CPC guarantees efficient and environmentally safe movement of crude oil

The Project is designed to increase the trunk pipeline capacity

Scope of scheduled shutdown

On April 14, 2023, at 07 am Moscow time, mainline pumps of the Tengiz-Novorossiysk trunk oil pipeline resumed pumping of crude oil after a 72-hour scheduled shutdown.

The above period was marked by scheduled work associated with planned maintenance of various systems of the pipeline and the Marine Terminal (mechanical and process equipment, power and electrical equipment, instrumentation and automation systems, control systems), as well as work on the ongoing and capital projects of CPC. Performance of the above work is only possible during shutdown of pump station and pipeline equipment. 

As part of current operations, CPC and contractor personnel checked operation of emergency shutdown and unit protection systems for the entire length of the pipeline. Scheduled replacement of ball valves was performed at PS Atyrau in the Republic of Kazakhstan and at PS-4 pig launcher/receivers in the Russian Federation. A significant work scope was also performed on the pipeline. Heat shrink sleeves were replaced on a number of pipeline sections; defects were fixed by installation of P2 and P5U repair sleeves. As part of a relevant program, eight obsolete electric drives of mainline ball valves were replaced.

To implement capital projects of the CPC base business in the Russian Federation, during scheduled shutdown, a large scope of work was performed under fire and gas detection systems upgrade at PS Komsomolsk and PS Kropotkin. Work related to power supply reliability improvement was successfully implemented at the CPC PSs located in the Stavropol Krai, Krasnodar Krai and the Marine Terminal.         

As part of Debottlenecking Program, three LACT meter units recently installed under DBNP were filled with oil; and a new control room building was commissioned, which allows proceeding with metrological certification of the new LACT units. Disconnection of the existing mainline pump house from the pipeline was performed at PS Astrakhan. Work was performed in strict compliance with DBNP schedule.

In the Republic of Kazakhstan, during the shutdown, a number of activities were delivered on the upgrade of fire and gas detection system at PS Tengiz. Work was also performed on the upgrade of PS Atyrau power supply system. Critical activities associated with construction of two new 20,000 m3 tanks were successfully completed on schedule. Commissioning of the tanks is scheduled for 2023.   

Scheduled shutdowns are performed a few times per year to ensure delivery of the types of maintenance, repairs and equipment connection that cannot be performed on operating equipment.  CPC does not practice advance notifications to the public and expert community about pipeline shutdown. This practice is due to security matters and combating illegal taps.

Currently, lifting of crude oil at the Marine Terminal is delivered routinely.

For information:

CPC Pipeline System is one of the major investment projects with foreign capital in energy sector in the CIS. The length of the Tengiz – Novorossiysk pipeline is 1,511 km. This route transports over two-thirds of all Kazakhstan export crude, as well as crude from Russian oil fields, including those in the Caspian Region. CPC Marine Terminal is equipped with three Single Point Moorings (SPM) that allow to load tankers safely at a significant distance offshore, also amid poor weather conditions.
