Electrical Fault Detection
Detect, localise and respond to electrical faults in real time to minimise downtime.
ABOUT Electrical Fault Detection
Detection of electrical faults to minimize cable downtime
Electrical faults in subsea power cables can occur suddenly and without warning. From insulation failures to connector breakdown, even minor issues can result in full transmission loss. Without a reliable detection method, operators risk costly downtime, and cannot easily plan repair campaigns.
Why Electrical Fault Detection matters
The challenge of undetected electrical faults
Unlike anchor drops, electrical faults are often silent until a failure occurs. Traditional inspection methods can be slow and reactive, leaving operators blind to issues developing deep underwater. Proactive fault detection is essential to reduce downtime and protect project timelines
Monitoring benefits
We take care of your
submarine power cables.
Detects and locates faults early
Identifies electrical anomalies in real time over the full cable length, allowing intervention before it escalates into critical failures.
Reduces Mean Time to Repair (MTTR)
Pinpoints fault locations quickly, enabling faster mobilisation of repair teams and minimising operational delays.
Improves safety and reliability
Prevents high-voltage risks by detecting faults early, supporting safer working conditions and more stable power delivery.
Minimizes downtime and penalties
Avoids extended outages that can lead to production losses and financial penalties.
Continuous, Real-Time Monitoring
24/7 monitoring ensures no anomaly goes undetected, providing operators with confidence in their asset integrity.
Integrated into the Marlinks dashboard
All fault data is visualised in one platform alongside other monitoring modules, enabling efficient diagnostics and decision-making.
How it works
Detect electrical faults before failure occurs
Marlinks’ electrical fault detection module uses Distributed Acoustic Sensing (DAS) and fiber optic technology to monitor electrical signals and detect anomalies. Integrated into our subsea cable monitoring platform, this system provides early warnings and precise fault location, enabling faster response and repair.
Our system is designed to work across both AC and DC offshore transmission networks and can be combined with other Marlinks monitoring modules for complete cable health insights.
All monitoring data is visualised in the Marlinks dashboard, giving operators a clear, real-time overview of cable behaviour across the entire route. This enables faster decision-making, smarter interventions, and full integration with other monitoring modules.
