Case Study
Subsea Architecture
Defective & decaying electrical system since installation 120mbd at risk if system fails Challenge: to remotely locate and isolate faults with minimum production disruption. Scenario
Connectors & interfaces
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 The challenge
The Solution
ROV Installation
Outputs & Displays
Growth in deepwater control deployment (Africa, Gulf of Mexico etc) Increased architecture complexity Ageing assets Opportunity to capture footprint signatures during installation. Market Opportunity
Full identification of subsea faults. Measurement of degradation over time. Change in Operator approach to risk; move reactive to proactive repair strategy. Benefits & Results
TDR functionality. OTDR options. Joint Industry Project. Collaborators required. Future product development
