Description

Technical Field

[0001] The invention relates to a floating offshore wind power system, belonging to the technical field of wind power equipment. Background Art

[0002] Floating offshore wind turbines refer to wind turbines installed on floating foundations. They are not restricted by water depth and seabed conditions and can make better use of offshore wind energy resources. From a technical perspective, more than a decade of experience in offshore oil and gas platform development has fully proved that floating structures have the ability to survive for a long time at sea. From a resource perspective, the deep sea area is vast, with rich wind energy resources and great development potential. In terms of cost, as the water depth increases, the amount of fixed foundation materials increases, the construction difficulty increases, and the operation and maintenance cost increases. It is generally believed that floating wind power will be more suitable after the water depth exceeds 60m. In addition, the deep sea area is vast, and floating wind turbines can be built into large-scale wind farms with better economy. At the same time, the installation form and location of floating wind turbines are more flexible, which can effectively reduce noise, electromagnetic waves and other hazards. Floating wind power can utilize the existing infrastructure and supply chain capabilities of the offshore oil and gas industry, which can effectively reduce costs. Most importantly, floating offshore wind farms provide the possibility of further expanding the power and size of the wind turbines used, which helps to reduce the final cost of electricity per kilowatt-hour.
