Transneft Far East Completes Hydraulic Testing of Process Pipelines at ESPO-2 Oil Pipeline’s PS No. 27 under Revamping

Date of publication: 01 July 2019

Transneft Far East, in charge of oil transportation over the second phase of the Eastern Siberia-Pacific Ocean (ESPO-2) pipeline system, has finished hydraulic testing of the process pipelines at the tank farm under construction and the booster pump rooms at oil pumping station (PS) No. 27 near the village of Yekaterinoslavka in Oktyabrsky District of Amur Region.

The given sections built to service new facilities of the revamped PS will be included in the station’s general process network.

The pipelines of the tank farm and booster pump room at PS No. 27 were inspected from the tap-off point of the supply pipeline to the drainage pipeline of the booster pump station. The hydraulic testing was deemed successful.

The hydraulic testing of process pipelines at the ESPO-2 stations under construction has also been a success. Four sections have been tested at PS No. 23: from the pipeline clean-up and inspection gadget trap (PIG trap) to the stop valve unit at the PS exit. Four sections have been tested at PS No. 26: from mud-trap filters to the PIG trap.

The construction of PS No. 23 and 26 as well as the large-scale revamping of PS No. 27 are part of measures to increase the throughput capacity of the ESPO-2 to 50 million tonnes of crude per year. The new PS are booster stations without tank farms. Two 50,000-m3 oil storage tanks and two 5,000-m3 tanks are being built at PS No. 27 as part of the revamping.  Works on the project commenced in December 2017; their completion is scheduled for autumn 2019.

For reference:

Hydraulic testing is conducted to check the durability and strength of pipelines (takes 24 hours) as well as their containment (takes 12 hours).  Pipelines are filled with water under pressure that exceeds by 25% the designed working pressure of the station’s oil pipelines.
