Physical model tests were conducted to validate numerical models of mo
ored-buoy systems. Three buoy types (sphere, spar and discus) were tes
ted for intrinsic properties, three-dimensional impulse response and t
hree-dimensional dynamic response to two-dimensional regular and rando
m wave excitation. Buoy kinematics were measured using advanced video
imaging techniques. Other data collected included upper and lower moor
ing line tension and mooring line inclination. Physical model developm
ent, test and measurement procedures and data collected are discussed.
