The present paper shows the importance of wind turbine availability on an offshore wind farm and how this availability relies on three factors: wind turbine systems reliability, systems maintainability and efficiency of logistics activity. The paper deals with all identified factors that contribute to the availability of the offshore wind farm and determines their relative importance based on the Analytical Hierarchy Process (AHP). The proposed methodology can be used and adapted for each specific situation taking into operational and maintenance data, wind farm location (shore distance), water depth, site accessibility (vessels and crew), weather dependence (meteorological and oceanographic factors), opportunistic maintenance, spare parts and other related factors. The results show the most important factors and their weight, supporting the decision making process and allowing increasing offshore wind farm availability.
