Abstract

In recent years, series of studies has been conducted to evaluate the wave attenuation ability of a floating breakwater model namely the Wave Suppress System (WSS). Aprototype model was designed to provide a shape which could effectively attenuate waves with the aim of determining the ability of the structure in various conditions. An experimental project on the wave attenuation ability of a floating breakwater was carried out as a final yearprojectto further improve the performance of the WSS. The aim of this study is to evaluating the performance of three floating breakwater models in terms of transmission which was done experimentally and analysed in detail and in terms of reflection and energy loss which were made through observations during the sessions of experiments. Besides that, discussions were made to determine the factors that affect the attenuation ability of the floating breakwater models. Twelve sets of experiments were conducted and several literatures on previous tests done on floating breakwater have been reviewed throughout the study. With reference to the original design of the WSS floating breakwater, three floating breakwater models was fabricated for the study - Ml, M2, and M3 which were all made of wood assembled into a hollow box with a basic shape of30 cm long, 20 cm wide and 10 cm tall. All models are proven theoretically and experimentally stable having a draft of 6 cm for Ml, 6.9 cm for M2, 4.9 cm for M3. Laboratory experiments were conducted to evaluate the performance of allthree floating breakwater models. The results were presented and analysed clearly in this report. It was found that the performance of all three floating breakwater models were more effective when fixed by piling systems. The CT values for Ml, M2 and M3 were smaller when anchored by pile system compared to cable. The wave attenuation ability of all floating breakwater models were more effective in water depth of 20 cm for pile system while for cable system, the models were more effective in water depths of 30 cm. In conclusion, M2performs best for pile category while M3 attenuates more wave energy for cable system category.
