Supervision over the construction of the DN1000 Strachocina-Pogórska Wola gas pipeline along with the accompanying infrastructure necessary for its operation.

The Strachocina-Pogórska Wola gas pipeline is one of the final elements contributing to the North-South Gas Corridor program, a flagship investment of GAZ-SYSTEM S.A. The gas corridor plans include the implementation of a series of high-pressure gas pipelines connecting the Polish LNG terminal in Świnoujście with the planned Croatian LNG terminal, Adria, on the island of Krk. The North-South Corridor is one of the key investments in Central and Eastern Europe, listed in the Energy Infrastructure Package (EIP).

The gas pipeline, spanning 97.4 km, connects two nodes: the recently commissioned node in Strachocina (Sanok municipality) and the expanded node and gas compressor station in Pogórska Wola (Skrzyszów municipality). It traverses 13 municipalities (12 in the Podkarpackie Voivodeship and 1 in the Małopolskie Voivodeship). The pipeline will play a crucial role in developing fuel supply routes across Podkarpacie, potentially extending to Ukraine in the future.

The project involved supervision over the construction of a high-pressure gas pipeline. As part of the Strachocina-Pogórska Wola pipeline investment, MGGP S.A. supervised a series of specialized construction works, including:
– construction of a DN1000 gas pipeline, 97.4 km long, with an operating pressure of 8.4 MPa;
– 85 crossings using trenchless methods, including 9 DIRECT PIPE installations.
-microtunneling
– construction of Valve and Vent Assemblies (ZZU): Trześniów, Iskrzynia, Ustrobna, Sieklówka Dolna, Zawadka Brzostecka, Zwiernik;
– Pogórska Wola Node (regulating system, Valve and Vent Assembly (ZZU), universal sluice system, gas filter-separator assembly);
– construction of a fiber optic line
– welding works in challenging terrain - it should be emphasized that during the construction of the Strachocina-Pogórska Wola gas pipeline, for the first time in Poland, advanced technology for fully automatic welding was used - CRC Evans, method 135/135. This technology allows for automatic welding using six internal welding heads inside the pipe and four external heads. Special beveling is also used, reducing the amount of additional material used fourfold.

The construction of the gas pipeline reduces the operational costs of the transmission system by shortening the gas transmission route from imports. An important aspect is also the annual payment of property tax at a rate of 2% of the built transmission infrastructure located within the municipality, benefiting local residents.
