Adapter tool for coupling a bend stiffener with interface for bell mouths of models with BSN900E type connection in a diverless bell mouth (BSDL) and interconnection methods

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.
