  1. 1. Using Omnisens’ DITEST SystemSamer NajjarArea Sales Manager, EMIOctober 4th 2011
  2. 2. Agenda EMI + Omnisens Pipelines Technology Omnisens DITEST Summary Q&A 2
  3. 3. Engineering & Marketing Int’l Founded in 1992 HQ in Los Angeles, CA Offices in Beirut, Bahrain 15 employees Bring Latest Technology to the Middle East  SmartSignal  OSIsoft  Omnisens 3
  4. 4. Omnisens Privately-owned Swiss company, established in 1999 Spin-off from Swiss Federal Institute of Technology in Lausanne Headquarters in Morges, Switzerland Backed by VINCI Capital since 2008 30 highly educated employees Worldwide customer base 4
  5. 5. Pipelines Critical network & Lifeline Millions of kilometers Various terrains Wide range of products:  Oil  Gas  Water  Sulfur/Chemicals 5

  10. 10. Distributed Sensing Distributed sensing is based on the analysis of light scattering Scattering originates from inhomogenities in silica Scattering modifies the spectrum of the incident light 10
  11. 11. Brillouin, Rayleigh, Raman Scattering medium Scattering processes used for sensing Laser, lo applications:Rayleighdetection and analysis of fastintensity variations acousticsignal detection.Ramanscattered magnitude istemperature dependentBrillouinlines are temperature andstrain sensitive 11
  12. 12. Brillouin Distributed Sensing Hot spot Uniform temperature Analysis of the backscattered light Use of pulsed light enables localization Optical fiber Spectral analysis of the scattered light provides the Temperature and/or Strain information 12
  13. 13. Brillouin Brillouin-based distributed sensors exist in two versions: BOTDR BOTDA Brillouin Optical Time-Domain Brillouin Optical Time-Domain Reflectometry Analysis BOTDR is based on the spontaneous BOTDA is based on the stimulated back-scattered light (linear) scattering • Single fiber end access vs of light (nonlinear) • Requires frequency processing at the • Two-fiber loop configuration – two fiber detection ends access • Weak signal, long averaging times • Strong signal, reduced averaging times • Longer distances capabilities and faster acquisition times 13
  14. 14. Omnisens DITEST One single laser 2008 Global Fiber Optic Sensors & Customer Value Innovation of the Year Award Pump and probe signals generated by optical signal processing 14
  15. 15. Advantages of DITEST One single laser source Automatic compensation of drifts Flexibility in the generation of optical signals (pump and probe intensity adjustments) Enhanced signal to noise ratio Long distance capabilities Large optical budget (> 10dB in standard, custom unit > 20dB upon request) 15
  16. 16. Advantages of DITEST Standard single-mode fibers 1550nm wavelength Brillouin scattering – frequency-based technique – intrinsically stable Stimulated Brillouin Scattering - BOTDA Single laser source setup  Pump and probe generated from the same laser source  Self compensation of drifts  Long-term stability 16
  17. 17. Advantages of DITEST Improved Signal-to-Noise ratio – Higher Optical Budget Performance maintained over long distances – Short acquisition time – Long distance range >50km – Short spatial resolution down to 1 m – Excellent measurement resolution (0.5°C and 10mε) Frequency-based technique – Long term stability and reliability, not sensitive to attenuation drifts or loss Uses standard single-mode fibers 17
