浮式液化天然气生产储卸装置(Floating Liquefi ed Natural Gas System,FLNG)作为一种新型的天然气开发平台,其理论研究已成为海洋工程领域的研究热点。基于该装置的基本组成,重点阐述其在海域作业时容易产生的几种水动力响应问题,包括多浮体(FLNG与LNG运输船)间耦合的水动力、液舱晃荡对FLNG的影响、船体与系泊系统耦合的水动力、单点系泊FLNG水平面的稳定性等,梳理了国内外研究者针对该装置相关技术的研究成果,提出了对该装置安装动力定位系统,将模型与数值模拟相结合的研究方法,从而为今后针对FLNG相关技术的深入研究提供了理论参考和技术支持。
Floating Liquefied Natural Gas System (FLNG), as a new kind of natural gas development platform, has become a hot research topic in the field of marine engineering. Based on the basic composition of the device, several problems of hydrodynamic response easily occur when operating in the sea area, including the hydrodynamic coupling between multi-floating body (FLNG and LNG carrier), the influence of tank sloshing on FLNG, And the stability of the single-point mooring FLNG water level coupled with the mooring system, combing the research results of researchers at home and abroad for the related technology of the device, put forward to install the dynamic positioning system of the device, the model and the numerical simulation phase Combined research methods, which will provide theoretical reference and technical support for further research on FLNG related technologies in the future.
