TAILWIND-UP-HopOn will expand the existing knowledge on the design of station-keeping systems for floating wind energy on the Atlantic coast, making it publicly available to accelerate deployment. At present, only pilot projects have been implemented off the Portuguese coast, as large-scale infrastructures remain cost-prohibitive. Advancing knowledge to reassess and refine anchor system design methods and practices towards cost reduction is therefore critical. TAILWIND station-keeping technologies will be investigated with a focus on the specific conditions of the northern Portuguese Atlantic coast. The TAILWIND methodology will also be expanded by including different soil stress paths, scour analysis, and reliability studies. After the definition and characterization of the metocean and geotechnical scenarios including climate change, and the evaluation of the hydrodynamic response of selected technologies, TAILWIND-UP-HopOn will analyse the impact of vertical loads on the cyclic behaviour of soils subjected to multidirectional horizontal loading. The project will also assess whether scour and liquefaction of foundation soils, due to the vibration of mooring lines, significantly affect the performance of station-keeping systems for floating wind turbines. These inputs will be integrated into a numerical analysis of the soil-anchor system to identify new failure modes, reduce their associated risk, increase design reliability, and ultimately optimise its design. Integrating the data generated by the Hop On team with TAILWIND consortium outputs will contribute to the development of sustainable and efficient station-keeping systems for floating wind, tailored to the specific conditions of North Atlantic Coast. With this extension, the new TAILWIND project will impact the three main areas in Europe for offshore wind development: the North Sea, the Mediterranean Sea, and the Atlantic Ocean, while mobilising Portuguese excellence in a strategic area for the country.
