A Design Tool for High Speed Ferries Washes
The high waves generated by fast ferries may have detrimental effects when approaching the coast. The aim of this study is to determine the characteristics of ship wash or groups of high-speed ship waves in coastal and shallow water regions. The purpose of the method developed herein is to provide a tool for authorities as regards speed limits and routes for fast ferries approaching the coasts. The waves generated by high-speed ships are represented by their free wave spectrum. This spectrum is determined digitally using a wave resistance program (POTFLO) based on the Neumann Kelvin model. It is assumed that the free waves propagate in the same manner as a short crested sea, defined by a directional energy spectrum. This energy spectrum is expressed explicitly in terms of the free wave spectrum. Spatial wave propagation is then modeled over time using a third-generation spectral wave model named TOMAWAC, based on a finite element technique. Evolution over time is depicted at certain critical positions along the shore. Results are given in terms of significant wave heights and mean wave periods for different ship routes and speeds.
