SECTION III — ASSUMED VOLUMETRIC HEELING MOMENT OF FEEDERS AND TRUNKS

(A)        SUITABLY PLACED WING FEEDERS (See Figure 5)

It may be assumed that under the influence of ship motion underdeck voids will be substantially filled by the flow of grain from a pair of longitudinal feeders provided that—

(a)        the feeders extend for the full length of the deck and that the perforations therein are adequately spaced;

(b)        the volume of each feeder is equal to the volume of the underdeck void outboard of the hatchside girder and its continuation.

(B)        TRUNKS SITUATED OVER MAIN HATCHWAYS

After the assumed shift of grain the final void pattern shall be as shown in Figure 6.

Note on Figure 6:

If the wing spaces in way of the trunk cannot be properly trimmed in accordance with Regulation 3 of this Chapter it shall be assumed that a 25 degree surface shift takes place.
