[0002] Offshore wind turbines have large single-unit capacity, poor accessibility, harsh operating environment, high maintenance costs, and large economic losses caused by downtime

At present, the fault maintenance mode of offshore wind turbines mainly draws on the experience of onshore wind power, and a process control mechanism suitable for the maintenance of offshore wind turbines has not yet been formed; at the same time, after the failure of offshore wind turbine equipment, the maintenance mode adopted is often a single defect elimination , did not optimize the overall process, leading to problems such as increased downtime, increased personnel costs and transportation costs, and low maintenance efficiency
