Abstract: Based on the characteristics of offshore wind power operation and maintenance in China, this paper analyzes the current situation and development trend of offshore wind power operation and maintenance technology and equipment in China. Taking an offshore wind farm in the South China Sea as a research scenario, this paper proposes a vibration monitoring scheme for offshore wind turbine system, an offshore wind turbine boarding scheme, an offshore wind turbine maintenance and operation and maintenance scheme, and an offshore wind farm inspection scheme, which puts forward guiding significance for the operation and maintenance of offshore wind farms in China.

Key words: offshore wind power, operation and maintenance, vibration monitoring, operation and maintenance ships, operation and maintenance strategy
