Dead craft condition for the purpose of paragraph 9.1.5
should be understood to mean a condition under which the main propulsion
plant and auxiliaries are not in operation and, in restoring the propulsion,
no stored energy is assumed to be available for starting and operating
the propulsion plant, the main source of electrical power and other
essential auxiliaries. It is assumed that means are available at all
times to start the emergency generator or one of the main generators
when the main source is arranged according to paragraph 12.7.2.
Where the emergency source of power is an emergency generator
which complies with section 12.4, or a main generator meeting the
requirements of paragraph 12.7.2, it is assumed that means are available
to start this generator and, consequently, this generator may be used
for restoring operation of the main propulsion plant and auxiliaries
where any power supplies necessary for engine operation are also protected
to a similar level as the starting arrangements.
Where
there is no emergency generator installed or an emergency generator
does not comply with section 12.4, the arrangements for bringing main
and auxiliary machinery into operation should be such that initial
charge of starting air or initial electrical power and any power supplies
for engine operation can be developed on board the craft without external
aid. If for this purpose an emergency air compressor or electric generator
is required, these units should be powered by a hand-starting oil
engine or a hand-operated compressor. The arrangements for bringing
main and auxiliary machinery into operation should have a capacity
such that the starting energy and any power supplies for engine operation
are available within 30 min of a dead craft condition.
