Suitable failure statistics as a key for improving availability

摘要

Like in most other areas the maintenance optimisation also gains importance in the wind energy sector. A suitable failure statistic can enables a significant reduction of maintenance costs in combination with an improved availability. The findings about necessary data, data base structure and on characteristic reliability indicators as well as an overview about options for improving availability will be presented in this paper. Furthermore, an outlook about gathering and evaluating future operational experiences of offshore wind farms will be given.
