PREDICTION OF MOTIONS OF OCEAN PLATFORMS IN OBLIQUE SEAS
This report presents a new procedure for predicting the motions of some ocean platforms in oblique waves. Frank's method of calculating hydrodynamic forces and moments on oscillating cylinders is extended not only to the calculation of hydrodynamic moment arms but also to the calculation of wave-exciting forces and moments on a restrained ocean platform in oblique waves. The coupled vertical and lateral equations of motion are applied in determining the important motions of ocean-platform models of the ship and jackup type, in oblique seas. The predictions are in good agreement with the experimental results. (Author)
