Localize and monitor unstable Cable Protection Systems (CPS).

cable protection systems (cps)

Offshore wind farms have rapidly emerged as a critical component of the global transition towards cleaner and more sustainable energy sources. With their ability to harness the immense power of offshore winds, they provide a significant contribution to reducing carbon emissions and meeting energy demands. However, the challenging offshore environment, characterized by harsh weather conditions demands meticulous maintenance and monitoring strategies to ensure the optimal functioning of various components. One such crucial element is the Cable Protection System (CPS) in the offshore wind farm.

Cable Protection Systems (CPS) in offshore wind farms

Cable Protection Systems (CPS) play a vital role in offshore wind farms by safeguarding the network of subsea power cables that transport electricity to onshore grids. The CPS systems are shells that protect the exposed cable from seabed to monopile. Given their underwater exposure and the dynamic nature of the marine environment, the shells of a CPS are very vulnerable. Swinging or scraping against the rock bottom surrounding the monopile can damage the CPS, placing the subsea cable at risk. A failure or malfunction of these cables can lead to significant downtime, resulting in high repair costs, and operational inefficiencies.

Introducing Distributed Acoustic Sensing (DAS) to check the CPS status

Distributed Acoustic Sensing (DAS) technology represents a groundbreaking innovation in monitoring and surveillance. DAS systems convert standard fiber optic cables (embedded in the power cable) into an array of highly sensitive acoustic sensors. By analyzing the backscattered light along the fiber, DAS devices can detect vibrations and acoustic signals, enabling the observation of real-time activities along the length of the subsea cable. In this way, it is possible to track the current status of a CPS.

What are the advantages of continuously monitoring an wind farm’s CPS’ with DAS

Integrating DAS devices into CPS monitoring strategies in offshore wind farms offers an array of benefits:

  1. Early detection of threats: DAS devices can pick up subtle changes in cable vibrations, detecting potential threats such as scraping or swinging. This early warning system helps operators respond timely to prevent damage.

  2. Comprehensive coverage: The ability of DAS devices to provide continuous monitoring along the entire length of the cable provides a level of coverage that traditional monitoring systems struggle to achieve.

  3. Reduced downtime: By promptly identifying and addressing issues, CPS Monitoring systems minimize downtime associated with cable repairs and replacements, ensuring a steady power supply.

  4. Data-driven maintenance: DAS-generated data allows for predictive maintenance scheduling, enabling operators to address cable vulnerabilities before they escalate. Get generated insights via a dashboard or reports.

  5. Cost efficiency: The proactive approach to maintenance and the reduction in repair-related expenses contribute to overall cost savings in offshore wind farm operations.


Optimizing the performance and reliability of offshore wind farms remains a high priority. The integration of Distributed Acoustic Sensing (DAS) devices into an overall remote monitoring strategy shows the innovation driving the industry forward. By using the power of fiber optic technology, wind farm operators can proactively safeguard their subsea cables, contributing to increased efficiency, minimized downtime, and a more sustainable energy future. As the technology continues to advance, subsea cable monitoring solutions are destined to play an important role in offshore wind farm management strategies.
