Abstract:
1. A compensating suspension element configuration, which tends to minimize undesirable movements at the top of suspended pipes of a floating production, storage and offloading structure and to facilitate the arrangement of incoming pipes and the correct operation to install and connect these, characterized by the following: a flexible cable extending from said floating structure, said flexible cable, suspended, forms the first upper leg of the compensating suspension element; a flexible pipe extending from said floating structure, which suspended, forms the second upper leg of the compensating suspension element; a Catenary Riser pipe; and a connecting device located in a position so as to connect the flexible cable, the flexible pipe and the riser of the compensating suspension element, said riser extending from said connecting device through a single catenary curve to seafloor, wherein said connecting device imparts stability to the compensating suspension element, the connecting device consisting of a pipe having a bend therein for connecting said flexible pipe and catenary riser pipe at an angle and a connector for said flexible cable, without buoyancy, to maintain a rigid connection between said flexible cable and the floating structure.
