The tension ring is used to apply tension on the riser string.

Design Philosophy

The KT tension ring combines the functionality of a tension ring and the termination joint. It simplifies running and retrieving the marine riser by eliminating makeup/breakout of tensioner lines and hydraulic hoses in the moon pool area.

Applications

• Floating Drilling Unit

Product Characteristics & Benefits

• Choke, kill and auxiliary line terminations are
• permanently connected
• Orientation pins engage slots in the telescopic joint line termination housing for easy makeup
• Permanently installed tensioner lines maintain proper orientation with rig drilling tensioners
• Riser tensioner lines remain attached to the KT ring
• Thrust and radial bearings permit rotation of the vessel relative to the riser string
• Optional fluid bearings minimize breakout torque
• Auxiliary line pins have differential seal areas to ensure fail-safe engagement
