Waves create a vertical ship movement (heave). This causes a third dimension to motion equation. Heave compensators reduce the effect of vertical ship heave on the drill string and coring tools. Without heave compensation, optimal ocean coring and borehole completions would require calm seas, with large amounts of downtime spent waiting on weather.
We offer valve solutions for active and passive Heave Compensation:
- HS-AHC: Active Heave Compensator Control valve system
- HS-PHC: Passive Heave Compensator Control valve system
Our compensator controllers have been designed with focus on safety, reliability, high dynamics, precision, and comfort aspects. They guarantee fast, accurate and sensitive compensation.
We offer a wide range for your applications. Our valves are available from the nominal size 25 to size 250mm. We can provide compensation flow up to 70.000L/Min at Δp = 5 bar.
Many options are available to meet your specific requirements.
