Applying Technology

Date of publication: 28 May 2021

Modern technology ensures uninterrupted and safe operation of pipeline transport in the Arctic.

Developing the industrial potential and utilising most advanced technologies is the approach used by Transneft East for industrial and environmental safety.

Among the top priorities of Transneft East is the conservation of unique nature of Siberia and the Russian Far East

The largest pipeline system Eastern Siberia – Pacific Ocean (ESPO PS) is a strategically significant national facility. Energy transportation via the oil pipeline must be done safely and according to the schedule. A reliable, accident-free and environmentally friendly operation of the steel line is ensured by people and technologies, of course.

A large part of the oil pipeline runs over remote underpopulated territories with low temperatures in permafrost. Transneft East focuses on integrating technology and implementing the latest developments in the construction and operation of facilities located in the Arctic.

One of such effective developments, heat stabilizers, was put into operation at the ESPO-1 oil pipeline. These devices are needed to enhance the load carrying capacity of terrain by its cooling and freezing. Heat stabilizers are sunk to the depth of up to 25 metres and filled with an antifreeze that helps maintaining negative temperatures in the permafrost where the pipe is laid.

Every year during the cold season Transneft East’s employees, together with their peers from Transneft R&D, monitor heat stabilizers on a regular basis – as a matter of fact, more than 20,000 such devices were inspected during the month of April. Such devices are used not only in Yakutia and Amur Region, but also in the north of Krasnoyarsk Territory, Evenkiya, at the Kuyumba – Tayshet oil pipeline.

Furthermore, the cutting-edge inspection devices are on the lookout for the safety of Transneft East’s oil pipelines. Unique inspection tools developed by Transneft which combine several inspection methods allow simultaneous high-precision detection of several types of pipe defects. 40 sections were inspected in 2020 at the pipelines ESPO-1, Krasnoyarsk – Irkutsk and Kuyumba – Tayshet.

Transneft East put the Oil Pipeline Unified Supervisory Control System (USCS) into commercial operation to optimise running and monitoring of its oil pipelines. The system allows the control of process equipment at the pipelines Omsk – Irkutsk and Krasnoyarsk – Irkutsk from a single regional control centre.

Updates on the condition of the process equipment at all oil trunk pipelines of the Company – pressure in the pipeline system, velocity, throughput volume of transported crude, and other important transportation parameters – are transmitted online to the central control room of Transneft from regional control rooms. In case of any deviations, the unified control system may even adjust the equipment performance parameters at the oil pipelines.

An external surveillance audit confirms the proper choice of operational priorities. Every year specialists from the reputable international certification and expert institution DQS check the Company’s environmental management, energy management, occupational health and safety management systems for their compliance with the international standards. Following their inspection, the experts made note of the Company’s positive experience in all areas of production activities. All three Transneft East’s internal corporate management systems were recognised as complying with the international requirements in the field of operation of pipeline transportation facilities.

For reference

Transneft East ensures uninterrupted operation of phase I of the oil pipeline system Eastern Siberia – Pacific Ocean from Tayshet to Skovorodino, as well as of the Skovorodino – Mohe section at the Russian-Chinese oil pipeline. Furthermore, the Company operates the Kuyumba – Tayshet oil pipeline along with Omsk – Irkutsk and Krasnoyarsk – Irkutsk pipelines running across the territory of Irkutsk Region. Overall, more than 4,500 km of pipelines are operating under the control of Transneft East.
