From January to July 2018, the Inspection Directorate of Transneft Diascan inspected 333 oil and petroleum products storage tanks. The inspection efforts were carried out under the integrated programme for diagnostic inspection of pipelines and facilities of Transneft PSs for 2018.

Overall, 56 tanks underwent complete technical inspection with decommissioning, and 58 tanks saw partial technical inspection without removal from operation.

The efforts included 219 additional tank surveys: tank monitoring (37 pieces), technical condition monitoring of aluminium dome-shaped roofs at vertical steel tanks (8 pieces), condition monitoring of external and internal anticorrosive coating (96 pieces), an additional defect detection (X-ray) of welds between the 3rd and the 4th belts of the tank wall (55 pieces), and other work. The survey employed ultrasonic, acoustic emission and industrial radiography inspection methods.

Most of the work was performed at facilities of Transneft Druzhba (58 tanks), Transneft Western Siberia (39 tanks), Transneft Kama Region (38 tanks), Transneft Siberia (35 tanks) and Transneft Urals (29 tanks).
