A study has been made of slam-induced midship hull stresses on a general cargo ship in North Atlantic service. The slam-induced stresses superimposed on wave stresses were treated statistically for different Beaufort numbers in the range of 4-10. It was found that although the percentage of records with slamming increases with Beaufort number, the overall frequency of slamming first increases and then decreases with Beaufort number. This is because the higher Beaufort numbers occur less often than lower numbers. As for the magnitude of slamming stresses, it was found that the statistics are relatively insensitive to Beaufort number and hence to sea condition. It is shown that this finding is accounted for by the reduction in speed and/or change of course that is normally adopted by the master as weather becomes more severe.
