The article features the application of a method of displacement during major repairs of vertical steel tank bases. Premises on the effectiveness of the application of the displacement method for repairing the bases of vertical steel tanks in comparison with the traditional method of repair are put forward. The comparative characteristics of the displacement method and the traditional method of major repairs of the bases of vertical steel tanks are given. The authors proposed a method of temporary displacement of vertical steel tanks, which is new for Russian practice of major repairs. An algorithm for calculating the cost-effectiveness of repairing the bases of VSTs is developed both by the traditional method and by the displacement method proposed by the authors. Technical solutions are substantiated considering calculating the stress-strain state of tank structures under nonaxisymmetric loading. A model is formed and basic parameters of the economic efficiency evaluation of major repairs of the vertical steel tank base are determined. Evaluation of the economic efficiency of major repair procedures and further maintenance of the repaired tank bases is carried out. A high economic efficiency of the new technological method of displacement is proved in comparison with the traditional method.
