Designed as a tension compensator for offshore floating drilling vessels when the drill pipe or casing is latched to the well or for operations requiring minimum motion.
This passive line compensation system mitigates the risk of lockup of the primary heave compensation system. When a lockup occurs, the DSC automatically activates and takes overcompensation.
Features
- Nitrogen gas for APVs.Single lift for installation.
- Tension variation ± 5% (at one-meter heave and 10 second periods).
- Remote cylinder locking.
