A simplified model and procedure is employed to estimate hydrodynamic forces on a bow with large flare, and the resulting vertical bending moment along a ship hull. The dynamic amplification due to hull flexibility is considered and the effect appears to be significant for loads with the predicted magnitude and duration (1.2-2 sec.). It is suggested that the short term distribution of loads and stresses due to bow flare impact can be described by Weibull probability distributions. The influence of ship speed and sea state on the loads and responses are investigated to some extent, and it is concluded that the influence of ship speed is relatively much stronger at severe sea states.
