Title
(EN) A DREDGE VESSEL SYSTEM FOR DEEP-SEA DREDGING
(FR) SYSTÈME DE NAVIRE DE DRAGAGE POUR DRAGAGE EN HAUTE MER
Abstract
(EN)
The application is directed to a system for recovering immerged sediments (3) from a concession and discharging them. From a free sailing extraction ship (1) a mixture of water and sediment is sucked by a submerged pump unit through a flexible hose (7) adapted to be rolled on a rotative reel (5) disposed on said extraction ship, while the ship is sailing over the concession. The sucked mixture is then immediately delivered to one of a series of free sailing carrier and transport units (27) that sails alongside.
(FR)
Cette invention concerne un système de récupération et d'évacuation de sédiments immergés (3) depuis une concession. Un mélange d'eau et de sédiments est pompé par une unité de pompage immergée, à partir d'un navire d'extraction autonome (1), à travers un tuyau flexible (7) conçu pour être enroulé sur un dévidoir rotatif (5) disposé sur ledit navire d'extraction, pendant que le navire navigue sur la concession. Le mélange pompé est ensuite directement acheminé vers une unité parmi une série d'unités autonomes de transport maritime (27) qui naviguent le long dudit navire.
