Abstract | Fatigue life is a design driver for the foundations of offshore wind turbines. Monitoring the consumption of fatigue life is thus an essential part in a full-scope structural health monitoring strategy for offshore wind turbines. This contribution will feature the structural health monitoring data from three offshore turbines in the Belgian North Sea. All three turbines are instrumented with strain gauges and accelerometers. Our interests lie with the interaction between environmental, operational conditions and the fatigue life consumption. For instance we will analyze how different EOCs, changes in the wind direction and structural properties such as the tower resonance frequencies affect fatigue life and thus ultimately structural integrity over its lifetime. |
