Description

Ship dedicated to installing wind power generators {SHIP FOR INSTALLING WIND POWER GENERATOR}

The present invention relates to a vessel dedicated to the installation of wind power generators.

Generally, offshore wind power generators are manufactured on land by dividing the parts into several generator units (blades, nacelles, towers, etc.), and then the manufactured generator units are transported on a dedicated installation vessel (for example, a wind turbine installation vessel (WTIV, Wind Turbine) It is being transported and installed at sea by Installation Vessel).

For the installation work of the offshore wind power generator, the dedicated installation vessel is loaded with the generator unit, moves to the installation location of the offshore wind power generator, fixes the leg by sinking it to the sea floor at the installation location, and then floats the hull out of the water. do.

However, due to the rapid growth of the offshore wind power generator market, the shortage of dedicated installation vessels for the installation of large-capacity offshore wind power generators is becoming a major problem. In the case of commercially available dedicated installation vessels, they are limited to the installation of offshore wind power generators with a power generation capacity of 8MW, and when installing offshore wind power generators with a power generation capacity of 12MW, problems such as crane capacity and boom out-distance arise. may occur.

Additionally, the increase in power generation capacity of offshore wind power generators is linked to the increase in turbine weight, which means that dedicated installation ships must operate larger cargo weights. When the cargo weight increases, the weight of the hull and the cargo loaded on it increases. As a result, the jacking system of the dedicated installation vessel receives a large load. If these series of problems work together, the size of the offshore wind power generator must be increased, and the corresponding equipment capacity and leg design must be changed simultaneously, which can cause significant difficulties in developing new models.

As shown in Figures 1 to 4, a ship 10 dedicated to the installation of a wind power generator according to an embodiment of the present invention is provided with a side platform 300 on the side of the hull 100 on which the generator unit can be loaded. , the roll stability of the ship can be improved by increasing the line width. To implement this, the installation-only vessel 10 may include a hull 100, a fit-in rail 200, and a side platform 300.

Specifically, the hull 100 may be a floating structure having any three-dimensional structure on which the legs 110 can be installed. Various equipment and structures may be placed on the hull 100. As an example, the hull 100 may be loaded with a generator unit (blade, nacelle, tower, etc.), which is a major component of a wind power generator.

In this embodiment, the vessel 10 dedicated to installing an offshore wind turbine may be a wind turbine installation vessel (WTIV, Wind Turbine Installation Vessel) or a jackup platform, but is not limited thereto, and is a floating structure having a jackup mode. All of these can be included.

The hull 100 can be operated in transit mode and jackup mode. The hull 100 can be moved in sailing mode to the location where the offshore wind power generator is to be installed, then switched to jack-up mode and the legs 110 can be fixed to the seafloor through spud cans. The legs 110 are installed to be movable in the vertical direction on the hull 100, which can be operated in jack-up mode, so that the hull 100 can be fixed to the sea floor through a spud can.

The fit-in rail 200 may be installed on the side of the hull 100. The fit-in rail 200 may have a rail structure in which the side platform 300 is removable. As an example, the fit-in rail 200 may be composed of a first male rail 210 and a second male rail 220. These first male rails 210 and second male rails 220 may be installed spaced apart from each other on the upper and lower sides of the hull 100. The first arm rail 341 and the second arm rail 342 of the side platform 300 may be slidingly coupled to the first male rail 210 and the second male rail 220.

A plurality of fit-in rails 200 may be provided along the side edge of the hull 100 and spaced apart in the longitudinal direction of the hull 100. The side platform 300 may be selectively coupled to the plurality of fit-in rails 200.

In this embodiment, the fit-in rails 200 are composed of three pieces spaced apart along the side edge of the hull 100, and three side platforms 300 are respectively coupled to these three fit-in rails 200. It is not limited, and the number of fit-in rails 200 and the number of side platforms 300 mounted on the fit-in rails 200 may vary. As an example, when three fit-in rails 200 are spaced apart from the side edge of the hull 100, two side platforms 300, which are less than three, can be optionally mounted on the three fit-in rails 200. .

The number of side platforms 300 may be at least less than the number of fit-in rails 200. Additionally, the side platform 300 may be selectively mounted on a plurality of fit-in rails 200 and may be separated from the fit-in rails 200. For example, when three fit-in rails 200 are spaced apart from the side edge of the hull 100, the side platform 300 is selectively mounted on three or fewer fit-in rails 200. It can be.

At least one of the generator units may be loaded on the side platform 300. For example, at least a portion of a tower, which is relatively long among the generator units, may be horizontally loaded and supported on the side platform 300.

This side platform 300 may include a blast tank 310, a side keel 320, a guide supporter 330, a first arm rail 341, and a second arm rail 342.

The blast tank 310 can provide a storage space that can accommodate seawater. When the installation-only vessel is switched to jack-up mode and jacked up, seawater may be introduced into the blast tank 310 to increase the preload value of the installation-only vessel. When the leg 110 of the installation-only vessel completes stable penetration into the seafloor, the seawater contained in the blast tank 310 can be discharged to the outside.

The side keel 320 may be provided at the lower part of the blast tank 310 to reduce lateral motion. Since the side keel 320 is formed sharply to protrude further than the lower end of the leg 110, when the installation-only vessel is in sailing mode, the fluid resistance of the installation-only vessel can be reduced, ultimately increasing the ship speed of the installation-only vessel. You can do it.

The guide supporter 330 may be installed in the form of a support at the edge of the blast tank 310. The guide supporter 330 is provided in the form of a support that surrounds the generator unit mounted on the upper surface of the blast tank 310, and thus can prevent the blast tank 310 from being separated from the side platform 300.

To secure the generator unit, a binding mechanism that surrounds the entire generator unit may be fixed to the guide supporter 330. The binding mechanism may include a binding rope that can secure the generator unit to the blast tank 310.

The first arm rail 341 and the second arm rail 342 may be provided on the side of the blast tank 310. The first arm rail 341 and the second arm rail 342 are installed spaced apart from each other on the upper and lower sides of the blast tank 310 to correspond to the first male rail 210 and the second male rail 220. You can. These first arm rails 341 and second arm rails 342 may be detachably and slidingly coupled to the first male rail 210 and the second male rail 220 of the fit-in rail 200, respectively.

Figure 5 is a block diagram showing the control flow of an installation-only vessel according to another embodiment of the present invention.

As shown in Figure 5, according to another embodiment of the present invention, the side platform 300 includes a blast tank 310, a side keel 320, a guide supporter 330, a first arm rail 341, and a first arm rail 341. 2 It may include an arm rail 342, an on/off valve 350, a seawater pump 360, a detection sensor 370, and a controller 380.

In describing another embodiment of the present invention, when compared to the above-described embodiment, the side platform 300 includes an opening/closing valve 350, a seawater pump 360, a detection sensor 370, and a controller 380. Since there is a difference in that more is included, the following will mainly explain the differences, and the same description and reference numerals will be used.

The open/close valve 350 is a valve that selectively opens or blocks the flow of seawater, and may be provided at the inlet and outlet of the blast tank 310. The opening/closing valve 350 can control the flow of seawater supplied to the blast tank 310 under the control of the controller 380.

The seawater pump 360 is a pump that transports seawater by suction and compression, and can control the amount of seawater flowing in or out through the opening/closing valve 350. The seawater pump 360 can pump seawater to allow external seawater to flow into the storage space of the blast tank 310, or to discharge seawater within the storage space to the outside of the blast tank 310.

The detection sensor 370 may be a type of sensor that can detect a change from the sailing mode to the jack-up mode of an installation-only ship or detect the completion of the jack-up mode. As an example, the detection sensor 370 may be a contact sensor, a pressure sensor, or a laser sensor that can detect the position of the leg 110 or the contact (pressure) state of the leg 110 with respect to the sea floor. Sensing information about the leg 110 detected by the detection sensor 370 may be applied to the controller 380.

Based on the detection information from the detection sensor 370, the controller 380 determines that the installation-only vessel has switched to jack-up mode and is jacking up, or that the leg 110 of the installation-only vessel is on the sea floor. It can be judged that stable penetration has been completed. For example, when changing from sailing mode to jack-up mode, if the motion of the leg 110 is detected by the detection sensor 370, the controller 380 may determine that the installation-only vessel has switched to jack-up mode and is jacking up. there is. In addition, when the leg 110 penetrates the seafloor, if the stoppage of operation of the leg 110 is detected by the detection sensor 370, the trawler ensures that the leg 110 of the installation-only vessel has completed stable penetration into the seafloor. It can be judged that

And the controller 380 can control the operation of the seawater pump 360 and the opening and closing of the on-off valve 350 based on the sensing information from the detection sensor 370. For example, if the controller 380 determines that the installation-only vessel has switched to jack-up mode and is jacking up based on the received detection information, the controller 380 operates the sea water pump 360 and the The opening/closing valve 350 can be adjusted. In addition, based on the detection information of the detection sensor 370, the controller 380 determines that the leg 110 of the installation-only vessel has completed stable penetration into the seafloor, so that the seawater contained in the storage space is discharged to the outside. The seawater pump 360 and the opening/closing valve 350 can be adjusted.

In this way, when it is determined that the installation-only vessel is switched to jack-up mode and is being jacked up, the controller 380 adjusts the sea water pump 360 and the opening/closing valve 350 so that sea water flows into the blast tank 310, The preload value of a dedicated ship can be increased. In addition, when the leg 110 of the installation-only ship completes stable penetration into the seafloor, the controller 380 adjusts the seawater pump 360 and the opening/closing valve 350 so that seawater is discharged from the blast tank 310. , the weight of the hull 100 can be reduced for smooth lifting and lowering of the hull 100.

This controller 380 may be implemented by an arithmetic device including a microprocessor, memory, etc., and since the implementation method is obvious to those skilled in the art, further detailed description will be omitted.

As described above, the present invention can improve roll stability by increasing the ship width by constructing a side platform on which a generator unit can be loaded on the side of the hull, and by providing a side keel at the lower part of the side platform. , it has excellent advantages such as being able to implement the ship's bilge kill function.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. You will be able to understand it. For example, a person skilled in the art may change the material, size, etc. of each component depending on the field of application, or combine or substitute embodiments to implement the present invention in a form not clearly disclosed in the embodiments of the present invention, but this is also the present invention. It does not go beyond the scope of. Therefore, the embodiments described above are illustrative in all respects and should not be understood as limiting, and such modified embodiments should be considered to be included in the technical idea described in the claims of the present invention.
