摘　　要：针对FLNG关键技术的并靠外输问题,本文基于频域波浪势流理论建立FLNG单体和FLNG-LNGC双体水动力模型,并且结合上海交通大学水池模型实验和经典文献结果验证了数值算法的准确性。在此基础上,深入讨论了FLNG并靠外输系统单浮体水动力特性和双浮体的耦合作用。进一步通过改变系统参数(间距、装载状态、波浪入射方向和水面阻尼)建立不同的并靠外输模型进行参数敏感性分析,并且对FLNG-LNGC双船间水体共振规律进行探索。For the side-by-side offloading problem of FLNG,hydrodynamic models of a single FLNG and an FLNG-LNGC based on wave potential theory in frequency domain are created in this paper.With the data of experiments compared with those of classic literatures,the accuracy of the numerical method in this paper is validated,based on which the hydrodynamic characteristics of the single FLNG and the FLNG-LNGC during side-by-side offloading operation are analyzed.Finally,by further changing the parameters of the side-byside offloading system(such as distance,loading conditions,wave directions,viscous damping of free surface and so on),the resonance phenomenon of interactive hydrodynamics is detailedly discussed.
