Three reports investigating the issue of cable failure and design recommendations to mitigate risk have been published by the Offshore Wind Accelerator.
The offshore wind industry has identified cable failure as a high-profile and costly issue. In order to better understand this issue, the Offshore Wind Accelerator’s Cables Working Group commissioned the Fibre Optic Cable Protection Assessment project to validate earlier modelling and suggest design recommendations to mitigate risk.
The following three reports have been produced as part of this project:
The results of the induced voltage modelling concluded that a fibre optic cable can be designed to eliminate the type of fault that has been attributed to an interaction between the induced voltage on the cable and the sheaths of the power cores.
Five recommended design features for a fibre optic cable have been identified, along with proposed installation, inspection and monitoring actions. These are all outlined in the Design and testing recommendations report.
