Wärtsilä’s New CPP System
At SMM Wärtsilä introduced its latest development of large Controllable Pitch (CP) Propellers, based on the previously known E-hub type. The new Wärtsilä CP propeller system addresses the demands of medium and large size vessel owners, and is particularly applicable for special vessels that are equipped with dynamic positioning capabilities, as well as vessels having ice notation, the manufacturer said. Among the benefits cited are an increased load capability, the high propulsive efficiency, the reduced fuel consumption that this efficiency brings to the vessel, excellent reliability, and a reduced environmental footprint.
The design follows the systems engineering approach with integration of the propeller and the hub with modern hydraulics and propulsion controls. Computational Fluid Dynamic (CFD) calculations are used to analyze, not only the propeller performance but most importantly also, the interaction between the propeller and hull. This provides extremely accurate information, based on detailed 3-d geometry, for achieving design and parametric optimization. The innovative hub design features forced lubrication and allows the use of environmentally acceptable lubricants (EAL), as required for propulsors operating in US inland and coastal waters. The propeller system is prepared so as to meet the US EPA’s VGP 2013 regulatory requirements. The new design allows for compatible hydraulics and the flushing of lubrication oil.
