An analysis is presented of the vertical bending moments induced in a containership by a set of abnormal waves measured at
different locations and on different occasions. A systematic investigation was carried out by using a large set of wave traces
that included abnormal waves. In this way it was possible to assess the influence of the height, length, and shape of the
abnormal waves on the wave-induced structural loads. The probability distributions of the ship responses to the sea states
that included the abnormal waves were also calculated and were compared to the responses induced by the abnormal waves and
to fitted distributions. Finally, the structural loads induced by the abnormal waves were compared with rule values and with
long-term predictions. 相似文献
