Abstract

The paper addresses the calculation of extreme motion of a TLP type of floater for an offshore wind turbine. Motions are of significant importance for the operation of the wind turbine as they influence the blade loadings and hence the downtime of the wind turbine energy production. The paper illustrates that a very effective, stochastic response analysis can be performed using the First-order reliability method (FORM), well-known within structural reliability. The results presented are the mean outcrossing rates of the horizontal motions, from where extreme value predictions are readily obtained. In the calculation the forces on the floater are derived from Morison’s equation, taking into account the motion of the floater.
