Fiber-optic nerves for structural health monitoring

Fibre-optic nerves for structural health monitoring
Uninterrupted monitoring of stress and fatigue detects early signs of failure of large structures. The fibrisTerre system uses standard optical fibers used in everyday telecommunications – connected to a readout unit, the fibers become highly sensitive nerves within soil and concrete, sensing and transmitting data.

 

Pipelines

  • Detect possible failure at the earliest stage to prevent downtime and catastrophe
  • Detect geohazards (ground movement) along pipeline right of way
  • Monitor pipeline deformation
  • Optimize production efficiency
 

Geotechnical Engineering

  • Geotechnical monitoring of large and remote structures for early failure detection
  • Detect ground movement along railway lines, roads and embankments, pipeline and power cable rights-of-way
  • Detect settlement, subsidence, cracks and convergences
  • Detect threats to critical traffic links
 

Mining

  • Detect ground movement and strain in tunnels and shafts, during construction, in operation and in abandonment
  • Monitor conveyor belts and linear asset conditions
  • Monitor ground movement in tailings dams
  • Monitor strain in shafts and during tunneling
 

Civil Construction

  • Monitor bridges, dams, high-rise buildings
  • Measure deformation in concrete structures and diaphragm walls
  • Asses load and strain on foundation piles
  • Detect cracks and fatigue along beams, containments, cooling towers
 

Energy - Power generation and transmission

  • Optimize transmission: power cable temperature and strain monitoring over long and short distances
  • Detect hot-spots along onshore, subsea and offshore cable installations
  • Detect washout, scouring, and settlement along subsea cables
  • Monitor structural health of hydropower dams
  • Monitor nuclear waste storage facilities
 

Research and Development

  • Investigate fiber optic cable properties, including strain during cable jacketing
  • Get the insight to boost innovation in construction, electronics and photonics
  • Measure strain in power and fiber optic cable design and testing (fiber optic test and measurement)
  • Obtain live and continuous strain and temperature data for projects in earth science (geology, geodesy, hydrogeology, geotechnics)
  • Ideal for primary investigations and input or validation for models and digital twins
  • Feel what’s happening inside the fiber – state-of-the art Brillouin sensing
  • Walk new paths in cable design with online strain measurements
