MATERIAL HANDLING SYSTEMS AND METHODS

A system comprising:a) a first work vessel (4) and a wing tool (2) operable from the first work vessel, the wing tool comprising one or more thrusters (6,8) having power and capacity to fluidize sediments from a first seabed location (32) and move the fluidized sediments to a second seabed location (42), the second seabed location including a depression designed for the collection, concentration and extraction of bottom sediment material previously made by the wing tool or an extraction pump (40), the depression allowing a settling period between fluidized sediment arrival and extraction pumping during which gravitational settlement of the fluidized sediment creates a denser extraction stream with less water;b) a second work vessel (34) comprising the extraction pump, the extraction pump operable from the second work vessel and having capacity to pump at least a portion of the denser extraction stream from the depression and form a collected sediment comprising sand, fine grain materials, and water; andc) the first work vessel and/or the second work vessel comprise a hull that is configured to be disassembled and transportable in one or more shipping containers or on one or more trucks.
