Problems solved by technology

[0006] However, in the conventional construction method as described above, it is expected that the installation work at sea will require a huge cost from the viewpoint of the installation work time and the cost of the pontoon, and its reduction and improvement have become a big problem.
[0007] The problems of installation construction time can be listed as follows: Since the installation sea area of ​​the windmill is farther from the coast than the existing situation, the return time from the gathering port to the installation sea area is increased; The time required to raise and lower the pontoon by means of the device is increased; the number of windmills that can be transported at one time by the equipment currently in use is reduced due to the increase in the size of the windmills used, and the efficiency of the operation in terms of time is reduced.
[0008] The problems of the cost of floating boats can be listed as follows: the number of working floating boats increases due to the increase in the amount of work; the size of the floating boat, jacking device, and the capacity of the deck crane increase with the increase in the size of the windmill used, so Increased boat price for pontoons

no. 1 Embodiment approach ］

[0096] Next, a first embodiment of the present invention will be described.

[0097] figure 1 3 shows a ship 1 for installing an offshore wind turbine (hereinafter simply referred to as "ship 1") according to the present embodiment, and shows a state in which a wind turbine 3 is mounted on the ship 1 at a pier. This ship 1 performs a so-called integrated wind turbine installation in which a wind turbine assembled in advance is directly transported to a wind turbine installation sea area and installed.

[0098] As shown in the figure, the tower 5, the nacelle 7, and the wind turbine blades 9 are assembled in advance on the land side, and the wind turbine 3 is directly mounted on the ship 1 . When loading the windmill 3 onto the ship 1 from the land side, the windmill 3 is hoisted and loaded by a self-propelled land crane 10 such as a jib crane. figure 1 The middle represents the state that the windmill 3 is hoisted by the land crane 10, figure 2 A state in which the hoisted...

no. 2 Embodiment approach ］

[0120] Next, use Figure 7 to Figure 9B A second embodiment of the present invention will be described.

[0121] Compared with the first embodiment, the present embodiment differs in the method of supporting the windmill 3 for conveyance, but is the same in other respects, so the differences will be described below. Therefore, in this embodiment, a so-called wind turbine integrated installation is carried out in which a wind turbine assembled in advance is directly transported to a wind turbine installation sea area and installed in the same manner as in the first embodiment.

[0122] In this embodiment, the operating device 29 is arranged on the deck and travels along the front and rear direction of the hull on the deck side rails provided on the deck. Such as Figure 9A , Figure 9B As shown, the handling device 29 lifts the tower 5 of the windmill 3 from below. Specifically, the lower end of the tower 5 is locked with the protrusion 35 provided below the tower 5 and the...

no. 3 Embodiment approach ］

[0130] Next, use Figure 10 to Figure 12B A third embodiment of the present invention will be described.

[0131] This embodiment differs in that a cart 42 is used instead of the operating device 29 of the second embodiment, but is the same in other respects, so differences will be described below. Therefore, in this embodiment, a so-called wind turbine integrated installation is carried out in which a wind turbine assembled in advance is directly transported to a wind turbine installation sea area and installed in the same manner as the first embodiment and the second embodiment.

[0132] Figure 10 The middle circle shows the state where the windmill 3 is installed on the tower base 30 . As shown in this figure, the ship 1 is equipped with the rail extension part 15 and the support device 31 similarly to 2nd Embodiment.

[0133] In this embodiment, the dolly 42 (refer to Figure 12A , Figure 12B ) to transport the windmill 3. Specifically, the lower end of the tower 5...

Abstract

Provided are a ship for installing offshore wind turbines and a method for installing offshore wind turbines using the ship, whereby wind turbines can be installed by simple operations when pre-assembled wind turbines are transported and installed at sea. In the ship for installing offshore wind turbines (1), multiple wind turbines (3), each obtained by assembling a tower (5), a nacelle (7) and rotor blades (9), are loaded side-by-side in the longitudinal direction of the hull, the ship is towed or self-navigated to an area of sea where the wind turbines are to be installed, and the wind turbines (3) are installed on pre-installed foundations. The ship for installing offshore wind turbines (1) is provided with a handling apparatus (16) that travels in the longitudinal direction of the hull, and holds and lifts the tower (5) of a wind turbine (3). When installing a wind turbine (3) on a foundation, the handling apparatus (16) travels to the foundation positioned at the rear of the hull while holding and lifting the tower (5) of the wind turbine (3), and installs the wind turbine (3) on the foundation.

Description

technical field [0001] The present invention relates to a ship for installing an offshore windmill and a method for installing an offshore windmill using the ship. Background technique [0002] Currently, construction of offshore windmills is prevailing in Europe, and in the future, the scale of windmills tends to expand and the amount of installation work at sea tends to increase significantly. Furthermore, it is also planned to install windmills in deep sea waters farther from the coast than the sea area where the windmills are installed, and the windmills themselves tend to be larger in size. [0003] The installation work of offshore windmills uses self-elevating pontoons equipped with jacking devices and deck cranes. Divided or partially joined wind turbine blades, a nacelle containing a generator / gearbox, wind turbine parts such as a tower, and tower foundations (foundation )structure. Then, after the self-propelled or towed self-propelled floating boat is transport...
