4.1 With regard to loading conditions to be submitted
to the Administration (exclusive of the loading conditions contained
in loading and stability manual) the principal objective, at the stage
of design evaluation, is that the Administration can satisfy itself
that the calculations presented will cover all conditions of full
and partial loading, including variations of either draught and trim.
To achieve this objective the Administration may either:
-
.1 require a complete analysis of survival requirements
over the full range of probable loading conditions; or
-
.2 undertake approval on the basis of service
conditions proposed by the builder or owner, in which case the Certificate
of Fitness should be endorsed for the conditions accepted.
4.2 Particular attention should be paid to the
provision of adequate stability data to enable the master to take
into account accurately the effect of liquid heeling moments of the
contents of undamaged tanks. These heeling moments vary with the specific
gravity of the liquid and the percentage filling of the tanks and
may change significantly in magnitude from condition to condition.
Adequate information would include curves showing the variation of
liquid heeling moment with the contents of each individual tank.
4.3 In addition to the usual loading information
required under intact stability requirements the master should be
supplied with the following information pertaining to damage stability.
-
.1 data relative to loading and distribution of
cargo and ballast necessary to ensure compliance with damage survival
requirements;
-
.2 data relative to the ship's survival capabilities;
-
.3 a damage control drawing showing the position
of important fittings and listing instructions for their control;
-
.4 data relating to the effect of free surface
or liquid heeling moments of cargo tanks at all stages of filling;
-
.5 example calculations and standard blank forms
to facilitate calculations.
4.4 The following should be stated on the Certificate
of Fitness:
-
.1 the deepest draught or least freeboard permitted
for those loading conditions which require greater freeboard than
the International Load Line Certificate (1966);
-
.2 the range of specific gravities of cargoes
which may be carried, this relates to all cargoes;
-
.3 the particular cargo tanks in which certain
ranges of specific gravities of cargoes may be carried, if relevant;
-
.4 details of fittings, valves etc., the control
of which is essential for survival, together with instructions for
control, operation and logging; and
-
.5 identification of required loading and stability
manual.
