- Destination: Varna on Bulgaria's Black Sea coast
- Ownership: Gazprom / ENI / Wintershall / EDF
- Website: http://www.southstream.ch/
- Length: kilometres ( miles)
- Capacity: 63 billion cubic metres per annum
- Status: Planned (Construction to start 2012)
- The 900 kilometres (560 mi) long offshore section of South Stream would start from the Beregovaya compressor station at the Russia’s Black Sea coast, and would run to Bulgaria's Varna.
- The pipeline route will cross the continental shelf of Ukraine and Romania. According to the UN Convention on the Law of the Sea, the delineation of the course for the laying of such pipelines on the continental shelf is subject to the consent of the coastal State.
- This section would be built and operated by South Stream AG, a joint company of Gazprom and Eni.
- From Varna, the south-western route would continue through Greece and the Ionian Sea to southern Italy.
- Greece has proposed that the southern pipe may also supply the Turkey-Greece-Italy pipeline.
- The north-western pipeline will run through Serbia, Hungary to Austria ending at the Baumgarten gas storage. Another option is that the north-western route would run through Slovenia to northern Italy. It is possible that two smaller parts will go through Bosnia and Herzegovina to the Port of Plo?e and another through Croatia to Port of Rijeka and pipeline end in Italy's Port of Trieste. There are also talks that the South Stream pipeline will be connected to the Wingas-owned Haidach gas storage, the second largest gas storage in Central Europe.
