The overall objective of the FIBREGY project is to enable the extensive use of FRP materials in the structure of the next generation of large Offshore Wind and Tidal Power (OWTP) platforms by overcoming the above mentioned challenges. In order to achieve this objective, the project will develop, qualify and audit innovative FRP materials for offshore applications, elaborate new design procedures and guidelines, generate efficient production, inspection and monitoring methodologies, and validate and demonstrate advanced software analysis tools. Clear performance indicators will be designed and applied in the evaluation of two existing OWTP concepts to be re-engineered in FRP within the project. Finally, the different technologies generated in FIBREGY will be demonstrated by using advanced simulation techniques and building a real-scale prototype to validate the materials, tools, solutions, procedures and guidelines to be developed in FIBREGY.
