Abstract Liquefaction of mineral ores, such as iron ore and nickel ore fines, resulting in cargo liquefaction and hence displacement (‘cargo shift’) leading to loss of ship stability, has been a major cause of marine casualties. In the paper, rolling response in regular waves for a 2D rectangular hold, partially filled with moist bulk cargo is investigated, by applying a simulation approach based on an adapter that couples a CFD code and a DEM (‘Discrete Element Method’) code. A parametric investigation is undertaken to identify the key parameters that trigger cargo and ship instabilities.
