ANALYSIS OF A FLEXIBLE-RISER TOP CONNECTION WITH BEND RESTRICTOR

The connection of a flexible riser to the floating production system is a critical area with respect to extreme deformation and fatigue. One of the proposed means of preventing failure of the flexible pipe at this point is to apply a tapered polyurethane collar around the pipe, termed a 'bend restrictor'. For the design and analysis of this bend restrictor, two models were developed: one based on slender beam theory and a full finite-element model. The slender beam model provides an efficient design tool, although finite-element analysis remains necessary to check the final design.
