The current wind power generation is only second to the hydroelectric power generation and already accounts for 16 percent of the power generation amount of global renewable resources. Offshore wind power has become one of the important sources of renewable energy power in the context of global high concern about developing low-carbon economy. In a coastal region with dense population, a gigawatt-level offshore wind farm can be quickly established, so that offshore wind power can become one of important technologies for reducing carbon emission in the energy production link in an economic and effective mode. Although the offshore wind power starts late, the offshore wind power is rapidly developed all over the world in recent years by virtue of the characteristics of stability of sea wind resources and large power generation power, has the characteristic of being highly dependent on technical drive, and has the condition of serving as a core power supply to promote the development of global low-carbon economy in the future.
