Abstract
The report describes a theoretical and an experimental investigation into the vibration of three ring-stiffened circular cylinders under uniform external water pressure.

The theoretical investigation for both the structure and the water was with the aid of the finite element method. Comparisons between experiment and theory were good and the investigation found that as the external water pressure was increased the resonant frequencies decreased, and also that the lowest mode of vibration became of a similar form to the static buckling eigenmode.
