Description

A new type of floating breakwaters, mainly using the wave dissipation mechanism caused by wave slamming to a bundle of cylindrical members near the water surface, was developed. It aims attenuations of both reflected and trasmitted waves from the breakwater. Model tests show that the basic model of a floating breakwater consisting of a bundle of circular cylinders and rectangular floating units at both ends of the cylinders is not sufficient to reduce trasmitted waves. The improvements, such as additions of footing plates and vertical thin walls to the basic model, are very effective to reduce both reflected and transmitted waves.
