In 2018, Transneft Western Siberia plans to conduct a range of works to inspect 28 tanks and 870 km in the linear portion of oil trunk pipelines.
Thus, in accordance with the approved schedule of tank farm inspection, Transneft Western Siberia will partially inspect 15 oil and petroleum products tanks from March till November 2018. The Company’s specialists will carry out a complete inspection of 13 tanks.
Modern inspection methods are used to perform a comprehensive assessment of the technical condition of the tank farm. Specialists review design and technical documentation, perform external examination of the tank’s structural elements, use geodesic measurements, acoustic emission diagnostics, visual and instrumental control and ultrasonic wall thickness tests. Also inspected will be the corrosion protection of metalwork and the foundation of the tanks.
Furthermore, in 2018, it is planned to perform in-line inspection of 13 sections of oil trunk pipelines, their length totaling 870 km. The linear portion of OTPs will be inspected using pipeline inspection gadgets (PIGs): a combined magnetic in-line defectoscope (DMC) and a combined ultrasonic in-line defectoscope (DCU-1). The technical performance and operation of modern PIGs allow performing in-line inspections without oil transportation shutdowns, as well as detecting, classifying and eliminating pipeline defects in good time.
Report documents are formed on the basis of monitoring results and contain exhaustive and trustworthy data on the technical condition of industrial infrastructure. Based on the data obtained, the Company develops a Programme of Technical Upgrading, Overhaul and Revamping for Transneft Western Siberia’s facilities.
