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. Invite us to tell you more about the magic of our new HeaveCom System; your advantages, the costs and everything you need to know!
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.
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.
