The longer a ship goes without having a hull clean, the greater the fuel consumption.
The build up of biofouling on a ships hull increases drag, which in turn causes the ship to burn more fuel. Studies have shown that the build up of biofouling after just one year causes a 15% increase in fuel costs. After five years build up, the fuel costs rise by as much as 40%.
While any hull clean will remove the habitat for an invasive species and reduce the potential for them to reach reproductive maturity, only Envirocart™ has a unique complete capture, containment and filtration system to prevent the catastrophe that can occur when biofouling is leaked back into the water.
In the past, biofouling was removed using abrasive wire brushes and high pressure water blasting. While these methods work, they come with consequences. These aggressive techniques damage the anti-fouling, which causes the toxic biocides contained in the paint to be released into the water. It also damages the softer biocide-free paints, reducing their effectiveness.
In contrast, the blades of the Envirocart glide over the surface of the hull, so the antifoul paint is not only undamaged but invigorated and instead of being washed int the water, the biofouling is captured and contained.
