PREDICTION OF DRIFTING FORCE AND MOMENT ON AN OCEAN PLATFORM FLOATING IN OBLIQUE WAVES

The paper presents a new procedure for predicting the lateral drifting force and moment on an ocean platform floating in oblique waves. The disturbance of an incident wave caused by the presence of the floating body is represented by the sum of the diffracted and forced wave potentials, which are determined by satisfying the kinematical boundary conditions on the body surface. The scattered waves are determined from the asymptotic expression of the two potentials. Frank's close-fit method, Grim's strip method and Maruo's formula for two-dimensional drifting force are used. Numerical results were compared with experimental results and found to be in good agreement. (Author)
