Since offshore wind turbine supporting structures are subjected to dynamic environments with time-varying loading conditions, it is important to model their dynamic behaviour and validate these models by means of vibrational experiments. In this paper, dynamical state assessment of the supporting structure is investigated by experimental modal analysis. In particular, it will be demonstrated that the experimental modal analysis can be an useful technique for the damage detection in the tripod supporting structure of an offshore wind turbine.

Abstract
Since offshore wind turbine supporting structures are subjected to dynamic environments with time-varying loading conditions, it is important to model their dynamic behaviour and validate these models by means of vibrational experiments. In this paper, dynamical state assessment of the supporting structure is investigated by experimental modal analysis. In particular, it will be demonstrated that the experimental modal analysis can be an useful technique for the damage detection in the tripod supporting structure of an offshore wind turbine.File in questo prodotto:
