CWOR | IWOCS

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. Flexible joints can also be deployed at the surface in an IWOCS system.

 

Features & Benefits

  • Features unique dual bearing design
  • 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)

Drilling Riser Flexible Joints

LORD® flexible joints accommodate the motion of the rig relative to the subsea wellhead.
 
Features & 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
  • HPHT versions available (>350°F)

Steel Catenary Riser (SCR) Flexible Joints

LORD® SCR Joints accommodate the heave and roll of the vessel motion, reacts the weight of the riser itself, and contains production fluids under pressure.

 

Features and Benefits

  • We offer a lower bending stiffness for a given load rating, imparting lower stresses on the vessel at the attachment point

Tendon Bearings

LORD® Tendon Bearing connectors attach the tendon to the vessel and the sea floor while accommodating the lateral motion of the vessel due to ocean currents. 

 

Features & Benefits

  • Easily customizable to serve challenging applications
  • LORD connector bearings installed on the Jolliet platform are still in service today

Replace Tapered Stress Joints With Proven 10K Flexible Joints in Subsea Oil and Gas

Maintaining subsea equipment can be a complex and expensive endeavor, particularly in deepwater operations. Riser-based well interventions and workovers are necessary operations that while significantly improving production, can also induce considerable fatigue on the wellhead. Learn more.
