7.1 It is recognized that in actual damage scenarios,
where the cargo density exceeds the seawater density, all or most
of the cargo may be lost in the event of bottom damage. However, for
the purposes of these calculations, even in cases where the nominal
cargo oil density as calculated in paragraph 4.4 exceeds the density
of seawater, the cargo level and remaining oil after damage should
still be calculated based on hydrostatic pressure balance in accordance
with paragraph 7.3.2.
