Context

Dynamic submarine cables, required to export the electricity generated by all floating ORE systems, are critical components subject to different and much more varied constraints than their static counterparts. Their in-service monitoring is therefore of paramount importance. Some technologies are used for monitoring subsea cables (DTS, DAS, Partial Discharge, etc), but they have limitations and may not be the most suitable for in-operation monitoring of dynamic cables.

Objectives

• To develop recommendations for the optimisation of in-service monitoring solutions for subsea cables at the farm leve
• • To propose a roadmap for the development of the identified promising technologies

Scientific and technical content

• Gathering feedback exprience on operating experience and experimental data on local failure modes (electrical, mechanical, thermal) of dynamic cables
• Identification of parameters reflecting the emergence of failure modes
• Identification of sensor technologies available or under development capable of detecting several of the failure modes
• Study of the best technological and economic strategies for the deployment of sensors to monitor the electrical cable network of a farm
