The development of the oil and gas industry of the Russian Federation requires reliable and trouble-free operation of the entire complex of facilities, but the facilities with the greatest potential damage in the event of emergency situations are of particular importance. These structures primarily include large-volume tanks located in the terminals for the shipment of oil. On the one hand, significant potential damage, on the other hand, a specific mode of operation with the presence of a significant number of drain-fill cycles throughout the life cycle makes these building structures a potential source of threat to all surrounding objects. In such a situation, the most important task is to prevent the occurrence of any defects in these structures. The development and expansion of the use of technologies of three-dimensional modeling of the real spatial position allows one to assess such potential threats that until recently remained poorly studied. Such threats primarily include the likelihood of fatigue cracks by the low-cycle load mechanism. The authors consider the current requirements (both Russian and foreign) for the accounting of these defects, shows their incompleteness and insufficiency. The article analyzes the possible locations of defects of this type, shows the potential for their implementation in local geometry defects that are not tied to welds. The authors set the tasks for further research of this problematic and tasks, the solution of which is necessary for the implementation of a full-fledged methodology for analyzing low-cycle strength of structures of vertical steel tanks.
