Hull Bio-Fouling and Its Treatment

What is Bio-Fouling?

Vessel hulls need protection against the attachment of marine organisms such as barnacles and algae. The presence of these unwanted passengers is known as bio-fouling. Bio-fouling negatively affects the hydrodynamics of the hull by increasing drag and consequently, it requires increases in engine effort to maintain propulsion speed.
