【摘要】：文章应用水动力学软件AQWA对在随机波浪荷载和风、流荷载联合作用下的浮动式发电平台的稳定性进行研究,分析了5种工况下该平台遭遇迎浪(0°浪向角)、艏斜浪(45°浪向角)、横浪(90°浪向角)时的横荡、纵荡、艏摇运动响应幅值,比较了该平台在破损工况(有系泊缆断裂工况)和完整工况(无系泊缆断裂工况)下的运动响应幅值。结果表明:平台的艏摇、横荡和纵荡运动响应的最大值分别发生在遭遇艏斜浪、迎浪和横浪时;在系泊缆断裂瞬间该平台所有方向运动响应均有大幅增加,其中破损自存工况下艏摇运动响应幅值是完整工况下的6~7倍。
[Abstract]:In this paper, the hydrodynamic software AQWA is used to study the stability of floating power platform under the combined action of random wave load, wind load and current load. The heave, longitudinal and yaw response amplitudes of the platform are analyzed when the platform encounters 0 掳wave angle, 45 掳wave angle and 90 掳wave angle under five working conditions. The motion response amplitudes of the platform under breakage (mooring cable breakage) and intact (no mooring cable breakage) are compared. The results show that the maximum response of yaw, heave and longitudinal motion of the platform occurs when the yawp wave, the swinging wave and the transverse wave are encountered, and the response in all directions of the platform increases significantly at the moment when the mooring cable breaks. The amplitude of the yawing response under the condition of self-stored damage is 7 times higher than that under the intact condition.
