Biofouling Management
40% reduction of fuel efficiency
CO2 emission
Ecosystem disruption
If organisms such as barnacles, oysters, and sea squirts are attached to the surface of a ship, frictional resistance against the water increases when the ship moves, reducing the speed of the ship.
Fuel efficiency is reduced by up to 40% due to organisms attached to the hull, and when converted into monetary value, the damage amounts to 100 billion dollars (approximately 110 Bn USD) worldwide every year.
EXISTING SOLUTION
"Human Intensive Work"
Underwater removal method
A diver works directly to the surface of the ship and removes it using a brush. High risk of human casualties and is expensive and time-consuming.
Chemical removal method
Applying toxic chemical contained antifouling paint. Ocean contamination issues.
The biofouling starts with biofilms. Once a biofilm is created on the surface of a vessel, marine organisms recognize it as a food source and attach themselves to it. recognize it as a food source and attach themselves to the ship's surface.
To solve this problem, bioelectric technology was developed, which involves applying a special conductive material to the surface of the ship.
This technique inhibits the initial formation of the biofilm, making it impossible for adherent organisms to attach to cannot attach. The biggest advantage of the technology is that it is environmentally friendly, as it does not use harmful chemicals, but it is also economical, as it does not require constant underwater cleaning or paint application.

Innovation of antifouling System
Bioelectric technology inhibits biofilm and biofouling formation on the surface of vessel.
The heart of the marine debris problem starts with biofilms. Once a biofilm is created on the surface of a vessel, marine organisms recognize it as a food source and attach themselves to it. recognize it as a food source and attach themselves to the ship's surface.
To solve this problem, Tromatz technology was developed, which involves applying a special conductive material to the surface of the ship.
This technique inhibits the initial formation of the biofilm, making it impossible for adherent organisms to attach to cannot attach. The biggest advantage of Tromatz technology is that it is environmentally friendly, as it does not use harmful chemicals, but it is also economical, as it does not require constant underwater cleaning or paint application.
What's more, it's a preventative approach that stops the problem before it starts, so you can address the issue of adherent organisms at the source.
