Ship engine rooms: machinery sources and hull vibration

Engine-room noise involves both airborne sound and hull vibration; establish the dominant cause before coating the whole space.

Start from machinery status

Record speed, load and the running combination, and distinguish individual machinery operation, combined operation and sailing states. Looseness and friction-type faults are investigated on the equipment first.

What the material addresses

Water-based damping addresses structure-borne vibration of the substrate-and-coating system. Room absorption and the insulation of the enclosing structure still require their own acoustic design.

Confirm the position, then make a sample

Make a sample at the confirmed position and keep records of substrate, batch, application and drying. Areas involving heat dissipation or maintenance must be confirmed by the project lead.

Verify under the same condition

Keep equipment combination, speed, load and measurement points identical, and compare structure-borne vibration and the sound in the room. Noise reduction must be established by measurement for the specific vessel and duty.

Send us the equipment duty, the target panels and the existing coating details, and we will agree the acceptance method.
