4.1 The information listed in section 3 should
be repeated in the damage control booklet.
4.2 The damage control booklet should include
general instructions for controlling the effects of damage, such as:
-
.1 immediately closing all watertight and weathertight
closing appliances;
-
.2 establishing the locations and safety of persons
on board, sounding tanks and compartments to ascertain the extent
of damage and repeated soundings to determine rates of flooding; and
-
.3 cautionary advice regarding the cause of any
list and of liquid transfer operations to lessen list or trim, and
the resulting effects of creating additional free surfaces and of
initiating pumping operations to control the ingress of water.
4.3 The booklet should contain additional details
to the information shown on the damage control plan, such as the locations
of flooding detection systems, sounding devices, tank vents and overflows
which do not extend above the weather deck, pump capacities, piping
diagrams, instructions for operating cross-flooding systems, means
of accessing and escaping from watertight compartments below the bulkhead
deck for use by damage control parties, and alerting ship management
and other organizations to stand by and to co-ordinate assistance,
if required.
4.4 If applicable to the ship, locations of non-watertight
openings with non-automatic closing devices through which progressive
flooding might occur should be indicated as well as guidance on the
possibility of non-structural bulkheads and doors or other obstructions
retarding the flow of entering seawater to cause at least temporary
conditions of unsymmetrical flooding.
4.5 If the results of the subdivision and damage
stability analyses are included, additional guidance should be provided
to ensure that the ship's officers referring to that information are
aware that the results are included only to assist them in estimating
the ship's relative survivability.
4.6 The guidance should identify criteria on which
the analyses were based and clearly indicate that the initial conditions
of the ship's loading extents and locations of damage, permeabilities,
assumed for the analyses may have no correlation with the actual damaged
condition of the ship.
