Abstract
Freak waves are large and unexpected surface waves with huge wave heights that can lead to severe slamming to ships and marine structures. However, there are only few researches conducted to investigate the wave impact on the deck-house caused by freak waves. In order to understand the phenomena and be able to calculate the structural response of the deck-house structures, a 2-D numerical wave flume is built in which freak waves are generated. A simplified method is proposed to approximate the deck-house wall as an Euler beam with intermediate elastic bearings. By applying an implicit iterative algorithm, the fluid-structure interaction (FSI) is considered. Three simulations are performed, including a regular wave impact against a rigid wall, a laboratory-scale freak wave impact against an elastic wall, and the deck-house impact caused by a full-scale freak wave. Visual snapshots are taken to show the entire wave slamming phenomena. Fluid pressures adjacent to the wall are reported to indicate the influence of hydroelasticity. The displacements of the vertical wall and the deck-house wall from a semi-submersible barge are analyzed with the fast Fourier transformation (FFT) and wavelet transformation method.
