Measurements report

The measurement report will include the testing methodology and the results of the ocean sea trials of the 1:6 W2Power steel-based prototype with the FRP-based towers installed to hold the wind turbine generators. Considering that the trials will last 3-5 months, sets of data will be collected and analyzed to assess the metocean effects on the platform, ensure the technical feasibility of the towers in composites and validate the different monitoring systems developed in FIBREGY.In overview, the following industrial and technological achievements will be explained in the measurements report: 1st) guidelines for the installation of the FRP towers in the existing steel-based W2 Power prototype, 2nd) Installation of a SHM system based on accelerometers, strain gauges, and fiber optics in the FRP towers, 3rd) analysis of the results derived from the SHM system installed in the offshore platforms, 4th) conclusions regarding how useful are the obtained data for the digital twin model developed in WP3 to assess the structural integrity of the platforms, and 5th) analysis and conclusions of the influence of the metocean conditions in the structural integrity of the FRP-based towers installed on scaled W2Power prototype.
