Abstract

The hydrodynamic forces and motions of floating cylinders with arbitrary cross section subjected to beam waves are studied in the time domain. The hydrodynamic radiation forces are represented by infinite frequency added masses and convolution integrals of memory functions. The exciting forces are calculated in the frequency domain. The hydrostatic forces are evaluated both around the mean equilibrium position and over the instantaneous wetted surface in order to assess the effect of the non-linearity of these forces. Results of sway, heave and roll motions are presented for cylinders with rectangular and triangular cross section shap
