INFLUENCE OF BOTTOM AND FLARE SLAMMING ON STRUCTURAL RESPONSES

Real time computer experiments were performed that illustrated effects due to slamming. The phenomenon was investigated and the differing hull responses to 'bottom slamming' and 'flare slamming' were demonstrated. It was concluded that both impact and momentum forces should be included in the analysis and that previous predictions notwithstanding, the latter do not dominate; it is more accurate to suggest that they largely determine the time over which a hull is excited without greatly affecting the magnitudes of responses. To assess bow shape design, two hull forms were adopted. The first was a parent hull form with little or no bow flare above water and the second was a variant that had a very flared bow section but was identical to the parent form in every other respect. Both ships were run in similar seaways and real time simulations of the structural responses were evaluated. From the derived statistical data, the performance of these two ships is assessed and compared.
