This project, funded by the U.S. Department of Energy (DOE), will upgrade the soil-foundation interaction (SFI) testing facility by acquiring new capabilities and to develop a coupled aero-hydro-mechanical hybrid simulation approach to accurately model U.S. field conditions in the laboratory and simulate current and next-generation fixed-bottom and floating offshore wind turbines (OWTs). The new testing capabilities and hybrid simulation approach will be used to perform pilot projects simulating U.S.-specific environments. These efforts will be accompanied by a marketing campaign to broaden the user base of the facility and develop collaborative projects.
