Abstract

A bend stiffener (50) includes an elongate stiffener body (52) having polymer material and two ends. A passage (58) extends through the stiffener body from end to end for receiving and embracing a flexible member (60). The stiffener body includes a coupling (66) for mounting the stiffener body in cantilever fashion. The stiffener body is sufficiently flexible to curve somewhat along with the flexible member under a bending load but is sufficiently stiff to resist excessive curvature which could damage the flexible member, and sufficiently resilient to recover its original shape afterwards. The stiffener body includes at least two stiffener body parts (64a, 64b) defining the passage. Each stiffener body part includes a respective interface member (68, 70) having material stiffer than the polymer material of the stiffener body. A securing arrangement (80, 83) secures the interface members of different stiffener body parts together around the elongate flexible member.
