采用数值计算方法研究FLNG尾输过程的动力特性。根据中场理论计算FLNG与LNG运输船的耦合水动力，并建立包括FLNG和LNG运输船、单点系泊系统以及外输定位缆绳的耦合分析模型进行运动求解。结果表明，在FLNG尾输过程中，可能将发生耦合水动力效应，而非耦合的水动力模型将将高估作用于两船体特别是LNG运输船上的波浪漂移力。风与海流有助于提升整体系统的稳定性，并而降低两船碰撞的风险。
The dynamic characteristics of FLNG are studied during tandem offloading operation by using numerical method. The coupled hydrodynamic results of FLNG and LNG carrier are calculated according to the middle field theory, and the coupled model include FLNG, LNG carrier, single point mooring system and hawser lines is established and the responses are obtained. The result shows that during the tandem offloading process of FLNG, the coupled hydrodynamic effects will occur and the no-coupled hydrodynamic model will overestimate the drift force acting on the two vessels especially for LNG carrier. The wind and current can improve the stability of the whole system and reduce the risk of collision.
