Biofouling will cause daily damage to the hull, affecting the hydrodynamic effects of the ship. The engine of the ship must increase the load operation to offset its impact and cause more carbon emissions. The solution on the market is to paint the hull. Adding toxic ingredients to kill aquatic organisms, these substances will eventually flow into the marine ecology and harm the environment. The research team at Kiel University in Germany and the university-derived company Phi-Stone have developed an environmentally friendly vessel coating that prevents aquatic crustaceans/microorganisms from easily attaching to the surface of the vessel, while being non-toxic does not endanger the marine ecology.

This environmentally friendly boat coating is based on a "polythiourethane (PTU)" component polymer compound and specially prepared ceramic polymer particles that give the coating a layer of incredible smoothness. Aquatic organisms are unable to form permanent communities on their surface, which can effectively avoid biofouling and siltation. They only need routine cleaning and maintenance to allow aquatic crustaceans/microorganisms to fall off their paint. This technology has been used for practical testing, and it has been applied to ships in Central and Africa and to Belgium, and no biofouling has been formed for two years.
