Abstract

Wave attenuation performance of Improved Wave Suppress System (IWSS); a floating breakwater system used to dissipate wave energy, has been studied in this project. For the first semester, IWSS has been designed and developed to enhance wave attenuation performance of the existing Wave Suppress System (WSS). Experimental studies have been carried out for the calibration of wave period, and determination of attenuation performance of WSS and IWSS in terms of reflection coefficient, Cr, transmission coefficient, Ct, and loss coefficient, Q in various water depths and stroke adjustments. From the experimental result and analysis, it is found that WSS is not a good reflector but indeed a good dissipator, as it is capable in attenuating up to 96% of wave energy. The results also show that IWSS models produced lower Ct values compared to WSS. The addition of keel plate underneath IWSS has increased the draft of the structure, thus enhanced the attenuation performance of the breakwater. It can be concluded that IWSS with keel plate is a good reflector as it has improved the wave reflection ability. WSS and IWSS models performed very well in 20 cm water depth and short wave period. Comparison ofWSS and IWSS models with previous studies indicates that draft and width has significant effect on the performance of floating breakwater.
