Part B, Section 1.B
B. Parties shall endeavour to
ensure that ships
flying their flag or operating
under their authority
which may conduct ballast water
exchange:
.1 are fitted as needed, with
a loading instrument to
perform calculations of shear
forces and bending
moments induced by ballast water
exchange at sea and
to compare with the permissible
strength limits;
.2 undertake (a)n evaluation
of the safety margins
for stability and strength contained
in allowable
seagoing conditions specified
in the approved trim
and stability booklet and the
loading manual,
relevant to individual types
of ships and loading
conditions. In this regard particular
account should
be taken of the following requirements
:
.1 stability to be maintained
at all times to values
not less than those recommended
by the Organization
(or required by the Administration);
.2 longitudinal stress values
not to exceed those
permitted by the ship's classification
society with
regard to prevailing sea conditions;
and
.3 exchange of ballast in tanks
or holds where
significant structural loads
may be generated by
sloshing action in the partially
filled tank or hold
to be carried out in favourable
sea and swell
conditions so that the risk of
structural damage is
minimized.
