Gryazovets – Vyborg

The trunk gas pipeline Gryazovets – Vyborg is being constructed by SGM Group of Companies by order of LLC “Gazprom invest Zapad”. The gas pipeline is designated for supply of gas to the Nord Stream gas pipeline and to consumers of the North-Western region of Russia.

Total length of the gas pipeline is 917 km. The diameter of the pipe is 1400 mm. Operational pressure is 9.8 MPa. Design capacity – 55 billion m 3 of gas per year

In 2010 LLC “STROYGAZMONTAZH” completed construction of 300 km of linear part of the first gas pipeline string and n 2011 proceeded with construction of 700 km of the second string of the gas pipeline Gryazovets – Vyborg

Constructors had to solve a lot of complex technical tasks, in particular, in complicated geological conditions the crossings under the Neva and the Saima channel were performed with application of micro tunneling method


The longuest part of the route passed through swamps, the construction was made also in rocks, that is why explosive works were applied. Constructors had to solve a lot of complex technical tasks, in particular, in complicated geological conditions the crossings under the Neva and the Saima channel were performed with application of micro tunneling method

The project envisages construction of seven compressor stations on the Gryazovets – Vyborg gas pipeline. LLC “STROYGAZMONTAZH” is a contractor for construction of six of them: Gryazovetskaya, Sheksninskaya, Babaevskaya, Pikalevskaya, Volkhovskaya and Elizavetinskaya. The CS Gryazovetskaya, Babaevskaya, Volkhovskaya and Elizavetinskaya will be put into operation in 2011

It is planned that Gryazovets – Vyborg gas pipeline will reach its design capacity by the end of 2012.
