Abstract: The invention relates to a protection assembly for mounting in an underwater support structure, and to a method of installing such an assembly. According to one aspect of the invention, the protection assembly comprises at least one bend protection device (20a, 20b) coupled to a retaining device (18). The bend protection device (20a, 20b, 26) and the retaining device (18) together provide a through-going passage (32) for receiving an elongate member which is to be protected. The support structure (12) has an opening (16) through which the elongate member is passed, and the retaining device (18) is configured to be received in the opening (16) in the support structure and to engage with the support structure to resist subsequent withdrawal from it. Installation of the protection assembly comprises grasping an end portion of the protection assembly with a releasable clamp (100), arranging a pulling line to pass through the opening in the support structure to the mechanical clamp and securing the pulling line to the mechanical clamp (100), drawing the retaining device of the protection assembly into the opening (16) in the support structure using the pulling line and engaging the retaining device with the support structure, and releasing the clamp (100) from the protection assembly.
