Embodiments 1 to 4 will be described with respect to a form in which the support structure of the offshore wind power generation facility is directly slid and launched, that is, a form in which the support structure is slid and launched at least in a state where the surface of the support structure is in contact with the barge. explain.
(Embodiment 1)
In the present embodiment, after transporting the offshore wind power generation facility with the rotor facing upward on a barge that can be tilted on the barge, the base of the support structure is tilted at the installation location. A transportation installation method for installing an offshore wind power generation facility including a support structure by launching while sliding toward the side and a transportation installation barge that can be suitably used for this method will be described.

(Transportation installation method of offshore wind power generation facilities)
The transportation installation method according to the present embodiment includes (1) a process of mounting at least a support structure of an offshore wind power generation facility on a barge (loading process), and (2) an offshore wind power generation of the support structure by the barge. A step of transporting to the installation location of the facility (transportation step); and (3) a step of installing the support structure on the sea by sliding and launching (installation step).

  In the mounting process, it is sufficient that at least the support structure is included in the product that is laid down and mounted on the barge. That is, in the mounting process, when (A) only the support structure is mounted, (B) when the integrated support structure and tower are mounted, (C) the support structure, tower, and nacelle are combined. In the case of mounting an integrated one, (D) any of cases in which a support structure, a tower, a nacelle, and a rotor are integrated is included. As shown in (B) to (D), by mounting at least a part of the offshore wind power generation facility in an integrated state with the support structure, dangerous installation work on the ocean is reduced, resulting in economic efficiency and safety. Will improve. For this reason, it is preferable that the tower, nacelle, and rotor of the offshore wind power generation facility are integrally mounted on the support structure.

In the transport process, when the tower, nacelle, and rotor are transported in an integrated manner, it is preferable to transport the rotor in a state where the rotor is laid down upward. Thereby, it can prevent that a rotor contacts with a barge and is damaged under the influence of a wave in a transportation process.
Alternatively, a plurality of support structures may be mounted on a barge at a time in the transportation process and transported, and the support structures may be sequentially installed one by one at the installation location in the installation process. If it does in this way, the transportation efficiency at the time of installing a plurality of support structures can be raised.

  The installation process is a process in which the support structure is erected on the sea by sliding on the advancing platform and launching. In the present embodiment, the support structure is slid using gravity by inclining the portion on which the support structure is placed. For example, an advancing platform inclined on a barge is provided, the support structure is locked by a locking means and transported, the lock is released at the installation location, and the support structure is slid using gravity to launch. You may let them. Moreover, you may make it slide by applying a force to a support structure, without inclining the part which has mounted the support structure. Smooth and safe installation can be realized by sliding the support structure to launch. By adopting a configuration in which the portion on which the support structure is placed is tilted and slid, gravity can be used, so that energy required for installation can be reduced. Moreover, it is preferable to decelerate the sliding of the support structure to achieve a sliding speed that ensures safe safety.

  In the present embodiment, the support structure is slid and launched toward the base side of the support structure, that is, toward the heavy side that is downward in the standing state. For this reason, a support structure can be installed in the state where the sliding direction was stabilized. “Standing” refers to installation such that the longitudinal direction of the support structure is the vertical direction (vertical direction).

(Transportation barge for offshore wind power generation facilities)
The transport installation barge of the offshore wind power generation facility of the present embodiment can be used in a transport installation method in which the support structure is directly slid by inclining in the installation process.
FIG. 1 is a schematic diagram showing an outline of a transportation installation barge (example 1) of the present embodiment. As shown in the figure, the transport installation barge 10 includes a main machine 11, a propeller 12, a travel stage 13, and a locking means 14, and an offshore wind turbine including a support structure 21, a tower 22, a nacelle 23, and a rotor 24. It is used for transport installation of the power generation facility 20.

  The transport installation barge 10 of this embodiment is a self-propelled type equipped with a main machine 11 and a propeller 12 as navigation means. For this reason, it is not necessary to prepare a towed ship. However, the transport installation barge of the present invention is not self-propelled, and the navigation means can be configured to be towed by another ship.

The advancing table 13 is provided on the transportation installation barge 10 in an inclined state in advance. And the advancing stand 13 is provided with the latching means 14 which latches the offshore wind power generation facility 20 in the vicinity of the termination | terminus part by the side of the launch of the mounting surface which mounts the offshore wind power generation facility 20. FIG. The locking means 14 can protrude from the mounting surface, and engages and locks with the base 25 of the support structure 21 in a protruding state. Then, the offshore wind power generation facility 20 in a state of being laid down on the advancing platform 13 is locked and mounted on the transport installation barge 10 for transport.
After the offshore wind power generation facility 20 is transported to the installation position, if the locking by the locking means 14 is released, the offshore wind power generation facility 20 on the advancing platform 13 can be slid to launch on the sea surface and standing.

FIG. 2 is a schematic diagram showing a state in which the advancing platform 13 is viewed from the direction of arrow A in FIG. As shown in the figure, two linear sliding mechanisms 15 are provided on the mounting surface of the advancing platform 13 on the side where the offshore wind power generation facility 20 is mounted. A recess 16 is formed between the linear sliding mechanisms 15.
The linear sliding mechanism 15 is provided along the longitudinal direction of the offshore wind power generation facility 20 so that the surface thereof is in line contact with the support structure 21 of the offshore wind power generation facility 20. And a part (protrusion part) of the nacelle 23 is located in the recessed part 16 between the linear sliding mechanisms 15, and the nacelle 23 does not contact the advancing base 13 surface. By providing the linear slide mechanism 15 on the advancing platform 13, the nacelle 23 is prevented from coming into contact with the surface of the advancing platform 13, and the offshore wind power generation facility 20 is prevented from being damaged in the transportation process and the installation process. In addition, the linear sliding mechanism 15 may form a contact part with the support structure 21 in convex shape. Further, by forming the contact portion of the linear sliding mechanism 15 with a slippery material, the offshore wind power generation facility 20 can be slid and launched with a small inclination.

  FIG. 3 is a schematic diagram showing an outline of the transportation installation barge (example 2) of the present embodiment. The transport installation barge 10 shown in the figure includes a traveling stage 17 whose end portion on the launch side is curved in the water surface direction instead of the traveling stage 13. Due to the advancing platform 17 provided with this curvature, the support structure 21 smoothly changes its direction toward the water surface at the time of launch, so that the offshore wind power generation facility 20 can be launched more smoothly.

Means for decelerating to a safe sliding speed when the offshore wind power generation facility 20 slides on the advancing platform 13 will be described with reference to FIGS.
FIG. 4 is a schematic diagram showing an outline of the transport installation barge (example 3) according to the first embodiment. As shown in the figure, the transport installation barge 10 includes a wire 18 that controls the speed of the offshore wind power generation facility 20 during sliding. The wire 18 has its one end fixed to the support structure 21 of the offshore wind power generation facility 20, and controls the length of the wire 18 that is fed out from the transport installation barge 10, thereby sliding the offshore wind power generation facility 20 in the installation process. The speed of the hour is controlled within a safe range. Therefore, the speed of the center of gravity displacement caused by the sliding of the offshore wind power generation facility 20 can be suppressed, and the installation of the offshore wind power generation facility 20 can be made smoother and safer.

  FIG. 5 is a schematic diagram showing an outline of the transportation installation barge (example 3) of the first embodiment. The transport installation barge 10 shown in the figure includes a brake mechanism 19 that controls the speed at which the offshore wind power generation facility 20 slides. The brake mechanism 19 controls the speed by braking the sliding of the offshore wind power generation facility 20. For example, the brake mechanism 19 and the offshore wind power generation facility 20 are adjusted by adjusting the force sandwiching the offshore wind power generation facility 20. It can comprise using the mechanism which controls the frictional resistance between. It is also possible to control the speed by configuring the brake mechanism 19 with a material having a large friction and controlling its rotation.

  The offshore wind power generation facility 20 may be either a fixed type in which the base portion 25 of the support structure 21 is fixed to the seabed or a floating type in which the base structure 25 is installed at a predetermined position while floating on the sea. Among these, if a floating body that is easy to adjust the position after standing on the sea in the installation process is used, it is not necessary to strictly control the position in the installation process.

  The shape and strength of the support structure and other members constituting the offshore wind power generation facility are usually set assuming an installed state. For this reason, in each process of standing the above-described offshore wind power generation facility from the sideways state, if an unexpected force such as bending stress is applied because the weight of the support structure or other members may be very heavy, May be damaged. Therefore, in this embodiment, a frame that serves as a protection mechanism such as a support structure and a reinforcement mechanism is provided. By performing the above steps while the support structure is supported by the frame, it is possible to prevent the support structure from being damaged when an unexpected force is applied. In addition, it is possible to protect related members and structures of the offshore wind power generation facility by the frame. And since a frame is collect | recovered after installation, it can be set as the structure suitable for being used at said each process. For this reason, if the barge side surface of a frame is made into a smooth shape, the indirect sliding of the support structure in an installation process can be made smooth.

  The installation process is a process in which the offshore wind power generation facility is erected on the sea by sliding and launching the support structure supported by the frame on the traveling platform. As described above, the frame functions as a protection mechanism, a reinforcement mechanism, and a sliding smoothing mechanism. For this reason, in addition to the support structure, the installation process may be performed in a state where at least one of the tower and the nacelle is supported by the frame. Thereby, the member supported by the frame can also be protected, reinforced, and smoothly slid.

In addition, a pulling device 121 used for pulling the frame 71 by the wire 18 is provided. Since the traction device 121 is movable in the ship side direction (vertical direction in FIG. 22) by the rail 122 provided on the transport installation barge 120, the traction device 71 that supports the three offshore wind power generation facilities 20 is pulled. The traction device 121 can be moved to a position suitable for the above.

All tilt. However, since each offshore wind power generation facility 20-1 to 20-3 is locked to the traction devices 121-1 to 13-3 via the wires 18-1 to 18-3, the traction device 121 via the wires 18-1 to 18-3. The sliding of the offshore wind power generation facilities 20-1 to 20-3 can be individually controlled by the 1-3. Therefore, the offshore wind power generation facility can be selectively slid and launched by the wire 18 for installation. For this reason, the offshore wind power generation facility 20 can be sequentially launched while slightly changing the installation location.

  FIG. 22 shows a combination of a number of traveling bases corresponding to a plurality of frames and one movable traction device, and FIG. 23 shows a number of traveling bases capable of mounting a plurality of frames and a number corresponding to a plurality of frames.
