Abstract
Mainly, Floating Breakwaters(FBs) have been constructed in many coastal regions due to the advantages of the coastal environment and construction cost. In general, the FB becomes fixed or its width broadened because the movement of the FB comes to be large and its the wave control function lower for the long period incident waves.


In this study, efficiency of the FB is evaluated for various mooring systems using Eigenfunction Expansion Method(EEM) in two-dimensional wave field. And, the wave control function of two-rowed Fixed Floating Breakwaters(FFBs) that have narrower width than that of the one-rowed FFB is discussed by using Boundary Element Method(BEM) based on the Green formula and EEM. The validity of the present study is confirmed by comparing it with the results of Ijima et al.(1974) and Yosida et al.(1992) for the one-rowed Fixed Floating Structure. Of mooring forms, Open Catenary Mooring is the best one about the transmission ratio, sway, heave, roll motion, and mooring line force. It is revealed that the wave control function of two-rowed FFBs is more effective than that of the one-rowed FFB.
