摘　　要：应用三维势流理论及非线性时域耦合分析方法,研究了西非海域单独风浪、涌浪环境条件对多点系泊FPSO水动力性能的影响。结果表明低频响应中涌浪、风浪占据同等重要地位,波频响应中涌浪占据主导地位,且涌浪入射角度对系缆张力有显著影响。因此在西非海域进行FPSO等浮式结构物水动力性能的研究时,必须考虑风浪和涌浪同时存在的情况。本文的研究为西非海域浮式结构物水动力性能分析提供了有益参考。Based on 3D potential theory and non-linear time domain coupled analysis, the influence of swell and wind-sea on hydrodynamic performances of FPSO in West Africa waters are investigated respectively. It can be concluded that swell and wind-sea have significant effect in low frequency response and cable force, but swell has main effect in high frequency response. It is necessary to consider swell together with wind-sea in the study of hydrodynamic performances of FPSO. That offers an important reference on hydrodynamic performances analysis of FPSO in West Africa waters.
