STROYGAZMONTAZH to build more than 300 km at the Gryazovets – CS Slavyanskaya section
20.08.2018
STROYGAZMONTAZH is responsible for the construction of more than 300 km within the framework of the construction project "Development of gas transportation capacities of the UGSS of the North-West region, Gryazovets – CS Slavyanskaya section."

The customer is Gazprom Invest; the general contractor is STROYGAZMONTAZH; the subcontractors are: Lengazspetsstroy, Krasnodargazstroy, Gazregion, Neftegazkomplektmontazh and Construction and Manufacturing Group Nauka.

2 strings of the main gas pipeline with a diameter of 1400 mm will be laid on the section "538 km - 852.7 km" and 4 strings 800 mm in diameter at the section "852.7 km - 859.5 km" (from the compressor station Slavyanskaya to the coastline).

8 crossings of the Mertvitsa and the Luga rivers on the section "852.7 km - 859.5 km" are particularly difficult, as they will be built by the HDD method. Crossings of the Volkhov, the Tigoda and the Oredezh rivers will be carried through underwater technical operations.

The construction of the gas pipeline employs about 1800 people and about 800 units of construction equipment. Currently, clearing of the route from the forest is being completed, the pipe is being welded into the string, the trench is being developed and laying and burial of the pipeline is underway.
