 TM 55-1915-200-SDC
Section IV. DAMAGE RESISTANCE CHARACTERISTICS OF THE LSV
5-8.
a.
Strength.
b.
Watertight integrity.
c.
Stability.
d.
Proper displacement.
e.
Proper distribution of liquids.
f.
Optimum material and personnel readiness.
The maintenance of these features before accidental or battle damage is as important for ultimate survival as
damage control measures after the damage is sustained.
In spite of the inherent resistance of ships and in spite of all precautions that can be made before damage, the
survival of the ship will often depend upon prompt and correct control measures after damage. It is necessary, therefore,
to train the entire ship's company for any eventuality.
a.
Strength. In this ship, the main and hold decks and the shell, with their associated longitudinals, e.g.,
wingwalls, constitute the principal strength members. Together with other decks, bulkheads, and framing, the main deck
and the shell carry the stress imposed on the ship by its weight and the action of the sea. These structural members
resist damage and possess a sufficient margin of safety to permit the ship girder to withstand considerable structural
damage without failure.
b.
Watertight integrity. Watertight subdivision is provided to halt the ingress of water into the ship after
damage and to limit the spread of flooding. Generally, increasing the subdivision greatly enhances a ship's ability to
remain afloat following damage. Whenever flooding occurs at a substantial rate, the ship's life is in jeopardy. Removal
of flood water is futile until ingress is halted or slowed. Hence, watertight integrity with the proper material condition must
be strictly maintained before damage to ensure that any resultant flooding will be localized; this is accomplished in the
following manner.
(1) Transverse bulkheads are arranged to divide the ship into sections so that it can withstand flooding
of one major compartment.
(2)
In order to avoid large heeling moments, longitudinal bulkheads are limited in number to prevent off-
center flooding.
