Transneft Siberia has summed up the results of diagnostics of oil pumping stations’ facilities.
In 2019, 46 vertical steel tanks (VST) were inspected, 18 of which passed complete technical inspection, and 28 – partial technical inspection. The tanks were examined using non-destructive testing methods involving ultrasonic, magnetic and acoustic emission inspection devices. According to the results of the diagnostics, 26 tanks’ safe operation period was extended, the rest are subject to overhaul.
In addition, complete and partial inspection of individual sections of process pipelines at nine Transneft Siberia oil pumping stations was carried out. At nine crossover lines between oil trunk pipelines, complete inspection was carried out with opening sections, removing old insulation, inspecting the pipe and restoring the insulation coating. In addition, a set of measures was taken to maintain horizontal location and elevation of the inspected pipelines.
In 2020, taking into account the postponed facilities, it is scheduled, in particular, to inspect 51 tanks, including 20 tanks which will pass complete inspection. The inspection of process pipelines and tanks is carried out in the time and extent provided for by Transneft’s Comprehensive Oil Trunk Pipeline and Pumping Station Facilities Diagnostics Programme in order to ensure emergency-free operation and environmental safety of Transneft Siberia’s oil trunk pipelines.
Timely evaluation of the technical condition and inspection of Transneft Siberia’s facilities will increase their environmental safety and reliability.
