Innovative Active Heave Compensation

Innovative Active Heave Compensation


Innovative Active Heave Compensation

Existing rotating hydraulic winch systems are now easy to convert to the HeaveCom System. New HYDAC technology saves on energy consumption, mass, nitrogen supplies, reduces wear throughout the entire system & extends the area of your application.

Advantages over traditional heave compensation

  • Up to 85 % more energy efficient
  • Optimized construction
  • No on board nitrogen generation required
  • Less overall wear
  • Existing hydraulic winches can easily be transformed
  • into the Active HeaveCom System
  • Easy to confi gure as a redundant system
  • Less installed hydraulic power
  • Emergency load holding winch

A small actuation cylinder, directly connected to the piston accumulator, compensates for the efficiency losses. Oil flow to the winch motors is regulated based on a modified MRU-signal. The method results in an energy saving up to 85%. Existing rotating hydraulically driven winch systems are easy to convert to the Heave-Com System. Parallel installation of HYDAC AHC-drive on a winch system provides redundancy to the AHC-system. Direct wear throughout the entire system is reduced, since there is no more need for additional cable disks.
