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 all 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.
