Current,the global energy is transforming from a fossil energy system to a low-carbon energy system dominated by new and renewable sources of energy.Offshore wind power has become an important area of development in some countries.During the"14th Five-Year Plan"in Hainan Province,it is expected to to build 11 offshore wind farms along the coast with an offshore wind power capacity of 35 million kW as the medium and long-term planning.The cycle for offshore wind power construction and production is usually long,involving multiple offshore projects,and has high potential safety risks.This paper mainly analyzes the navigation,construction operation,environmental safety risk as well as the prevention and control brought forth by the offshore wind power projects.
