Abstract

Jacket substructures for offshore wind turbines prove to hold a high level of fatigue. The fatigue performance of welded connections is considered to be design driving. Since measurements on all these joints are not practicable the possibility of predicting stress is essential in order to estimate fatigue life for jackets.
Within this study a transfer of MDE (The Modal Decomposition and Expansion) from monopile support structures, to which this response estimation method is already applied, to jacket substructures is done. This is performed by the introduction of mixed mode shapes. It can be shown, that knowledge of the first two mode shapes is sufficient to predict stress history accurately with a limited set of sensors.
