ABSTRACT:
Method for placing two submerged elements in a relative determined position, particularly in view of their mutual connection, comprising a first step of controlling the relative displacement of said elements on the basis of the measurement of electric values so as to ensure the alignment of a central point of one end of one element with the longitudinal axis of the other and a second step of progressively bringing the two elements in contact with each other by their relative displacement controlled on the basis of the measurement of their relative distance and mutual inclination angle, by means of acoustic emitters-receivers.
