Manufacturing of propeller blades

Manufacturing of new propeller blades are done with regards to the special welding procedures that have been established by the classification societies.

We offer propeller overhaul after installation to make sure that the propeller blades run efficiently.

Manufacturing of new tips

When manufacturing new tips, the damaged sections of the blades are cut off and samples for analysis of the material are taken. The new tips are casted to be welded onto the blades.

Depending on the material, the blades are then heat-treated to normalise the material after the welding.

Maintaining full efficiency of the blades

To obtain full efficiency of the blades and lower fuel consumption, we polish the blades in several steps to obtain the original smooth surface.

If possible, straightening of the blades is also an option. The blades are then adjusted back into original shape using heat or cold straightening.
