Abstract
Modern wind turbines achieve a quite high availability of more than 95%. Nevertheless, quite a number of faults cause unscheduled down times up to ten per year, resulting in high maintenance efforts, production losses and costs. However, the common way of documenting faults and maintenance activities manually in paper form is currently not suitable for standardised and automated statistical evaluations. Therefore operational experience can seldom be used to improve design and maintenance procedures. For that reason a consortium of owners, operators, services-providers and researchers exploit experience with WT operation more intensively. The focus is on proposals for standardising data acquisition, data transmission and on a library for characteristic reliability values. Objective is to allow statistical analyses of reliability characteristics of wind turbines and subassemblies.
