The objective of this paper is to present the methodology for the application of Reliability Centered Maintenance to wind turbines. The reliability and maintenance of wind turbines is a growing area of interest. The inherent variation in the loading experienced by wind turbines presents unique problems that differ from current practice within the power generation sector. The core of these issues center on the inherent variability of the wind and the resulting loads transferred to the equipment. Reliability Centered Maintenance (RCM) is a useful tool that provides the means to overcome some of these difficulties. RCM is implemented through either Condition Based Maintenance (CBM) or Time-Directed Maintenance (TDM). CBM is implemented through the use of condition monitoring based on defined condition indicators established through field experience, or laboratory testing. TDM is implemented through the use of reliability failure analysis to characterize a time directed maintenance interval. This failure analysis is performed on either laboratory test specimens, or failed field components. This paper presents the methodology for applying CBM or TDM to a wind turbine as well as suggestions for scaled laboratory testing.
