1 Where the electrical power is normally supplied
by more than one generator set simultaneously in parallel operation,
provision of protection, including automatic disconnection of sufficient
non-essential services and if necessary secondary essential services
as defined in the unified interpretation of SOLAS regulation II-1/40 and 41 above (Interpretation 2) and those
provided for habitability, should be made to ensure that, in case
of loss of any of these generating sets, the remaining ones are kept
in operation to permit propulsion and steering and to ensure safety.
2 Where Administrations permit electrical power to be
normally supplied by one generator, provision should be made, upon loss of power, for
automatic starting and connecting to the main switchboard of stand-by generator(s) of
sufficient capacity with automatic restarting of the essential auxiliaries, in
sequential operation if required. Starting and connection to the main switchboard of
one generator should be as rapid as possible, preferably within 30 seconds after loss
of power. Where prime movers with longer starting time are used, this starting and
connection time may be exceeded upon approval from the Administration.
