The invention relates to a tension leg platform for improving vortex-induced motion performance, the tension leg platform comprises an upper module, a plurality of cylindrical columns arranged below the upper module and perpendicular to the upper module, and the platform further comprises expansion columns in a cylindrical shape, the diameter of the section of the expansion columns is at least 10% larger than the diameter of the columns, The expansion columns are equal to the columns in number and correspond to the columns in a one-to-one mode, the expansion columns are connected to the bottoms of the corresponding columns, the axes of the expansion columns are aligned, and floating boxes are arranged between the adjacent expansion columns. Compared with the prior art, the expansion columns are arranged, the diameter of the section of the expansion columns is at least 10% larger than the diameter of the columns, vortex-induced motion formed by the columns and the expansion columns forms an obvious phase difference, the period is kept unchanged, and therefore the vortex-induced motion of the two parts can be partially counteracted, and the vortex-induced motion performance is obviously improved; vortex-induced motion amplitude is reduced, and fatigue damage, caused by vortex-induced motion, of the column and the stand pipe system is reduced.

    本发明涉及一种改进涡激运动性能的张力腿平台,包括上部模块、多个立柱,立柱呈圆柱状,设于上部模块的下方,且均与上部模块垂直,平台还包括扩大柱,扩大柱的形状呈圆柱状,截面直径大于立柱直径至少10%,扩大柱的数量与立柱的数量相等并一一对应,各扩大柱连接于对应立柱的底部且轴线对齐,相邻扩大柱之间均设有浮箱。与现有技术相比,本发明通过设置扩大柱,由于扩大柱截面直径大于立柱直径至少10%,立柱和扩大柱两部分形成的涡激运动形成了明显的相位差,并且保持周期不变,从而两部分的涡激运动可以部分抵消,从而明显提高涡激运动性能,减小涡激运动幅值,降低涡激运动引发的立柱和立管系统的疲劳损伤。
