Kovykta–Sayansk–Irkutsk gas pipeline
In 2006 Stroytransgaz signed a contract as general contractor for construction of the Kovykta–Sayansk–Irkutsk gas pipeline. The East Siberian Gas Company is customer for the project.
In accordance with the contract, Stroytransgaz is building the main gas pipeline from the Kovytka gas-condensate field to the Zhigalovo residential area (Kovykta–Zhigalovo) and all associated infrastructure. The pipeline will stretch 112 kilometers; its main line will have a diameter of 720 millimeters.
Specialists from the company will have to overcome sections of permafrost soil during construction of the gas pipeline. The project is also distinguished by simultaneous construction at three points along the route: laying of pipeline from Zhigalovo and from the Kovykta field and building underwater crossings across the Lena and Tutura rivers.
The project was completed in 2007.
