Characteristics of bow-flare slamming loads on an ultra-large containership in irregular waves

Abstract

Bow-flare slamming has been attracting major ship classification societies because it causes local damage and severe whipping vibration that affect the ultimate strength and fatigue life of ships. In the present study, a series of experimental investigations has been made on bow flare slamming loads under irregular wave conditions, which was a part of WILS JIP-III (Wave Induced Load on Ships Joint Industry Project-III). A 10,000 TEU containership model with six segments was used and a number of load cells were distributed on the bow-flare and deck areas in order to capture temporal and spatial distributions of slamming load. Based on the measured data, characteristics of the bow-flare slamming loads in irregular waves are presented and discussed.
