The invention relates to a motion suppression device of a cylindrical ocean platform, and belongs to the technical field of ocean engineering. The motion suppression device comprises a rotatable suppression structure, a sliding suppression structure, a heaving suppressor array, a control unit and a platform motion monitoring system; the platform motion monitoring system in an ocean platform central control room controls the rotatable suppression structure and the sliding suppression structure through the control unit. The horizontal vortex-induced motion of the platform is effectively inhibited through the function that spiral plates in the rotatable suppression structure and the sliding suppression structure can disturb a flow field in ocean current, and the vertical projection area of aspiral strake is increased through the rotation of the rotatable suppression structure, so that the effect of inhibiting the heaving motion of the platform is achieved. The heaving, rolling and pitching motions of the platform are effectively inhibited through the synchronous and non-synchronous motions of the sliding suppression structure, so that the effect of efficiently inhibiting the motion of the platform is achieved, and the cylindrical ocean platform is more suitable for oil and gas production operation in a severe marine environment.

    本发明涉及一种圆筒形海洋平台的运动抑制装置,属于海洋工程技术领域;包括可旋转抑制结构、滑动抑制结构、垂荡抑制器阵列、控制单元和平台运动监测系统;海洋平台中控室中平台运动监测系统通过控制单元控制可旋转抑制结构和滑动抑制结构。通过可旋转抑制结构和滑动抑制结构中的螺旋形板在洋流中能够扰乱流场的功能来有效抑制平台的水平涡激运动,通过可旋转抑制结构的旋转增大螺旋列板的垂向投影面积,从而起到抑制平台垂荡运动的效果。通过滑动抑制结构的同步和非同步运动有效的抑制平台的垂荡和横摇、纵摇运动,从而达到高效抑制平台运动的作用,使圆筒形平台更适合在恶劣海洋环境下的油气生产作业。
