Vortex-induced vibration effect of extreme sea states over the structural dynamics of a scaled monopile offshore wind turbine

Abstract In order to demonstrate the relevance of considering Vortex-Induced Vibrations (VIV) in structural design marine structures, this study proposes an alternative experimental and analytical approach wet conditions measure fluid–structure interaction near field quantify viscous damping with measured 3D hydrodynamic accelerations. It was demonstrated that VIV caused incremented 5.00% coefficient, extreme wind loading increased 74% offshore monopile’s damping, demonstrating high non-linear hydrodynamics effects during selecting parameters into applications.
