THREE-DIMENSIONAL STOCHASTIC RESPONSE OF OFFSHORE TOWERS TO WAVE ACTION

A theory is developed to calculate the dynamic response of offshore towers to random wave forces. Vibrations are considered simultaneously for translations in the orthogonal horizontal directions and for rotations about a vertical axis. The idealized structure for the dynamic analysis has its masses lumped at discrete horizontal levels. The ocean waves are considered to be a zero mean stationary ergodic Guassian random process described by the directional wave spectrum, which specifies the distribution of wave energy with respect to frequency and direction.
