Sph Modeling Of Extreme Wave Overtopping On A Fixed Deck

Abstract

Highly nonlinear problem of extreme wave overtopping on a horizontally fixed deck plate is modeled using Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) method. Wave overtopping on the lower decks of offshore platforms and on the decks of ships cause significant structural damage and increase safety risks due to the tremendous momentum generated by the wave overtopping. Two cases of SPH simulation are run with and without the deck using the same extreme wave condition to quantify the effect of deck structure on wave characteristics. The numerical study showed that the deck plate increases free surface elevation at the leading edge of the crest by 16%. The experimental results are used to validate the numerical model developed.
