LORD® riser tensioner bearings are laminated bearings that react loads in the riser tensioner system. We have two types of bearings for riser tensioner systems: Riser Tensioner Cylinder Bearings and Riser Tensioner Frame Bearings.
Riser Tensioner Cylinder Bearings Features and Benefits
• Reduces side loading on cylinders by 90% in normal operation and by over 99% in seized scenario. Reduced loads translate to less wear on the seals, and thus less downtime to service the cylinders.
• Eliminate stick-slip phenomenon associated with hard bearings and shackles
• Lasts for 20-25 years
• Easily adaptable to current systems
• Can be used on push-up or pull-up configurations
• Fielded on world’s first TLP in 1984
Riser Tensioner Frame Bearing Features and Benefits
• Custom solutions available for any application
• Reacts tensioner loads while accommodating motion in the radial plane
• Minimizes stress on the deck and frame/cassette, saving weight by reducing the need for deck reinforcement
• Combines proprietary design and elastomer formulation to handle high loads and motions in a small footprint
• Prevents excessive motion during survival events
