Wärtsilä Controllable Pitch (WCP) propeller systems provide excellent performance and manoeuvrability, and are recommended for vessels with frequent sailing routes that involve multiple operating conditions. These can be, for example, vessels requiring full power in both bollard pull and freesailing conditions, or that make frequent port calls. WCP propeller systems can also be applicable for vessels that encounter varying weather conditions or demanding operational requirements such as dynamic positioning. A controllable pitch propeller is often the optimal choice for installations with a shaft generator operating at constant rotational speed. Full propulsion power is available in both heavy and light conditions through an automatic pitch adjustment. Engine overload is avoided regardless of the conditions.
The WCP propeller system is the ideal choice for diesel-mechanic propulsion with both medium-speed and low-speed diesel engines. By integrating a suitable gearbox and Power Take Off/In, the WCP propeller system can be transformed into a hybrid propulsion system that enables:
- High operational efficiency and flexibility
- A power boost mode
- Emergency propulsion power.
A Wärtsilä Controllable Pitch (WCP) propeller system is a fully customized combination of a hub, propeller blades, shafting, hydraulics and a control system, as well as any further accessories needed to meet the customer’s needs. Wärtsilä’s hydrodynamic experts tailor the propeller for each application to achieve the optimum balance between fuel consumption and comfort levels as set by the customer.
