This article presents the results of the calculation and design of a 50 m³ horizontal cylindrical gas tank designed for storing petroleum products. A key feature of the study is an 8% increase in internal excess pressure compared to the initial data, which allowed us to assess the impact of increased loads on the tank´s structural components: walls, bottoms, support and intermediate stiffening rings, and welded joints. During the study, the optimal geometric parameters of the tank were determined, the materials and thicknesses of the components were selected, and the strength, stability, and tightness conditions were verified. Particular attention was paid to the calculation of the flat-ribbed bottom and its connection to the wall. The results showed that with an increase in pressure to 5.94×10⁻³ kN/cm², the wall thickness can remain minimal (4 mm); however, to ensure strength in the connection area, a bottom with 24 radial ribs is required. All structural components meet regulatory requirements. The developed design can be used in the design of tanks for operation under moderately elevated pressure.

Keywords: horizontal gas tank, design, excess pressure, strength, stability, ribbed bottom, support rings.
