Concept development and optimization
Upscale innovative floating substructure concepts to a 10 MW wind turbine for water depths greater than 50 meters. During the process several reports regarding oceanographic and meteorological conditions for the design, wind turbine models for the design, concept design, wind turbine controller adapted to each concept, report on marine operations, up-scaling procedures, information for concepts evaluation and concept design optimization will be produced.

- Deliverable 1.2 Wind turbine models for the design (Summary)
- Deliverable 1.6 Upscaling procedures (Summary)
Under this framework all floater concepts will be analyzed at different stages of the design development in the previous work package, and the results will provide important inputs to the designers. The evaluation will be carried out for the three sites selected in Deliverable 1.1 and for different offshore wind farm sizes (e.g 1, 5, 50 turbines). The evaluation includes report on evaluation procedures and tools, the evaluation tools themselves (software), and reports describing the performance of the concepts.

- Deliverable 2.9 Presentation of the methodology and results of the WP at a relevant conference (Summary)
This work package verifies the feasibility, safety, and performance of two selected substructures out of the four designed in the first work package. The reliability of existing techniques for floating offshore wind turbines will be increased. During the experiments the numerical models will be calibrated. Moreover, this work package works out how wind tunnel and ocean basin tests can be combined in an optimal way to validate substructure concepts efficiently and more accurately than today.

Qualification of numerical tools
The work package focuses on the qualification of numerical models and their rational use in design optimization and design verification. A multi-fidelity approach is utilized, centered around state-of-the-art aero-elastic modelling which is nowadays used for design verification; simpler, efficient models which are turned into an optimizing pre-design tool, and advanced models at component level that predict physical load effects associated with large floaters beyond state-of-the-art. Schematically, these three levels of models are placed along the diagonal in the accuracy-CPU time diagram and the work package focuses on the increased efficiency of and accuracy potential associated with the combination and validation at models at all levels.

The general scope of this work package is a Floating Offshore Wind Turbine (FOWT) system industrialization where existing validated numerical tools enhanced by developments from the previous work package are adopted to perform an industry evaluation and manufacturability study of the two selected TLR4 substructures and TLR5 qualify these concepts for large wind turbines and large water depths. The delivery of this work package is an industry-focused methodology for cost-effective designs of the entire FOWT system, which is consequently applied to the two FOWT concepts and result in optimized designs with low LCOE.

Uncertainty and risk management
Uncertainty and risk in design of floating substructures can be critical to understanding potential operational capabilities and validation of new designs. This WP will focus on the development of a methodology for risk management specifically designed for offshore wind substructures; the methodology will be applied to evaluate the risks associated to the new substructures being developed in the context of the project. The WP coordinator will ensure that all relevant risks are considered in an appropriate way and correctly evaluated by competent project partners. The risk assessment methodology will be formulated taking into account the contributions and the perspectives of the key stakeholders participating in the project: designers, OEMs, developers/operators, and testing centers.
- Deliverable 6.1 Risk Management for Deep Water Substructures (Summary)
- Deliverable 6.6 Publication and presentation of the research performed in the WP (Summary)
This work package will scrutinize, examine and summarize the process and activities of all work packages related to design questions throughout the entire project to develop a recommended (industry-) design practice (RDP) for the design and qualification of large FOWT substructures to support the innovative process of the technology by creating a document to guide the reader through the design. In order to fulfill that objective, initially a review of existing design practice and guidelines for floating offshore wind turbine substructures will be performed. Additionally, relevant information, lessons learned, key findings and new knowledge generated within all design related work packages will be continuously analyzed at important milestones of the other work packages.
