摘要
为了分析风电安装船在实际海况下的运动响应及阻力性能,基于三维势流理论,本文对风电安装船进行频域和时域运动响应数值分析,并开展风电安装船模型试验,对航行阻力、幅频响应函数和在位运动响应进行试验研究。通过试验得到风电安装船在航速13 kn时阻力为899 k N,RAO响应曲线和不规则波中的运动幅值验证了数值计算的准确性。研究结果表明风电安装船在十年一遇的北大西洋海况中运动幅值较大,不宜进行安装作业。
In order to study the motion response and resistance performance for the wind turbine installation vessel （WTIV）, based on the three-dimensional potential flow theo~ the numerical analysis of the vessel＇s motion response is conducted in frequency and time domain. The model test of the WTIV is also carried out, including resistance test, RAO test and irregular test. Through the test, the resistance of the WTIV at the speed of 13 kn is 899 kn. The RAO response curve and the motion value of the irregular test verify the accuracy of the numerical calculation. The results show that the WTIV has large motion value in the serious sea condition often years on the North Atlantic Ocean, which is not suitable for installation.
