8.7.2 Main source of electrical power

  .1 On units where the electrical power can normally be supplied by one generator, there should be provided suitable load shedding arrangements to ensure the integrity of supplies to services required for propulsion and steering and to ensure the safety of the unit. To cover the case of loss of the generator in operation, there should be adequate provisions for automatic starting and connecting to the main switchboard of a stand-by generator of sufficient capacity to ensure safe navigation when underway with automatic restarting of the essential auxiliaries including, where necessary, sequential operations. The Administration may waive this requirement in units where the power necessary to ensure the functioning of the services referred to in 5.1.1.1, except for services referred to in 1.3.14.2, is 250 kilowatts or less.

  .2 If the electrical power is normally supplied by more than one generating set simultaneously in parallel operation, there should be provisions (by load shedding, for instance) 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 underway.
