Description
Technical Field
The invention relates to the field of offshore wind power anchoring systems, in particular to a novel offshore floating type wind turbine foundation.
Background
Wind energy is an important component of clean energy and has great development potential. The main utilization modes of wind energy at the present stage mainly comprise onshore wind power and offshore wind power, and the onshore wind power gradually approaches saturation due to the limitation of terrestrial resources in the long-term development process; compared with onshore wind power, offshore wind power has the advantages of being friendly to ecological environment, high in wind energy utilization efficiency, close to economically developed areas, capable of saving cost of conveying points and the like.
At present, offshore wind farms all over the world are mostly built in offshore areas with water depths lower than 50m, and are mainly based on fixed foundations. When the water depth exceeds 50-60m, most offshore wind power anchoring systems are floating foundations. The existing offshore floating type wind turbine foundation has some defects, and the development of a novel offshore floating type wind turbine foundation becomes the problem to be solved urgently in the field at present.
