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 (10) 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 (40). 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.
