3.1 When designing and constructing a ship that
will operate with ballast water exchange the following considerations
should be taken into account:
-
.1 maximizing the efficiency of ballast water
exchange;
-
.2 increasing the range of sea conditions under
which ballast water exchange may be conducted safely;
-
.3 shortening the time to complete ballast water
exchange (thereby increasing the types of voyages under which ballast
water exchange can be undertaken safely); and
-
.4 minimizing the accumulation of sediments (refer
to Guidelines on design and construction to facilitate sediment control
on ships (G12)).
