Abstract: A material distribution vessel for distributing material recovered in a dredging operation is disclosed. The material distribution vessel includes a hull; a propulsion system for selectively moving the hull through a waterway; and a conveyor system supported by the hull. The conveyor system has a first end for receiving recovered material and a second end for depositing the recovered material. At least a portion of the conveyor system is movable relative to the hull to move the second end to a desired position. The material distribution vessel also includes at least one support pad. The at least one support pad is movable in at least a vertical direction to support the hull on a bottom of the waterway. The recovered material may be deposited into the waterway to form an island (which may be a levy), into another water-borne vessel, or into an on-shore station such as a wheeled transportation vehicle.

Abstract: A system for transporting material recovered in a dredging operation performed by a dredge is disclosed. The system includes a water-borne material distribution vessel including a conveyor system for receiving and depositing the recovered material. It also includes at least one water-borne material transportation vessel for transporting recovered material from the dredge to the material distribution vessel. The water-borne material distribution vessel can deposit the material into the waterway to form an island (which may be a levy), into another water-borne vessel, or into an on-shore station such as a wheeled transportation vehicle.

Abstract: An elongated narrow bulk delivery and depositing bouyant conveyor belt device is operable to shore up bridges, docks and/or piers in environments having operating space confined by low overhead and narrow berths between adjacent spaced apart pilings. The bouyant conveyor belt structure is alternately extendable and retractable in each of shallow and deep water. The bouyant conveyor belt structure is stabilized by one or between two linear axially extending substantially parallel sides of spaced apart floating platform barges. The barge(s) typically mount hopper and vibratable chute structure receivable of bulk typically rip rap fill material and feedable thereof onto the bouyant conveyor belt structure, thereafter deposited by a revolving of the conveyor belt structure.
