 TM 55-1915-200-SDC
5-12. JETTISON SHIP BILL. The jettisoning of topside weights involves time, seamanship, and a subsequent loss of
mission efficiency. Consequently, the jettisoning bill should establish the following:
a.
A sequence which begins with the more easily removed and less vital weights. The bill should specify the
approximate gain in stability from removing each of the weights involved in order to give responsible officers some idea
of the relative importance and results to be attained.
b.
A plan of action and responsibility. To be effective, jettisoning must remove tons (not pounds) of weight
from high levels. The consequent problem of shifting/removing topside weights, cargo, or ballast is of large magnitude,
often covering many hours of backbreaking work to restore seaworthiness to a crippled ship. The speed of gaining some
immediate effect will be enhanced by a plan of action which outlines responsibility for removals, organization of
jettisoning teams, and preparation of tools and methods.
5-13. CREW INDOCTRINATION. All crew members should be educated in the general effects of a "stinger" missile hit
at the waterline or other underwater damage, as will be described in Measures to Safeguard Stability (Section VIII).
Since a single hit may wipe out an entire repair party, ships may have to depend on other than repair parties to confine
flooding and fire, and to perform other emergency functions. More important, ships have been lost because crew
members escaping from damaged areas left doors and hatches open behind them, thus permitting rapid spread of water.
The opposite of this should be impressed on all crew, to confine the flooding, lest stability efforts may be too little and too
late.
a.
Repair parties should be drilled to take action automatically to halt the flooding; to plug, patch, and shore to
eliminate further damage; and to begin immediately the removal of flooding water, giving priority to loose water and high
flooding. Repair parties also should be drilled to make prompt, accurate reports to the damage control center on the
nature of the flooding and the action being taken to combat it.
5-14. MATERIAL PREPARATIONS. There are certain material preparations which are vital in toughening the ship to
resist flooding. They include:
a.
Maintaining the watertight integrity of the ship's subdivision.
b.
Properly classifying closures and fittings.
c.
Properly setting material conditions of closure.
d.
Providing of adequate amounts of well distributed, operable damage control equipment.
