Conveyor-based marine debris collection has to be enhanced. Due to their wide form, ability to flow water, and minimal weight, hollow-winged conveyors can be an alternative. This investigation was carried out to find out how effective the hollow wing approach is at collecting marine debris in the ship's conveyor. This involves a catamaran type with a hollow-winged static conveyor. The hollow wing model is used in four different ways. The circle hollow wing model 18.75 cm 60 deg has a higher marine debris collecting ratio than other models, according to the results.
