The Blue Stream gas pipeline is designed to supply Russian gas directly to Turkey via the Black Sea. The Blue Stream supplements the gas transportation corridor from Russia to Turkey, which passes through Ukraine, Moldova, Romania and Bulgaria.
The pipeline has significantly increased the reliability of gas supplies to Turkey and promotes the development of gas market and gas infrastructure in the country. It is also able to cover peak demand growth in Turkey, associated with low temperatures regularly observed during the winter.
Specific engineering solutions were applied during the pipeline construction in order to enhance its reliability as the Russian mountainous section is over 60 kilometers long and the offshore section runs at depths of up to 2,150 meters in an aggressive hydrogen sulfide environment. For instance, these solutions include high-grade corrosion-resistant steel pipes with internal and external polymer coatings, pipeline stress testing, intellectual cut-ins at the mountainous and offshore sections, etc.
The total length of the Blue Stream pipeline is 1213 km, design capacity 16 billion cubic meters of gas a year.
The main partner in building the Blue Stream was the Italian company ENI, which has extensive experience building offshore pipelines.
In 2015 the pipeline transported 15.58 billion cubic meter of gas.
