Objective In order to solve the problem of difficult operation and maintenance of offshore wind farms, the intelligent maintenance and repair platform is proposed.

Method The platform was created by applying intelligent inspection (pressure station patrol robot, drone patrol), automatic intelligent maintenance (wind bolt fastening robot, wind turbine anti-corrosion spraying robot, maintenance decision-making), operation supervision (intelligent access control, visual helmet), intelligent operation and maintenance scheduling and training services.

Result The problem can be solved with the shortage of offshore wind farm operation and maintenance resources, backward offshore wind power operation and maintenance technology, poor accessibility of offshore wind farms, high cost of offshore wind power operation and maintenance, lack of standards and specifications in the offshore wind power operation and maintenance industry, lack of professionals and other related operation and maintenance pain points. Taking the inspection of the main transformer at the offshore station and the anti-corrosion coating of wind turbines as examples, the two aspects are analyzed , including the intelligent inspection and maintenance decision table of the offshore station robot, as well as the specific scheme analysis of the anti-corrosion and rust removal robot for wind turbines.

Conclusion Therefore, it can improve the intelligent level of operation and maintenance of offshore wind farms, reduce operation and maintenance costs, reduce costs and increases efficiency, and is expected to be applied and promoted in engineering.
