14.1 For the purpose of reducing the heeling moment
a saucer may be used in place of a longitudinal division in way of
a hatch opening only in a filled, trimmed, compartment as defined
in A 2.2, except in the case of
linseed and other seeds having similar properties, where a saucer
may not be substituted for a longitudinal division. If a longitudinal
division is provided, it shall meet the requirements of A 10.9.
14.2 The depth of the saucer, measured from the
bottom of the saucer to the deck line, shall be as follows:
-
.1 For ships with a moulded breadth of up to 9.1
m, not less than 1.2 m.
-
.2 For ships with a moulded breadth of 18.3 m
or more, not less than 1.8 m.
-
.3 For ships with a moulded breadth between 9.1
m and 18.3 m, the minimum depth of the saucer shall be calculated
by interpolation.
14.3 The top (mouth) of the saucer shall be formed
by the underdeck structure in way of the hatchway, i.e. hatch side
girders or coamings and hatch end beams. The saucer and hatchway above
shall be completely filled with bagged grain or other suitable cargo
laid down on a separation cloth or its equivalent and stowed tightly
against adjacent structure so as to have a bearing contact with such
structure to a depth equal to or greater than one half of the depth
specified in A 14.2. If hull structure to provide such bearing surface
is not available, the saucer shall be fixed in position by steel wire
rope, chain, or double steel strapping as specified in A 17.1.4 and spaced not more than 2.4
m apart.
