The invention discloses a semi-submerged platform main body structure capable of improving vortex-induced motion performance. The semi-submerged platform main body comprises a lower floating body and four stand columns connected with the lower floating body; and the stand columns have special cross section shapes and special arrangement modes. The structure can be used for effectively inhibiting the vortex-induced motion of the platform, improving the related hydrodynamic performance of the platform, reducing the fatigue damage of vortex-induced motion on mooring and riser systems, and reducing extra consumption of vortex-induced motion on the power of a dynamic positioning propeller.
