Gascontrol Polska to inspect 154-km GAZ-SYSTEM network

Gascontrol Polska is set to begin 2026 with a significant project focused on pipeline integrity management. The project involves the comprehensive In-Line Inspection (ILI) of a 154‑km section of the 1,000‑mm (40‑inch) natural gas pipeline from Gustorzyn to Rawa Mazowiecka for the Polish TSO, GAZ-SYSTEM.

The project will be executed in collaboration with PIPECARE. The scope of work is divided into three key phases to ensure high-quality data collection. Initially, cleaning and calibration runs will be performed to verify the pipeline’s effective diameter and remove debris. This is followed by geometry and positioning inspection, utilising Above Ground Markers (AGMs) and DGPS to accurately locate physical deformations and irregularities. The final stage utilises Magnetic Flux Leakage (MFL) technology. This high-resolution diagnostic tool identifies metal loss, corrosion pitting, and other material discontinuities.

Upon completion, the project will deliver a comprehensive report featuring anomaly mapping, defect depth estimation, and prioritised repair recommendations (commonly referred to as dig-sheets). These findings will support GAZ-SYSTEM in its long-term integrity management and maintenance planning, ensuring the continued safe operation of this critical infrastructure.
