The invention relates to a system and a method for supporting the operation of subsea installations for 3D reconstruction of flexible pipes (1) during a direct vertical connection operation, comprising the steps of painting the flexible pipe (1) with a specific regular pattern, and carrying out a 3D reconstruction of the sampled points on the flexible pipe (1) in order to obtain the radius of curvature of the flexible pipe (1), in which the 3D reconstruction comprises the steps of: capturing images of the flexible pipe (1) during the direction vertical connection operation; sending the captured images to a dedicated computer (4); and processing the captured images, thereby generating information about the radius of curvature, and in which the method initially comprises at least one of the following steps: painting the bend restrictor (6) with a specific regular pattern; painting straps (71) for buoys (7) with a specific regular pattern; and painting straps (71) for the arch bend in the event of second-end dir
