The development of offshore wind power is of great strategic significance, so it should pay high attention and strength support; the development of offshore wind power is facing a serious challenge and it should be scientifically dealt with avoiding impulsive rash advance. To China's offshore wind power development, we must uphold the scientific development philosophy, the rational and orderly development of the high starting point, and the sustainable and leaping development with combination of innovation and unique features.The cost, benefit and risk restric the development of offshore wind. But through the progress of science and technology, mastering the key technology of wind power, and improving the planning and construction ability, we can effectively resolve the major factors that restrict the development to ensure the healthy development of offshore wind power. In view of the sound and rapid development of offshore wind power, to build high-quality and high effective offshore wind farm, some advice was given.
