Abstract: The article discusses approaches that increase the reliability and safety of operation of steel vertical cylindrical tanks. A constructive solution in the form of an additional protective wall is substantiated. This ensures environmental safety and minimizes the consequences of accidents associated with the violation of the integrity of the main wall of the tank and the outflow of all stored liquid within a short period of time. A spatial design model of a reservoir with a protective wall in the Lira PK is proposed. The parameters of the emergency hydrodynamic load acting on the protective wall of the tank are determined. The results of the study of the influence of hydrodynamic load on the stress-strain state of the protective wall are presented. Significant stresses and deformations exceeding the regulatory requirements were determined. Solutions to improve the design of the protective wall are proposed. The installation of an upper strapping and several tiers of stiffening rings, as well as an increase in the thickness of the supporting part of the bottom, ensure the strength and stability of the protective wall when exposed to a hydrodynamic shock load.

Keywords: steel vertical cylindrical tank, protective wall, stress-strain state, quasi-instantaneous failure, hydrodynamic shock, emergency.
