Abstract

The second-order wave loads are computed for the diffraction of monochromatic waves by a surface-piercing vertical cylinder in the finite and infinite fluid depths. The Weber transform method which is essentially a Hankel transform method with a more general kernel, is applied to compute the second-order force due to the second-order velocity potential. Suitable closed contours in the complex plane are used to derive the analytical solution of the improper integrals involved in this study. This makes the present solution distinct from the other available solution of the second-order forces.
