Prevent Biofouling on Ship Hulls with the Ecohull

Prevent biofouling and reduce the use of antifouling paint with the Ecohull.

Ecohull brochure

How it Works

The LG Sonic Ecohull has been especially designed to prevent the growth of biofilm on ship hulls. The products can be mounted on the inside of the hull structure to transmit ultrasound through the material into the water.

Biofilm Control

Biofilm formation starts by bacteria attaching to a surface. The ultrasonic sound waves of LG Sonic create resonance around the solid surfaces within the water, thereby preventing bacteria to adhere to a surface. EPS, present in an existing biofilm, is directly targeted, degrading the biofilm.

Antifouling Reduction

When bacteria, algae and biofilm are reduced, as a result, the antifouling measures can also be reduced. The disadvantage of using these coatings is that it they can either be harmful for the environment, expensive and/or ineffective.

Safe Solution

The use of the LG Sonic Antifouling products is chemical free, safe for fish and other marine organisms and is in line with the ASC standards for marine use of ultrasonic devices.

Biofouling Prevention Benefits

Ultrasonic Algae Control Benefits

Effective biofilm control

Reduces fouling by up to 80% on the hull and prevents the growth of new biofilm.

Ultrasonic Algae Control Benefits

Decrease dry-docking intervals

Because of the continual protection the hull remains clean with no need for dry-docking.

Ultrasonic Algae Control Benefits

Safe for the marine ecosystem

Ultrasound effectively prevents biofouling without the use of harmful chemicals and without harming the marine ecosystem

Ultrasonic Algae Control Benefits

Improves fuel economy

By preventing the biofilm from growing a remarkable reduction in fuel of consumption is achieved.

Ultrasonic Algae Control Benefits

Easy installation

Due to our marine grade design mounting footprint technology it is very easy to install the system.

Ultrasonic Algae Control Benefits

Prevent damage anticorrosion layer

Avoid damage to industrial systems such as to filters. The anticorrosion layers will be preserved.
