Trolling | Dynamic Positioning

Precise and safe positioning

The Prop.act makes it possible to steplessly vary the propeller rotation at constant engine speed and, vary the thrust via the control lever. The unit is confi gured for continuous operation and as such can be used for dynamic positioning.

System solution

Self-sufficient and ready-to-install

The Prop.act is a self-sufficient clutch system which comprises of an operationally ready clutch unit and the Prop.act control system. The unit can be freely positioned in the drive train and is mounted on the floor of the vessel. The engine and rudder propeller can be connected using drive shafts, for example. The Prop.act control system is connected to the ship‘s control. The supplied cooling system is integrated in the ship‘s cooling circuit. Free accessibility of the Prop.act facilitates ideal service conditions with a self-sufficient oil circuit, which is adapted optimally to the clutch system.

Firefighting

Pinpoint accuracy in any situation

The Prop.act HD is primarily used for applications with firefighting systems. Here, the firefighting pump can be operated by the main diesel engine while the drive remains active to hold the position at low propeller rotation.
