The effectiveness of floating breakwaters in reducing waves can be achieved by adjusting the placement of structures according to conditions in the field. The effect of floating breakwater layout will affect the transmission and reflection waves. This study numerically modeled a floating breakwater with 0° porosity using Flow-3D to determine the reflection and transmission waves. The layout under study is a connection of three single-model floating breakwaters (I-shaped), connected by connectors made of coated wire rope in three variations of placement for wave incident angles (0°, 30°, and 60°). The study results show that the greater the angle of inclination of the structure causes an increase in the transmission coefficient and the lower the reflection coefficient. Floating breakwater layouts with tilt angles of 0°, 30°, and 60° have transmission coefficient values that differ not too significantly, where the tilt angle of 60° is more effective at damping waves compared to other tilt angles.
