The Trans-Anatolian Natural Gas Pipeline ( TANAP ; Azerbaijani : Trans-Anadolu Təbii Qaz Boru Kəməri , Turkish : Trans-Anadolu Doğalgaz Boru Hattı ) is a natural gas pipeline in Turkey . It is the central part of the Southern Gas Corridor , which connects the giant Shah Deniz gas field in Azerbaijan to Europe through the South Caucasus Pipeline and the Trans Adriatic Pipeline .
