For the shipping market RENK manufacture gear units for merchant and supply vessels, LPG/LNG tankers and ferries. These include single and double marine gearboxes, as well as their more special shaft tunnel gear units to meet the needs of all customers and applications.



For propeller shaft disconnection, RENK has developed the automated PSC – Propeller Shaft Clutch, as well as the manual KAZ. Disconnecting the propeller allows the use of the main engine to power a generator when standstill operations demand a large amount of electrical power. – In a twin-screw vessel, disconnecting one of the main engines allows the idling propeller to windmill in order to reduce drag and thereby the fuel consumption. – In a single-screw vessel, disconnecting the main engine in case of a ME break down, allows for a power take home solution if a shaft generator/motor is present. – Allows for engine maintenance during sea operation.
