| Abstract: |
The structural components of wind turbines (WT) are currently designed for a service life of 20 years only and the limiting criterion is the fatigue safety with respect to the fatigue loading generated by the wind. However, effective fatigue loading endured by the tower and foundation could be much lower than the theoretical fatigue loading provided by codes, mainly because wind conditions are likely to be below the design assumptions. In order to extend the service life of the structural components of wind turbines, site‐related wind conditions and their actions of structural components should be measured on existing WTs. The method described in this paper proposes a long‐term monitoring that will allow owner to extend the service life of their wind turbines. |
