Abstract
In order to investigate the increased damping of a moored semisubmersible during low-frequency motions in waves, free oscillation tests were conducted both in still water and regular waves. Test results show the influence of both wave and viscous forces on the low-frequency damping, and it seems that the interaction effects among columns play an important role in the increased damping due to wave effects in short waves. Calculations and experiments in regular wave groups were also compared to investigate the effect of increased damping due to waves on the low-frequency motions.
