FLNG系统旁靠外输作业时的水动力性能数值研究

对大型浮式液化天然气(FLNG)系统与LNG运输船以旁靠方式进行LNG外输作业时船体的水动力性能开展数值研究。全面考虑了双船体之间的水动力相互干扰,以及船体与系泊系统和连接系统之间的耦合作用。在验证了数值计算模型正确性的基础上,对旁靠外输作业时各典型工况进行数值计算,从而得到在风、浪、流共同作用下FLNG与LNG运输船间的相对运动情况、系泊系统和两船之间连接系统的受力情况,为后续设计提供参考。

A Numerical Study of the Hydrodynamics of a FLNG-LNG Carrier System during Side-by-side Offloading Operation

This paper introduces the hydrodynamics of a FLNG-LNG carrier system during side-by-side offloading operation with numerical method. The coupled hydrodynamics of the multiple bodies and the coupled effects of ship motion and mooring system were considered seriously in this study. Several typical load conditions were calculated based on the verified of the numerical model to obtain the relative motion responses between the FLNG and the LNG carrier under the combination of the wind, current and waves, together with the loads acting on the mooring system and the connection system.
