Transneft Western Siberia has summarised the results of inline inspection programme for trunk pipelines in the Company’s responsibility area for 7 months of 2018.

From January to July, 9 sections of oil trunk pipelines (OTPs): the Omsk – Irkutsk, Anzhero-Sudzhensk – Krasnoyarsk, Krasnoyarsk – Irkutsk and Ust-Balyk – Omsk OTPs with the total length of 413 km were inspected under the approved schedule, including approximately 10 km of OTPs’ underwater crossings at the Ishim, Yenisei, Kan and Kiya Rivers. By the end of the year, professionals will inspect 5 more trunk pipeline sections with the length of as many as 472 km.

The technical condition monitoring is conducted to timely detect deviations from standard OTPs operational parametres. The inline inspection data is used by Transneft Western Siberia to develop Production Facilities Technical Upgrading, Revamping and Overhaul Programmes. It also elaborates a plan for elimination of identified defects at OTP sections by selected repairs. The remedying work is done both during scheduled shutdowns and during oil and petroleum products transportation.

Transneft Western Siberia monitors technical condition of OTPs using domestically manufactured state-of-the-art pipeline inspection gadgets (PIGs) for various inspection methods (magnetic and ultrasonic). A next-generation ultrasonic inspection suite will be used for inspecting OTPs next year. This PIG is designed for multiview inspection of trunk pipelines’ walls; its technical features enable to get additional info about longitudinal and lateral defects as well as weld defects.

From January to July 2018, the Company performed technical inspection of Transneft Western Siberia’s vertical steel tanks. Professionals have fully inspected 7 tanks with the total capacity of 95,000 m3 and partially inspected 13 tanks with the capacity of 110,000 m3.
