Land fans are more optimally designed for noise reduction, while offshore fans are optimized for greater aerodynamic efficiency, and high tip speed, small blade area will bring some design advantages to the fan structure and drive train. Offshore wind power is superior to onshore wind power in aspects of power generation stability, power grid access convenience, land conservation and the like, and the development of the offshore wind power industry has great potential.
