APPLICATIONS

Applications

Eight application directions by industry: oil and gas pipelines, power cables, rail transit, urban utility networks, roads and bridges, perimeter security, mine safety, and offshore pipelines and wind power. Each lists monitoring scope and applicable conditions.

APPLICATION 01

Oil & Gas Pipelines and Energy Transport

Built on long-range, continuous distributed fibre sensing, this direction monitors trunk oil and gas pipelines, subsea pipelines and gas storage facilities online across the whole route — identifying third-party interference, media leakage and geohazard disturbance to keep the energy transport chain safe and stable.

Discuss this application

SCOPE

01 · Oil & Gas Pipelines and Energy Transport

Third-party disturbance identification and intrusion location along trunk pipelines
Acoustic signature recognition and precise leak location
Continuous sensing of landslides and ground subsidence along the route
Vibration acquisition and abnormal-condition detection at stations and valve chambers
Real-time alerting for anchor strikes and trawl damage on subsea pipelines
Surrounding rock stress and injection-production line monitoring for gas storage

APPLICATION 02

Power Cables and Line O&M

Sensing fibre is laid along power cable routes to give all-weather awareness of cable channels, cable tunnels and tower slopes, detecting mechanical damage, ground instability and unauthorised entry early — a reliable early-warning tool for cable operation and maintenance.

Discuss this application

SCOPE

02 · Power Cables and Line O&M

Excavation damage detection and precise location along cable routes
Distributed survey of voids and slip hazards in cable corridors
Vibration capture for cable tensioning and sheath damage
Slope instability monitoring at transmission tower foundations
Acoustic detection of unauthorised entry into cable tunnels
Discrimination of illegal heavy-machinery work along cable trenches

APPLICATION 03

Rail Transit and Tunnel Safety

For metro and railway tunnel structures and their protection zones, fibre acoustic sensing acquires vibration signals to cover structural defect detection, train condition awareness, external construction disturbance and security monitoring — protecting both the structure and running safety.

Discuss this application

SCOPE

03 · Rail Transit and Tunnel Safety

Distributed sensing of rock-mass and lining crack damage in tunnels
Rockfall and foreign-object intrusion warning along the track
Train passage vibration acquisition for wheel-rail defect detection
Monitoring and impact assessment of external blasting and deep excavation
Acoustic imaging of voids behind shield tunnel linings
Security sensing and warning for unauthorised entry into tunnel ancillary spaces

APPLICATION 04

Urban Utility Networks and Smart City

Aimed at urban lifeline infrastructure, distributed fibre sensing provides routine monitoring of utility tunnels, municipal pipe networks and underground space — enabling proactive discovery of underground risks and supporting safety management in smart cities.

Discuss this application

SCOPE

04 · Urban Utility Networks and Smart City

Operating-condition sensing of multi-compartment utility tunnel pipelines
Acoustic monitoring of abnormal leakage in municipal lifeline networks
Dynamic survey imaging of geological hazards in urban underground space
Intelligent identification and warning of construction work risks
City-wide security situational awareness of underground infrastructure
Alerting for unauthorised entry and rule-breaking work in municipal corridors

APPLICATION 05

Roads, Bridges and Transport Infrastructure

Sensing links are deployed on bridges, highways, slopes and highway tunnels to capture structural vibration, geotechnical disturbance and vehicle impact signals — integrating structural health assessment, geohazard warning and road event detection in one system.

Alerting for unauthorised entry over plant and station walls

APPLICATION 07

Mine Safety and Underground Works

Suited to underground mines, goaf areas, slopes and deep underground works, it acquires microseismic, blasting and strata-movement signals to identify rock instability, collapse and boundary-crossing excavation risks ahead of time, supporting mine safety control.

Discuss this application

SCOPE

07 · Mine Safety and Underground Works

Continuous acquisition and monitoring of microseismic rock-fracture events underground
