A protection assembly for mounting in an underwater support structure includes at least one bend protection device coupled to a retaining device so that together they provide a through-going passage for receiving an elongate member which is to be protected. The elongate member passes through a support structure opening, and the retaining device is configured to be received in the support structure opening and to engage with the support structure to resist subsequent withdrawal from it. Installation of the protection assembly includes grasping the protection assembly with a releasable clamp, arranging a pulling line to pass through the support structure opening to the mechanical clamp and securing the pulling line to the mechanical clamp, drawing the retaining device of the protection assembly into the support structure opening using the pulling line and engaging the retaining device with the support structure, and releasing the clamp from the protection assembly.

In order to achieve the objects described above, the present invention provides an adapter tool for coupling a ben stiffener with interface for bell mouths of models with connection type BSN900E in a diverless bell mouth (BSDL), consisting of a adapter split ring (1), guide pin holes (C), fastener eyes (D), and through holes (E). The adapter tool is capable of keeping interchangeability and flexibility between projects or project phases, even if different bellmouth models are used. The interconnection method between the helmet (9) and the adapter split ring (1) can be done by direct attachment by bolt, or by attachment by ring/rod support. Both interconnections can be made on board a flexible line launching vessel, in the case of reusing lines from other projects, or at the factory, in the case of sharing new flexible lines.

A mounting device (110) for an elongate flexible member extending through an aperture (102), comprising: an elongate body (130) having a longitudinal axis; an internal passageway passing through the elongate body (130) parallel to the longitudinal axis, for receipt of the elongate flexible member; a plurality of apertures (132) in the elongate body (130); an engagement member (136) in each apertures (132) and constrained to move along a displacement axis inclined to the longitudinal axis of the elongate body (130); a plurality of actuation members (142), each engaged with a respective engagement member (136), whereby displacement of the actuation member (142) in a first direction displaces the engagement members (136) outwardly to project beyond the periphery of the elongate body (130) and displacement of the actuations members (142) in a second, opposite direction displaces the engagement members (136) inwardly; and biasing means (182) biasing the actuation members (142) in the first direction.
