JSC Stroytransgaz was founded in 1990. The company started with the construction of facilities mainly for one customer – OAO Gazprom. The first project was a contract for construction of Almaznaya compressor station in the Perm Region. It was followed by contracts for development of Urengoy gas-oil-condensate field, Yamburgskoye field, construction of Yamal-Europe and Blue Stream gas pipelines, Zapolyarnoye field development.
