Tunnel Thruster - Type SuperSilent

The Super Silent (SS) tunnel thruster has a modified hydraulic power pack for low noise. It has double walls through the full tunnel length and a flexibly mounted inner tunnel. This concept provides noise reduction up to 10 dB compared to standard designs.

A reduction up to 25 dB can be reached in combination with floating floors and other measures by the shipbuilder.
