摘　　要：目前半潜船尾部线型设计主要分为尾支架式和双尾鳍式两种型式。针对上述两种尾部线型型式,以9万吨级大型半潜船为例,从快速性、动力定位能力、航向稳定性以及轴系安全等方面开展研究,对两种尾部线型的优缺点进行分析比较。研究结果表明,双尾鳍型式的尾部线型对于快速性、航向稳定性和轴系安全比较有利,而尾支架型式则在动力定位方面有更好的表现。The current stern type design of semi-submersible vessels can be divided into two main types:tail bracket type and twin skeg type.Using a 90000 tonnes semi-submersible vessel as an example,this paper analyzes the performance of hull speed,dynamic positioning ability,course stability,and shafting safety.The results show that the twin skeg type improves the hull speed,course stability,and shafting safety.In contrast,the tail bracket type performs better in dynamic positioning capacity.
