If you have a question about this talk, please contact Magdalena Charytoniuk.

The talk will provide a brief introduction to the issue of liquefaction of cargo in ships and explain the recent interest in the topic, the types of cargoes that are problematic and the procedures used to ensure safe transport. Although the cargoes are nominally dry, in practice because of mining and processing procedures the ores often contain significant amounts of moisture when placed into ships. The results of several series of tests conducted to understand the unsaturated soil mechanics behind the liquefaction phenomena will be presented. This will include cyclic tests of unsaturated ore like materials prepared at different densities and degrees of saturation, small centrifuge tests investigating moisture redistribution, 1-D column tests of unsaturated soil subject to shaking and finally the development and results from numerical FE analyses.
