The product portfolio of Kumera Marine AS in Hjelseth  is made up of 3- and 4-bladed propellers designed with the help of modern tailor-made computer programs, and manufactured of high quality materials.

All propeller blades are tailor-made for each vessel and designed by the use of modern design software and experienced designers to fit the vessel perfectly. The propeller hub and pitch-control mechanisms are designed by use of extensive FEM-analysis tools to ensure low weights and sufficient strengths to survive the most hazardous environments.

At Kumera Marine AS in Hjelseth we have a daily based contact with all the important classification societies to ensure the best result for our customers.

High speed propulsion systems

For High Speed Vessels – normally operating at above 25 knots speed – hydrodynamics become much more important for the optimization of the propulsion solution. In addition to the propeller design also the design of brackets, rudders and propeller tunnel has to be optimized. Due to interaction with the hull design, we work closely with the vessel designer on most high speed applications to ensure the most efficient solution.
