“…The DCFB system is less intrusive in the shoreline environment as compared to conventional breakwaters and does not cause significant modification on the natural system [17]. It also has the ability to adapt to different wave conditions and can be designed to meet specific application needs, such as offshore renewable energy generation, infrastructure preservation, recreation, temporary structure, and create controlled environment for various aquaculture activities [18][19][20][21][22][23][24][25][26][27][28][29]. This study investigates the wave transmission coefficients of TCFB with different sizes and arrangements.…”

Floating breakwater is a better alternative than the conventional method. It is an effective coastal engineering unit used to protect coastal regions such as harbours and marinas from erosive waves. It has many other applications such as offshore renewable energy generation, infrastructure preservation, temporary structure, and provides a controlled environment for aquaculture activities. The floating breakwater such as the double cylindrical floating breakwater (DCFB) is claimed to have effective wave attenuation characteristics. A lab scale investigation was done by placing the DCFB in a controlled wave basin in with wave generator to generate wave and wave gauge to quantify the wave transmission coefficient. The wave transmission coefficient represents the effectiveness of the breakwater system in attenuating incoming waves, where an effective breakwater system will result in a low transmission coefficient value. In this study, the DCFB’s effectiveness in terms of wave transmission coefficient was investigated with two different configurations where the spacing between the cylinders of the DCFB units are 0.2 m and 0.6 m respectively. Results show that the configuration of DCFB units with 0.5 m cylinder spacing are more effective in absorbing incoming wave height resulting in lower transmission coefficient. Furthermore, some prospective areas had been identified for future enhancement.
