9-5. Securing of Unitized Loads of Containers and Single Containers
Size, weight, and stacking characteristics of typical container loads suggest that stowage of' such items be limited
preferably to amidship compartments having good accessibility and insignificant hull contour. Containers can be secured
efficiently by conventional block-stow techniques since the stacking features of the unit load are such that, when tiered,
the loads cannot be offset or staggered but are in alignment one directly above the other.
a. Cluster Bomb Unit, CBU-55/B, Unitized Load of Containers. The CBU-55/B is a typical unit load of containers.
Four individual containers are stacked and unitized to form a load weighing approximately 3,700 pounds and measuring
8 1/2 feet in length, 4 feet in width, and 4 , feet in height. Containers must be aligned vertically to permit stacking.
Hence, to utilize space efficiently and reduce void areas near the hull, the CBU-55/B is best loaded in rectangular
compartments having negligible camber and sheer angles.
(1) Tween-deck stowage. Figure 9-71 illustrates stowage of the CBU-55/B unit load in a typical tween-deck
compartment. In the area illustrated, unitized containers are stacked three high and can be oriented either fore and aft or
athwartships to achieve efficient space utilization. Prior to loading, 1-inch minimum strip decking is laid, and boarding is
positioned on 2-foot centers along the sides of the compartment. Unit loads are positioned fore and aft in the recessed
areas of the hold on either side of the protruding heat bulkhead. Narrow voids can be expected in these areas, and
installation of 4by 4-inch securing structures is required. Unit loads are stowed athwartships along the heat
