Some bulk carriers have suffered accidents due to transporting cargo with potential liquefaction, which is classified as Group A material in the International Maritime Solid Bulk Code (IMSBC code). Bauxite has similar liquefaction behavior during shipping. However, Bauxite is not listed as Group A yet. In order to update the schedule of the IMSBC code, and provide more reliable guidance to the shipping industry, further studies are warranted to verify and expand on the liquefaction of bauxite. This study is of great significance to illustrate bauxite carrier accidents and to prevent the occurrence of new accidents. At first, general properties of bauxite were reviewed, then the distribution of moisture content was identified according to the statistical data; moreover, properties of other samples were compared with those of other bauxite, such as saturation, particle distribution, compactness and density. Third, an experimental analysis was performed based on bench of vibration and rolling device. The results show that the range of moisture content in the IMSBC rule is lower, the density range is smaller, and the classification of Group C is improper. Especially, the liquefiable characteristics of bauxite were verified, and the critical moisture content of liquefaction was found. As a conclusion, a proposal for amending the relevant items of the IMSBC code was produced based on this contrastive and experimental study of the characteristics of bauxite during shipping.
