1. 1 Through Wall Communication Revolutionises Pig Tracking By Gordon Blair, UK Sales Manager, TDW Offshore Services PPSA, Aberdeen 19/11/2008

2. 2 Contents Why pig tracking? What are the options? SmartTrack system benefits Field Examples & Applications SmartTrack product series Summary of application Conclusion

3. 3 Why pig tracking? For detection and location of pigs in pipelines. Tracking is the most efficient way: –to be able to locate stuck pigs in a pipeline. –to detect pigs and confirm a pig has passed a valve to be closed, or to confirm a pig has arrived in the receiver. What are the Options? Radio active source No battery life issues but handling issues Transmitters (“Pingers”) Battery life issues vs frequency/signal strength Inflexible once in the pipeline

4. 4 SmartTrack™ System Advantages: Unique ID and Play Back Each pig is given a unique ID, so that the location of each pig in a multiple pig train can be identified. Data can be recorded for later playback If a pig is missed by the operator then replay to be sure of where you are!

5. 5 SmartTrack TM Advantages The output power of the SmartTrack TM transponder is adjustable at any time during a project to optimize battery lifetime, pigging speed, burial depths and positioning accuracy. Unit can be put into dormant mode for elongated periods then re- awakened remotely to allow continuation of the operation Pig Tracking with SmartTrack™ allows complete operational flexibility. SmartTrack™ fits into your plan & does not dictate it.

6. 6 SmartTrack™ Advantages Monitors multiple pig tracking locations without the need to move subsea tracking systems or require multiple vessels Wireless communication between the subsea receiver and the platform or vessels The system tracks pigs subsea, topside, and in onshore buried pipelines Positioning accuracy of  5cm (2in)

7. 7 SmartTrack™ Advantages Signal strength, transponder speed, and ID can be changed while the transponder is in the pipeline The SmartTrack TM system can be put into stand-by mode inside the pipeline and transponder battery lifetime can be extended greatly.

8. 8 SmartTrack™ Pig to Vessel Communication SmartTrack parameters can be changed from the vessel. Frequency, power level, sleep mode and interrogation of deployed sensors (e.g. pressure) can all be set remotely Acoustic Modem

9. 9 In Line Monitoring SmartTrack can be used to monitor pipeline parameters (such as pressure), and allow interrogation from the vessel. Offers active monitoring of pressure and pig location during applications (such as pipeline isolation with a high friction pig train)

10. 10 SmartTrack™ High Friction Pig Train SmartTrack™ utilised to confirm individual pig position and the pressure across each high friction isolation pig. Real time monitoring throughout the operation.

13. 13 SmartTrack Transponder D116 / D76 Applications Tracking, location and identification of pigs inside pipelines. Mounted on the pig, preferably centered with the antenna end outside any metal pig body.

14. 14 SmartTrack Topside Transceiver Applications Locate, track, and identify pigs with SmartTrack transponders Communicates with a handheld computer using Bluetooth wireless Can be used topside or on land Positioned parallel to the pipeline for general use or perpendicular for pinpointing

15. 15 SmartTrack Remote Transceiver Applications Locate, track and identify pigs with SmartTrack Transponders. Connected to laptop computer via cable. Can be used stationary sub sea / topside / land or carried by ROV swimming along the pipeline. Positioned parallel to the pipeline for general use or perpendicular for pinpointing.

16. 16 SmartTrack Diverheld Receiver Applications Locate, track and identify pigs with SmartTrack Transponders. Normally diver operated, but can be handled by a ROV. Positioned parallel to the pipeline for general use or perpendicular for pinpointing..

17. 17 SmartTrack PDA Applications Locate, track, and identify pigs with SmartTrack transponders Communicates with the SmartTrack Topside Transceiver using Bluetooth. Can be used topside or on land

18. 18 Typical use / pig passing 312 1 2 3

19. 19 Acoustic Transducer Modem & batteries Remote Transceiver SmartTrack TM Subsea Communications Skid The primary application for this system is wireless offshore pig tracking during projects that otherwise require the vessel to be moved or vessels to be added.
