Transneft Kama Region has completed scheduled repairs of oil trunk pipelines (OTP) in Samara Region, Perm Territory and the Republic of Tatarstan.
In the course of a planned 65-hour decrease in the volume of transportation through the Surgut – Polotsk oil trunk pipeline, two gate valves were cut out as part of bringing the PIG trap to standard parameters. At the Perm LODS, a tank of 20,000 m3 was disconnected for cleaning and diagnostics works.
During a scheduled shutdown of the Almetievsk – Aznakayevo-2 and Chekmagush – Aznakayevo trunk oil pipelines for 55 hours, a crossover line was connected between the Ust-Balyk – Kurgan – Ufa – Almetievsk OTP and the Aznakaevo PS. A pressure manifold was connected to the Aznakayevo PS as part of construction of a PIG trap of the Kaltasy – Kuybyshev OTP. At the Almetievsk – Kuybyshev-1 TP, a section with the length of 14.5 km was connected as part of the revamping works.
At the Kaleikino PS, two gate valves were replaced and a tank with the volume of 20,000 m3 was connected to the technological pipelines after revamping. The events at the Almetievsk – Kuybyshev-2 OTP were held without reducing the regime and took 72 hours to finish.
As part of the revamping works, 25 repair pits were dug out and more than 320 pieces of equipment were involved. The works were carried out 24/7 by repair teams of the Perm, Udmurtia, Kazan, Almetievsk and Romashkino Regional Oil Pipeline Directorates of Transneft Kama Region. In particular, technical assistance was provided by Transneft North, Transneft Volga Region and Transneft Upper Volga.
The scheduled works were completed as part of Transneft Kama Region’s comprehensive technical upgrading, revamping and overhaul programme. The goal was to maintain operational reliability of the trunk pipelines.
Oil transportation was resumed on schedule, and now oil pipelines are operating under the standard protocol.
