In 2020, Transneft Siberia fully implemented the technical upgrading and revamping programme for the oil trunk pipelines’ (OTPs) and oil pumping stations’ (PSs) facilities.
During the year, construction of new facilities, revamping and overhauling of buildings and structures were performed at the PSs. In particular, 13 vertical steel tanks, 8 automated process control systems, and 13 pipeline telemetry systems were commissioned.
In order to automate the transported oil metering, the technical upgrading of 9 operational oil lease automatic custody transfer units and 3 oil meter skids was carried out.
To ensure reliable operation of operating facilities, specialists replaced 183 stop valves using electric drives manufactured by TOMZEL plant. During the year, 32 electric motors and 31 pump units were also replaced at the facilities. The new equipment produced by Transneft Oil Pumps is characterised by improved quality and energy efficiency indicators. Timely modernisation and upgrading allowed to improve industrial and environmental safety of operating facilities involved in oil transportation.
In December 2020, the comprehensive revamping of the Yuzhny Balyk line operation dispatcher station (LODS) of the Nefteyugansk Oil Trunk Pipeline Directorate (OTPD) was completed. In particular, modern microprocessor systems for processes’ automation and control were introduced, main and auxiliary equipment, process pipelines, engineering systems that had reached the end of their service lives were replaced.
To improve reliability of Transneft Siberia’s oil trunk pipelines’ system, 9 sections of the OTPs with a total length of 192 km were replaced and commissioned last year; 5.6 km of corrosive sections of the corridor were replaced as well. In addition, almost 2 thousand defects were eliminated at the OTPs.
To improve energy efficiency, in 2020, the technical upgrading of heating networks was carried out at the Uryevskaya LODS of the Nizhnevartovsk OTPD, and the Isetskoe LODS of the Tyumen OTPD. Heating networks were also repaired at 5 operating facilities, 2 boilers were replaced at the Kholmogory PS of the Noyabrsk OTPD.
The works provided for by Transneft Siberia’s technical upgrading and revamping programme ensure emergency-free operation and safety of the company’s operating facilities.
