Abstract

A unified method of computing wave loads acting on a ship in head irregular seas is proposed. The linear portion of hydrodynamic loads produced by the method is equivalent to the loads as evaluated by the classical linear seakeeping strip theory. The nonlinear terms represent primarily the impact loads called slamming. In deriving the mathematical model for the slamming loads an equivalence of two suppositively different methods, impact and momentum theories, is shown. Results of computations in terms of time-histories of accelerations and structural stresses are presented together with the corresponding full-scale experimental values. Computed slamming pressures are compared to the values measured in model and full-scale cases.
