Bulk carriers load and unload large quantities of iron ore and coal at bulk terminals. The loading and unloading process on the EMO terminal is largely automated, but for the last 5% an excavator is used to remove material stuck on stairs and walls in the hold. This process takes many manhours, can be dangerous, and can cause damage. The research question is: Is it possible to clean the hold of a coal bulk carrier by machine, and have the hold be cleaned faster and with less damage? A design is made, and based on that a test is set up. The results show that higher pressures, closer distances, and certain nozzle types result in better cleaning, without causing damage. The conclusion is that a hold can be cleaned by a machine with less damage, and possibly faster.
