摘　　要：根据FPSO环境烈度因子的计算方法和实际应用情况调整基于油船设计规范的FPSO计算,采用基于三维线性势流理论的直接计算法和波浪谱分析方法对FPSO环境烈度因子计算所涉及的动载荷极值预报和首向分析等关键因素进行分析探讨,给出具体的解释和规定,计算实例表明,应用环境烈度因子可以合理考虑FPSO作业环境的特殊性,使设计评估结果更为准确。The calculation method and practical application of FPSO environmental severity factors （ESF） is studied, in order to adjust the FPSO calculation methods based on the oil tanker rules. Using direct computation method based on 3D linear potential flow theory and wave spectrum analysis, the key factors is analyzed related to the calculation of FPSO ESF, such as prediction of wave load extreme values and heading analysis. Through the real case, it indicates that the application of ESF takes the particularity of FPSO working environment into account and makes the results of design more accurate.
