Wärtsilä Introduces New Propellers to Reduce Bunker Consumption
Wärtsilä Corp. (Wärtsilä) says it is introducing a controllable pitch (CP) propeller system designed for increased fuel efficiency.
The new propeller system is targeted at medium to large vessels, particularly special vessels with dynamic positioning capabilities or ice notation.
The CP system integrates the propeller and hub with modern hydraulics and propulsion controls, increasing load capability, propulsive efficiency, and reliability.
Computational fluid dynamic (CFD) calculations provide data about the propeller performance and interactions between propeller and hull, allowing for each Wärtsilä CP propeller to be individually customized for specific requirements.
The hub design uses forced lubrication and allows for the use of environmentally acceptable lubricants (EAL) as required in U.S. inland and coastal waters.
"The WCP propeller system is the result of the work of highly experienced design engineers in our European R&D headquarters having access to the very latest and most sophisticated software and analysis tools," said Wim Knoester, director of Propulsion Sales for Wärtsilä Ship Power.
The system can also be easily integrated with new Wärtsilä propulsion control systems and bridge architecture.
Industry players say ship owners are increasingly interested in fuel-saving measures like more efficient propellers as methods of improving their competitiveness.
