EXPERIMENTAL STUDY ON WAVE HEIGHT REDUCTION EFFECT AND DYNAMIC BEHAVIOR OF TEMPORARY FLOATING BREAKWATER

Abstract

 A temporary floating breakwater has been proposed to keep calm wave conditions in an offshore construction site. In this study, its transmission coefficient and dynamic behavior were investigated from hydraulic experiments. Experimental results showed that the transmission coefficient decreased with an increase in the wave steepness and relative breakwater width. Furthermore, the time from the peak of the heave to that of the sway increased with the relative breakwater width and the temporal changes in the heave and sway had a nearly opposite phase for large relative breakwater widths, resulting in the abovementioned decrease in the transmission coefficient.
