摘要
对浮式储存及再气化装置(FSRU)-液化天然气船(LNGC)多浮体系泊系统在风、浪、流联合作用下的水动力响应进行研究。提出一种多浮体系泊系统旁靠作业的布置方式,通过数值模拟得到风、浪、流联合作用下该系统六自由度运动及相对运动、缆绳张力和护舷受力的响应时程,分析给出连接缆绳预张力对船舶运动响应、缆绳张力和护舷受力的影响规律。结果表明,该布置方式可满足选择的环境载荷使用要求,所采用的数值模拟方法对同类多浮体系泊系统运动分析有参考意义。
The hydrodynamic response of FSRU-LNGC multi floating mooring system under the combined influence of wind, wave and flow is studied. A layout scheme of multi floating mooring system’s side-by-side operation is proposed. The motion response time history of the system’s six degrees of freedom motion, relative motion, cable tension and fender force under the combined influence of wind, wave and flow is obtained by numerical simulation. The influence of pre-tension of the connecting cables on ship’s motion response, cable tension and the fender force is analyzed and given. The results indicate that the layout scheme can meet the requirements of use under the selected environmental load, and the adopted numerical simulation method has reference significance for the motion analysis of similar multi floating mooring systems.
