Figure 7-24. Partial encasement of air vent.
(2) When block-stowage methods are employed, compartment obstructions, such as ladders or stanchions,
are not partially encased before emplacement of the unit loads. Instead, the cargo is stowed in block form around the
obstruction and shored at a later time in the operation. An example of block-stow shoring of a ladder and stanchion near
the hull is illustrated in figure 7-25. In actual practice, stowage of additional unit loads would continue before installation
of shoring to achieve maximum stowage rates. Notice that neither the ladder nor the stanchion bear any cargo loading
that might result from ship motions. Instead, all forces are transmitted to the ship's structures through the 4by 4-inch
kickers. It should be emphasized that ship's structures, regardless of appearance, might not be structurally adequate for
support of cargo loads. All stanchions and posts should be examined carefully and protected with full-block shoring, if
necessary. In no case, however, should access ladders bear cargo loads of any type. Ladders are not intended as
loadbearing structures, and failure under load could result in serious degradation of the stow.
