Baku-Supsa Pipeline

One of the pipelines transporting Azerbaijani oil to the world market is the Western Export Pipeline or Baku-Supsa pipeline, which starts in Sangachal Terminal and ends in Georgian Supsa Terminal. This has been an integral part of Azerbaijan’s oil export system created after the signing of the Contract of the Century.

First oil was shipped in Supsa on the 8th of April 1999. The official opening of the pipeline took place on the 17th of April. The presidents of Azerbaijan, Georgia and Ukraine, and the US president’s adviser on the Caspian region attended the ceremony.
