Experimental investigation of moored-buoys using advanced video techniques

Abstract

Physical model tests were conducted to validate numerical models of moored-buoy systems. Three buoy types (sphere, spar and discus) were tested for intrinsic properties, three-dimensional impulse response and three-dimensional dynamic response to two-dimensional regular and random wave excitation. Buoy kinematics were measured using advanced video imaging techniques. Other data collected included upper and lower mooring line tension and mooring line inclination. Physical model development, test and measurement procedures and data collected are discussed.
