Built-UP Propellers

Built-up propellers are an attractive alternative for monobloc fixed pitch propellers
Underwater propeller blade installation and replacement allows uninterrupted vessel service (no dry-docking)
Reduced operating costs thanks to the highly efficient hydrodynamically optimised propeller blades
Streamlined hub design with minimised hub diameterpropeller diameter ratio
Easy transport and handling
Built-up propellers can be supplied in Bronze or Stainless Steel
The Wärtsilä OPTI Design propeller methodology takes into consideration the full-scale interaction between the propeller and hull, thereby ensuring optimised efficiency
