This paper deals with two calculation methods, using Rayleigh-Ritz method, of natural frequencies of vibrating circular cylinder submerged horizontally or vertically in water. These methods were presented previously by the author, of which one was the hydroelasticity method and the other the approximate method. The former was very effective for the analysis of flexural vibration of circular cylinder in water and the latter for the analysis of ship vibration. In this paper, natural frequencies of circular cylinder computed by the approximate method are shown to be comparatively in good agreement with those computed by the hydroelasticity method.
