由于中国南海海域海况十分恶劣,浮式钻井生产储油轮(FDPSO,Floating,Drilling,Production,Storage and Offloading vessel)定位方式的研究是海洋工程界值得关注的课题.文章采用数值模拟和模型试验的方法对多点系泊FDPSO水动力性能开展研究.数值模拟包括FDPSO船体频域水动力性能计算和船体/锚链时域耦合分析.船体频域水动力性能计算得到了水动力系数,波浪力和运动幅值响应算子；时域耦合数值分析得到了中国南海海域一年一遇海况和百年一遇海况下船体六自由度运动时历.模型试验在上海交通大学海洋工程深水池开展,包括静水衰减试验,白噪声试验和不规则波试验.对数值计算结果和模型试验结果进行了比较,验证了数值结果的准确性,并对多点系泊FDPSO在中国南海海域的水动力性能进行了研究.

Because the environment condition of the South China Sea is very severe,the position system of FDPSO is a worthy topic of studying.In this study,numerical method and model test are adopted to investigate the hydrodynamic performance of FDPSO with spreading 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 at Shanghai Jiao Tong University,which are composed of free decay tests,white noise tests and irregular wave tests.The numerical results are compared with the test results to verify the numerical model.The hydrodynamic performance of FDPSO with spreading mooring system in operating condition and extreme condition of the South China Sea are studied.
