7-11. SHORING BULKHEADS. Most shoring of bulkheads is done to support bulkheads which are endangered by
structural damage or weakness caused by the pressure of flooding water. Methods of shoring bulkheads are shown in
FIGURES 7-6, 7-7, and 7-8. Observe the following when shoring bulkheads:
a. Allow a large margin of safety in number of shores used.
b. Spread pressure. Make full use of strength members by anchoring shores against beams, stringers, frames,
stiffeners, and stanchions. Place legs of shoring against strongback at an angle of 45 degrees or 90 degrees if at all
possible.
c. Do not attempt to force a warped, sprung, or bulged bulkhead back into place. Place shoring so that it will hold
bulkhead in its warped or bulged position.
d. Strengthen main shores, when possible, with auxiliary shores, as shown in FIGURE 7-8. Notice that strength
members A, B, C, and D have been locked in place with auxiliary shores E and F to keep them from jumping out as the
ship works in the seaway. Cleats H and J hold E in place.
