Transneft Far East Connects Oil Pumping Stations under Construction to External Power Supply Lines

Date of publication: 31 May 2019 Print

Transneft Far East which operates the Eastern Siberia – Pacific Ocean pipeline system, has taken measures to connect oil pumping stations under construction (PS) to external power supply (EPS) lines: PS No. 23 in Magdagachinsky District and PS No. 26 in Seryshevsky District (Amur Region), PS No. 32 in Smidovichsky District (Jewish Autonomous Region).

At each PS, PMC ESPO and Transneft Far East built step-down substations (SS) and installed two power transformers with a capacity of 25 MW each. It was necessary to construct six line approaches: two from each substation, to connect the step-down substations to the existing electric power transmission lines.

In addition to providing electrical energy to the oil pumping station, the step-down substations of Transneft Far East are to transit electrical energy in case of an emergency shutdown of one of the two operating EPS lines. For this purpose, 4 high-voltage switches are assembled at each of the step-down substations.

The equipment is now being tested under the conditions of continuous operation. The commissioning of the Transneft Far East EPS is scheduled for the third quarter of 2019.

For reference:

The construction of PS No. 23, 26 and 32 is carried out under the Expansion of Phase II of the Eastern Siberia – Pacific Ocean Pipeline System (ESPO-2) up to 50 Million Tonnes project. The new PSs are booster stations without a tank farm for oil storage. They will ensure the necessary pressure inside the oil pipeline to pump additional volumes of oil.  The installation of the new stations began in December 2017, the construction is to be completed in the fall of 2019. The construction is carried out by PMC ESPO (a subsidiary of Transneft), the stations will be operated by Transneft Far East, which ensures oil pumping via the ESPO-2.
