1 Subtitle Content Specialists in Remote Monitoring Benefits of Remote Synchronised Interruption What we have learned over the years Richard Williams I Sales Manager Slide: 1: #

2 Agenda 1. Overview of MERLIN Monitoring applications 2. Benefits of Remote Synchronised Interruption for above ground surveys 3. New benefits of Remote Synchronised Interruption 4. Lessons learned over the years Slide: 2: #

3 In The Beginning Transformer Rectifier Monitor Output Voltage Output current ON / OFF potentials at the TR Test Post Monitor ON Potential Instant OFF potential Coupon Current AC and DC measured Slide: 3: #

4 Remote Monitoring Advantages Proactive Cathodic Protection monitoring Increase in the effectiveness of Cathodic Protection Schemes Understanding of vulnerable points of the pipeline Reliable readings Compliance with HSE requirements Auditable recorded results using the CPSM database Slide: 4: #

5 Further Applications Sleeve Integrity Isolation Joints Critical bonds Sacrificial Anodes Nitrogen Filled Sleeve Monitoring Satellite communications for the TR Monitors icpsm Internet based Remote Synchronised Interruption. Slide: 5: #

6 Interrupting Pipelines For Above Ground Surveys Extremely time consuming Synchronised via Rugby Clock or internal circuit timing Battery failures Pipelines can be very long Unreliable method of synchronisation Slide: 6: #

7 Tackling The Challenges Time consuming methods. Permanently fitted Interruption solution No need to install unreliable standalone current switching devices Timing GPS Accurate to 1 m/s Battery failures Permanent installation Remote Switching icpsm Scheduled Interruption Solid State Relay Slide: 7: #

8 Software Features Slide: 8: #

9 Typical Installation Slide: 9: #

10 New benefits Pipelines will be in separate schemes Surveys carried out on smaller sections Slide: 10 : #

11 Example Network Picture of AGI with pipelines and TR s on each section Slide: 11 : #

12 Example Network Slide: 12 : #

13 New Advantages Interconnected CP system will allow the schemes to support each other Potential for less Transformer Rectifiers on the pipelines Potential for less ground bed installations Electrical connection of pipelines would not be typical Slide: 13 : #

14 Pipelines Electrically Connected Slide: 14 : #

15 Pipelines Electrically Connected Slide: 15 : #

16 New Concepts Deep well technology for ground beds More efficient ground beds Drill on Networks AGI Slide: 16 : #

17 Illustration Of Deep Well Ground Bed Slide: 17 : #

18 Deep Well Drilling At An AGI Content Slide: 18 : #

19 Reducing Challenges Land owner permission Landowner payments Third party agency payments Existing AC power Slide: 19 : #

20 What does this mean? Two distinct outcomes: Save Money! Up to 50% can be saved per installation Save time! Months can be saved in installations Slide: 20 : #

21 Lessons Learned by this GDN Eliminated monthly functional checks Conversion of Anode Systems Would require monitoring Cost savings to not visiting The data has to be managed effectively More issues have been realised and fixed Direct workforce can concentrate on more CP related tasks Slide: 21 : #
