由于双体船稳性和操纵性较优等特点，近年来备受关注，被广泛应用于军事和民用船舶领域。采用铝合金建造的船舶具有结构重量轻、耐腐蚀等优点，被主要运用于观光船和快艇等小型船舶。以19.88 m双体铝合金风电运维船为研究对象，设计了纵骨架式和全横骨架式2种结构型式方案，建立整船有限元模型，对其施加约束和载荷，进行总强度分析；根据双体船各部位的应力分布规律，对连接桥结构进行方案调整及分析。最终给出双体铝合金风电运维船合理的结构设计方案，为推广发展双体风电运维船提供技术支撑。
Due to its large deck area and good stability and maneuverability, catamarans have attracted much attention in recent years, and have been widely used in military and civil ship fields. Ships made of aluminum alloy have the advantages of light weight and corrosion resistance, and are mainly used in small ships such as sightseeing ships and speed boats. Taking the 19.88 m twin-body aluminum alloy wind power operation and maintenance ship as the research object, two structural type schemes of longitudinal skeleton type and full transverse skeleton type were designed, and the whole ship finite element model was established. Constraints and loads were applied to it, and the total strength analysis was performed; Summarize the stress distribution characteristics of various parts of the catamaran, adjust and analyze the scheme of the connecting bridge structure, and finally give a reasonable structural design plan for the catamaran wind power operation and maintenance ship to provide technical support for the promotion and development of the catamaran wind power operation and maintenance ship.
