The utility model discloses a strong-anti-outer-force high stability on-sea platform, which belongs to the technical improvement of an on-sea platform and can be used for oil extraction, gas extraction, mining and various civil and military on-sea movable buildings. The platform structure comprises a supporting structure and a platform which is arranged on the platform structure. The utility model is characterized in that the supporting structure is composed of tension legs, a lower truss frame, a floating tank and an upper pipe guiding frame, which are orderly arranged from the upper part to the lower part, wherein the tension legs are in a vertical type or an oblique pulling type; the floating tank is provided with a single tank or a plurality of tanks; the upper pipe guiding frame is in a fixing type or a self elevating type. The utility model has the advantages that the strong-anti-outer-force high stability on-sea platform in maximum reduces the level environmental load exerted on the platform, particularly the acting force of wind, wave, tide, flow and ice to improve the stability and security of the platform. The utility model has the advantage of low productive cost.
