10K Completion Workover Riser Flexible Joint

Product Information

LORD® Flexible Joints can be deployed with Intervention Workover Control Systems (IWOCS) and the associated riser system to accommodate the motion of the intervention / workover vessel relative to the subsea wellhead. A flexible joint can replace a stress joint in this application, supporting the tension in the riser and containing pressure, yet offering a much lower bending stiffness. When used to replace a traditional bottom stress joint, the significantly lower moment imparted to the wellhead allows the operator to perform more workovers per well, thereby extending the life of the field.

Flexible joints can also be deployed at the surface in an IWOCS system. The entire flexible joint is just over five feet in height, enabling smaller intervention vessels to operate a top-tensioned riser without a stress joint or a telescopic joint. This lowers costs compared to performing high-pressure interventions with a drilling rig.

Features and Benefits

  • Features unique dual bearing design
    • Seal bearing optimized for high-pressure containment and fluid resistance
    • Load bearing optimized for low rotational stiffness and fatigue strength
    • Load bearing functions as a redundant seal to improve reliability and capability over a single-bearing design
    • Provides a failsafe mechanism unavailable with a stress joint, conventional flex joint, or other components of the riser system
  • Rated to 10,000 psi and hydro-tested to 15,000 psi
  • Lower bending stiffness reduces wellhead fatigue, extending field life
  • Compact height (just over 5 feet) enables use on smaller intervention vessels
  • Fielded on multiple intervention vessels
  • DNV-certified
  • High-pressure high-temperature (HPHT) versions available (>350°F)
  • We apply aerospace-proven processes and quality systems to Oil & Gas products to ensure each part performs consistently and reliably
