Liquid Sloshing in Cargo Tanks

Abstract

Based upon a survey of 12 cases of sloshing damage on 7 tankers and other ships of dry cargo, OBO, bulk and ore carrier types, 5 structural members were chosen for model testing to measure sloshing forces. Oscillating table tests were then run using partially filled tanks with realistic structure including the instrumented members. Sloshing force and moment coefficients are reported as well as sloshing pressure coefficients from pressure measurements on the tanks. A linear superposition calculation for sloshing force on one member is shown. Keywords: Sloshing; Sloshing forces; Impact pressures; Oscillating table; Ships; Sloshing damage; Response amplitude operator; Seaway spectrum.
