Title
(EN) DREDGING ASSEMBLY
(FR) ENSEMBLE DE DRAGAGE
Abstract
(EN)
Dredging assembly (1) for reclaiming sand or minerals from a seafloor (9) or for excavating a trench in the seabed (9), comprising an elongated vessel (2), a submersible part (4) and hoisting mechanisms (26, 27, 28, 29) placed on the vessel (2) for from a number of hoist cables (10, 11, 12, 13) lowering the submersible part into the water alongside the vessel, wherein the submersible part is provided with an elongated pump part (5) and an elongated suction part (6) which at its front is connected to the rear of the pump part, wherein at its opposite rear the suction part is provided with a suction nozzle (62) which in the submerged condition of the submersible part rests on the seafloor (9), wherein the dredging assembly is provided with a flexible pipe (8) connecting the vessel and the pump part to each other for pumping reclaimed sand or minerals upwards therethrough.
(FR)
Ensemble de dragage servant à récupérer du sable et des minéraux présents sur un fond marin ou à creuser une tranchée dans ce dernier, ledit ensemble de dragage comprenant un navire oblong, une partie submersible et des mécanismes de levage placés sur le navire afin de descendre la partie submersible dans l'eau le long du navire au moyen d'un certain nombre de câbles de levage, la partie submersible étant pourvue d'une partie de pompage oblongue et d'une partie d'aspiration oblongue qui, dans sa zone antérieure, est raccordée à la zone postérieure de la partie de pompage, la partie d'aspiration étant pourvue, dans sa zone postérieure opposée, d'un buse d'aspiration qui, lorsque la partie submersible est immergée, repose sur le fond marin. Cet ensemble de dragage est pourvu d'un tuyau flexible reliant le navire et la partie de pompage pour faire remonter, par pompage à travers ledit tuyau flexible, le sable et les minéraux récupérés.
