6.9 Ship maintenance and recycling facilities
should adopt measures (consistent with applicable national and local
laws and regulations) to ensure that viable biofouling organisms or
chemical and physical pollutants are not released into the local aquatic
environment. These measures include the following:
-
.1 capturing biological material to minimize the
risk of organism survival and establishment and other impacts of biological
material being released into the aquatic environment;
-
.2 treating and/or disposing of captured biological
material in an environmentally appropriate manner;
-
.3 scheduling of ships' arrival and departure
at cleaning and maintenance facilities and at locations where ships
are moored while waiting for cleaning and maintenance to minimize
the risk of fouled ships contaminating other ships and the surrounding
environment;
-
.4 removing biofouling from all underwater surfaces
of a ship when in dry-dock, including niche areas; and
-
.5 lowering or extending retractable equipment
such as stabilizers, thrusters, transducers and similar when a ship
is in dry-dock or slipped, to permit access for the removal of biofouling
from the equipment and its housing.
