In this paper, the influence mechanism of compressed air in the semi-enclosed buoy on the air-floating state and the floating stability of the structure is introduced, and the calculation and analysis method of the static-stable floating state of the air-floating structure is established. Assuming that the air in the buoy is an ideal gas, the relationship between the calculation formula of the gas buoyancy and the force balance of the flotation structure is derived. Based on this, the calculation methods of various characteristic parameters of air-float structure are given. The theoretical calculation results are in good agreement with the model test and field test data, which shows that these calculation theories can be applied in engineering. Reasonable use of flotation characteristics can be a number of large bottomless cylinder-type structures for offshore airlift haulage and installation
