Propeller

Propeller

The propeller is made in a unique combination of two printing materials which provide both strength and durability. The use of 3D printing allows us to continuously update the hydrodynamic profile and offer improved versions of the propeller to our customers. Optimization of the hydrodynamic propeller profile is extremely important, and even the smallest changes affect efficiency.

Hours have been spent on improving fine details. For example, the trailing edge transition point - the point where the asymmetrical blades connect to the rim - has been optimized to provide high efficiency at low rpm, but also to enable high thrust at full rpm without cavitation.

Propeller types

We offer two standard types of propeller depending on the requirements of your subsea operation. The series of propeller consists of an asymmetric propeller and a symmetric propeller.

 

The two types of propellers are available for both VM and VL. Independent of thruster size, we are able to configure the propeller to best serve your specific operation requirements.

Asymmetric

 The asymmetric propeller is superior in subsea operations which require that the thruster is extra efficient in one direction.  

 

In order to possess this functionality, the asymmetric propeller is provided with an hydrodynamic optimized asymmetric blade profile.

The asymmetric propeller achieves full thrust potential paired with an asymmetric configuration of inlet and outlet rings.
 

Symmetric

 The symmetric propeller is superior in subsea operations which require that the thruster is equally efficient in both directions. 

In order to possess this functionality, the symmetric propeller is provided with a symmetric blade profile.

The symmetric propeller achieves full thrust potential paired with a symmetric configuration of inlet and outlet rings.
