Propeller System Applications

Helseth is a highly specialized propeller manufacturer, operating in modern facilities close to Molde in north-western Norway. Since the first Helseth propulsion system was installed in a fishing boat in 1912, our company has gained a profound knowledge of how to produce long-lasting propulsion systems. Today we serve a wide variety of small and medium-sized professional vessels such as cargo and passenger vessels, ferries, tankers, work boats, high-speed vessels, fishing vessels and offshore vessels. Helseth is a part of the Kumera Helseth - Marine Division of Kumera Corporation.

The core design and manufacturing programme comprises adjustable pitch and controllable pitch propellers with diameters of up to 4400 mm, and up to 4500 kW engine power. Shafts and stern tubes are normally part of the supply. We are also able to deliver complete propulsion packages including reduction gears and control systems.

Helseth designers and engineers are continuously involved in R&D projects to maintain our position as a leader in the field of propeller system design.

Mechanical design

We use both 2D and 3D CAD tools for the design and modelling of our propeller systems. The three-dimensional visualization and animation capability of the design process ensures precision, and eliminates assembly problems in new systems.

Stress-analysis of Highly Loaded Components

3- dimensional CAD modelling facilitates the stress-analysis of our propeller systems. This analysis is done using the FE software, Ansys, to eliminate stress and fatigue problems in new designs. The use of FEA helps us reducing propeller weight without compromising on strength and lifetime.

Hydrodynamics

All propeller blades are tailor-made for each project in order to give the optimum propeller for each and every ship. Propeller blade design is based on leading computer software, and perfected by Helseth’s long experience in manufacturing propellers.
