Bottom paint is the new bottom line.
Once a surface, such as a ship’s hull, enters a marine environment, it is traditionally rapidly colonized by a range of species. In addition to transporting invasive species, biofouling negatively impacts air quality and fuel efficiency by increasing a ship’s resistance in the water. A ship with a heavy coating of slime can require up to 38% more energy to maintain speed than a vessel with a clean hull.
Any surface submerged in seawater is subject to marine organisms, including hundreds of thousands of types of bacteria, algae and molluscs. Within the shipping industry, these marine organisms are often known as fouling or biofouling. The accumulation of organic material on a surface can have serious impacts on the shipping industry.
These impacts include increased vessel fuel consumption, Green House Gas (GHG) emissions, and loss of manoeuvrability due to the deterioration of their underwater hulls. Hull deterioration occurs through coating degradation, bio-corrosion and an increase in hull roughness.
