The forces and overturning moments exerted by waves on a rigid vertical circular cylinder extending from the bottom through the water surface, have been measured for a range of wave conditions. The tests were on a cylinder 30.5 cm in diameter, in varying water depths. A digital computer was used for acquisition, processing, plotting, and storage of the experimental data. The results of the tests were compared to the diffraction theory of R.C. MacCamy and R.A. Fuchs (1974) and showed that the theory is suitable for use over a wide range of conditions. The diffraction theory was used to derive equations from which design curves were plotted. The curves provide a simple method of determining wave forces and overturning moments on large diameter cylinders.
