The Baku–Supsa Pipeline (also known as the Western Route Export Pipeline and Western Early Oil Pipeline) is an 833-kilometre (518 mi) long oil pipeline, which runs from the Sangachal Terminal near Baku to the Supsa terminal in Georgia. It transports oil from the Azeri-Chirag-Guneshli field. The pipeline is operated by BP.
The preparations for the pipeline's construction started in 1994. On 8 March 1996, President of Azerbaijan Heydar Aliyev and President of Georgia Eduard Shevardnadze agreed on the establishment of Baku–Supsa pipeline. The trilateral contract was signed between Azerbaijan International Operating Company, SOCAR and the Government of Georgia. At the same year the lead contract of the project was awarded to Kværner. The pipeline was completed in 1998. On 17 April 1999, the inauguration ceremony of the Supsa Oil Terminal took place. The total costs of the construction of the pipeline and terminal were US$556 million.
The oil transportation by the pipeline was stopped on 21 October 2006 after abnormalities were revealed during the inspections on the pipeline. The large scale repair and replacement included replacement and re-routing of pipeline sections near Zestaponi in Georgia and Kura River crossing in Azerbaijan. Also several defects of the Soviet times sections were repaired. In total, the repair works cost US$53 million. The oil shipment restarted in June 2008.
After a major explosion and fire, which closed the Baku–Tbilisi–Ceyhan pipeline on 6 August 2008, the Baku–Supsa Pipeline was used to re-route Azeri oil deliveries. On 12 August 2008, BP closed the pipeline temporarily for the safety reasons because of the South Ossetia conflict. In Summer of 2012 pipeline was down a month for a maintenance.
In July 2015 Russian troops demarcating the de facto border of the self-proclaimed Republic of South Ossetia, pushed forward the border line near the village of Orchosani and thereby taking control over a short length of the pipeline.  Analysts suggest that this was a Russian reaction to dissuade Georgia from making further moves towards joining NATO.  While conceding that the pipeline might need to be diverted in the future, a Vice President of SOCAR reportedly denied any short term need for such concern.
Essentially, the Baku–Supsa pipeline is a refurbished Soviet era pipeline with several newly built sections. It has six pumping stations and two pressure reduction stations in western Georgia. The four storage tanks at the Supsa terminal have a total capacity of 160,000 cubic metres. The capacity of the pipeline is 145,000 barrels per day (23,100 m3/d) with proposed upgrades to between 300,000 to 600,000 barrels per day (48,000 to 95,000 m3/d).
