Dynamic flexible risers, power cables and umbilicals may be connected to a rigid structuresuch as a subsea riser base or the turret exit of a floating production vessel. The presence ofenvironmental loads subsequently causes the riser to flex about this fixed location. Thismovement, in combination with large axial loads may cause damage to the riser structuredue to overbending and fatigue.
We produce individually designed integral bending stiffeners for rigid riser end fittings. Theseconically shaped polyurethane moldings add local stiffness to a riser, flowline, cable or umbilical tolimit the bending stresses and curvature to acceptable levels.
Features
The bending stiffener has a conical external profile and a central hollow cylindrical section allowing it to slide over the end of the riser.
Each bending stiffener is designed individually to protect the riser minimum bend radius (MBR) under the defined tension and angle combinations, meeting the loadcases (tension vs angle) of each application and are specified as either dynamic or static depending on their intended use.
