... to predict efficiently the probability of deck-slamming occurence for offshore structures. The present approach is based on the assumption of potential flow up to the second order and has four steps: representing relative wave elevation as two-term Volterra series, solving the eigenvalue problem, formulating...

Paper Number: OTC-26498-MS
... Abstract In this study, advanced numerical CFD tools based on OpenFOAM are developed to generate extreme waves for the investigation of wave-in-deck loads on fixed offshore structures. The numerical method employs a Navier-Stokes solver with the free-surface captured by the volume of fluid (VOF...

... of an offshore structure. In this work, we proposed a hybrid numerical scour model which estimates the equilibrium scour depth around a structure by utilizing hydrodynamic turbulence models to obtain key flow parameters and an optimization function to predict the equilibrium scour depth. It was demonstrated...
