Abstract
The end of at least one cable is connected to a float and the other end exerts a tractive effort on one or a number of collecting vehicles which land on the bottom at predetermined points with respect to the point of landing of the ballast which is provided with a pile, anchored in the sea bed, then freed from the float and the vehicle. Means initially secured to the ballast and then detached therefrom serve to convert the upward motion of the float to a displacement of the collecting vehicle along the sea floor.
