A series of model tests in a regular wave tank have been conducted to validate the theoretical solutions for the first order and mean drift responses of an articulated column, which have been developed in the first report. Measured results for the first order wave-induced hydrodynamic forces and tilt response as well as for the mean drift overturning moment on a model column are presented in this second report, and compared with theoretical predictions based on the potential flow theory. Agreement between the experimental data and the theoretical predictions is found to be satisfactory over a range of frequencies if the effects due to reflections from the tank side walls are taken into account in the theory. These results seem to suggest the validity of the potential flow theory for estimating the first order and mean drift responses of the articulated column in open sea.
