Result 1:
Deliverable 1.1 is related to the scenarios definition, including location, floater and mooring configurations, as well as the estimation of loads expected for mooring lines and anchors in selected scenarios.
These loads in mooring lines and anchors are required for the research activity being developed in other project activities, WP2 ‘Mooring line technology’ working on the mechanical characterisation of fibre ropes used in the mooring lines, and WP3 ‘Anchor technology’ working on anchors and soil behaviour for anchoring design.
Maximum loads have been estimated for two different sites, three floater concepts and several mooring configurations for a set of load cases, mainly maximum thrust and extreme environmental conditions. For each configuration the floater and mooring design used correspond to a preliminary design based on basic requirements given and will undergo optimisation in a later phase of TAILWIND project. Yet loads estimation at this stage provide useful inputs for already running WP2/WP3 activities.

The ambitious goal of the project is to introduce novel frameworks in line with the sustainable-by-design principle, which involves integrating economic, societal, and environmental considerations into design methods and technology selection processes. Deliverable 3.1 marks the first steps in the project, focusing on the identification of anchoring technologies for future development based on reference station-keeping systems. The anchoring system analysis comprises two key stages: Technical Reliability and Industrial Feasibility. In the Technical Reliability stage, the loads from the platform analyses are used to size state-of-the-art anchor types, including suction piles, driven piles, drag anchors, plate anchors, and gravity anchors. Industrial Feasibility involves the assessment of material sustainability, fabrication and transportation capacities, installation efficiency, decommissioning, and recyclability. The study results in the identification of promising anchor technologies for further development via experimental testing and numerical modelling within the TAILWIND project. The outcome amplifies the potential to unlock efficiencies and increase geotechnical reliability of infrastructure design.

Deliverable 1.2 and 5.1 cover technical, financial, social, and environmental KPIs, by providing a shortlist of such KPIs to be considered for sustainability impact assessment for the development of Floating Offshore Wind (FOW) renewable energy infrastructure.
