Distributed Fiber-Optic Sensing in Geotechnical Engineering and the Energy Sector
Friday 9 June 2023 | Room Lehar 3
Convenors
- Mahmoud Farharidoushan (Silixa)
- Nils Noether (fibrisTerre Systems)
Description
Distributed fiber-optic sensing refers to a family of technologies that enable asset owners and operators to retrieve vital data from within structures over long lengths and at high rates and resolutions. Optical fibers, deployed as sensors over tens of kilometers, can deliver data on acoustics, static and dynamic strain, temperature and many other properties that contribute to efficacy enhancement in production and exploration, as well as risk management during construction and operation – of tunnels and roads, boreholes and wells, slopes and embankments, and any other element of today’s critical infrastructure.
The one-day workshop will focus on practical insights from successful monitoring projects, sharing hands-on experience on installation, operation and data handling. The workshop will bring together application specialists from industry and academia with anybody who wants to learn how to use this powerful technology.
Sub-Topics that will be covered in the workshop:
Hands-on interactive workshop:
- Overview of different DFOS technologies (acoustic, static and dynamic strain, temperature)
- Introduction to optical fibers dedicated to sensing applications
- Choosing the right cable design and installation technique for your application
Bringing together the industry, academia and the technology providers:
- Invited presentations sharing practical insights from successful monitoring projects
- A panel discussion with researchers and application experts on the capabilities and challenges of distributed fiber-optic sensing
Participant Profile
Everyone from the industry or academic world who would like to learn or deepen their knowledge – about the use of different DFOS technologies in geotechnical, geophysical, structural and civil engineering in energy transmission or other fields.
