ABSTRACT:
A trolley to convey brushes for cleaning a stationary hull is drawn along the bottom and sides of the hull. Brushes are supported by variable buoyancy chambers to make the biasing of the brushes against the hull also in turn variable. The trolley can be supported and stored in a dock or alternatively supported by a floating platform. There is an electrical motor drive for a chain which pulls the trolley. A diesel prime mover may be used in the floating platform to generate power for the electric motor chain drive and for the submersible motors.
