Transneft Volga Region Completes Technical Upgrading of Electric Motors at Krotovka LODS in Samara Region

Date of publication: 14 December 2020

Transneft Volga Region has replaced the electric motors of mainline pump units (MPUs) at the Krotovka line operation dispatcher station (LODS) in Kinel-Cherkassy District of Samara Region.

The electric motors were replaced without interruption of pumping as part of the technical upgrading, revamping and overhaul programme of Transneft Volga Region’s operating facilities for 2020. The goal was to increase the equipment efficiency and to reduce energy consumption during its operation. These motors are parts of process equipment involved in the transportation of oil via the Buguruslan – Syzran and the Bavly – Kuybyshev oil trunk pipelines.

Three horizontal air-cooled asynchronous three-phase electric motors (with a power of 1,600 kW and a voltage of 6 kW each) were installed. The electric motors produced by the Russian Electric Motors plant (Chelyabinsk), a Transneft subsidiary, are distinguished by improved performance characteristics and increased service life of at least 50 years. Among design innovations is the application of special insulation, which uses a specialised glass tape with vacuum solvent-free epoxy resins mixture impregnation. This technology allows to additionally ensure high operational reliability of the equipment.

The new electric motors were connected to the LODS’s power supply system. The previously used equipment that had reached the end of its service life was dismantled.

The measures taken will allow to maintain uninterrupted oil transportation via the pipelines.
