| Abstract: | A survey is presented of the generally used theories for predicting wave-induced motions and loads on ships as well as of the available comparisons with experimental results. The published results are used to quantify a model uncertainty factor that is proposed here to correct the theoretic predictions for systematic deviations and to quantify their uncertainty. The non-linearity of the response is also considered and modelled. A formulation is developed to quantify the influence of the transfer function uncertainty on the short-term response variance. |
