NEW SLAMMING CRITERIA AND THEIR APPLICATION TO SHIP DESIGN

An investigation into some of the probabilistic aspects of slamming is presented. This includes an examination of whether slamming is a Poisson Process, an evaluation of the conditional probability of slamming at a given instant after a particular slam, and a presentation of procedures to extract the distribution of slamming interarrival times. In addition, new criteria useful for design purposes are introduced and the role that these criteria can play in the overall design process is discussed. The small angle criterion for slamming is discussed and a sensitivity analysis with respect to all important slamming parameters is presented. The sensitivity of the results with respect to the truncating frequency is also studied. The work puts strong emphasis into the assumptions used in slamming statistical theory and suggests directions for subsequent extensions and improvements.
