Abstract

Background In the oil industry, a significant number of semi-buried reinforced concrete tanks in prefabricated and prefabricated monolithic designs are used to store hydrocarbon raw materials. Aims and Objectives An analysis of the results of a comprehensive survey of reservoirs in large tank farms for storing crude oil is presented. Results The article describes the constructive solutions of reinforced concrete tanks and the features of their operation. The results of assessing the technical condition of tanks located on the territory of the Republic of Tatarstan and the Bryansk region of the Russian Federation are presented. The technique and results of full-scale tests of tank cover plates are described, which have shown their usefulness in bearing capacity, stiffness, fracture toughness and serviceability in relation to design solutions after long-term operation under conditions of contact with low- and medium-sulfur oil. On the basis of the developed methodology for assessing the residual life of reinforced concrete structures of tanks, methods of repairing damaged structures are proposed in order to increase the durability of tanks for a period of at least 15 years.
