Fixed pitch propellers


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.

Especially the planning, monitoring, and analysis of ship model and sea trial together with the evaluation and optimisation of the drive line is made use of by many customers. During the propeller design all parameters of the ship and the drive line are taken into account in order to have the optimal combination of propeller diameter, number of blades, blade area, section profile, and blade contour by adapting it to the wake field. We rely on decades of experience and latest FEA and CFD methods. Due to our stringent quality assurance, a measurement system, especially designed by SCHAFFRAN and specialist personnel, we are capable of manufacturing propellers according to customer specification in the required tolerance class ISO 484-1981:2015 class "S", class "I", or class "II".

All products are designed to match the requested classification rules, e.g. ABS, BV, DNV, LRS, RINA.

Classification survey can be conducted on demand and the matching classification approval certificate can be delivered.

We are happy to consult you in the course of your project planning and to answer your questions and give you an economically viable quotation.
