摘　　要：以半潜船装载钻井平台为实例，建立半潜船在风浪联合作用下的数学模型，利用PM和双参数海浪波能谱分别计算不同条件下船舶最大横摇角度，依据数学模型计算出潜装作业的初稳性高度限值，从而对比分析出本次半潜船绑扎系固的安全风速。在船舶作业相关规范的前提下，为本次半潜船作业提供气象参考，使船舶设备、作业人员以及决策者有相应的准备，保证作业的顺利进行。Taking the semi-submersible vessel loading drilling platform as an example, the model of semi-submersible vessel in wind and waves was established. The PM and double parameter ocean wave energy spectrum was used to calculate the maxi- mum rolling angle and the metacentric height limit of ship under different conditions, so as to get the safe wind-speed of semisubmersible vessel. On the premise of the relevant regulations of ship operation, the method can provide the meteorological refer- ence for the semi-submersible ship operation, make the ship equipment, operators and decision makers prepare accordingly, and ensure the smooth operation of the operation.
