A Clutch Solution For A Ferry

A robust clutch solution for use on roll-on/roll-off (RORO) vessel gearboxes was needed by a major Chinese manufacturer of marine propulsion systems. The ship transports passengers travel on an upper deck and wheeled cargo/vehicles in a lower enclosed deck.

The large ferry utilizes dual diesel-powered propeller shaft propulsion. Each of the two propulsion shaft drivetrains features twin diesel engines connected to a common gearbox. Clutches are installed on both gearbox input shafts to allow engagement/disengagement of either engine, as needed.

The OEM investigated clutch designs from several manufacturers. Ultimately, KMS clutches from Stromag were selected based on reputation, responsiveness, quality, and cost-effectiveness. Stromag supplied Model KMS 18000/25 clutches which were integrated and adapted into the gearboxes. Each 635 mm diameter clutch has a torque rating of 240,000 Nm.

Wet-running, multi-disc KMS clutches are specifically designed for marine gearbox applications. The oil-cooled, hydraulically-operated units are used where high torques must be transmitted reliably in tight engine room spaces. The clutches have an excellent torque-to-weight ratio and low mass moment of inertia. Units feature a high thermal capacity since switching heat is dissipated by internal oil cooling. All KMS models are low maintenance, as any disc wear is automatically compensated by piston travel.
