Designed to maintain the drilling riser string in tension on floating vessels

Cameron wireline riser tensioners are currently available in three versions. The 160,000-lbf, 200,000-lbf, and 250,000-lbf double-wire rope tensioners include idler sheaves, wire, rotating deadline drum, valve block skids, air pressure vessels (APVs), control system, antirecoil, and optional air compressors.


  • Compact and robust mechanical design
  • Easy maintenance at defined points
  • Hydraulically driven deadline drum for simplified wire replacement
  • Manifold valve blocks to reduce the amount of piping and number of leakage points
  • State-of-the-art antirecoil valve with flow shutoff function for safer normal and disconnect operations
  • State-of-the-art tensioner cylinder rod coating for harsh marine environment
  • High degree of redundancy in the system
  • State-of-the-art redundant control system to ensure an efficient, safer, and smooth operation
  • Separate filling and draining unit for easy and safer filling and draining of compensation fluid
  • System operation from the drilling control room (DCR) and a local operator panel in the moon pool area
