Dynamic cables for floating ORE systems


Latest progress of the OMDYN2 project

Last week, OMDYN2's partners met at Ifremer's North Sea Channel Centre. This project is concerned with the experimental characterization and modeling of stresses on dynamic cables in floating EMR systems.
The meeting was an opportunity to review recent work:

  • development of 2 local 3D models, at different levels of refinement, for predicting the fatigue of critical internal cable components and modelling friction between the various internal components;
  • preliminary mechanical tests on a test bench, at different operating temperatures, to qualify the viscoelastic behaviour of the dynamic cable used in OMDYN2. The results obtained will notably be used to validate local models;
  • 1st series of hydrodynamic tests on a scale of 1 allowing a detailed understanding of the viscous effects induced by the presence of biofouling. After tests on smooth cylinders, the tube was covered with sections created by 3D printing representing moulds positioned in various orientations, based on statistical analyses of observations made at sea on mooring lines.
