INLINE ACTIVE HEAVE COMPENSATION

IN GENERAL

The Safelink Inline Active Heave Compensator (IAHC) is built around a passive principle with a gas balanced piston. A passive system does not provide any motion reduction for lifts performed in air as there is no added resistance to change in the objects velocity, e.g. added mass and drag area which are effects seen when payload is submerged.

With the active element the IAHC can compensate any type of load in air by balancing the forces seen by the payload.

The compensator can run both in passive and active mode opening new possibilities for usage, that cannot be matched by traditional AHC systems. It operates from a large battery pack that gives a long operational time when used in active compensation mode. IAHC enables use of low-cost cranes and winches to be used for complicated lifting operations. Further IAHC is well suited as a backup for AHC cranes and being a mobile unit, it is easy to utilize it where needed.
