Blue Stream

Blue Stream is a unique gas transportation project that is unparalleled in the world.

Eni holds a 50% interest in the Blue Stream underwater pipeline (with a record water depth of more than 2,150 meters) linking the Russian coast to the Turkish coast of the Black Sea. This pipeline is 774-kilometer long on two lines and has transport capacity of 16 bcm/y.

Owning one of the world’s largest pipeline-laying fleets and with extensive expertise in submerged gas pipeline construction, Eni was Gazprom’s key partner in the Blue Stream pipeline construction.Specific engineering solutions were applied during the pipeline construction in order to enhance reliability in an aggressive hydrogen sulphide environment. High-grade corrosion-resistant steel pipes with internal and external polymer coatings were used for construction and pipeline strength was tested at each stage. Mountainous and offshore sections of the pipeline were elaborated in detail and many other engineering solutions were applied.

On 16 November 1999, a special-purpose Russian-Italian joint venture, Blue Stream Pipeline Company B.V. was set up in the Netherlands by Gazprom and Eni on a 50-50 basis. The joint venture currently owns the offshore gas pipeline section, including the Beregovaya compressor station. Gazprom is the owner and the operator of the onshore gas pipeline section.

The construction of the Blue Stream onshore section started in September 2001 and was completed in May 2002; the total length of the section is 396 kilometres.

On 30 December 2002 the gas pipeline was commissioned. The first gas supplies via the pipeline took place in February 2003. The full capacity of the gas pipeline is 16 billion cubic meters per annum. As of June 2013, the total amount of gas transported via Blue Stream from the beginning of commercial supplies amounted to 90 billion cubic meters.
