摘　　要：通过浪向角分析确定环境条件,应用商用软件对单点系泊FPSO进行运动性能计算分析,评估FPSO的耐波性并为FPSO提供设计依据。首先采用静态分析方法,计算在不同风、浪、流组合下FPSO艏向和浪向之间的夹角与有义波高的关系,给出有义波高相对于夹角的包络线,并根据此包络线确定运动性能分析的环境条件;其次,介绍船体横摇运动的阻尼成分以及阻尼的估算方法,并采用三维线性势流理论计算船体运动的RAO;最后,对某型单点系泊FPSO进行浪向角和运动性能的实例分析,评估该型FPSO的耐波性。Environmental condition determined by wave heading analysis has been used for the motion analysis of a single point mooring FPSO by commercial software in order to evaluate its seakeeping performance and provide design basis.Based on the static analysis method,it calculates the relationship between significant wave height and included the angle between ship heading and wave direction under the different combination of wind,wave and current.It provides the contour of the significant wave height relative to the included angle for the determination of environmental condition of motion analysis.Secondly,it introduces the roll damping component and its evaluation method,and calculates RAO of ship motion by 3D linear potential theory.Finally,it analyzes the heading angle and motion performance of a single-point-mooring FPSO,and evaluates its seakeeping performance.
