The two 24 gas export pipelines, E1 and W2, run from the Beregovaya
gas compression station in Russia s Arkhipo-Osipovka, 235 miles (378km) across the Black Sea, with a maximum water depth of approximately 2,150m, to the Durusu inlet terminal 40 miles (64km) from Samsun in Turkey.
and EDF International, and involving the construction of a 2,200-km gas pipeline from the Russian coast of Beregovaya
to the Bulgarian cost.
It will start at the Beregovaya
station on the Russian Black Sea coast, and from there will go to the Bulgarian Black Sea coast; from Bulgaria, the pipe is to split in two in order to reach Southern and Northern Italy.
Starting from Russia's Black Sea coast at Beregovaya
, South Stream would run some 900 kilometers on the seabed of the Black Sea, reaching a maximum water depth of more than 2,000 meters, to Bulgaria.
South Stream's first component is to send gas from the same starting point as the Blue Stream at Beregovaya
for under the Black Sea, at a maximum water depth of over 6,500 ft.
Bouygues Offshore's scope of work consist in providing the Beregovaya
gas compressor station on a turnkey basis.
The plans involve the modernization of the Russian Beregovaya
compressor station, run by Gazprom, and the Durusu Terminal in Turkey
Also in June 2007, Italy's Eni and Gazprom signed a memorandum of understanding on a feasibility study for the first component of South Stream that calls for sending natural gas from the same starting point as the Blue Stream pipeline at Beregovaya
for 560 miles under the Black Sea.
In its offshore section, South Stream will cross the Black Sea from the Russian coast of Beregovaya
- the starting point of the Blue Stream pipeline to Turkey - to the Bulgarian coast, with the pipe reaching a water depth of more than 2,000 metres.
CS in Russia and the Durusu receiving terminal in Turkey will be upgraded for this purpose.
It runs from Izobilnoya in Russia's Krasnodar state, to a new $300m compressor station built by Bouygues Offshore of France at Beregovaya
close to the Black Sea landfall at Dzhubga which is near Russia's Black Sea port of Tuapse.
