This invention provides a system and a method for supporting the operation of subsea installations for 3D reconstruction of flexible pipes () during a direct vertical connection operation, comprising the steps of painting the flexible pipe () with a specific regular pattern, and performing a 3D reconstruction of the points sampled on the flexible pipe () to obtain the radius of curvature of the flexible pipe (), in which the 3D reconstruction comprises the steps of: capturing images of the flexible pipe () during the direct vertical connection operation; sending the captured images to a dedicated computer (); and processing the captured images, generating information on the radius of curvature, wherein the method initially comprises at least one of the following steps: painting the bend restrictor () with a specific regular pattern; painting straps () for buoys () with a specific regular pattern; and painting straps () for the arch bend, in the event of second-end direct vertical connection.

The present invention provides a system for auto-alignment and tensioning of flexible pipes () in a stationary production unit, said system comprising (i) at least one tensioner () comprising an upper cone () and a lower cone (), the upper cone () and the lower cone () being fixed together and forming a symmetrical double cone structure provided with an internally hollow cylindrical opening suitable for passage of a flexible pipe (), (ii) at least one supporting fork () with pivoted connection to the at least one tensioner () and (iii) at least one coupling device () which, at a first end, is connected detachably to the at least one supporting fork () and, at a second end, is connected to the stationary production unit. A method for installing flexible pipes by means of said system is also provided.
