4.1 The objectives of these Guidelines are to
provide practical guidance to States, ship masters, operators and
owners, shipbuilders, ship repair, dry-docking and recycling facilities,
ship cleaning and maintenance operators, ship designers, classification
societies, anti-fouling paint manufacturers and suppliers and any
other interested parties, on measures to minimize the risk of transferring
invasive aquatic species from ships' biofouling. It is important that
biofouling management procedures be effective as well as environmentally
safe, practical, designed to minimize costs and delays to the ship,
and based upon these Guidelines whenever possible.
4.2 To minimize the transfer of invasive aquatic
species, a ship should implement biofouling management practices,
including the use of anti-fouling systems and other operational management
practices to reduce the development of biofouling. The intent of such
practices is to keep the ship's submerged surfaces, and internal seawater
cooling systems, as free of biofouling as practical. A ship following
this guidance and minimizing macrofouling would have a reduced potential
for transferring invasive aquatic species via biofouling.
4.3 The management measures outlined within these
Guidelines are intended to complement current maintenance practices
carried out within the industry.
