The forces and overturning moments exerted by waves on large vertical circular cylinders have been measured in the laboratory. Two rigid cylinders, 12 in. and 26.5 in. in diameter, extending from the bottom of a wave flume through the water surface, were tested in varying depths of water, for a range of wave periods and wave heights up to the point of breaking. A digital computer was used for the acquisition, processing, plotting and storage of the experimental data. In addition to the experimental work, a design method is presented which allows the wave loads on large circular cylinders to be estimated by means of a simple desk calculation. The experimental data shows that this simple method of calculation, based on the linear diffraction theory of MacCamy and Fuchs, is accurate over a wide range of wave conditions and cylinder sizes.
