Protect against offshore wind cable failures with A new approach to subsea cable monitoring

ECG™ holistic cable monitoring system

Proserv and partners have developed a new and unique system methodology for subsea cable monitoring and fault detection that applies to export and inter-array cables within offshore wind farms.

ECG™ introduces a step-change in traditional monitoring methods, offering comprehensive visibility across cable assets. Adopting an integrated and scalable approach, ECG™ provides real-time analysis with insights through an intuitive user interface. Enabling proactive decision-making, improving utilisation and reducing OPEX costs, ECG™ delivers complete peace of mind.

Proserv understands the specific industry challenges that are related to monitoring cables, cable faults and the cost of failure on cable assets. This knowledge, complemented by our offering of leading controls technology and integrated solutions, best places Proserv to provide this innovative and unique approach to monitoring cables.

Are you counting the cost of cable and termination failures on your wind farm?
It costs £12.5m to repair a single failed export cable and £8.4m to repair a single failed inter-array cable
75-80% of insurance claims by offshore wind industry are for subsea cable failures

Protect your cables and stop faults from occurring

Subsea cable and termination faults are common, but they can take a lot of time and money to fix. ORE Catapult data shows that they are responsible for 75-80% of the total cost of offshore wind insurance claims. Compounded over the 30 year life of the wind farm, the potential liability could spiral to £25m for inter-array cables and £292m for export cables* – and that’s not including lost power generation.


The issue is that traditional monitoring methods such as ROV inspections or isolated sensors will not help to mitigate these costs, as they are reactive and can only offer an isolated view of an individual fault. Worst still, standard inspections can miss crucial faults on joints and terminations, and any warning signals that a problem has occured comes too late.


Scalable fault detection throughout the wind farm

ECG™ offers operators better visibility and understanding of the live condition of cable assets, empowering decision-making through the insights generated from data analytics, so alleviating the requirement for physical O&M inspections and the CO2 footprint of unnecessary journeys. By combining Synaptec‘s sensor technology and BPP Cable Solutions machine learning and AI capabilities, ECG™ represents a paradigm shift in automated condition monitoring, enabling small anomalies in performance to be detected long before a problem arises.


Our solution employs a unique non-intrusive passive monitoring technology, enabling multiple sensors to be deployed throughout the wind farm, thus creating a multiparameter sensing network, and with measurements provided at a central location. With Synaptec‘s passive sensor arrays, ECG’s sensor technology requires no power or data networks and provides live data more reliably and securely from more locations. This wide area, multipoint technology is ideal for automated condition monitoring, and improved asset management decisions.

Intuitive visualisation for easy insights and action

Traditional HMIs prioritise the visualisation of equipment over the visualisation of data.As a result, they cannot cope with today’s growth in data.
