| Research Abstract |
We proposed a fin-attached structure to reduce motion and wave drift of a float structure installed on the sea. As the 1st step, the characteristics of hydrodynamic force acts on a oscillating fin under a free surface is measured. We propose a new method to decompose the hydrodynamic force into added mass, damping and viscous force. The wave making damping term was added to a conventional Morrison formula. The effect of the period and amplitude of motion are investigated
