Abstract: The vast deepwater wind resource represents a potential to use floating offshore wind turbines (FOWTs) to power much of the world with renewable energy. However, the development of cost-effective FOWT systems poses many design challenges that must be solved with sophisticated computer-aided-engineering (CAE) tools. This lecture will summarize FOWT design challenges and the development, verification, and validation of CAE tools needed to address these challenges, with a special emphasis on the FAST CAE tool developed and supported by NREL. Understanding and addressing these FOWT design challenges requires CAE tools that model the physical phenomena and system couplings, including the environmental excitation (wind, waves, and current), and full-system dynamic response (rotor, gearbox and electrical drive, nacelle, support structure, and controller). NREL’s core CAE tool, FAST, joins rotor aerodynamics, substructure hydrodynamics, control and electrical system (servo) dynamics, and structural dynamics modules to enable coupled nonlinear aero-hydro-servo-elastic analysis of land-based and offshore wind turbine systems in the time domain. FAST is developed as a free, publicly available, open-source, professional-grade product as a resource for the wind industry.
Short Biography of Speaker: Dr. Jonkman joined NREL in 2000 and is the lead developer of the FAST and FAST-to-ADAMS preprocessor simulation software for modeling the dynamic response of land- and offshore-based wind turbines. He also provides technical support to designers, consultants, and researchers throughout the wind energy industry. He has performed studies to verify and validate the software, has published many papers on wind turbine dynamics, and has assisted in the certification of wind turbine design loads. Dr. Jonkman obtained his Ph.D. in aerospace engineering from the University of Colorado. Prior to joining NREL, he worked as a researcher at DOE's Industrial Assessment Center at Colorado State University and as a tool design engineer at the commercial airplane division of Boeing.
