From the beginning of 2015 Transneft Diascan, JSC diagnosed 370 tanks for oil and oil products storage. The works were conducted both by using own resources of the enterprise and with the assistance of subcontracting organizations within the limits of Overall Program of Diagnostic Examination of Pipelines and Objects of PS of Transneft, JSC for 2015.
At 79 tanks partial technical diagnostics was conducted without removal of the constructions from service, at 44 objects full technical diagnostics was conducted, the tanks were not in service at the time; at other 247 ones works for additional diagnostics (acoustic emission diagnostics of bottom, control for condition of external anticorrosive coating, additional inspection of foundation, radiographic inspection of welding joint of flange pipe junction welding to water discharge pipe junction in the tanks etc.) were conducted. In the process of examination methods of ultrasonic, acoustic and emission examination and radiographic control were applied. According to the results of the diagnostics condition of the examined objects was declared satisfactory.
The main part of works was conducted at the objects of Transneft Urals, JSC (57 tanks), Transneft Siberia, JSC (54 tanks), Transneft Western Siberia, JSC (42 tanks), Transneft Volga Region, JSC (40 tanks), as well as Transnefteproduct Samara, JSC (30 tanks).
