摘　　要：南海海域海洋环境条件十分恶劣,FDPSO采用何种定位方式保证其正常作业是一个值得探讨的课题。文章采用数值计算和模型试验的方法,对单点系泊FDPSO水动力性能开展研究。数值计算包括频域水动力性能计算和时域船体/锚链耦合数值分析。频域水动力性能计算得到FDPSO船体水动力系数、波浪力和运动幅值响应算子。时域耦合数值分析计算了单点系泊FDPSO在南海海域一年一遇海况和百年一遇海况下的运动特性。模型试验在上海交通大学海洋工程深水池中进行,包括静水衰减试验、白噪声试验和不规则波试验。数值计算结果和模型试验结果比较,验证了数值计算方法的可靠性,并研究了单点系泊FDPSO在南海海域作业海况和极限海况的水动力特性。Because the environment condition of the South China Sea is very severe, the position system of FDPSO is a topic worthy of study. In this paper, numerical method and model test are adopted to investi-gate the hydrodynamic performance of FDPSO with single point mooring system. Frequency domain method and time domain coupled analysis are involved in the numerical calculation. The hydrodynamic coefficients, wave exciting force and response amplitude operator are obtained from the frequency domain analysis. The motion character of FDPSO in one-year and a hundred year return period sea states of the South China Sea are acquired by time domain coupled method. The model tests are carried out in the Deepwater Offshore Basin in Shanghai Jiao Tong University, which are composed of free decay tests, white noise tests and irreg-ular wave tests. The numerical results are compared with the test results to verify the numerical model. The hydrodynamic performance of FDPSO with single point mooring system in operating condition and extreme condition of the South China Sea are studied.
