Abstract

Eigenfunction expantion method is applied to the radiation problem on water of finite depth. In this paper, vertical oscillations of the floating body are considerd. Numerical calculations were made for three types of body shape such as a half immersed circular, a Lewis form and a rectangular cylinder. The results for a circular and a Lewis form cylinder show relatively good agreement compared with other methods. On the other hand, in case of rectangular cylinder the correspondence is not satisfactory and further investigations are needed.
