Moreover, 793 units of additional equipment used at oil and petroleum products trunk pipelines were inspected by Transneft Diascan in 2019. Diagnostics of 2,552 mechanical and process equipment units and 300 automation and pipeline telemetry systems were performed as well. 120,5 km of pipelines were inspected, full technical diagnostics was performed at 25,5 km of oil trunk pipeline (OTP) and PS lines.

The diagnostics were performed both using the Company’s own resources and with involvement of subcontracting organisations. As a result of the inspection, the condition of the examined facilities can be recognised satisfactory. The detected defects will be eliminated during scheduled repairs.
