Transneft Siberia has completed technical upgrading and commissioned electrochemical protection (ECP) system of process and auxiliary pipelines at the Tyumen petroleum products pumping station (PPPS) of the Tyumen Oil Trunk Pipeline Directorate.

Work on technical upgrading of the ECP system of process and auxiliary pipelines operating since 1997 was performed since April this year. The purpose is to protect underground structures against corrosion caused by the exchange of electrons from the body of pipelines as a result of electrochemical processes in the soil.

During the upgrading of the ECP system, specialists replaced ten cathodic protection transformer stations with impulse stations of 5 kW for the Shaim – Tyumen and Tyumen – Yurgamysh pipelines and 3 kW for process pipelines reservoir, respectively. The anode deep well beds (installed in 50 m deep wells) were also replaced with extended anodes located along the oil pipeline and the petroleum products pipeline. The 38 iron gauge racks of test station units with a circle section were replaced by plastic equivalent with a square section with easy access for maintenance and necessary measurements. Cathodic protection for the enclosures of the oil trunk pipeline and petroleum products pipeline was mounted at the crossing under the railway at the outlet from the Tyumen PPPS.

All equipment is manufactured in Russia and meets the requirements of technical rules and regulations of Transneft. Modern cathodic protection stations are implemented on the basis of pulse transducer with absence of pulsations and maximum output current stability. New reference electrodes with extended service life, designed to control protective potentials, were installed on the Tyumen PPPS tanks.

After comprehensive testing, the ECP system of process and auxiliary pipelines of the Tyumen PPPS was commissioned and is operating under the standard protocol.
