Abstract

In order to reduce the risk of accidents resulted from easy liquefiable solid bulk cargo, the suitable transportation conditions of easy fluidized solid bulk cargo were evaluated by using scientific methods. Based on the annual average wave spectrum of each main sea area and the calculation method of ship sway motion, the external environment oscillation load of cargo during transportation was studied by the wave energy theory, the load threshold value of safe transportation in different navigation areas was proposed, and the ratio between the actual load and the load threshold was taken as the quantitative standard to judge the water transportation safety , and to verify its reliability, therefor to predict the transportation safety of the easy fluidization solid bulk cargo, which provides a reference for the sea transportation of the bulk cargo ship./p>
