| 摘 要： | 采用数值分析软件Sesam/HydroD对某半潜式起重船在航行状态和起重作业状态下的波浪载荷进行长期预报和短期预报.在航行状态下,预报得到的最大波浪弯矩和剪力分别为规范值的1.4倍和2.0倍,用于进行结构疲劳评估(超越概率为10-2)的波浪弯矩最大预报值约为用于进行结构强度评估(超越概率为10-8)的波浪弯矩最大预报值...

| Abstract: | The software Sesam/HydroD is used to calculate the wave load on a semi-submersible crane vessel in sailing and in lifting operation.Both long-term prediction and short-term prediction are performed.In sailing condition,the predictions for the calculated maximum wave bending moment/shear force are about 1.4/2.0 times as much as those given by the standard recommended empirical formula.The maximum wave bending moment used in fatigue assessment(10-2 probability of exceedance)is about 20%of that in strength assessment(10-8 probability of exceedance).The calculated maximum wave bending moment in lifting operation is about 15%of that in sailing. |
