Performance Evaluation of a Floating Matter Recovery System using Water Level Difference on a Catamaran type Water surface Cleaning Ship with a Movable Weir

Abstract

This research aims to develop a new water surface cleaning ship that can efficiently collect floating matter of various sizes and liquids floating matter such as oil on the water surface not only in forward and backward motion but also stationary state. The proposed water surface cleaning ship is not a mechanical type, but can capture floating matter by using the flow generated by the water level difference inside the ship by means of a control free movable weir the results of the water level difference measurement test showed that the higher the weir height of the movable weir, the greater the water level difference, regardless of the length of the net of the floating matter recovery device installed inside the scaled model ship.
