Sustainable propulsion from tailor-made blade design for optimum propeller efficiency with low vibration and noise levels
Brunvoll aim to be a strong contributor to a sustainable shipping industry by providing systems designed for efficient operation.
Brunvoll serves a large variety of vessel applications. There is a continious demand for propeller designs to be optimised in order to achieve the highest energy efficiency. All Brunvoll CP- and FP-propeller configurations are designed for the individual ship.
A ducted propeller gives up to 30% higher thrust at low speed compared to an open propeller.
Feathering is an option on standard CP-propeller systems. On a feathering propeller the blade angle can be arranged in line with the water flow.
This reduces the water resistance and gives the following advantages;
With twin screw installation and one side out of operation it is possible to reduce requirements for the shaft brake with CP-propeller.
