Helseth Propeller systems

Helseth product portfolio is made up of 3- and 4-bladed propellers designed with the help of modern tailor-made computer programs, and manufactured in 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 Helseth we have a daily based contact with all the important class societies to ensure the best result for our customers.

High speed propulsion systems

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