HYDAC Innovation

Ready for cost reduction? Invite us to tell you more about ‘the magic’!

A small actuation cylinder, directly connected to the piston accumulator, compensates for the effi ciency losses. Oil fl ow 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.

Your advantages

This unique HYDAC HeaveCom system has many 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
How does it work

An hydraulic winch with a variable displacement motor operates at a constant pressure difference regardless of the operating conditions. The constant load pressure allows for accumulation of the wave energy inside the HeaveCom cylinder. The cylinder is in force equilibrium with a constant nitrogen pressure on one hand and the constant load pressure on the other. The balance inside the accumulator allows for easy control with a small actuator. The system is actively controlled based on a modified signal from a motion reference unit.
