WAVE FORCES ON SUBMERGED CYLINDERS
This paper describes a simple method to calculate wave forces on a submerged large, vertical cylinder of arbitrary height standing on the sea floor. The method is based on a long wave solution of the wave scattering problem valid for wavelengths comparable with the cylinder diameter. This long wave solution, however, converges towards exact solutions when the cylinder top is either approaching the sea surface or the sea bottom. From the formulae obtained, a set of still simpler asymptotic expressions for the forces due to very long waves are deduced. The very long wave expression for the horizontal force is compared with the Morison's equation, and an expression for the mass coefficient valid for submerged cylinders is suggested. Based on a comparison of results obtained by the present theory and results from model measurements and alternative computations, the author has found the agreement to be significant.
