Abstract

The invention concerns a device for controlling stiffeners (18) of flexible marine pipes, said stiffeners (18) wherein are fitted said flexible pipes (10) are adapted to bend while limiting the curvature of said flexible pipes, said device comprising a deformable rigid rod (26, 34, 42) having a central axis (C), said deformable rigid rod being configured to be embedded in the thickness of said stiffener (18) substantially parallel to said pipe (10), at least two deformation sensors being maintained pressed against the periphery of said deformable rigid rod (26, 34, 42); said deformable rigid rod (26, 34, 42); being maintained locked in rotation about said central axis (C) in said stiffener (18).
