MAIN OBJECTIVES
15
• Design a 5MW WTG from conceptual to detail-constructive engineering.
• Study the concept scalability for a 12 MW WTG.
• Build a fully coupled aero-hydro-servo-elastic Floating Wind Turbine
model and investigate coupling effects in the overall wind turbine
performance
• Model Basin Tests in operating, extreme and installation conditions
• Perform laboratory tests to study the performance of the suspension
tendons
• CapEx and OpEx estimate. Viability analysis of a single installation and
integration in a multi-megawatt floating wind farm
• Obtain the Certification of the design
• Project dissemination in general and technical forums and conferences
