According to Gazprom the pipeline was built with the intent of diversifying Russian gas delivery routes to Turkey and avoiding third countries.

[2] One of the political goals of the Blue Stream project was to block the path of rival countries aiming to use the territory of Turkey to bring gas from the Caspian area to Europe.

[7] However, because of the price dispute between Russia and Turkey, the official inauguration ceremony at the Durusu gas metering station took place only on 17 November 2005.

Blue Stream full capacity is 16 billion cubic meters (bcm) of natural gas per year.

[10] Gas from Blue Stream started to flow in February 2003, and the pipeline delivered 1.3 bcm to BOTAŞ in 2003.

In 2005, Vladimir Putin and Recep Tayyip Erdoğan discussed building a second line, and an expansion of the Blue Stream by the Samsun-Ceyhan link and by branch to southeast Europe.

In 2009, Russian prime minister Putin proposed a line parallel to Blue Stream 1 under the Black Sea, and further from Samsun to Ceyhan.
