6.1 Anti-fouling systems and operational practices
are the primary means of biofouling prevention and control for existing
ships' submerged surfaces, including the hull and niche areas. An
anti-fouling system can be a coating system applied to exposed surfaces,
biofouling resistant materials used for piping and other unpainted
components, marine growth prevention systems (MGPSs) for sea chests
and internal seawater cooling systems, or other innovative measures
to control biofouling.
6.2 The anti-fouling system used should comply
with the AFS Convention, where necessary.
