摘　　要：基于三维势流理论,在频域范围内,采用DNV船级社的SESAM软件系统,对某漂浮式潮流电站进行了水动力性能分析。通过分析,得出了横摇、纵摇、垂荡等响应变量的传递函数;结合载体实际工作时所处的海况,得出响应谱,并对其耐波性进行短期预报。计算结果表明,载体在横浪下垂荡和横摇较剧烈,各个浪向角下纵摇较接近。The hydrodynamic performance analysis of a floating current power station is presented with the DNV/SESAM in this paper. The analysis is carried out in frequency domain based on the three-dimensional potential flow theory. Transfer functions of motions, such as roll, pitch and heave are obtained. Besides, the short-term prediction of the seakeeping has been done and the response spectrum of the power station is obtained related to the actual sea state that the power station works on. The calculation result shows that the heave and roll is relatively violent in a beam sea, and the pitch is close in each wave direction.
