OMDYN2

Dynamic onbilicals for floating marine renewable energies technologies - Phase 2

Duration: 3 years

Project description

Following the marine renewable energies (MRE) Technology Design Tools Program Working Groups organized by France Energies Marines (FEM) with its members and invited external developers, dynamic power cables have been clearly identified as critical components for floating MRE 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. While providing the necessary technical specifications, the methodological advances and analyses produced within the OMDYN2 project will contribute to making the most informed and appropriate investment decisions. The experimental campaign and specific validated numerical tools will also help in optimizing the design of these cables, contributing to the establishment of standards. This project is built upon the results of the OMDYN project, paving the way to a relevant experimental plan for this second phase, with associated well-defined costs.

Objectives

  • Experimentally characterize the electro-mechanical behavior of dynamic power cables
  • Provide for use validated numerical models for lifetime predictions
  • Take into account the constraints of biofouling
  • Develop a method to monitor fatigue life during operation
