ABSTRACT:
A method for removing surface coatings from the hull of a ship by focusing annular streams of ultra-high pressure water from a rotating nozzle having one or more orifices. The nozzle orifices have oblique angles from the central axis of the rotating nozzle whereby the force of the water leaving the nozzle through the orifice imparts an opposite rotational force to the rotating nozzle. The placement of the orifices on the rotating nozzle is done in such a manner that the annular streams of water act in concert when striking the working surface to remove the paint. A waste water recovery system collects waste water and particulates of paint stripped from the working surface, the particulates are removed for later disposal and the water is recycled.
