FlexJoint Drilling Products
Diverter, intermediate and subsea flexible joints for drilling risers, giving omni-directional flexing and reduced riser bending stresses.
Description
FlexJoint products have been used in offshore riser, pipeline and mooring systems since 1976. They provide:
- A leak-proof connection
- Low angular stiffness under high axial tension and pressure
- Reduced riser bending stresses and stack reaction forces
- Omni-directional flexing and vibration damping
Three variants are offered:
- Diverter flexible joint: sits below the diverter housing
- Intermediate flexible joint: double-ended, installed below the telescopic joint
- Subsea flexible joint: couples the riser to the subsea stack
Inspection and repair are available worldwide. Oil States flexible joint technology provided the critical seal when the Macondo well was capped in 2010.
