Abstract

Waves and winds that move dynamically often cause damage on the coast so a protective beach building is needed. Breakwater is a coastal protection structure to destroy the incoming wave energy before reaching the coast. One type of breakwater is floating breakwater, this structure has an advantage compared to the fixed breakwater. Research on floating breakwater has been developed with the main goal of being the most efficient structure and can absorb waves well. In this research, floating breakwater simulation modeling with variations in bilge keel length was conducted. Validation is done by comparing the results of (GH Dong, 2008) with numerical results of the breakwater pontoon type. There are four variations of bilge keel length, namely 0 m, 0.6 m, 0.9 m, and 1.2 m. So, four variations can be concluded that the longer the bilge keel, the better absorb the waves.
