<p>A system for recovering immerged sediments from a seabed and discharging them. From a free sailing extraction ship a mixture of water and sediment is suctioned by a submerged pump unit through a flexible hose adapted to be rolled on a rotative reel positioned on the extraction ship, while the ship is sailing over the concession. The suctioned mixture is then immediately delivered to one of a series of free sailing carrier and transport units that sail alongside.</p>
