Dynamic umbilicals for floating marine renewable energies technologies - Phase 2

Duration: 48 months (2018 - 2021)


Dynamic power cables have been clearly identified as critical components for floating ORE systems. High voltage alternating current (HVAC) cables for floating wind turbines are the main concern at this stage. An issue for the French industry is to identify the need for the construction, or the adaptation, of a test bench that would account for the inherent coupling between the mechanical, electrical and thermal loadings involved.


To experimentally characterise, model the constraints on dynamic cables and propose an in-service fatigue monitoring methodology.

Scientific and technical contents

  • Implementation of a test bench to characterise the behavioural laws of a dynamic cable and to validate the lifespan modelling of its components
  • Conducting of large-scale tank tests to confirm the hydrodynamic constraints to be considered in global simulation models
  • Use of these models to obtain the sensitivity of lifespan to the cable’s hydromechanical parameters
  • Testing of marine observation and measurement systems to periodically calibrate numerical models
