Bending stiffener (1) intended for mounting to a receiving station, preferably an offshore platform, for guiding cables, flexible risers, umbilicals etc. through an internal axial bore (6) in the bending stiffener (1). The stiffener (1) comprises a termination end (14) for mounting to the receiving station, a circular flange (3) with an inner bore provided with an internal cylindrical insert (4) having an internal bore diameter equal to the bore (6) of the bending stiffener (1), a composition (7) of a rubber compound with an internal bore (6) and outer dimensions equal to the bending stiffener (1) is fastened to the end flange/insert (2, 4) and is formed in the longitudinal direction with a substantially conical outer taper toward the flexible end (13) of the bending stiffener (1). The composition (7) further including layers of axial reinforcement (8) connected with cross-cord layers (9) therebetween, reinforcement (11), and an outer protection layer (12) wrapped around the outer circumference of the bending stiffener (1). The flange (2) is formed with a number of radial openings (windows) (3) distributed around the flange (2). The axial reinforcement (8) runs from the flexible portion (13) of the bending stiffener (1) toward and through a radial opening (3) in the flange (2) and back toward the flexible portion (13) of the bending stiffener (1) through another radial opening (3) in the flange (2). |
