The Active Heave Compensation system (Heavetronic®) was specially developed by Liebherr for deep sea operations and is available for Liebherr Ram Luffing Knuckle Boom Cranes (RL-K Series).
Heavetronic® is fully integrated in to the Liebherr Litronic control system and supports not only safe lifting but also safe lowering of loads. Liebherr’s patented Pactronic® Hybrid Drive provides the system power requirements to remove the effect of the sea motions.
Functional Principle
The system is based on a motion reference unit (MRU) for registering and evaluating the current wave movements that affect the ship and thereby the crane.
Based on the measurements of these movements, a prognosis of the vertical movement of the crane boom tip is carried out. The movement of the winch is then proactively and automatically controlled to keep the load stable in relation to the seabed.
Subsea Winch
The Liebherr-developed deep sea winch makes it possible to work up to 3,600 metres below sea-level. It features a special rope reeling mechanism that facilitates low-wear during rope motion prolonging the service life of the rope.
Advantages at a glance
Improvement in efficiency of subsea lifting Controlled and safe handling of loads Minimization of dynamic loads on the crane Integration in the Liebherr Litronic control system
