Abstract: Systems and methods include a wing tool configured to be operable from work vessel(s), the wing tool including thrusters capable of fluidizing sediments from a first seabed location and moving it to a second seabed location, the second seabed location including a trench or differently shaped collection sump previously made by the wing tool and/or an extraction pump. The extraction pump operates from a second work vessel having sufficient capacity to pump fluidized sediments from the trench. Certain systems include a separation unit that separates sand from silts and clays and water from collected sediment. Systems and methods for reclamation of reservoirs, moving sand waves, for pre-trenching and/or recovering marine pipelines and cables, for removing cover from marine archaeological sites and for disposing of contaminated bottom materials in an environmentally acceptable manner.

Abstract: A system for dredging underwater sea-beds includes a floating platform; a dredging tool positioned on the platform to face the water and having a system that lowers and lifts the dredging tool, further having at least three connection points associated with the platform to connect the ends of warping cables that are anchored to the shore at the opposite ends, and further having tensioning devices; a sediment collection system that collects sediment captured by the dredging tool; a system detecting the position of the platform; a system detecting the position of the dredging tool; a system detecting seabed configuration; a system detecting the quantity of sediment removed from the seabed; a remote command and control system for the system that lowers and lifts the dredging tool, a tensioning system for the warping cables; a detection system; and a system that supplies the equipment on board of the platform.
