The invention provides an anti-ice type semi-submersible platform. The anti-ice type semi-submersible platform comprises a deck box, lower floating bodies and uprights, wherein the lower floating bodies and the uprights support the deck box, and the lower floating bodies are supported by the uprights. The anti-ice type semi-submersible platform further comprises anti-ice structures arranged on theuprights and extending outwards from the outer circumferential faces of the uprights, the longitudinal section of each anti-ice structure is triangular, one side of each triangle is a connecting side, each connecting side is attached to the outer circumferential face of the corresponding upright, and an anti-ice part is formed in the connecting position of the other two sides of each triangle. The upper edge of each connecting side is located above a work water plane of the anti-ice type semi-submersible platform. Each anti-ice part is located below a self-existing water plane of the anti-icetype semi-submersible platform and is not lower than the lower edge of the corresponding connecting side. By the adoption of the anti-ice type semi-submersible platform, floating ice or an ice layeris physically damaged through the anti-ice parts of the anti-ice structures, the ice face of the floating ice or the ice layer can be bent and broken through the rise of the anti-ice structures, so that the impact force of the floating ice or the ice layer is relieved, and the anti-ice type semi-submersible platform can be applied to polar region ice zone operation and has important value.
