ECN is developing the Flight Leader model, which is based on a concept with which the accumulated mechanical loading of all turbines in an offshore wind farm can be estimated at acceptable costs. This information can be used to optimise and lower the cost of Operation & Maintenance (O&M), for example by prioritising inspections and replacements. In this paper the background and general concept of the Flight Leader model are presented. Key to the application of the Flight Leader concept are the relations between standard (SCADA) signals and load indicators. The more accurate these relations, the more reliable are the calculations of accumulated loading. Using measurements from ECN’s EWTW wind farm it will be shown how artificial neural network (ANN) techniques can be used for accurately estimating load indicators using only 10-minute statistics of standard SCADA parameters.
