Insulating bow thruster

What is the problem? Boegschroef isoleren
The bow thruster has a very typical noise problem. The sound has a metallic and crackling sound. Even though the bow thruster is not used much, the noise level is often considerable and can be reduced both outside and inside the ship.

What is the solution?
Make the ship's hull on the inside of the hull free of rust, grease and dirt (paint can remain). Then apply at least one and a half meters around the bow thruster Vibradamp A-90-P two-component paste in a thickness of +/- 1 mm. Press into the paste Zincor steel plates with a gap of 10 mm between each plate. Also insulate the tunnel in this way. This way of insulating is called Sandwich anti-drumming, the best way of resonance isolation on a ship's hull above 3 mm steel.

You apply Vibradamp in the ratio 1:1:4. This means 1mm paste, 1mm Zincor on 4mm steel. More solutions can be found on our Tips page.

Which products do I use and where?
Vibradamp A-90-P in combination with Zincor steel plates on a ship's hull of 4 mm or more.
Vibraflex Extreme on a steel ship's hull up to 3 mm.
Isomat TS14 on a polyester ship hull.

Tip
If you are going to conceal the bow thruster inside furniture, then fill cavities with Akotherm, this reduces sound formation and also provides excellent thermal insulation!
