Abstract: The present invention addresses to a system for supporting the tension load of the riser, this component with the primary function of supporting the risers, where the riser support mechanism is an integral part of the upper cone, thus eliminating the need to install slips by the shallow dive, and, also avoiding that the locking mechanism is an integral part of the Top Termination of the Riser (L). There is a minimal number of moving parts, which favors the maintainability of the system. In addition, if maintenance is required, the size and weight of the components are compatible with diving operations. For pull-in operations, it is anticipated that the slips will return to their working position only by the action of the force of gravity. In the case of pull-out, the concept of automated slip retraction mechanism was developed.

Abstract: The present invention comprises a structure with the same external geometry as a generic hook, but with a topology (internal structuring) that allows a greater distribution of deformation energy to all elements of the part, with load transfer to other less stressed regions. When the present invention is subjected to a loading, said flexible parts deform in a pre-specified manner, transferring part of a loading that would be excessive in a given region to another less loaded region, without any power supply or external interference. In this way, the deformation pattern that occurs in the present invention relieves stresses where they are greatest and, at the same time, provides flexibility (compliance), more adequately distributing coupling loads between the various fastening components.

Abstract: The present invention provides a system for coupling between a bend stiffener (1) and a bell month (2) comprising a plurality of locking mechanisms (3), wherein each locking mechanism (3) is secured externally to the bell mouth (2) and comprises a movable lug (30) positioned such as to slope downwards, in which the lug (30) accesses the interior of the bell mouth (2) and is actuated by an elastic element (34) designed to exert pressure on the lug (30) in the direction of the interior of the bell mouth (2).
