The invention discloses a device and method for controlling vertical vibration of a semi-submersible platform through a rotating inertia damper. The device comprises a semi-submersible platform system, an anchoring system, a rotating inertia damper system and a water tank testing system. The rotary inertia damper system is used for controlling the vertical vibration of the semi-submersible platform system; the anchoring system prevents the semi-submersible platform system from shifting in the testing process; and the water tank test system is used for checking and testing the effectiveness of the rotation inertia damper system for controlling the vertical vibration of the semi-submersible platform system. The vertical linear motion of the semi-submersible platform system is ingeniously converted into high-speed rotation of the rotating pipe through the ball screw, so that the damping plate is driven to rotate, and a remarkable damping effect is provided for the semi-submersible platform system; the rule that the vertical vibration inherent frequency of the semi-submersible platform falls within the wave frequency range is determined, it is ensured that the semi-submersible platform and the fixed/tuned vertical vibration plate resonate in the vertical direction, and the control effect the same as or even better than that of a fixed/tuned vertical vibration plate is achieved through smaller physical mass.
