Karachaganak Atyrau Transportation System (KATS) is the main export route for stabilised liquid hydrocarbons produced at the Karachaganak Field and these pipelines have been in operation since 2003. The transportation system consists of a 24 inch buried pipeline from the Karachaganak Processing Complex (KPC) to Atyrau on the Caspian Sea. There are two pumping stations; one at Bolshoi Chagan and one at KPC and a receiving and storage facility in Atyrau. KPO operates and maintains all of these facilities. In Atyrau, the line connects to the Caspian Pipeline Consortium (CPC) system which transports oil to Novorossiysk where it is loaded on tankers and exported.
