FOURIER-KOCHIN FORMULATION OF WAVE DIFFRACTION-RADIATION BY SHIPS OR OFFSHORE STRUCTURES

An analysis of ship wave diffraction-radiation based on a Green function satisfying the linearized free-surface boundary condition and the Fourier-Kochin approach is developed. Free-surface effects are represented by a double Fourier integral involving spectrum functions defined by distributions of the elementary wave function over the hull and the waterline of the ship. Two basic mathematical representations, called the potential representation and the velocity representation, of the spectrum function associated with the kernel of the integral equation are given and evaluated. The velocity representation is found to provide a substantially more solid mathematical basis for the purpose of numerically evaluating influence coefficients.
