The new Passive Heave Compensation Winch system, a set of winches engineered to safely provide constant tension through the rated range of motion, is primarily used in subsea drilling and completion activity, but applicable to any environment where a load experiences resistance to movement due to hydrodynamic drag (ROVs, PLETs, etc.). Far less complex than an active compensation system, the winch is electrically powered and uses a custom-built Hydraulic Power Unit and control set to monitor winch status and activity.
