Freespan Monitoring
Track dynamic cable movement to prevent damage and extend cable life.
Real-time insights into cable movements.
Subsea power cables of floating wind farms are exposed to continuous external drivers of movement such as waves, currents, floater movement, and seabed mobility. Over time, this dynamic environment can cause cable fatigue or extreme loads. Without proper monitoring, these dynamic cable risks remain hidden, potentially leading to early cable failures.
Hidden stress in dynamic environments.
Too much bending can damage the cable, particularly at critical points like cable exits and entry zones. Understanding how and where cables move is essential to maintain asset integrity and prevent faults.
Moreover, dynamic cable systems are not mature yet, and their long-term behaviour under real-life offshore conditions is not yet fully understood. Continuous monitoring not only helps operators protect existing assets but also provides valuable data to designers and engineers. These operational insights support the improvement of future cable designs by offering a clearer understanding of actual exposure to movement and stress.
We take care of your subsea power cables.
Detect stress zones
Continuously quantifies the cable’s movement to identify areas where it is experiencing bending. These are key indicators of stress that could lead to damage over time.
Enable preventive maintenance
Provides early warnings of abnormal movement patterns, allowing operators to intervene before issues escalate into costly failures or outages.
Minimizes fatigue-related failures
By tracking dynamic forces acting on the cable, the system helps reduce the risk of long-term damage caused by vibrations or repetitive stress.
Get real-time insights
Delivers both live alerts and long-term performance data, giving asset owners a clear view of how cable behavior evolves over time and under varying environmental conditions.
Integrated into the Marlinks dashboard
Seamlessly connects with other Marlinks modules, offering a single, user-friendly interface for monitoring services, all in one place.
Supports asset management
Use data-driven prioritization of inspection and intervention campaigns, helping optimize resources and extend asset lifetime.
From cable movement to actionable insights
Marlinks’ dynamic cable monitoring solution tracks real-time cable movement and vibration patterns using Distributed Acoustic Sensing (DAS) and fiber optic sensing technology. Our system detects abnormal patterns and stress conditions before they escalate into damage. The Marlinks monitoring system provides accurate and actionable insights to reduce risk and extend the cable lifespan.
All monitoring data is visualised in the Marlinks dashboard, giving operators a clear, real-time overview of cable behaviour across the entire cable route. This enables faster decision-making, smarter interventions, and full integration with other monitoring modules.
