A rotating grooming brush comprising a brush hub having grooming elements and shroud elements, and method for grooming a surface having an unwanted material thereon. The elements extend from the brush hub and may be positioned near its outer periphery. The elements may be grooming elements forming an array and shroud elements forming a shroud array. A rigid or elastomeric shroud extending from the brush hub surface may optionally be included about the edge of the brush hub, to the outside of the grooming elements. Rotation of the grooming attachment brush causes a low pressure region to build in the central area of the brush. This low pressure region creates a resulting force that forcefully attracts the grooming attachment brush to the surface to be groomed. The resulting force is controlled by the diameter of the brush hub, arrangement, of the elements and the speed of rotation.

A system for cleaning a deck that includes: a water supply; a bilge pump connected to the water supply; piping extending from the bilge pump under the deck; and a plurality of water streams emitting from the piping, where the plurality of water streams release over the top surface of the deck. The piping includes a plurality of holes and each hole enables emission of a water stream.

A system for blast-cleaning a barge deck, sides, and fittings providing for safety and avoidance of damage to the barge and to persons, where a barge is blast-cleaned with moving blaster units suspended from and traveling along an overhead track beam. In one embodiment, the moving blaster units are each controlled by a person in a moving operator capsule moving in tandem with a moving blaster unit. In another embodiment, the moving blaster units are robotically controlled from a robotic controller which has access to a three-dimensional plan of the barge, communicating with the robotic blaster units via RF antennae, and receiving real-time data from sensors located on each blaster head. Optionally, the system for blast-cleaning a barge can provide blaster-head cameras for real-time remote monitoring of operations and for recording of the operations allowing review of any issue, such as damage, that might arise.

A system for blast-cleaning a barge bottom providing for safety and avoidance of damage to the barge and to persons, where a barge is blast-cleaned with a blasting tractor having a transverse track beam along which positioning units move blaster heads. In one embodiment, the blasting tractor is controlled by a person in a cab of the blasting tractor, where the operator can see the blaster heads. In another embodiment, the blasting tractor is robotically controlled from a robotic controller which has access to a three-dimensional plan of the barge, communicating with the robotic blasting tractor via RF antennae, and receiving real-time data from sensors located on each blaster head.

A cleaning device that passively self-adjusts to improve biofoul removal across curved, non-uniform, or irregular underwater surfaces. The cleaning device includes a motor, one or more shafts coupled to the motor and coupled to one another via at least one universal joint, and a cleaning mechanism for removing biofoul from the target surface. The cleaning device includes an alignment mechanism that restricts the cleaning mechanism's movement to improve biofoul removal. The alignment mechanism can include bearings, spring components, dampening material, adhesion components, floatation objects, or a combination thereof.
