Within the framework of the COREWIND European project, IHCantabria have successfully finished the ambitious large-scale tests campaign of two novel concrete-based concepts: WindCrete and ActiveFloat. For the last three months, more than 120 experimental tests including fully coupled wave-current-wind testing as well as installation testing, have been conducted on both floating platforms in the Cantabria Coastal and Ocean Basin (CCOB) facility at Environmental Hydraulics Institute of the Universidad de Cantabria.
The seakeeping tests on the novel floating offshore wind spar-based concept, WindCrete, designed by UPC School (Universitat Politècnica de Catalunya) have been carried out at a scale 1:55. On the novel semisubmersible-based platform with active ballast, ActiveFloat, developed by Grupo Cobra and Esteyco, the tests campaign has been made at a scale 1:40. The outcome results validate the COREWIND achievements and will contribute to mature innovative concrete-made solutions called to untap European offshore wind potential.
