The widespread use of vertical cylindrical tanks puts the question of their sustainable design. Snow load brings the greatest contribution to the stress-strain state of the supporting structures of vertical tanks spherical domed coatings in the IV-VIII snowy areas of Russia.New geometrical forms of the tank coatings with volume 20 000 m3 were developed. The results of aerodynamic research of proposed coatings model were presented.The coefficients of the external pressure on the surface of the walls and coating of the tank were determined. Qualitative and quantitative picture of the snowy mass under the influence of the wind were also determined.The obtained results can be used to develop effective design solutions for domed coatings of the oil tanks.
