Pipeline Leak Detection
Real-time leak localization within 5 m accuracy
Monitoring solution
Multi-parameter fiber sensing for oil, gas and energy assets.
Intrinsically safe multi-parameter fiber optic monitoring for oil rigs, pipelines, downhole production logging, mining subsidence, and power grid assets — leak detection, structural integrity, and thermal profiling from a single sensing platform.
The engineering question
What must be observed before failure becomes visible?
Oil and gas assets — platforms, pipelines, wells, and refineries — operate in the most demanding environments on earth: high temperatures exceeding 200°C, extreme pressures, corrosive chemicals, and explosive atmospheres. Electronic sensors introduce ignition risk and degrade rapidly under these conditions, requiring frequent replacement and creating dangerous maintenance windows that expose personnel to hazardous zones.
Energy assets span vast geographic areas — hundreds of kilometers of pipelines, remote wind farms, and offshore platforms — where wired electronic systems are impractical and battery-powered wireless sensors have limited operational life. Pipeline leaks go undetected for hours or days using traditional flow-balance methods, costing millions in lost product and environmental damage. The industry requires a sensing technology that is intrinsically safe, corrosion-free, capable of multi-kilometer range, and provides continuous real-time leak detection, structural health monitoring, and thermal profiling without maintenance intervention.

Sensing chain
Treat sensing, interrogation and interpretation as one system.
The energy asset monitoring system combines multiple fiber optic sensing modalities into a unified deployment:
Pipeline Leak & Intrusion Detection: uwDAS fiber buried along the pipeline right-of-way continuously monitors acoustic signatures. Real-time algorithms distinguish between normal flow noise, pigging operations, excavation activity, and leak-generated acoustic emissions — localizing events within 5 meters. Complemented by UW-DTS fiber for thermal leak detection, the system achieves sub-5% flow-rate sensitivity through negative pressure wave analysis.
Downhole Production Logging: UW-DTS fiber deployed behind the well casing provides continuous distributed temperature profiling along the entire wellbore, enabling zonal flow allocation, gas lift monitoring, and steam injection profiling without intervention — critical for optimizing production from multi-zone completions.
Offshore Platform & Subsea Integrity: UW-FBG strain sensors bonded to critical platform members, risers, and subsea structures deliver real-time structural health data. The corrosion-free, EMI-immune fiber sensors eliminate the need for underwater electronics and provide 25+ year service life for subsea installations.
Mining Subsidence & Power Grid: UW-FBG surface strain arrays track ground displacement above active mining zones with sub-mm precision, while UW-DTS fiber on power cables and transformer windings provides continuous thermal monitoring for grid asset management. All sensor data converges at the RS-series interrogator and the Ray-Sensor platform for centralized visualization, automated alerting, and SCADA integration.
