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。
通過浪嚮角分析確定環境條件，應用商用軟件對單點繫泊 FPSO 進行運動性能計算分析，評估 FPSO 的耐波性併為 FPSO 提供設計依據。首先採用靜態分析方法，計算在不同風、浪、流組閤下 FPSO 艏嚮和浪嚮之間的夾角與有義波高的關繫，給齣有義波高相對于夾角的包絡線，併根據此包絡線確定運動性能分析的環境條件；其次，介紹船體橫搖運動的阻尼成分以及阻尼的估算方法，併採用三維線性勢流理論計算船體運動的 RAO ；最後，對某型單點繫泊 FPSO 進行浪嚮角和運動性能的實例分析，評估該型 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.
