Fixed pitch propellers (FPP) by SCHAFFRAN are successfully operated for many decades on various ship types like motor yachts, naval ships patrol boats, governmental vessels, offshore supply vessels, special ships, coasters, passenger liners, and research vessels. As unique as the ships themselves are the propellers designed for these ships and their specifications. They can be designed and manufactured as open or ducted propellers, as single or multiple screw arrangement with 3, 4, 5, 6, or 7 blades.
Apart from meeting the exact power-rpm-relation required, effectiveness (best possible efficiency with minimal fuel use) and low noise (minimisation of vibrations) of the drive as well as harmful cavitation prevention are a priority for us. SCHAFFRAN is often involved in the early design stage of a project and can thereby support the customers in their selection of the right propulsion concept, as well as the fixing of important parameters such as the engine performance and gear box reduction ratio.
