RECOMMENDATION ON A STANDARD METHOD FOR
ESTABLISHING COMPLIANCE WITH THE REQUIREMENTS FOR CROSS-FLOODING
ARRANGEMENTS IN PASSENGER SHIPSIn order to ensure uniform application
of Regulation 7(e) of Chapter II of the International Convention for the
Safety of Life at Sea and/or Regulation 5(c) of the Regulations on
Subdivision and Stability of Passenger Ships (Resolution A.265(VIII)),
Administrations are recommended to apply the following cross-flooding
formulae:
The following parameters, in feet or
metric units, are used in formulae (I)-(III):
W = volume
of water entering the equalizing compartments during the considered period,
S = cross-section area through the cross-flooding
duct,
H
o = head of water before commencement of
cross-flooding,
H
θ= head of water at the time
of cross-flooding where the vessel is heeled θ, (or at the angle of margin
line immersion),
h
f = final head of water after
cross-flooding ( h
f = 0 when the level inside the equalizing
compartment is equal to the free level of the sea),
For guidance some typical values for k
are given in Figures 2-12.
