Concept development and optimization
• MS#1 completed defining the conditions for the concepts design –locations, met-ocean conditions and wind turbine model
Concept evaluation
• LIFES50+ Overall Evaluation tool named “Floating Offshore Wind Assessment Tool- FOWAT” have been developed (MS#3) in order to qualify the four concepts designs under an economic, environmental, risk and technical perspective, which enabled the calculation of the following aspects to be considered in Phase I (MS#4) and II (MS#5) evaluation of the concept designs.
Experimental studies
• A 10MW Wind Tunnel Model (PoliMi 10MW WTM), the Olav Olsen OO-Star and NAUTILUS concepts have been designed,built and tested in SINTEF's Ocean Basin and in POLIMI's wind tunnel.
Qualification of numerical Tools
• Created an overview of the numerical models, which contains an overview of the design tools applied for floater design, and the models used by the consortium partners and their qualifications.
• Two simplified numerical models for up-scaled design have been set up for a generic floater concept and the 10MW turbine: The SLOW (Simplified Low-Order Wind turbine) model of USTUTT and the QuLA (Quick Load Analyses) model at DTU.
The public floater designs were defined, implemented and shared as public FAST models. The mod-els were next validated against the physical model tests and the accuracy was further compared to the simplified QuLAF and SLOW models. Advanced models were developed for modal damping; damp-ing detection with Operational Modal Analysis; CFD calculation of floater forcing and response; second order forcing of low-frequency response; aerodynamic rotor loads through a free vortex model and inclusion of floater flexibility into the dynamic floater-turbine response. The advanced models were validated against physical model tests. Finally, the state-of-the-art model concept was tested against data for a full-scale floating platform.
Concept industrialization
• A methodology was demonstrated showcasing the transition from conceptual to detailed design considering the aspects of commercialization and recommendations for design of internal structures including reviewing the fabrication and installation processes of the FOWTS, completing the technology risk assessment, and providing guidance on platform and mooring line selection, installation and marine operation
Uncertainty and risk management
• Establish a methodology showing how risks associated with deep water floating substructures could be identified, evaluated, treated and the uncertainty and risk management framework.
Design practice
• A review of available certification guidelines and recommended practices has been carried out and an overall understanding of the individual topics considered in the certification process of a FOWT have been established (MS#6).
• A set of design load cases and environmental conditions have been defined, and the design requirements have been identified for the FOWT design (MS#7).
• A high-level overview of the SoA design practice of 10 MW floating wind turbine substructures and the relevant guidelines have been created (MS#8)
Dissemination and exploitation
• Project external website established. Press release and short newsletters with updates on the project developments and summary versions of the public deliverables.
• Promotional material produced including a project logo and flyer.
• More than 80 presentations, poster and papers at highly respected conferences.
• 8 scientific articles have been published in relevant journals
• During the course of the project 32 IP-I (Innovation Potential-inventory), 1 PPI-d (Possible Protectible IP-declaration) and 1 Patent application have been generated.
Management and technical coordination
• Creating and distributing required procedures related to the day to day running of the LIFES50+ project, hereunder the handbook for management procedures, project quality and risk management plan as well as the IPR guidelines
