Distributed Acoustic Sensing (DAS) was used to detect various vibration sources along an active gas pipeline. The research team utilised diverse methods, including excavator and pick-up truck crossings, as well as human-induced actions (walking, digging with a spade or striking the ground with a fist).

The primary objective of the research was to compare the effectiveness of dedicated monolithic EpsilonSensors with existing telecom cables. Measurements were conducted through a direct connection near the test field and from 70 km using optical network as an extension.

The study used an interrogator Neubrex. Special thanks to Dr. Artur Guzik for his invaluable support.

Among many findings, it is worth emphasising that the use of an appropriate sensor increases the probability of detecting events and interpreting them correctly.

We sincerely thank the entire GAZ-SYSTEM team for their exceptional engagement and support throughout this project! Big thanks also to Szymon Długosz, Tomasz Howiacki and Łukasz Wzorek for their reliable work in the field.
