The total required capacity of the water supply should satisfy
SOLAS regulations II-2/19.3.1.2 and II-2/19.3.1.3 (if applicable), simultaneously calculated for the largest
designated cargo space. The capacity requirement for SOLAS regulation II-2/19.3.1.2 should be met
by the total capacity of the main fire pump(s) not including the capacity
of the emergency fire pump, if fitted. If a drencher system is used
to satisfy SOLAS regulation II-2/19.3.1.3,
then the drencher pump should also be taken into account in this total
capacity calculation.
