摘　　要：对抑制半潜式平台垂荡响应提出了两种解决方案。在没有系缆力作用的情况下,借助于吃水深度对垂荡响应幅值影响的理论研究,利用SESAM/HydroD软件进行数值计算,得到吃水深度增加对平台垂荡幅值的抑制规律。在有系缆力作用的情况下,考虑采用配置质量块的方法降低平台垂荡响应。用SESAM/DeepC软件进行时域分析,得到质量块抑制平台垂荡的规律。结果表明,两种方法对垂荡响应均有比较有效的抑制作用。Two kinds of solution to restrain the heave amplitude were put forward.Without considering the mooring force,on the basis of discussing the theoretical relationship between the draft and the heave amplitude,a numerical calculation with the Sesam/HydroD was made and the effect of the draft to the heave amplitude was obtained.With the mooring force,added mass block on the mooring line was taken to restrain the heave amplitude,and a time domain analysis was made with the Sesam/DeepC,to obtained the rule between the quality of the mass block and the heave amplitude.The results showed that these two methods are effective to restrain the heave amplitude.
