Disclosed is a tower body of a buoyant tower platform. The tower body at least comprises a housing (1) of a cylindrical structure; the bottom of the housing (1) is connected with a suction pile (2); and a diagonal plane (4) is arranged between the connecting position (3) of the bottom of the housing (1) and the suction pile (2) and the side edge of the housing. Therefore, the probability that the platform collides with a sea bed (5) during movement is greatly reduced.
