ABSTRACT:
A device is disclosed for in-water cleaning of a ship's hull. The device includes a body having inboard and outboard faces joined by a peripheral side, the faces having coaxial central apertures which are joined to form a central opening through the body, in which is mounted a hydraulic motor-driven propeller. The propeller maintains the device in contact with the hull during cleaning. There are detachable wheel modules recessed into the body to propel the device along the hull and a hydraulic motor-driven steering wheel to steer the device. Hydraulically driven cleaners are mounted on the inboard face to clean the hull. There is also a light recessed into the peripheral side to provide illumination to the hull. The device may also include an adjustable buoyancy chamber mounted on the body to provide sufficient buoyancy to the device to enable the device to effectively clean the hull at the waterline. Also disclosed is a unique double bearing for mounting each of the wheels, cleaning means and propeller which prevents hydraulic fluid leakage and permits easy demountable of the compounds.
