ARTP E-Series Back-up Compensated Tension Lift Frame

The top of the line ARTP E-Series is an integrated Tension Frame which is able to provide passive or back-up heave compensation, incorporating ICON’s unique control valve arrangement for rapid completions workover riser (CWOR) or Subsea Landing String (SLS) protection.

The E-Series is best suited for workovers and completions in harsh operating sea states, where primary or back-up compensation is required with large (up to 10m) stroke capacity.

Key Benefits:

  • API 8C and DNV compliant

  • Suitable for load ratings from 500kips - 1500kips

  • Simple functionality to operate as passive or back-up heave compensator

  • Automatic over and under tension protection, providing rapid back-up heave compensation

  • Simple robust system with in-built redundancy and failsafe mechanisms to ensure no single point failure 

  • Customised equipment configurations to suit varying derrick arrangements

  • Interchangeable interfaces to surface equipment (I.e. Surface Flow Tree), with minimum stack-up height consumption

  • Fixed PCE operating window complete with man-rider and utility winches as required
