摘　　要：本文以某型最大作业水深2300 m的深海半潜式平台为研究对象,采用计算速度较快的频域动态分析方法与多目标优化算法相结合,对其16点锚泊定位系统的定位性能进行分析,并在现有锚泊系统配置的基础上,对锚泊系统的水下布置方案进行优化设计。通过命令流实现锚泊定位系统设计方案的大范围寻优和多目标优化,并对设计参数进行自动更新与组合,判断各参数间的相关性,驱动优化目标不断改良,找到更佳的锚泊定位系统设计方案。The positioning performance of a deepwater semi-submersible platform working at a depth of 2300 m with a 16-mooring-lined system was analyzed in this paper.Based on frequency-domain dynamic analysis method and multi-objective optimization algorithm NSEA+,large-scale search and multi-objective optimization were realized by use of the command stream in mooring system underwater arrangement design while the reconfiguration of the mooring system optimization design was carried out through automatic update and combination of the design parameters,judgment of the correlation among various parameters and continuous improvement of the optimization objectives.
