MOTIONS OF LARGE STRUCTURES IN WAVES AT ZERO FROUDE NUMBER

In this paper a three-dimensional source technique has been applied to a floating object in regular waves and the added mass and damping coefficients, the wave exciting force and moment and the motions in six degrees of freedom and the pressure distribution have been calculated. The horizontal drift force and moment have also been evaluated. Numerical calculations and experimental results for the case of a floating box of dimensions 90 m x 90 m and a draft of 20 m and 40 m show very good agreement in the measured quantities. On the basis of this comparison one may conclude that the method does indeed provide a solution to the dynamic analysis of large three-dimensional structures in waves, subject, of course, to the usual limitations of the linearized theory.
