (110, 120, 130). You can. Therefore, it can be advantageous for docking at the quay wall of a ship for installing or maintaining floating offshore structures (FOS) and power generation structures (PGS).

In addition, since the length of each of the first lower brace 340 and the second lower brace 350 is shorter than the length of each of the first upper brace 310 and the second upper brace 320, the floating offshore structure (FOS) The structural stability of can be improved.

The pontoon 200 can provide buoyancy to a floating offshore structure (FOS). Pontoon 200 may be installed on one side of the bottom of column 100.

A cross section of the pontoon 200 parallel to the sea level may have a polygonal shape. For example, a cross section of the pontoon 200 parallel to the sea level may have a shape in which the area adjacent to the two vertices of a rectangle disposed apart from the column 100 is chamfered.

The pontoon 200 may include a hollow portion (HP), and the hollow portion (HP) is formed in a direction perpendicular to the sea surface to prevent damage to the column 100 due to waves, etc. Additionally, a porous damper (DP) may be disposed in the hollow portion (HP). The damper DP may include at least one porous plate DP1, DP2, and DP3 having a plurality of through holes TH. For example, the damper DP may include first to third porous plates DP1, DP2, and DP3.

Dampers (DP) can help dissipate energy in floating offshore structures (FOS). Accordingly, the damper DP can reduce the vertical movement of the floating offshore structure (FOS).

Meanwhile, the through holes TH of the porous plates DP1, DP2, and DP3 adjacent to each other may not overlap. For example, the through holes TH of the first porous plate DP1 and the second porous plate DP2 may not overlap each other. Additionally, the through holes TH of the second porous plate DP2 and the third porous plate DP3 may not overlap each other on a plane. Additionally, the through holes TH of the first porous plate DP1 and the third porous plate DP3 may overlap each other on a plane.

Additionally, the through holes TH of the adjacent porous plates DP1, DP2, and DP3 may overlap. For example, the through holes TH of the first to third porous plates DP1, DP2, and DP3 may overlap each other on a plane.

The plurality of columns 110, 120, and 130 may support superstructures, for example, a power generation structure (PGS). The floating offshore structure (FOS) may have a polygonal shape due to virtual lines connecting the plurality of columns 110, 120, and 130.

Below, the location of the center column (CC) will be described in more detail.

When the floating offshore structure (FOS) docks at the quay wall (QW), two of the first to third columns 160, 170, and 180 may be provided adjacent to the quay wall (QW). For example, the first and third columns 160 and 180 may be disposed adjacent to the quay wall QW, and the second column 170 may be disposed spaced apart from the quay wall QW.

The length of the first upper brace 310 and the first lower brace 340 connecting the first column 160 and the tower support column (TSC) is equal to the length of the second and third columns 170 and 180 and the tower support column ( It may be shorter than the length of the second and third upper braces 320 and 330 and the second and third lower braces 350 and 360 that connect the TSC).

Accordingly, the tower support column (TSC) may be deflected from the center of the triangle formed by the first to third columns 160, 170, and 180 in a direction adjacent to the first column 160.

That is, the tower support column (TSC) may be deflected adjacent to the quay wall (QW) at the center of the triangle formed by the first to third columns (160, 170, and 180).

As described above, if the tower support column (TSC) is biased toward the quay wall, the distance between the quay wall (QW) and the power generation structure (PGS) may be reduced. Therefore, it can be easy to operate equipment such as a crane installed adjacent to the quay wall (QW).

In addition to the embodiments described above, the present invention may encompass all embodiments resulting from a combination of at least two or more of the above embodiments or a combination of at least one of the above embodiments and known techniques.

Although the present invention has been described in detail through specific examples, this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and can be understood by those skilled in the art within the technical spirit of the present invention. It would be clear that modifications and improvements are possible.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
