Impact pressures, due to slamming, are of particular importance in assessing local and global structural strength. Knowledge of pressure distribution and slamming forces, experimental or numerical, in the forefoot and aftbody of a ship can be used in the evaluation of global wave-induced loads, for example, whipping bending moment. Impact pressures and slamming forces for a bow section, impacting upright and at two angles of heel are presented in this article. The relevant impact loads are predicted using a range of two-dimensional potential and viscous flow methods and compared with available experimental measurements.

Abstract
Impact pressures, due to slamming, are of particular importance in assessing local and global structural strength. Knowledge of pressure distribution and slamming forces, experimental or numerical, in the forefoot and aftbody of a ship can be used in the evaluation of global wave-induced loads, for example, whipping bending moment. Impact pressures and slamming forces for a bow section, impacting upright and at two angles of heel are presented in this article. The relevant impact loads are predicted using a range of two-dimensional potential and viscous flow methods and compared with available experimental measurements.
