Integrated preventive–proactive–reactive offshore wind farms maintenance planning

By integrating preventive, proactive, and reactive maintenance strategies, offshore wind farm (OWF) operators can ensure that wind turbines (WT) can operate as much as possible, thereby maximizing energy production while only slightly increasing maintenance costs. This three-stage driven approach aims to reduce the number of unplanned maintenance activities that crews must undertake in potentially challenging offshore conditions, extend the lifespan of equipment, and minimize operational costs while ensuring a safe and sustainable energy production process. To enable the analysis of these mutually conditioned expectations, a reference model is proposed that integrates the components of the wind farm maintenance chain in their life cycle. This model allows for a precise formulation of the problems that constitute the above-mentioned challenges. The adopted declarative representation guarantees both the openness of the model structure and the use of commercially available constraints programming environments for implementation and solution generation. The possibilities of using the model to evaluate selected variants of the wind farm maintenance strategy are illustrated by the results of the attached computer experiments.
