Grenaa Motorfabrik has more than 100 years of experience in propeller manufacture. We specialise in plants for professional workboats and passenger ships. Within this segment we continuously strive to improve our products and services. Our range includes CP-propeller systems between 200 and 2.000 HP in diameters between 1.000 and 3.000 mm.
 
A matching power train is the key to fuel savings
Grenaa propeller projects are based upon computer calculations of the performance. From a wide range of efficient blade designs and based upon the performance characteristics of engine and propeller we make the perfect propeller match for each ship. This careful design engineering work ensures a low fuel consumption throughout the lifetime of the ship.
 
Detailed engineering expertise in the complete power train ensures our clients a total consulting service at the project stage. All plants are computer model calculated to ensure optimum performance and they are analyzed against harmful torsional vibrations. This ensures a trouble free system design.
 
Reliability and serviceability
Grenaa propellers are engineered to ensure the lowest wear rates and longest service life. Additionally, the systems are designed with allowance for reconditioning to as-new standard once wear does become present.. In case of emergency we have a large stock of spare parts including propeller blades and a service organisation which responds swiftly giving minimum down-time.
