Technical Field
The utility model relates to a fan jacket structure for offshore wind power.
Background
Wind energy is one of the most mature, most scaled development conditions and commercial development prospects of the technology in the field of new energy as an efficient and clean energy. Compared with a land wind power plant, the offshore wind power plant is highly valued by more and more countries due to the advantages of superior wind resources, environmental protection, land conservation, large scale and the like. However, offshore engineering is constructed on the sea, so that the working condition is severe, the offshore wind turbine foundation construction method has the characteristics of short construction time, high construction difficulty, great influence of natural conditions such as weather and sea conditions and the like, and the requirement on offshore wind turbine foundation construction is higher.
The jacket foundation is generally applied to sea areas with the water depth of 20 m-40 m, and the larger the water depth is, the higher the jacket foundation is, and the heavier the foundation is. When the water depth exceeds a certain water depth, the jacket foundation is higher and heavier, the manufacturing level of a processing factory is higher, the matched production and manufacturing field is larger, and in addition, the jacket is stronger in the capacity of matched transportation equipment and hoisting equipment when being transported to a planned sea area. Therefore, the construction cost of the jacket foundation is greatly increased.
