BAKU, Azerbaijan, July 10. The Caspian Pipeline
Consortium (CPC) resumed operations of its Tengiz-Novorossiysk oil
pipeline system on July 8, 2026, following a scheduled 12-hour
shutdown for maintenance works, the CPC press service reported.


During the shutdown period, CPC carried out routine maintenance
of various pipeline systems, oil pumping stations, and the Marine
Terminal, as well as repair works and activities related to current
and capital projects.


"In Kazakhstan, scheduled maintenance works were carried out at
pumping stations and along the linear section of the pipeline. Six
defects were repaired on the linear section. Pipeline bends were
replaced at the pig receiving and launching facility near the
Kurmangazy pumping station. A ball valve was replaced at the Tengiz
pumping station, while drain valves were replaced at the mainline
ball valve assembly near the Atyrau pumping station," the company
said.


In Russia's Astrakhan Region and the Republic of Kalmykia, CPC
inspected the tightness of four mainline ball valves, repaired
three defects using repair structures, and installed a vent valve
on the inlet manifold.


At pipeline facilities located in the Stavropol and Krasnodar
regions, the company carried out inspections of four ball valves
and replaced drain line valves at Pumping Station No. 8.


Maintenance works were also completed at CPC's Marine Terminal,
including activities on emergency diesel generators, pressure
regulation system valves at the tank farm and coastal facilities, a
multipurpose tank, and the receiving and launching chamber for
cleaning and diagnostic equipment.







CPC noted that 12-hour scheduled shutdowns, along with
maintenance periods of other durations, are planned in advance in
coordination with oil shippers. The schedule is also taken into
account by Kazakhstan's Ministry of Energy when preparing oil
transportation plans through the Tengiz-Novorossiysk pipeline.


The company said such planning ensures coordinated operations
among all participants involved in oil production and
transportation via the CPC pipeline system.


The CPC is a major international oil transportation project
involving Russia, Kazakhstan, and leading global energy companies.
The system includes a 1,500-kilometer pipeline transporting crude
oil primarily from Kazakhstan’s Tengiz, Karachaganak, and Kashagan
fields, as well as from Russian producers.


About 80% of Kazakhstan’s oil exports are transported through
the CPC system.
