In order to achieve the above-described objectives, the present invention provides an adapter tool for coupling a bend stiffener with diverless bell mouth (DLBM) interface in a bell mouth with BSN900E-type interface. The adapter tool is capable of maintaining interchangeability and flexibility between designs or design phases, even if different bell mouth models are used. A tool characterized in that it comprises an adapter split ring () that, in the upper part, has a geometry compatible with the dovetail profile of the BSN900E model helmet and, in the lower part, has a geometry compatible with the seating profile of the DLBM helmet (). The present invention leads to two assembly methods, which guarantee the operational safety of the adapter assembly, namely: a method where it is only done by screws located in the split ring; and another, where the assembly includes, in addition to the split ring, an assembly with the support ring and rods.

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 (), 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 () and the adapter split ring () 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.
