Buoyant tower platform

The invention belongs to the field of ocean platform engineering, and particularly relates to a buoyant tower platform. The buoyant tower platform comprises a suction pile, a fixed ballast tank, an adjustable buoyancy tank, a fixed buoyancy tank and an upper module which are sequentially and fixedly connected from bottom to top, wherein the suction pile adopts a tubular structure with a closed upper end and an open lower end; the adjustable buoyancy tank and the fixed buoyancy tank are both annular tanks and are concentrically arranged; and the internal space enclosed by the adjustable buoyancy tank and the fixed buoyancy tank is configured as an oil storage tank. The buoyant tower platform disclosed by the invention has the beneficial effects that the internal space enclosed by the adjustable buoyancy tank and the fixed buoyancy tank is configured as the oil storage tank, so that the internal space of a tower body is fully utilized for oil storage, the construction cost of an oil storage barge or an oil pipe
