Characteristics of Bow-flare Slamming Loads on an Ultra-large Containership in Irregular Waves

Abstract

Bow-flare slamming has been interested in many ship classification societies as it can cause local damage or severe whipping vibration that can affect the ultimate strength and fatigue life of ship. In the present study, an experimental investigations are made on bow slamming loads under irregular wave conditions, which are a part of WILS JIP-III (Wave Induced Load on Ships Joint Industry Project-III). A 10,000 TEU containership with six segments was used and many load cells were distributed on the bow-flare and deck area in order to measure the temporal and spatial distribution of slamming load. 3hour simulations were carried out for different wave heading angles and ship speeds. Based on the measured data, characteristics of the bow-flare slamming loads in irregular waves are presented and discussed.estigations are made on bow slamming loads under irregular wave conditions, which are a part of WILS JIP-III (Wave Induced Load on Ships Joint Industry Project-III).
