Potential-based boundary element method to calculate the hydrodynamic drift force on the floating cylinder

Abstract

This paper presents the calculation of the hydrodynamic drift force by using the potetial-based boundary element method (BEM). The potential theory and far-field wave drift forces solution will be described. The comparison of non-dimensional drift force for surge and heave motions are in good agreement between numerical and experimental data. The effect of different drafts and the radius of a cylinder on the drift forces (surge, heave and pitch) are presented and discussed. MSC 2010: 31B25, 76B15, 76B07
