摘要
对一工作水深为375m的中等水深FPSO系统的水动力性能进行了模型试验研究和数值计算。采用了混合模型试验技术进行等效水深截断系泊系统的模型试验并在时域中进行了数值重构计算。对试验和数值重构计算得出的水动力响应的统计值、功率谱和RAO等进行了比较,结果显示两者符合得很好。最后,对全水深实际系泊系统的FPSO进行了时域数值模拟计算,预报了该FPSO系统在几种环境条件下的水动力响应情况。
The experimental study hased on hybrid model test technique and numcrical reconstruction in time domain Oll the hydrodynamic performance of a turret moored FPSO in water depth of 375m were cartied out.The calculated and measured results were analyzed and compared for the statistical characteristics, spectrum,and RAO （Response Amplitude Operator） of the hydrodynamic response.The agreement between the, calculation arid the model test was good. Finally, the hydrodynamic response of the FPSO with fulldepth mooring system under several environments was predieted,
