a. Lighterage. When the HMMWVs are transported by lighterage to or from the vessel, blocking will be

required. When the vehicles are to be transported long distances or through rough waters, tiedowns must be

used.

b. Securing. Requirements for securing HMMWVs aboard general cargo and barge-type vessels are es-

sentially the same. The wheels of the trucks are blocked in front, in rear, and on both sides; the vehicles will be

lashed with wire rope or chains to bulkheads, stanchions, or padeyes. Weld padeyes to the deck if D-ring or

deck tiedown fittings are not available. Figure 6-1 shows typical blocking and tiedown details. The bill and ap-

plication of materials are provided in tables 6-1 and 6-2, respectively.
