Description

Fish Shelter For The Offshore Wind Turbine, which is installed adjacent to the foundation structure of an offshore wind turbine.

The present invention relates to a reef structure installed adjacent to the foundation structure of an offshore wind power generator, and more specifically, it not only develops by using wind, but also supports the habitat of underwater fish and has a seaweed field and a reef function that can both preserve the ecosystem. It relates to a reef structure installed adjacent to the foundation structure of an offshore wind power generator.

Wind power is a power generation technology that generates electricity by converting wind energy.

In the case of offshore wind turbines, each component of the wind turbine is designed and coated to prevent corrosion damage due to salt. In addition, in the case of an offshore wind power generator, it must be stably installed on the sea floor so as to ensure stable operation even with changes in the weather at sea.

Therefore, in the case of offshore wind power generators, foundation work is very important. At this time, as a foundation work that can be applied to offshore wind power generators, there are four types as representative examples.

As a first example, there is a concrete caisson type. It is easy to manufacture and install, so it was used in the early offshore wind farms. It was applied to Vindeby, Middelgrunden, and Nysted offshore wind farms. It can be used in a relatively shallow depth of 6-10m and maintains its position by its own weight and frictional force on the sea floor. The foundation diameter is 12 to 15m, and there is a possibility of causing stability problems due to eccentric slope in poor ground.

As a second example, there is a mono-fixed material type (Monopile type). It is the most widely used offshore wind farm basic method and can be installed at a depth of 25 to 30m. It has been applied to the Horns Rev, North Hoyle, and Scroby Sands offshore wind farms, and it is economical when used in a large-scale complex by driving or drilling a large diameter fixing member (pile) on the sea floor. The base diameter is 3 to 3.5m, and there are fatigue loads or corrosion problems on the member.

As a third example, there is a jacket type. Currently, it is a type that has shown much interest in offshore wind farms and is being demonstrated, and can be installed at a depth of 20 to 80 m. This type, applied in the UK's "The Talisman Beatrice Wind Farm Demonstrator" project, is supported by a jacketed structure and fixed to the seabed with piles or piles. It is a deep-sea structure and has a high level of reliability due to its high performance. As with the mono-fixed material type, it is economical if it is used for large-scale complex construction.

As a fourth example, there is a floating type. The floating type, which can be said to be an essential task of future deep-sea wind power generation, is being studied by many wind power companies to be able to install it at a depth of 40 to 900 m.

The present invention relates to a reef structure installed adjacent to the foundation structure in the type of the first to the third as an example.

As can be seen from the above, the most important matter in offshore wind power generation is in the process of installing offshore wind power generators offshore. There is a problem in that it is difficult and enormous cost is required for the process of performing foundation work and installing various wind turbines offshore.

In addition, since the function is simplified by using only a wind turbine, the offshore wind turbine does not have various functions compared to the high installation cost and has a simple problem.

In order to solve this problem, as shown in FIG. 1, a technology for forming an artificial reef structure in the foundation structure of an offshore wind turbine has been developed.

However, the artificial reef structure shown in FIG. 1 is a structure manufactured through a process of pouring concrete corresponding to the entire structure at once, and the installation process requires a lot of cost and time.

Therefore, there is a need for a technology capable of solving the problems according to the prior art mentioned above.
