Two new SVFRT-20000
tanks were put into service at the head pump station of CPC Pipeline System -
Tengiz PS. They were installed as part of the Debottlenecking Program (DBNP) in
2022-2023. The tanks with a capacity of 20,000 cu. m each are designated to
receive oil from Shippers; from these tanks the crude is then fed by booster
pumps to the trunk pipeline to be further transported via the pipeline system.
The new tanks
are equipped with floating roofs with a second seal; rising and falling with
the oil level, the roofs effectively prevent the formation of gas-air mixture
in the tanks and, as a consequence, its emission into the atmosphere. The old
tanks with pontoons have already been taken out of service: they are being
cleaned to be then removed. This work is to be performed in 2024.
As a
reminder: a new booster pump house with
four more powerful units, variable frequency drives site, pressure control
station were put into operation, crude oil quantity and quality measurement
system was upgraded and three mainline pump units were replaced at Tengiz PS in
the course of the DBNP.
The old
booster pump house is currently being dismantled at Tengiz PS. The work is also
in progress at the external power supply facilities: the power supplier’s
substation is being expanded and a new substation is being constructed at
Tengiz PS. These facilities are to be fully completed in February 2024.
To add: the
head Tengiz PS was built in 1989 and is involved in operation of the CPC crude
pipeline segment from KP0 to KP130. In the immediate vicinity of the station,
there is the TCO terminal and a valve station, from where oil is fed to the
Tengiz-Novorossiysk system by the overhead pipeline.
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.
