Passive Compensation
Unloading material safely onto the seabed is a basic requirement in the offshore industry. Passive Heave Compensation Systems (PHC) from Rexroth improve your economic capabilities for loading and unloading with minimal costs.
Unloading material safely onto the seabed is a basic requirement in the offshore industry. Even small waves make it difficult, and, as soon as they are higher than a few feet, it’s almost impossible to work safely. Passive Heave Compensation Systems (PHC) from Rexroth improve your economic capabilities for loading and unloading with minimal costs.
Passive Heave Compensation solutions
A typical PHC device for riser systems consists of a hydraulic cylinder and a gas accumulator. When the piston rod extends it will compress the gas, thereby increasing the pressure upon the piston. Our well designed passive heave compensation systems can achieve efficiencies above 80%.
