The Cargo Transportation Route (CaTRo) is a part of Tengizchevroil (TCO) FGP-WPMP Project. Its objective is to transport large cargo to oil fields located in the southeastern part of Atyrau Oblast. This route is designed to transship cargo carried by river/sea transport to the Caspian Sea’s northeastern shore near the Prorva field and deliver them further by land transport to oil fields.

AVENCOM Responsibility

AVENCOM won a competition and took an EPC contract for fiber optic network infrastructure at CaTRo. The company played a vital role at all stages from the functional design and engineering, through procurement, installation, configuration, to site acceptance tests and trainings.

AVENCOM Approach

As part of the design, AVENCOM engineers developed more than 250 drawings, tabular, and text documents. During the preparation of the cable infrastructure, our specialists terminated and tested about 3000 optical fibers, as well as about 1200 UTP cables.


The data transmission network consists of more than 80 active nodes. All access switches provide service at a speed of 1 Gbps with PoE power on each port. The trunk connections are built on the base of Ethernet rings operating at a speed of 10 Gbps. The multi-tenant architecture allows provision of services for users from different departments within the same network. In this way, cost savings in equipment and maintenance personnel are achieved while preserving the mutual independence of customer networks.

The deployed network infrastructure started the high-level service rendering at early construction stage proving its efficiency as data transport platform for other IP based network domains in CaTRo project.
