摘要
为了研究海底地形对浅水漂浮式风电系泊系统的影响,基于时域全耦合分析方法,利用OrcaFlex软件分别对在上坡式和下坡式海底地形条件下,采用悬链线系泊的半潜式漂浮风机纵荡运动以及系泊索受力进行了分析计算。通过与水平海底条件的计算结果对比发现:上坡海底地形会引起漂浮风机纵荡运动显著增大,系泊索张力随着斜坡角度的增大而减小;而下坡海底地形导致系泊索张力显著提高,但是对纵荡运动的影响恰好相反。因此海底地形对浅水漂浮式风机系泊系统的影响不可忽略。
In order to investigate the influence on mooring systems of FOWT by the bottom topography.Based on a time-domain coupled methodology,this paper employ OrcaFlex software to calculate the dynamic response of a moored semi-submersible FOWT.Compared with the results with respect to the flat bottom,the upslope bottom may exaggerate surge motion of FOWT and the mooring line tension decreases with the rising slope angle.On the contrary,the downslope bottom could lead to larger mooring line tension and smaller surge motion.Thus the effects by bottom topography on mooring systems in shallow water areas can not be neglected.
