Characteristics of Stern Slamming Loads on an Ultra-large Containership in Regular and Irregular Waves

Abstract

Stern slamming is one of important issues in a design of ultra-large containership. In the WILS JIP-III (Wave Induced Load on Ships Joint Industry Project-III), stern slamming loads on a 10,000TEU containership were measured in order to see characteristics of stern slamming load. The ship model has six segments connected by a steel backbone and the scale is 1:60. For the measurement of stern slamming load, 5 load cells were distributed on the stern area. The stern slamming impact were measured towing the ship model in regular and irregular waves. Head and following sea conditions with different ship speeds were applied. Based on the measured data, characteristics of the stern slamming loads are presented and discussed in the present study. characteristics of stern slamming load.
