摘　　要：当前已建成的半潜式起重船数量较少,此类型船的设计研发没有完备的母型船资料可供参考。为此,以某半潜式起重船为研究对象,阐述其结构设计特点,并对结构设计中需注意的几个关键问题进行分析,包括中横剖面、骨材间距和设计温度对结构钢级的要求,以及波浪载荷预报和有限元计算等。在此基础上,给出此类型船结构设计分析方面的建议,为同类型船的结构设计提供参考。Only small number of semi-submersible crane vessels have been built until now,and learning from those designs could be of great value for new developments.This paper elaborates structure design characteristics of a semi-submersible crane vessel,and analyzes the key points in the structural design,such as midship section structure,stiffener spacing,material selection for low temperature,wave load prediction,and finite element analysis.Several suggestions for rationalizing the structure design are presented.The proposed method of structure design can provide reference for designing vessels of similar type.
