INLINE ACTIVE HEAVE COMPENSATION
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.
It operates autonomously and can be set up, controlled, or overridden via a handheld tablet with wireless communication redundancy.
The IAHC solution provides active motion compensation for all types of structures, regardless of geometry or mass. The IAHC can be used to unload components at sea by a WTIV from a feeder barge during offshore wind farm installation, increasing the operational weather window substancially.
TECHNOLOGY
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.
The SAFELINK IAHC is a patented and inhouse developed technology, which can be utilized for the following:
VESSEL TO VESSEL LIFTS
● Synchronized active heave compensation using external wireless MRU
SPLASH ZONE CROSSING DYNAMIC FORCES
● State of the art splash zone mode with continuously adjusted hydraulic damping ensures lowest possible dynamic force
SUBSEA RESONANCE
● Low spring stiffness offsets the natural period to avoid resonance
SUBSEA LANDING
● Active landing compensation reduces speed to close to zero
WIRE ROPE FATIGUE PREVENTION
● Removes AHC induced fatigue
