The Chronos IAHC is a mobile, rugged, all-in-one active heave compensator designed to provide motion compensation for all types of structures independent of geometry both subsea and in air.

Compensating all heave motion directly at the crane hook enables the offshore industry to significantly reduce costs, gain efficiency, increase lifting and subsea lowering capability and increase productivity through minimizing downtime

The Chronos IAHC is a revolutionary lifting tool for increasing safety and reducing cost of marine operations.

Chronos IAHC has numerous novel features to ensure outstanding performance, safety and usability:

  • One time filling
    The compensator only requires a one-time filling of N2, the system is self-contained and will re-stock itself. Hence there is no need for any N2 supply in addition, removing the need for N2 racks / bottles.
  • Compensator setup
    Setup and filling is easier and safer with Safelink’s step by step digital setup guide. The tablet validates that filling is done correctly, and all data from the lifting operation can be retrieved to verify actual dynamic loads and landing speed.
  • Adjustable damping
    The compensator has changeable damping settings which will be optimized throughout the lifting operation
  • Rod locking
    The piston rod can be locked and unlocked remotely via the tablet or via the programmable ROV switch when required during the operation.
  • Buoyancy and depth compensation
    The internal gas pressure is automatically adjusted to compensate for environmental changes throughout the operation.
  • ROV control and acoustic communication
    The unit has a ROV panel fitted with switches and display for interaction and communication with ROV. The switches can be pre-defined to different tasks. Acoustic two-way communication can also be enabled to interact with the mobile AHC.
