Scenario

• Defective decaying electrical system since
  installation
• 120mbd at risk if system fails
• Challenge to remotely locate and isolate faults
  with minimum production disruption.

The challenge

• Develop system to electrically test integrity of
  subsea power and control umbilicals
• Provide data logging for reference
• To isolate faults in subsea architecture
• Enable fast accurate repair

Market Opportunity

• Growth in deepwater control deployment (Africa,
  Gulf of Mexico etc)
• Increased architecture complexity
• Ageing assets
• Opportunity to capture footprint signatures
  during installation.

12
Benefits Results

• Full identification of subsea faults.
• Measurement of degradation over time.
• Change in Operator approach to risk move
  reactive to proactive repair strategy.

13
Future product development

• TDR functionality.
• OTDR options.
• Joint Industry Project.
• Collaborators required.
