摘要

Method for laying or / and recovering a line in a body of water comprising a controlled immobilization phase and associated system This method comprises the following steps: - supply of a laying device comprising two upstream gripping members ( 72A) opposite and two downstream gripping members (72B) opposite, defining a passage (73) for the circulation of the line (12); - descent of the line (12) to at least one immobilized position; - immobilization of the line (12) in the or in each immobilized position; and, before the or each immobilization of the line in the immobilized position: - limited overshoot of the immobilized position downwards to reach a position for changing the direction of movement; - time delay in the change of direction of movement position; - limited rise of the line (12) from the position of change of direction of movement to the immobilized position.
