Southern Corridor gas pipeline system

Significance

South Stream
 Enabling to supply additional volumes of natural gas to Russia’s central and southern regions, the Southern Corridor gas pipeline system will develop industries and utilities, intensify gasification and ensure uninterrupted gas supplies into the South Stream gas trunkline.

Major features

What are the features of offshore production

Total length of the gas transmission system will account for 2,506.2 kilometers. The project requires that 10 compressor stations  are constructed with total capacity of 1,516 MW. The annual throughput of the Southern Corridor gas pipeline system will amount 63 billion cubic meters. The project period is from 2010 to 2017.
The project is executed within 8 Russian Federation constituents: the Nizhny Novgorod, Penza, Saratov, Volgograd, Voronezh, Rostov Regions, the Republic of Mordovia and the Krasnodar Territory.

Construction phases

The project is divided in two phases.

Southern Corridor gas pipeline system construction phases

Phase 1 – the Western Route – stipulates construction of a gas transmission system from the Pisarevka CS (Voronezh Region) to the Russkaya CS (Krasnodar Territory). Intended to become the main compressor station of the South Stream’s offshore part and the most powerful one in the world, the Russkaya CS will be built in the Anapa District (Krasnodar Territory).
The Russkaya CS will be the Southern Corridor end point and the South Stream start point at the same time. Rated at 448 MW, the station will provide for building gas pressure up to 28.45 MPa. It will make possible to carry blue fuel 900 kilometers without any additional technical means.
