To address the intricate challenge of scheduling optimization for maintenance tasks in offshore wind farms
an innovative optimization model for offshore wind turbine O&M scheduling and an enhanced genetic algorithm
termed Optimized Genetic Algorithm (OPGA)
were introduced. This model takes into account the workload and operational efficiency of the maintenance teams
incorporates a strategic approach for task-turbine grouping
and refines the sequence and route of maintenance activities with the aim of reducing maintenance costs and enhancing operational productivity. The model's constraints encompass the maintenance vessel's load capacity and travel distance
the team's working time constraints
among others. In order to augment the accuracy and efficiency of the model
the OPGA algorithm employs non-repeating natural-number encoding to depict the sequence and path of maintenance operations
integratesa branch-and-bound search within the decoding phase
and incorporates a population-catastrophe operator. The experimental results based on an offshore wind farm project show that compared with the traditional genetic algorithm
OPGA can save more than 15% of the operation and maintenance cost and increase the working hour utilization rate by more than 10% when solving largescale problems.
