3.3.2 The
Loading Manual is to contain the calculated still water bending moments
and shear forces for the conditions proposed and the maximum permissible
values calculated in accordance with Pt 3, Ch 4 Longitudinal Strength.
3.3.3 The
strengthening of bottom forward derived in accordance with the requirements
of Pt 3, Ch 5, 1 General is to be based
on the minimum draught forward obtained using segregated ballast tanks
only, without recourse to ballasting of cargo tanks.
3.3.4 Where
bottom forward strengthening has not been arranged, at least one ballast
departure and one ballast arrival condition providing for a forward
draught of at least 0,045L is to be included in the Loading
Manual, see also
Pt 3, Ch 5, 1.5 Strengthening of bottom forward.
3.3.5 Where
part-load conditions are proposed with a forward draught less than
that for which the bottom forward arrangements and scantlings have
been approved, the Loading Manual is to provide for the addition of
ballast in segregated ballast tanks only as necessary to attain the
required draught in heavy weather.
3.3.6 Conditions
which provide for wing and centre cargo tanks abreast to be filled,
with adjacent wing and centre cargo tanks empty, should, in general,
be avoided. Similarly, conditions which provide for differential loading
of port and starboard wing cargo tanks with centre cargo tanks empty
should also be avoided. Where such conditions are contemplated, they
will be subject to special consideration which may involve additional
calculation in respect of the resultant effects on transverse strength
and centre tank cross-tie.
3.3.8 Tanks
intended for water ballast are to be indicated in the Loading Manual.
