Abstract

Ocean wave excitation contributes to the emergence of noise in the communication system that is applied to the ocean. This paper delivers the preliminary design of the smart buoy with noise reduction capability provided by the attached dynamic vibration absorber (DVA) automation system. Hydrostatic stability and hydrodynamic characteristic of the designed buoy structure are two main objectives in this study by generating numerical calculations using ANSYS AQWA in the irregular wave condition and variations in mooring line types. Finding result shows that the designed buoy structure is in stable equilibrium with a metacentric height of 0.456 m and has the highest amplitude response of 0.4 Hz for 6 DoF (Degrees of Freedom) of the buoy motion. The four-lines catenary mooring has delivered a good performance in the hydrodynamic time response analysis compared to the single-taut and single-line catenary moorings by producing the smallest buoy displacement with a maximum surge of 3.354 m, sway 0.287 m, heave 1.874 m, roll 22.818°, pitch 24.427°, and yaw 54.542°, and smallest cable tension with a maximum value of 32.175 kN. This study can be used to develop a DVA automation system and be extended by experimental validation.
