A common problem in a marine environment is associated with the interaction of a vibrating structure with the surrounding fluid. A variety of analytical and numerical solutions have been proposed for this situation often employing approximations as analytical solutions only exist for very straightforward geometrics. However, very little experimental data are available for comparison in this field. The paper describes a series of dynamic studies conducted upon a cylindrical structure tested in air and totally immersed in water. Modal analysis techniques have been used to identify the natural frequencies and mode shapes under both conditions. Good correlation has been obtained between experimental results and an analytical model.
