    1. Sensornet Monitoring Solutions

    3. Sensornet Ltd Background

    4. Sensornet Ltd Established 1998 Offices in; London, UK – Head Office Dubai, UAE Calgary, Canada Kuala Lumpur, Malaysia

    5. Sensornet Ltd Manufacture and deploy DTS into the following sectors; Downstream Process Leak Detection for Midstream and Downstream (refinery and transportation pipelines) Vessel Monitoring Hotspot Monitoring Oil & Gas Downhole (Upstream) applications for well integrity and flow profiling Power HV power cable monitoring Hydro Dam Monitoring Environmental Monitoring

    6. Leading Bluechip Customers

    7. Distributed Fibre Optic Sensing Technology Principle

    8. Principle of Measurement

    9. The Fibre is the Sensor

    10. Time of Flight Principle

    11. Pipeline Leak Detection

    12. Operator Issues with Leak Detection When are leaks occurring? DTS can detect leaks instantly 10 second measurement time - leaks detected before environmental damage or safety incident Current leak detection can’t pinpoint leak locations With Digital Leak Detection – leak is located to within metres – find instantly – low excavation costs Costly inspection programs can be reduced Leak detection is intrusive and can delay operations Digital leak detection non-intrusive, no delay to production – no risk to pipeline

    14. Gas Leak Detection

    15. Fluid Leak Detection

    16. Heat Trace Monitoring

    17. Temperature Control Using DTS

    18. Full Pipeline Coverage using DTS No limit to number of DTS acquisition units

    19. Intelligent Alarms Define up to 500 zones per Channel Alarm Criteria Fibre break Temperature exceeds value Temperature lower than value Temperature exceeds rate of change One point exceeds average value in zone

    20. Vessel Monitoring

    21. Vessel/Tank Monitoring

    22. Installation Methodologies Sensing cable can be looped to form zones

    23. Zone Alarms

    25. Field Trials Leak Detection

    26. Gas Pipeline Leakage Test

    27. Gas Pipeline Leakage Test

    28. Water Pipeline Leakage Test

    29. Third Party Interference Detection Cobalt Pipeline Security Solution

    31. Operator Issues with Third Party Interference What interference is occurring? Cobalt system can detect and identify Human movement within 10mtr Mechanical equipment within 100mtr Where is it occurring? 10mtr spatial resolution can detect location and indicate direction of movement False alarms Acoustic signatures and baseline readings are configured to minimise false alarms. All events can be aurally monitored Tests and evidence Recent European test detected 49 out of 50 potentially intrusive actions. This is the highest number achieved. Updates Intelligent system will allow user to configure known equipment signatures

    32. Intruder Detection

    33. Geographical Display

    34. Remote Facility Security

    35. PIG Monitoring Monitor PIG movement through pipe via acoustic signature Enables PIG recovery Detect hydrates by PIG speed

    36. Field Trials Third Party Interference

    37. Approvals Extensively Tested by AT&T NUWC NSA US DoD GERG Test facility in West England

    38. Pershore Tests - Walking

    40. Strain Monitoring Geotechnical Movement and Pipe Monitoring

    41. Geotechnical Strain Monitoring Strain cable installed adjacent to Pipeline can detect ground movement caused by; Seismic movement Landslides Ground erosion Third party interference

    45. Sensing Cable Specification and Location

    46. Typical Cable Specification Optional supply of cable containing Sensing and Communication Fibres

    47. Cable Location

    48. Conclusion

    49. Optical Sensing Systems Single optical cable can be used for; Pipeline leak detection Third Party Interference Strain Monitoring Plus Vessel Monitoring (hotspot & leak) Perimeter Security PIG location
