PREDICTION OF WAVE-INDUCED ROLLING RESPONSES BY A TIME-DOMAIN STRIP THEORY
This paper presents a time-domain strip theory formulation for predicting wave loads and 5-DOF motions of a ship at constant forward speed and arbitrary wave heading. The hydrodynamic memory effect due to the free surface is approximated by a set of higher-order ordinary differential equations, which can automatically include the non-linear memory effect and the momentum-slamming force. The formulation is generalized from the time-domain strip theory for vertical wave loads and ship responses. Based on time-domain strip theory formulation, a linear method for predicting wave-induced anti-symmetric motions and loads of rigid-body ships is developed. Numerical calculations are presented for a panamax container ship for the roll motion and torsional moment and are compared with experimental results.
