渤海海域软刚臂系泊核动力平台水动力分析

Hydrodynamic investigation ofnuclear power platform moored with yokein bohai sea area

我国首座海洋核动力平台采用船型方案,由塔架软钢臂单点系泊装置系泊,作业海域为渤海海域。为确保海洋核动力平台安全和核安全,在设计阶段采用模型试验和数值计算对其进行水动力分析必不可少。本文首先得到在单位波幅规则波下频域RAO,然后计算在风浪流联合作用下的时域运动响应,并采用Weibull分布对垂荡、横摇和纵摇的时历运动进行统计。最后,将平台运动特性的数值计算结果与试验数据进行对比分析,为海洋核动力平台的设计提供参考。

The first marine nuclear power platform in China uses ship type, moored with yoke mooring system,and working in the Bohai Sea.In order to ensure the marine nuclear power platform securityand nuclear safety,it is necessary to use both model test and numerical calculation to analyze and compare the hydrodynamic performance of it. In this paper, we first obtain the frequency-domain RAO inregular waves of unit amplitude, and then calculate the time-domain motion response under the combined effect of wind, wave and current loads.Weibull distribution is also used to calculate the heave,roll and pitch motion. Finally, the numerical calculation results and model test results are compared and analyzed to provide the design reference for the marine nuclear power platform.
