Advanced Acoustic & Thermal Monitoring
- Acoustic emission testing – sensors listen for sound waves generated by pressurised fluid escaping through cracks.
- Infrared thermography – thermal cameras detect localised temperature anomalies caused by evaporating fuel, revealing hidden leaks.
High‑Precision Inventory & Mass Balance Tracking
- Continuous level monitoring – high‑precision gauges track fuel volume entering and leaving the tank.
- Mass balance calculations – even minor discrepancies over time can indicate a slow, undetected leak, allowing early intervention.
Chemical Sensing & Tracer Gas Testing
- Tracer gas (e.g., helium) – pressurise the empty tank and use mass spectrometers to detect escaping gas molecules.
- Continuous vapour monitoring – installed in the interstitial space or surrounding soil to detect hydrocarbon vapours the moment they escape.
Physical Testing & Interstitial Monitoring
- Vacuum box or soap solution – applied to welds and seams to visually identify escaping air bubbles.
- Interstitial monitoring (double‑walled) – sensors in the gap detect liquid or pressure changes, providing immediate warning of inner tank failure.
