Title
(EN) SYSTEM AND METHOD FOR DISCHARGE OF BULK MATERIAL FROM A SHIP
(FR) SYSTÈME ET PROCÉDÉ POUR DÉCHARGEMENT DE MATÉRIAU EN VRAC DEPUIS UN BATEAU
Abstract
(EN)
A system for unloading of a powdery cargo (14) from a ship (50) is described, where the ship comprises one or more cargo holds (10) with a bottom (12) of the cargo hold which tapers toward a central point in the cargo hold (10) and also a fluidisation arrangement for fluidising the powdery cargo (14) in the cargo hold (10), such that the cargo flows towards said central point in the cargo hold, in that a pneumatic unloading pump (16) is arranged in or adjacent the central point in the cargo hold (10) at least partially under the bottom (12) of the cargo hold and that the unloading pump (16) is set up to directly receive the fluidised powdery cargo (14). The unloading pump is a pressure tank pump, where the side wall (20) of the pump (16) comprises at least one inlet (18) for the powdery cargo (14), at a height which, in the main, corresponds to the flow direction of the powdery cargo (14), by means of which the powdery cargo (14), with the help of gravitational forces, flows into the pump (16) and fills the pump almost completely or to a level corresponding to that of the cargo hold, and that the pump (16), after filling, is arranged to be pressurised to blow said cargo (14) ashore.
(FR)
L'invention concerne un système pour décharger une cargaison pulvérulente (14) depuis un bateau (50), le bateau comprenant un ou plusieurs conteneurs (10) de cargaison avec un fond (12) du conteneur de cargaison qui diminue en forme de cône en direction d'un point central dans le conteneur (10) de cargaison et également un dispositif de fluidification pour fluidifier la cargaison pulvérulente (14) dans le conteneur (10) de cargaison, de telle sorte que la cargaison s'écoule vers ledit point central dans le conteneur de cargaison, et qu'une pompe pneumatique de déchargement (16) soit disposée dans ou adjacente au point central dans le conteneur (10) de cargaison au moins partiellement sous le fond (12) du conteneur de cargaison et que la pompe de déchargement (16) soit réglée pour recevoir directement la cargaison pulvérulente (14) fluidifiée. La pompe de déchargement est une pompe à réservoir sous pression, la paroi latérale (20) de la pompe (16) comprenant au moins une entrée (18) pour la cargaison pulvérulente (14), à une hauteur qui, sensiblement, correspond à la direction d'écoulement de la cargaison pulvérulente (14), au moyen de laquelle la cargaison pulvérulente (14), avec l'aide des forces gravitationnelles, s'écoule dans la pompe (16) et remplit la pompe presque complètement ou jusqu'à un niveau correspondant à celui du conteneur de cargaison, et la pompe (16), après remplissage, étant agencée pour être pressurisée afin de souffler ladite cargaison (14) à terre.
