Estimation of nonlinear long-term extremes of hull girder loads in ships

摘要

This paper deals with a estimation of long-term extreme value for a given return period, say D = 100yr. In principle, this response is obtained by combining the response in all the sea States. The long-term response for a linear system can be effectively obtained by determining the Response for each sea state, specified by the significant wave height, Hs, and the peak period, Tp, In the frequency domain. However, if the response is nonlinear, time domain simulation and A long time series would be required, to limit statistical uncertainty.
