Abstract

Bow-flare slamming has been paid attention in ship classification societies because it causes local damage or severe whipping vibrations which affects the ultimate strength and fatigue life of ship. WILS JIP-III (Wave Induced Loads on Ships Joint Industry Project-III) has been launched and conducted by KRISO, Korea, of which aims are to measure the slamming impact loads, vertical bending moment, and torsional moment in regular and irregular waves. A 10,000 TEU containership with six segments was used with the scale ratio of 1:60. The segments were connected by a U-shape steel backbone where a number of strain gauges were installed to measure structural responses. A number of force and pressure sensors were distributed on the bow-flare section in order to measure the temporal and spatial distribution of slamming load during tests. Based on the measured data, characteristics of the bow-flare slamming loads are presented and discussed.
