Abstract:
A method is proposed for the long-term formulation of wave induced vertical bending moments in ship structures. The non-linearity of the response is represented by an uncertain modelling factor that is calibrated by experimental values. Long term predictions are obtained for a tanker and a container ship hull showing that only in the latter case is the response clearly non-linear and reproduced in the long-term predictions.
