The features of a mobile breakwater concept based upon a perforated front wall and solid back wall are presented. The principles of energy dissipation by the system is discussed as well as the potential role of such a device within the framework of practical application. Model test results, comparing the perforated breakwater's response to waves with that of a caisson-type breakwater, are discussed. The author shows that the perforated breakwater experiences less force on the structure when it is fixed to the bottom and less force on the mooring lines when afloat than the caisson-type. However, the perforated breakwater is not more effective in reducing waves, for the conditions tested. Observations disclosed that scouring is prevalent when the caisson-type is fixed to the bottom whereas there was no evidence of scouring with the perforated breakwater. Recommendations for further work include optimization of the breakwater design and testing in a three dimensional wave tank under a large range of wave conditions.
