OMDYN

Dynamic cable for marine energy

Duration: 1 year

Project description

Unlike fixed bottom offshore wind, floating wind is characterized by the use of energy transport cable elements deployed between the seabed and surface, at the level of the wind turbine floating structure. These elements, called "dynamic cables", are several hundred meters in length and are subjected to motion from the floating support platform, waves and marine currents. They are also very sensitive to bio-fouling. The OMDYN project aims at developing the first elements of a response to specific industrial floating offshore wind needs concerning dynamic cables. These needs concern both cable design and operational monitoring. The OMDYN project, which is part of a larger research program, will permit the initial elaboration of a test bench dedicated to dynamic cables, and the definition of testing to be done in real conditions of an SHM method (Structural Health Monitoring) for medium and high voltage power cables.

Objectives

  • Estimate the mechanical characteristics of components
  • Numerical modeling of the global hydro-mechanical behavior of cables
  • xperimental characterization of thermo-mechanical fatigue
  • Monitoring throughout the cable life cycle
