Transneft Baltic has completed routine repairs of the pipelines and facilities of the Surgut – Polotsk, Yaroslavl – Moscow, Ukhta – Yaroslavl oil trunk pipelines (OTPs) and phase II of the Baltic Pipeline System (BPS-2).
The geography of repairs covered the Pskov, Yaroslavl and Leningrad regions.
Professionals from repair and maintenance divisions of Leningrad Regional Oil Pipeline Directorate (RPD) replaced two gate valves in the Lovat river underwater crossing of the Surgut – Polotsk OTP.
A newly-built 5-kilometre-long section of the Yaroslavl – Moscow OTP was connected at Yaroslavl RPD, and oil was displaced from the disconnected section. Three process gate valves in the pipelines of the tank farm, and four gate valves and a retention valve at the main pump station were replaced at facilities of Yaroslavl line operation dispatcher station. Altogether, 25 process gate valves were replaced with high-reliability sliding stop valves at Yaroslavl RPD.
By the planned date, specialists of Novgorod RPD mounted the last four line gate valves at the BPS-2 OTP. They completed the programme on installing into the pipeline of 35 sliding gate valves to implement no-pit oil pumping technology, which enhances industrial and environmental safety.
All the work was done under the integrated technical upgrading, revamping and overhaul programme of Transneft Baltic, targeted at maintaining high functional reliability of pipeline systems. The pipelines were brought back into operation as scheduled.
