A central part of the Southern Gas Corridor, the Trans-Anatolian Natural Gas Pipeline (TANAP) connects the Shah Deniz gas field in Azerbaijan to Europe.

Vendor assessment services ensure quality for extension of South Caucasus Pipeline

Expected to cost US$7 billion, the initial 16 billion cubic meters of natural gas per year planned capacity of the pipeline will be steadily increased up to the maximum final capacity of 60 billion cubic meters. In order to efficiently, reliably and safely transport these quantities over such a distance, materials used in the construction of the pipeline must be of the utmost quality.

TÜV Rheinland Turkey was selected to provide vendor assessment services ensuring component operation and material durability. These services are necessary to carry out facility audits required for the pre-qualification of pipeline manufacturers. In addition, TANAP contracted TÜV Rheinland Turkey to conduct inspections at ten pipe mills and provide follow up services to ensure that both technical and systems skills had been brought up to current standards. TÜV Rheinland Turkey will support TANAP with a comprehensive range of services and extensive expertise throughout the scheduled four-year construction period.
