Abstract

Cet appareil comprend un ensemble d'attaque et un ensemble de dragage. L'ensemble d'attaque comprend plusieurs buses 9 adaptées pour diriger des jets d'eau sur le fond de la mer afin d'en enlever la matière localement par érosion au voisinage de l'ensemble d'attaque, et l'ensemble de dragage 11, 12, 13 enlève la matière enlevée par érosion au voisinage de l'ensemble d'attaque. De préférence les buses sont telles que des jets d'eau sortent de l'ensemble d'attaque dans des directions différentes et/ou variables.
