Problems solved by technology

[0002] The international research and development of offshore wind power began in the 1990s. After more than ten years of development, offshore wind power technology is becoming more mature and has begun to enter the stage of large-scale development. Compared with land wind power, the development of offshore wind power has the following major advantages: Advantages, high power generation, stable power, long running time, less environmental restrictions, offshore wind power has broad market prospects, attracting more and more manufacturers to join, but the long-term high cost and technical difficulties have also restricted Its development, the current existing technology has the problems of complicated maintenance and overhaul, the need for wind control devices, and the complicated blades and high manufacturing costs
