Patent number: 11946324Abstract: 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.Type: GrantFiled: May 20, 2021Date of Patent: April 2, 2024Assignee: Petróbras Brasileiro S.
