摘　　要：利用水动力分析软件HydroSTAR和锚系泊软件Ariane7,对LNG浮式储存及再气化装置(LNG-FSRU)和穿梭LNG船(Shuttle-LNG)组成的多浮体系统在并靠外输作业时的水动力性能进行分析研究。重点对单船和并靠下的RAO曲线进行了对比;在一定环境组合下考虑水动力相互干扰的因素,对多浮体系统进行了时域分析,得到了此海况下的船体运动、相对运动、两船之间系泊缆张力以及护舷反力等的特性,可为装卸臂的设计和实际工程应用提供相关技术依据。The hydrodynamics of a Liquefied Natural Gas Floating Storage Regasification Unit（LNG-FSRU）in side-by-side offloading operation with a shuttle LNG carrier are calculated by means of professional software HydroSTAR and Ariane 7.The RAO curves for the ship itself and the curves for the combination of offloading operation are examined.The time domain analysis is conducted on the system of floating objects with hydrodynamic interaction between the structures inside the system to find the ship motion,relative motion between structures,mooring force between two vessels,and reaction force of fender.This study can be the guideline for the design of loading arm and other practical applications.
