Method and installation for depositing materials on an ocean bed in accordance with a given line in which the autonomous vehicle is displaced on the ocean bed by accurately following said line whereby the vehicle is provided with a hopper, a ship is moved on the surface of the ocean roughly in accordance with said line, the materials are discharged from this ship towards the hopper and are guided by means of a pipe suspended beneath the ship and whose lower end is not integral with the hopper, wherein the propulsion means of the pipe disposed at the lower end thereof are operated so that the lower end of the pipe is forced to remain above the hopper.
A method of depositing materials on an ocean bed by a given line, in which an autonomous vehicle is displaced on the ocean bed by accurately following said line and the vehicle is provided with a hopper, a ship is moved on the surface of the ocean roughly in accordance with said line, the materials are discharged from said ship towards the hopper and are guided by means of a pipe suspended beneath the ship and whose lower end is separate from the hopper, wherein the the presence of the hopper is detected by detection means disposed at the lower end of the pipe, the lower end of the pipe being moved by its own propulsion means controlled by said detection means so that the lower end of the pipe is forced to remain above the hopper without mechanical connection with the latter.
An installation for depositing materials on an ocean bed, comprising:
