8.8.1 The special requirements for the machinery,
boiler and electrical installations should be to the satisfaction
of the Administration and should include at least the requirements
of this section.
8.8.2 The main source of electrical power should
comply with the following:
-
.1 Where the electrical power can normally be
supplied by one generator, suitable load-shedding arrangements should
be provided to ensure the integrity of supplies to services required
for propulsion and steering as well as the safety of the unit. In
the case of loss of the generator in operation, adequate provision
should be made for automatic starting and connecting to the main switchboard
of a stand-by generator of sufficient capacity to ensure safe navigation
when under way and to ensure the safety of the unit with automatic
restarting of the essential auxiliaries including, where necessary,
sequential operations. The Administration may dispense with this requirement
for a unit where the power necessary to ensure the functioning of
the service referred to in 5.1.1.1,
except for services referred to in 1.3.17.2,
is 250 kW or less.
-
.2 If the electrical power is normally supplied
by more than one generator simultaneously in parallel operation, provision
should be made, for instance, by load shedding to ensure that, in
case of loss of one of these generating sets, the remaining ones are
kept in operation without overload to ensure safe navigation when
under way and to ensure the safety of the unit.
