Diagnostics of the technical condition of metal structures of tanks and pipelines at «Akademik Vernadsky» UAS was carried out.At the preparatory stage, an analysis of design and operational documentation for tanks was performed, technical inspection methods were selected, equipment and auxiliary equipment were selected for performing diagnostic work using non-destructive testing methods. An instrumental inspection of the condition of metal structures of tanks and pipelines was carried out using nondestructive testing methods in order to identify defects and damage in structural elements and welded joints, an inspection of the condition of the foundation and base of the tank. Anti-corrosion work was carried out on the bottom of the tank and pipelines that had unacceptable corrosion damage were replaced. All elements of the tanks are in working technical condition and comply with current norms and standards for design, manufacture and operation. The static strength of the wall of the external and internal tanks corresponds to the project and current regulations. Due to anti-corrosion work on the bottom of the internal tank of RVS-200, its operation can be continued until 2029, provided that the rules for the technical operation of the tanks and the organization of annual monitoring of the technical condition of the tanks and technological equipment are followed. 20 Ref., 5 Fig.
