Description

Technical Field [0001] The present invention relates to a suction foundation assembly, a suction foundation construction method, and a marine wind power generation facility using the same,

The present invention relates to a suction foundation, a suction foundation assembly, a suction foundation construction method, and an offshore wind power generation facility using the same. More particularly, the present invention relates to a suction foundation, A suction foundation assembly, a suction foundation construction method, and an offshore wind power generation facility that is easily leveled using the same.

The foundation of the marine uses mono files, suction bases, gravity bases and jacket bases. Suction Pile is a file installed by using the pressure difference between the inside and outside of the file generated by discharging the fluid such as water or air inside the file to the outside. It is used in submarine floors and is used for marine fixed and floating structure supports or anchors, such as oil drilling platforms, offshore wind power bases. Fig. 1 is a photograph of a conventional suction foundation, and Fig. 2 is a conceptual view showing a penetration state of a conventional suction foundation as a longitudinal section. As shown in Figs. 1 and 2, the shape of the suction foundation 1 has a shape in which the upper end is closed by the upper plate and the lower end of the cup is opened so that suction pressure can be easily applied. The largest of the foundations (1) constructed to date is 32m in diameter and 37m in length, and is constructed on a 300m deep sea floor and used as the basis for oil drilling platforms. At this time, the suction foundation 1 may be provided with a discharge port and an injection port on the top plate or side surface of the upper part for discharging and injecting seawater, and a ring for use as a point of application in drawing can be provided at the center or side of the upper part.

As shown in Fig. 2, the installation mechanism of the suction foundation 1 is as follows. When the suction foundation 1 is seated on the seabed layer 40, the lower end of the file is penetrated to the depth of the seabed layer 40 to a certain depth by the self weight of the file. In this state, seawater in the suction foundation (1) is drained to the outside by using a drainage device installed on the head of the suction foundation (1). Since the structure of the suction foundation 1 except for the lower end of the pile is completely blocked by the flow of seawater, the drained sea water can flow only through the seabed layer 40 at the lower end of the suction foundation 1. However, since the permeability of the seabed ground is very low, the drainage water is prevented from being introduced and recovered, so that the pressure inside the suction foundation 1 is lower than the pressure outside the suction foundation 1. As a result, a pressure difference between the inside and the outside of the suction foundation 1 is generated, thereby causing the suction foundation 1 to be intruded.

(2) It can be installed regardless of the size of the suction foundation. The larger the upper plate area, the smaller the suction pressure is. (3) The installation speed is fast enough to allow the installation of a single tube in a few hours. (4) It is possible to pull out with the positive pressure generated by injecting water into the suction base. (5) It is advantageous in that the penetration resistance is reduced by the seepage of the submarine bed at the bottom of the foundation at the time of installation.

In addition, such a structure using the suction foundation can be installed (1) regardless of the depth of water, (2) can be installed in a short period of 1 to 2 days, and a large base can be installed in the seabed , (3) Suction after installation Since the inside of the foundation becomes airtight, a suction pressure is generated inside the suction base by drawing, and the suction pressure acts as resistance force (or ground force) (4) there is no need to improve the ground (especially, there is a soft ground in the surface layer and a glass layer in the lower layer, which is sandy soil in the lower layer), (5) the preceding load and the load There is an advantage of being able to experiment.

There is a possibility that the suction foundation is eccentric by the drawing load when the structure is installed on such a suction foundation. This is because the pullout supporting force corresponding to the pull load is generated only by the outer wall of the conventional suction foundation. Once it is eccentric, it is very difficult to solve, and installing the structure in such a state that the shaft is not maintained will cause problems in operation of the equipment.

There have been various conventional methods for adjusting the level of the suction foundation to prevent such eccentricity of the suction foundation.

Patent Document 10-1047092 proposes a guide device for improving the verticality in the installation of a marine structure for offshore wind power generation. However, this is not a fundamental solution for installing a ship on a foundation ship installed at the time of penetration, There are still difficult disadvantages.

In the patent 10-1044752, an inclination correcting device is provided in the installation of an offshore wind power plant, but since the suction piece is unnecessary on the suction foundation, the function of the transition piece is reduced to the role of vertical adjustment, There are disadvantages of instability and air enlargement, which is not a fundamental solution, and there is still a disadvantage in that it is difficult to precisely construct a cylinder by utilizing the pushing force of the cylinder.

In the Japanese Patent Application No. 10-1044753, there is provided an apparatus for correcting the offshore wind turbine tilt using an internal compartment, but it has a drawback that it is difficult to finely adjust the internal tilt due to the adjustment of the vertical degree by controlling the internal pressure.

Therefore, there is a need for a suction foundation for quickly and accurately adjusting the vertical degree when using a transition piece or without a grouting operation.

In the following detailed description of the operation principle of the preferred embodiment of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may unnecessarily obscure the subject matter of the present invention.

The same reference numerals are used for portions having similar functions and functions throughout the drawings. Throughout the specification, when a part is connected to another part, it includes not only a case where it is directly connected but also a case where the other part is indirectly connected with another part in between. In addition, the inclusion of an element does not exclude other elements, but may include other elements, unless specifically stated otherwise.

< Suction Foundation >

3 is a projection view of a suction foundation in accordance with an embodiment of the present invention. 3, the suction foundation 1 according to an embodiment of the present invention may include a main body 3, a regulating portion 10, and an internal supporting portion 12. As shown in FIG.

The main body 3 can be constructed in the form of a cylinder having an upper portion closed by an upper plate and a lower portion opened like a conventional suction foundation. Finally, it is composed of a top plate and a cylinder of a cylindrical shape. In addition, in order to perform the purpose and function of a conventional suction foundation, the discharge port and the injection port may be provided on the upper plate or the side surface for discharge and injection of seawater, and a ring for use as a point of application . The main body 3 is provided with the adjusting portion 10 and the inner supporting portion 12 therein.

The regulating section 10 may be constituted by a hydraulic cylinder or a pneumatic cylinder. One side of which is connected to the upper plate of the main body 3 and the other side of which is connected to the internal support portion 12, and at least one in the vertical direction can be constituted. And serves to determine the penetration depth of the suction foundation 1 against the tube input applied to the inner support portion 12. [ If it is fixed, the penetration depth is not changed, and when it is released, penetration depth is deepened by the tube input. It is possible to align the level with less force than when pushing and leveling, because it is not horizontal but pushing and lowering the submarine layer 40 with a hydraulic or pneumatic cylinder, .

The inner supporting portion 12 may be formed of a circular plate connected to the other side of the adjusting portion 10 and configured to be in parallel with the upper plate of the main body 3. [ It is possible to efficiently apply a resistance force to the seabed layer 40 under the suction foundation 1. [ This is because the penetration generated in the seabed layer 40 by seawater suction destroys the seabed layer 40 and imparts resistance to the seabed layer 40 whose strength is lowered is advantageous for the original plate having a large area.

At this time, in order to prevent the inside of the suction foundation 1 from being partitioned, the original plate may be made smaller than the cross section of the suction foundation 1, or a plurality of holes 14 may be formed in the internal support portion 12. This is because, when the seawater is sucked from the upper part of the suction foundation 1, only the seawater on the inner supporting part 12 is sucked, and no tube input is generated. Sand or the like may pass through the hole 14, but it is not disturbed by the penetration depth control.

The penetration depth of the suction foundation 1 can be determined through the adjustment part 10 and the internal support part 12 as described above. So that the horizontal of the suction foundation assembly 2 constituted by connecting a plurality of suction bases 1 is adjusted. According to the present invention, the adjustment is repeated while fixing and releasing the adjusting part (10), for example, the hydraulic cylinder. This requires a much smaller output than a hydraulic cylinder, because it aligns the hydraulic cylinders in a fixed or contracted manner.

At this time, after the depth of penetration of the suction foundation 1 is determined, the first fixing member 30 can be filled between the inner supporting portion 12 and the upper plate of the main body 3. The first fixing member 30 can be made of concrete and can be in contact with seawater, so that environmental conditions are severe. Concrete using denser aggregate is preferable because it has a low water cement ratio with high durability and strength.

<Suction foundation assembly>

The suction foundation assembly 2 can be provided with a mounting base for installing the marine structure. The first and second embodiments will be considered depending on the type of the mounting base. 4 is a projection view of a suction foundation assembly in accordance with a first embodiment of the present invention. 4, the suction foundation assembly 2 according to the first embodiment of the present invention can be constructed in combination with the tripod 20.

The suction foundation 1 is constructed as described above, and the suction foundation assembly 2 can be constituted by a plurality of suction bases 1. Preferably three vertexes of an equilateral triangle. The top plate is formed on one plane and can be configured parallel to each other. They may be arranged so as to be in contact with each other on the side surface, or may be disposed apart from each other by a certain distance. This will depend on the characteristics of the subsea bed being installed.

A plurality of suction bases 1 may be coupled to the lower end of the tripod 20, and a tower of an offshore structure, for example, an offshore wind turbine, may be formed at the upper end. The shape of the tripod 20 may be a conventional tripod.

After the suction foundation assembly 2 is leveled by the adjustment section 10 of each suction foundation 1, the first fixing member 30 is injected into each suction foundation 1 to fix the depth of penetration The second foundation member 32 is injected into the suction foundation assembly 2 by installing a cofferdam made of a rubber material or the like between the suction foundation assembly 2 and the bottom of the sea floor, And the bottom layer can be closely fixed to each other. At this time, the second fixing member 32 may be made of concrete like the first fixing member 30.

5 is a projection view of a suction foundation assembly in accordance with a second embodiment of the present invention. As shown in FIG. 5, the suction foundation assembly 2 according to the second embodiment of the present invention may be constructed in combination with a caisson 22 composed of gravity type concrete. That is, a gravity-suction-based hybrid basis.

The suction foundation 1 is constructed as described above, and the suction foundation assembly 2 can be constituted by a plurality of suction bases 1. Preferably three vertexes of an equilateral triangle. The top plate is formed on one plane and can be configured parallel to each other. They may be arranged so as to be in contact with each other on the side surface, or may be disposed apart from each other by a certain distance. This will depend on the characteristics of the subsea bed being installed. And can be inserted and coupled to the lower surface of the caisson 22.

The caisson 22 may be constructed of a conventional caisson 22 used for a gravity-type marine foundation, and gravity type is relatively inexpensive to manufacture and install as compared with a steel structure, and can be floated in water by buoyancy, The cost of moving is reduced, and since the concrete is filled in the inside, it is easy to install. However, there is a disadvantage that a hard ground condition which is disadvantageous in dismantling and able to withstand a relatively heavy weight is required and a separate manufacturing site is required. At this time, the hybrid foundation formed by coupling the suction foundation 1 to the lower end portion of the caisson 22 has an advantage that the suction force is reinforced by the suction foundation 1 even if a slightly small gravity type foundation is used. The caisson 22 may be replaced by a partition wall.

The second embodiment of the present invention can also provide a cofferdam between the suction foundation assembly 2 and the seabed layer so that the second fixing member 32 is injected and hardened so that the seafloor assembly 2 and the underside layer can be tightly fixed .

The construction method of the second embodiment of the present invention is as follows. First, the buoyant force is applied to the installation site over the sea surface, and then the concrete is partially filled in. When reaching the seabed floor, a plurality of suction bases 1 are penetrated through the weight of the suction or the concrete filled in the caissons 22, and the level is adjusted by using the adjusting portion 10. The first fixing member 30 or the second fixing member 32 may be injected and solidified to fix the horizontal state. Finally, concrete is filled in the caisson 22 or the inside of the partition wall.

<Suction foundation construction method>

FIGS. 6A, 6B, 6C, and 6D are conceptual views illustrating a basic construction method for a suction according to an embodiment of the present invention, and FIG. 7 is a flowchart illustrating a basic construction method for a suction according to an embodiment of the present invention. 6A, 6B, 6C, 6D, and 7, the suction basic construction method according to one embodiment of the present invention includes a penetration step S10, a horizontal adjustment step S20, a fixing step S30, (S40).

The penetration step S10 is a step in which the suction foundation assembly 2 is disposed in the seabed layer 40 in the first and second embodiments of the present invention and the seawater in the suction foundation 1 is sucked into the suction foundation assembly 2 Is partially penetrated into the sea bed layer 40. [ It is common that the seabed layer 40 is not parallel to the sea surface, as shown in Fig. Therefore, in order to maintain the horizontal level at the time of intrusion, the penetration depth of each suction foundation 1 should correspond to the seabed layer 40. The step of leveling the suction foundation assembly 2 by adjusting the penetration depths respectively is a horizontal adjustment step S20.

In the horizontal adjustment step S20, the adjustment unit 10 of each suction foundation 1 is separately controlled and the suction foundation assembly is leveled while repeating fixing and releasing. The penetration depth of the suction foundation 1 is fixed when the adjustment part 10 is fixed and the penetration depth is deepened by the tube input of the suction foundation 1 when the adjustment part 10 is released.

In the fixing step S30, the first fixing member is injected into the respective suction bases and solidified to fix the depth of penetration. The first fixing member 30 is preferably made of concrete as described above. As a result, the penetration depth of the suction base 1 is fixed, so that the horizontal level of the suction base assembly 2 is kept fixed.

The adhesion step S40 is a step in which the seam bottom layer 40 and the suction foundation assembly 2 are sealed with a copper dam or the like and the second fixing member is injected and solidified to form the sea floor layer 40 and the suction foundation assembly 2 And is closely contacted and fixed. The suction base assembly 2 is brought into close contact with the seabed layer 40, thereby enhancing the supporting force.

<Offshore wind power generation facility>

8 is a perspective view illustrating an offshore wind power generation facility using a suction foundation assembly according to an embodiment of the present invention. 8, the offshore wind power generation facility 9 according to an embodiment of the present invention may be constituted of a suction foundation assembly 2, a tower 5, and a power generation section 7. [

The suction foundation assembly 2 may be constructed as described above, and the first and second embodiments may all be used. In the case of using the general tripod 20 suction foundation according to the first embodiment of the present invention, it can be installed at a maximum depth of 1600 m without being restricted by the depth of installation, and is relatively simple in installation and heavy equipment is unnecessary. In the case of using the gravity-suction basic hybrid type according to the second embodiment, it can be applied to a lower depth of water, is simple and economical to manufacture, and may cause fatigue load on the member or corrosion on the connecting portion. However, according to the second embodiment of the present invention, there is an advantage that the arrangement of the seabed ground is not required to be greater than that of the conventional gravity type. In other words, the disadvantage that occurs when using the conventional gravity bases is that the bottom of the seabed soils are flattened to align horizontally, and the construction cost and the increase of air are eliminated.

The tower 5 may be coupled to the mounting base of the suction foundation assembly 2 and configured such that the longitudinal direction thereof is oriented vertically upward. And a power generation section 7 for wind power generation may be provided at the end.

The power generating unit 7 may be configured in the same manner as a conventional offshore wind power generating facility, and may be configured of a rotating unit including a rotor and a blade, and a nacelle housing a generator that generates power by rotation of the rotating unit.

When the offshore wind power generation facility 9 is installed using the suction foundation assembly 2 according to the present invention, it is easy to align the horizontally, and the horizontally maintained by the first and second fixing members 30, The effect will be generated.

The size, position, and arrangement of the suction foundation 1, the suction foundation assembly 2, and the adjustment portion 10 are not limited to those shown in the drawings. In order to achieve the object of the present invention, The strength and the type of marine structure.

As described above, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention.
