Transneft Urals has completed technical upgrading of telemetry systems at sections of the Ust-Balyk – Kurgan – Ufa – Almetievsk, the Nizhnevartovsk – Kurgan – Kuibyshev and the Tuimazy – Omsk – Novosibirsk-2 oil trunk pipelines in the territories the Kurgan and Chelyabinsk oil pipeline directorates (OPDs) are responsible for.
The Company replaced pipeline telemetry cabinets, lower-tier telemetry system equipment (pressure transducers, pressure gauges, flood alarms in manholes for instruments and meters), cable products and fire alarm systems equipment. Moreover, pressure taps and pressure gauge racks were replaced inside manholes for instruments and meters at facilities under technical upgrading in the Chelyabinsk OPD.
The new equipment has a number of advantages over the equipment used previously. Controllers use data transmission protocols accepted at Transneft and support communication channels redundancy. The power supply diagram ensures standalone operation of telemetry cabinets for at least 3 hours in case of power outage, and electronic components are protected from overvoltage. The fire alarm permits no false fire messages, the software of telemetry cabinets enables to rule out spontaneous changes in the position of stop valves in the line. The controllers offer enhanced capabilities of self-testing and troubleshooting, which helps detect the causes of troubles more precisely.
The new telemetry cabinets were manufactured by the Industrial Automation Centre of Transneft Upper Volga; the software for pipeline telemetry controllers was developed by professionals of the SW&HW Support Section for Microprocessor Automation and Telemetry Systems at Transneft Urals.
The upgrading was done primarily using domestically manufactured equipment – fire alarms, pressure gauges, manhole flood alarms, PIG travel sensors.
The work was performed as part of Transneft Urals’ technical upgrading and revamping programme.
