Challenge
Provide continuous monitoring of the dam’s structural integrity under seismic activity, water-level variations, and environmental stresses. Detect anomalies early to protect downstream communities and comply with regulatory requirements.
Solution
The project was implemented using the xDAS Sentry system, consisting of:
- 3 xWave triaxial digital accelerometers (9 channels total) to monitor vibrations and dynamic responses.
- xPlorer Premium with Voyager software as the central acquisition and data management module.
- Observer software suite for advanced Operational Modal Analysis (OMA), enabling engineers to track natural frequencies, damping ratios, and mode shapes under real operating conditions.
- FTP redundancy to automatically transfer measurement data to a secure remote server in Athens, ensuring reliable backup and continuous access even if local connectivity is interrupted.
Outcomes
The upgrade equips operators with continuous, high-precision vibration monitoring of the dam’s dynamic behaviour. The integration of Observer enables advanced OMA analysis for early detection of subtle structural changes, while FTP redundancy guarantees data security and long-term reliability in this remote mountain environment. Together, these measures enhance operational safety, support compliance, and ensure the sustainable operation of the hydropower facility.
