Véhicule sous marin pour le ramassage et la remontée de matériaux reposant sur un fond marin à grande profondeur. Le véhicule se caractérise en ce qu'il comprend une structure porteuse (2) réalisée en un matériau de flottablité, ladite structure ayant la forme d'un anneau présentant un plan de symétrie longitudinal et définissant l'étrave (2a), l'arrière (2b) et les flancs (2c et 2d) du véhicule et ménageant ainsi un espace libre central, la face externe de la structure (2) réalisant la carène du véhicule. Des silos de stockage (16a...16n) sont ménagés dans l'espace central. Le véhicule comprend également des élément de ramassage (14) disposés en avant de l'étrave et des propulseurs principaux (12) fixés sous la structure porteuse. Application au ramassage de nodules polymétalliques.
