Project objective

To improve the way effects of steep (and breaking) waves are taken into account in the design methodology of fixed offshore wind turbines, so that optimized offshore wind turbines can be developed.

Expected outcome

The output of the ‘WIFI’ JIP will be a methodology to take extreme waves and non-linear wave effects into account in the design of offshore wind turbine construction. The experimental and validated design method will be used by participants to have a better quality control on the design of their constructions. The project will give new and indispensable results on maximum response as well as fatigue loading of the construction. • Model test, CFD calculation and full scale measurement reports, containing the measurement and calculation results, discussion and validation analysis of the results. • Design method: “Best practice” reference document, with case study results describing the step-by-step analysis and design approach, upon which formal guidelines can be based. Finally the above mentioned deliverables will be used to improve the classification guidelines and requirements of DNV and GL.
