Performance of a New Floating Breakwater

Abstract

The need of floating breakwater is increased to protect harbour by wave storm. The study and development of some model have been done in the past decade. However, their model still not effective to protect harbour against wave period greater than 5.0 second. This study deals with performance of a new type floating breakwaters in terms of heaving motion and transmission coefficient. The result compare with heaving motion of PI-type floating breakwater. Heaving motion is evaluated by using seakeeper tools, while transmission coefficient is obtained through laboratory experiment. The results indicate that the performance of proposed model better than PI-type model in terms of motion and transmission coefficient.
