Shaft Disconnecting Devices
RENK’s Propeller Shaft Disconnecting Devices are engineered to provide reliable and efficient methods for connecting and disconnecting the 2-stroke engine from the propeller. In a twin-screw vessel this allows for windmilling of one propeller while the vessel is operating on one engine, thus reducing the propeller drag and increasing fuel efficiency. In a single screw vessel, disconnecting the shaft in case of engine failure allows for safe-to-port (PTH) mode by the use of a shaft generator.
Through the KAZ and PSC, RENK offers manual, semiautomatic and fully automatic engagement and disengagement mechanisms, each designed to cater to specific operational needs and requirements:
Manual Engagement/Disengagement:
The KAZ allows for manual engagement/disengagement of the main engine from the propeller by removing the spacer ring.

The KAZ is ideal for applications where operator requires propulsion redundancy and a simple, reliable and manual disconnection device is sufficient. This includes but is not limited to smaller or more traditional vessel systems where automation is not a primary requirement.
Automatic Disengagement/Semiautomatic engagement:
The semiautomatic Propeller Shaft Clutch (PSC) allows for an automatic (push-of -a-button) shaft disconnection, while connection requires a person to be present in the engine room. In this configuration, the connection and disengagement of the engine and propeller are hydraulically actuated. This option combines manual operation with automated efficiency, providing a balance between ease of use and operational flexibility.
Fully Automatic Disengagement and engagement:
The fully automatic propeller shaft clutch (PSC) offers fully automatic engagement/disengagement, allowing for complete hydraulic control from the bridge/control room. This option provides seamless, hands-off operation and is ideal for vessels requiring higher levels of automation, improving convenience and safety for operators by reducing manual intervention.
Whether it is for routine operations or emergency disengagement, RENK’s shaft disconnection devices provide the necessary flexibility to meet the specific needs of modern marine vessels, ensuring continuous, effective operation in various marine environments.
