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 south-eastern 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.

CaTRo comprises a marine channel, a Cargo Offloading Facility (COF) and a haul road to transport modules, connecting, among other places, the COF with Tengiz.
