The CTT is designed to ensure and maintain pre-set tension in a riser system during operation. 

The upward force is provided by hydraulic operated cylinders, which react against a load bearing plate in the work frame.

The hydraulic jacks are operated by a local control unit which can records the CTT elevation height and applied top tension vs time. Alarms can be set and the operational data can be downloaded after the operation.

CTT are available in range from 100-400 ton.

CTT is field proven and can be used for:

  • Conductor tension                                                                                                
  • Work over riser tension
  • HP drilling riser tension
  • Casing/Tubing jacking
