FEBUS DTS, DAS, DSS – FIBER OPTIC

New generation of optical fiber based sensor system for the maintenance and monitoring of infrastructures

The patented technology uses state of the art optical physics to measure temperature, strain and vibrations of a structure or soil over tens of kilometers.
Distribuited Fiber-Optic solutions allow monitoring the integrity of infrastructures such as pipelines, umbilicals, wells, power cables, civil engineering structures, perimeter intrusion detection, or transportation infrastructure monitoring.
The technology uses innovative optoelectronic architecture and unique HPC (High Performance Computing) signal processing algorithm to measure accurately temperature, strain and vibrations over tens of kilometers. Robust and easy to use, Febus Optics devices are fully “plug and work”.

STRUCTURAL HEALTH MONITORING
Ageing management of large scale structures, such as Nuclear Power Plants, Tunnels or Dams is a key issue for infrastructure owners. With little investment on monitoring with distributed sensing, lifetime can be significantly increased,security improved, and maintenance costs reduced.

FEBUS G1-R, G1-C, G1-D, as DSTS systems (Distributed Strain and Temperature Sensing) offer a large panel of monitoring possibilities with respectively: high sensitivity, low consumption and dynamic sensing. Real-time monitoring can also be a critical asset, especially for transportation facilities such as railways or viaduct.

For these applications, FEBUS A1 (Distributed Acoustic Sensing system) can be a precious monitoring asset for vehicle localization, axle failure detection or Eigenmodes frequency determination.

PIPELINE MONITORING

FEBUS A1 (DAS: Distributed Acoustic Sensing) and FEBUS G1-R (DTS: Distributed Temperature Sensing and DSS: Distributed Strain Sensing) products, bring an integrated Pipeline Integrity Monitoring Solution (PIMS) by merging strain, acoustic and temperature measurements in one single mode fiber optic cable.

FEBUS OPTICS PIMS (Pipeline Integrity Monitoring Solution) ensure a real-time, permanent and simultaneous detection, every meter along several tens of kilometers, of the following events:

  • Gas and oil Leak detection;
  • Geo-hazard detection such as landslides, mudslides and earthquakes;
  • Third Party Interference such as manual excavation, hot tapping, third-party excavation, heavy machine movement, position and scrap tracking as well as agricultural activities.

CABLE INTEGRITY MONITORING

Power Cable related incidents account for 80% of insurance claims and around 60% relate directly to cable damage during construction of offshore windfarm. Thus, cable monitoring is becoming essential. FEBUS G1-R, G1-C, G2 (DSTS) and A1 (DAS) bring not only temperature monitoring over very long distance, RTTR (Real Time thermal Rating), shock and vibration monitoring but also a unique real time integrity monitoring during each phases of the cable life cycle: transportation, transpooling, deployment and operation.It is now possible to monitor the bending radius, tension and traction of the cable during installation as well as fatigue for dynamic cable.
