The project will bring together academic research institutes, an SME developing instrumentation, a rope supplier, a certification society and a floating wind platform designer to improve the reliability of station keeping of floating offshore wind turbines. First the project will develop in parallel both modelling tools for the mechanical behavior and long-term durability of nylon fiber rope moorings, and the monitoring instruments which will allow their in-service response to be assessed. These two aspects are critical to optimize the mooring system. They will then be evaluated by instrumented tests on a moored buoy at sea. In order to be as representative as possible of full-scale conditions (water depth and sea states), and to benefit from shared costs with the ABIOP+ project, the MISTRAL test site will be used. The present project will extend the TRL4 reached by the end of the POLYAMOOR project up to TRL7, thanks to results from a sea-trial demonstrator equipped with innovative sensors developed for in-service measurements. In parallel, this project will adapt the global mooring health monitoring strategy developed in the MHM-EMR project to this specific material.
