ABL Group Publishes Downloadable White Paper on Cable Protection System Failures

After a successful visit to Renewable UK’s Cables 2022 from October 18-20, ABL Group (including OWC, LongitudeINNOSEA and East Point Geography) published a white paper on cable protection systems and submarine cable failures.

According to 4Coffshore, approximately 4,600 submarine cables have now been laid and serve offshore wind farms around the world. Of the 4,600, about ten incidents are declared each year, resulting in an average unavailability of cables of 100 days. Over the past 7 years, 90 submarine cable failures have occurred, totaling over €350 million in insurance claims.

The challenges for the submarine cable connections are primarily determined by the environmental loads the cables are expected to withstand and increasingly large offshore installations, often with hundreds of connections, increase the overall probability of failure. The failure mechanisms are mostly well documented experimentally and the underlying physics is well understood, but not always applied correctly. The numerical modeling developed on these principles makes it possible to determine the risks of occurrence of these failures, supporting the evaluation and comparison of several corrective actions to reduce the risks.

In this article, our expert cable consultants, Riccardo Felici and Daniele Caruso, present the overall failure mechanism associated with Cable Protection Systems (CPS), outlining the methodologies that can be used to assess and prevent failures of underwire cables. sailors with particular emphasis on the transition section from the seabed to the offshore wind turbine foundation structure where most of the documented failures occur.

“ABL Group is involved in all stages of the submarine cable lifecycle for myriad wind farm projects around the world, and as such we recognize the importance of reviewing and assessing CPS systems to ensure risk mitigation and prevention of future cable failures.We are proud to present this study to continue a needed conversation and ultimately move towards a solution to these failure mechanisms, across the industry. ”
