Description

The present invention relates to a transfer support device capable of transferring a person from a ship to an offshore wind power generation facility.

In recent years, expectations for renewable energy have been increasing in order to counter global warming and improve the energy self-sufficiency rate. In particular, Japan, which is a maritime nation, has high expectations for the future of power generation projects in the ocean.

On the other hand, among renewable energies, in wind power generation, maintenance is the key to securing the operating rate (power generation amount). In offshore wind power generation, which is one of the wind power generation, maintenance is also important to secure the operation rate, but maintenance is greatly affected by the transfer of people from the access ship to the offshore wind power generation facility due to the marine weather. Is not easy to do stably and safely. Therefore, there is a demand for a transfer support device capable of stably and safely transferring a person.

Such a transfer support device is, for example, a transfer support device that connects a first floating body and a second floating body, which are floating bodies that move irregularly together, and is extended from the first floating body and is relative to each other. It is characterized by having a connecting body that is flexible enough to absorb a specific movement and can move a person, and an adsorbent that is provided at the tip of the connecting body and can be adsorbed on the outer wall of the second floating body. It is a transfer support device (see Patent Document 1) and a transfer support device that is bridged between a ship and an offshore wind power generator so that a person can cross it. The main body, which swells in a shape that allows the wind turbine to cross, and is installed on both sides of the main body in the width direction, and is stretched between the ship and the offshore wind power generator. It is equipped with a hanging cable that can hang the main body in the handed state, and the main body is equipped with handrails on both sides in the width direction, and each hanging cable has one end connected to the ship and the other end. A transfer support device (see Patent Document 2) having a hook-shaped coupling means capable of coupling to a predetermined support member provided on the outer wall of an offshore wind power generator by hooking has been proposed.

Is suppressed, and the bridge body 10 is held horizontally. At this time, the upper board support control member 62 supports the upper board 41 from below to suppress the swing, and absorbs the load due to the swing of the upper board 41 to reduce the swing of the bridge body 10.

FIG. 6 shows a schematic side view of a state in which the tip fixing member 11 of the transfer support device 1 fixes the bridge main body 10 to the offshore wind power generation facility 3.
As shown in FIG. 6B, the bridge body 10 is horizontal immediately after the transfer support device 1 is bridged to the offshore wind power generation facility 3.

On the other hand, as shown in FIG. 6 (a), the tip of the access ship 2 descends due to fluctuations in the sea level such as waves and swells, and as shown in FIG. 6 (c), the tip of the access ship 2 rises. However, even if the bridge body 10 is tilted in this way, the bridge body 10 sways without imposing a load on the tip fixing member 11 due to the pitch direction support portion 70 connecting the base end of the bridge body 10 and the upper plate 41. Is suppressed, and the bridge body 10 is held horizontally.

Next, the procedure for transferring a person to the offshore wind power generation facility 3 by the access ship 2 on the ocean using the transfer support device 1 will be described.

First, the access ship 2 is brought close to the offshore wind power generation facility 3 floating in the ocean, and the fender 90 at the tip of the access ship 2 is brought into contact with the poles 30a and 30b of the offshore wind power generation facility 3 to berth (berth). (FIG. 1 and FIG. 7 (a)). Subsequently, the bridge body slide plate 22 of the bridge body 10 of the transfer support device 1 fixed to the bow side of the access ship 2 is advanced, and the two poles of the offshore wind power generation facility 3 are moved by the grip portion 33 of the tip fixing member 11. 30a and 30b are sandwiched and gripped (FIG. 3). Subsequently, the user 100 walks from the access ship 2 on the transfer support device 1 and moves to the offshore wind power generation facility 3 (FIG. 7 (b)). As a result, the transfer work from the access ship 2 to the offshore wind power generation facility 3 is completed.

Further, when returning from the offshore wind power generation facility 3 to the access ship 2, the user 100 walks on the transfer support device 1 from the offshore wind power generation facility 3 and moves to the access ship 2. Subsequently, the tip fixing member 11 that grips the poles 30a and 30b is released, the bridge body slide plate 22 of the bridge body 10 is retracted to the retreat limit, and the access ship 2 is separated from the offshore wind power generation facility 3.

Next, the transfer support device according to another embodiment will be described. The members having the same configuration as the transfer support device 1 are designated by the same reference numerals and the description thereof will be omitted. This embodiment is different from the above embodiment in that each cylinder is provided as an auxiliary support portion of the bridge main body and the tip fixing member, and an upper plate support control member of the bridge main body control portion. 8A and 8B are schematic explanatory views of a transfer support device according to another embodiment of the present invention, FIG. 8A is a schematic plan view of the transfer support device, and FIG. 8B is a schematic rear view of the transfer support device. , (C) is a schematic side view of the transfer support device.

As shown in FIG. 8, in the transfer device 4 of another embodiment of the present invention, the lifting cylinders 86 and 87 as auxiliary support portions 13 for supporting the bridge body and the auxiliary support portions 13 for supporting the tip fixing member 11 are provided. The tip fixing member support cylinder 36 is provided.
Specifically, the auxiliary support portion 13 for supporting the bridge main body is installed on a base 14 provided in front of the bridge main body control unit 12, and two tower portions 80, which are erected on both sides of the bridge main body 10. The bridge main body is provided with 81, and the upper parts of the two tower portions 80 and 81 and the lifting cylinders 86 and 87 are connected to the side portions of the bridge main body 10 on the same side as the tower portions 80 and 81, respectively. The structure is such that 10 is lifted.

Further, in the auxiliary support portion 13 that supports the tip fixing member 11, the lower portion of the rod-shaped member 32 of the tip fixing member 11 and the connecting plate members 37 provided on both lower sides of the bridge body slide plate 22 are the tip fixing member support cylinders. It is connected to 36 and supports the tip fixing member 11 from below.
In the present embodiment, by providing the auxiliary support portion and each cylinder as the upper board support control member, it is possible to strengthen the control of the bridge body 10 and the tip fixing member 11 corresponding to the shaking of the ship 2. ..

Further, as shown in FIG. 8, the transfer device 4 of another embodiment of the present invention includes an upper plate support cylinder as an upper plate support control member 62. That is, the upper board support control member 62 is an upper board support cylinder provided on one side of the swing mechanism 61 on the intermediate board 40 in the left-right direction, and supports the upper board 41 from below to suppress swing. , It absorbs the load caused by the shaking of the upper board and suppresses the shaking of the bridge body 10.

The transfer support device of the present invention is industrially useful because it can be mounted on a ship and used.
