INLINE ACTIVE HEAVE COMPENSATORS
The SAFELINK Inline Active Heave Compensator (IAHC) is a hook-based, self-contained, mobile system offering a high degree of flexibility without requiring a permanent AHC installation on the crane.
The IAHC operates autonomously and can be set up, controlled, or overridden via a handheld tablet with wireless communication redundancy.
The IAHC provides active motion compensation for all types of structure lifts, regardless of geometry or mass. The IAHC can for example be used to unload components at sea by a WTIV from a feeder barge during offshore wind farm installation, increasing the operational weather window substantially.
TECHNOLOGY
The Safelink Inline Active Heave Compensator (IAHC) is built around a passive principle with a gas balanced piston. A passive system however 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 added 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. It operates from a large battery pack that gives a long operational time when used in active compensation mode.
IAHC enables use of standard cranes and winches to be used for complicated lifting operations. It also reduces wire wear of AHC cranes. In addition, the IAHC is well suited as a backup for AHC cranes and being a mobile unit, it is easy to utilize it where needed.
KEY BENEFITS
Controlled Quick Lift: Prevents re-hit risks during feeder vessel operations with optimized S-curve motion.
Constant Tension: Maintains steady line loads during vessel-to-vessel transfers, reducing dynamic shock loads.
Active Heave Compensation: Achieves >95% motion and velocity reduction for smooth, safe landings.
Passive Heave Compensation: Integrated fail-safe backup for added reliability.

PROVEN OFFSHORE PERFORMANCE
The SAFELINK Titan IAHC is field-proven, with the world’s largest IAHC (1250t) in full operation and over 600 successful offshore lifts. It supports floating-to-floating, floating-to-fixed, and fixed-to-floating operations, and is scalable for next-generation offshore wind turbines. We have demonstrated a huge saving per vessel through reduced downtime.
Operator-Friendly Design
– Fully Autonomous Operation with redundant wireless tablet control
– Seamless Integration with internal lifting tools possible
– User-Friendly Setup & Monitoring for enhanced safety for crew and vessel
