摘　　要：运用MIKE 21 Mooring Analysis系泊分析软件,针对15万t系泊油船,研究在横浪、顺浪作用下,缆绳属性变化对于系泊油船运动量以及缆绳受力的影响。研究结果表明,在横浪的工况下,系泊油船的横移、纵移、回转三个运动量随着缆绳刚度的增大而减小;在顺浪的工况下,在入射波浪周期较小的情况下,随缆绳刚度的增大,系泊油船的纵移运动量减小、纵摇略有增大。在入射波浪周期较大的情况下,随缆绳刚度的增大,系泊油船的纵移运动量增大、纵摇减小。横摇、回转、横移三个运动量大体上随缆绳刚度的增大而增大,但是变化幅度较小。两种工况下升沉量基本不随缆绳刚度变化。The Mooring Analysis software MIKE 21 was used to study the influence of the change in cable material on the motion and the strain on the cable of the moored oil tanker up to 150000 DWT under the action of transverse wave and following wave.The results show that the three motions of moored oil tanker such as sway,surge and yaw decrease with the increase of cable stiffness under the condition of transverse wave.With the increase of cable stiffness,the surge of the moored oil tanker decreases and the pitch increases slightly under the condition of following wave and short incident wave period.However,the surge of the moored oil tanker increases and the pitch decreases with the increase of the cable stiffness under the condition of long incident wave period.The motions of roll,yaw and sway increases with the increase of cable stiffness,which changes within a small range.In addition,Heave does not change with cable stiffness under the above two conditions.
