Introduction  Aiming at the operation & maintenance and safety management of offshore wind farm， the intelligent operation and maintenance management system for offshore wind farms is proposed.

  Method  Through the intelligent dispatching system of offshore wind power， multi-source tracking and boundary warning system of offshore wind power radar， and operation supervision system of offshore wind farm wind turbine platform， the intelligent operation and maintenance management system of offshore wind farm was built.

  Result  Through the offshore wind power intelligent dispatching system of the onshore centralized control center， personnel safety management and ship dispatching can be realized. Through the offshore wind power radar multi-source tracking and boundary warning system， the full-range tracking of ships in the ocean area is realized， and the safety of the wind turbines and submarine cables of the offshore wind farm can be ensured. Through the wind turbine platform's offshore wind farm fan platform operation supervision system， the comprehensive management of wind turbine operators on the wind turbine platform can be assured.

  Conclusion  Therefore， it can realize the overall management of personnel， ships and wind turbines in offshore wind farms， it effectively ensures the safety management of personnel and ship scheduling， improves the safety of wind turbines and submarine cables of offshore wind farms， and realizes the intelligent operation and maintenance efficiency of offshore wind farms， which is expected to be applied and promoted in the project.
