On The Statistical Properties Of Wave Force

Due to fluctuation of the free surface, points on the cylinder may rise above or fall below the water surface. At instants when the point is not submerged, it experiences no wave force. This is recognized, in the case of single wave (Ippen, 1966). For random waves, however, such consideration has so far been ignored (Borgman, 1971). It is the purpose of this paper to derive expressions for some statistical quantities of wave field kinematics and wave forces on elements of a vertical cylinder in a random wave field with due regard to the phenomenon mentioned above and to examine its effects on these quantities.
