GENERATING SETS

Where only one generating set is normally to be in operation, there should be the provisions for automatic starting and connection to the main switchboard of a standby generator of sufficient capacity to permit propulsion and steering and ensure the safety of the ship in case of loss of the generating set in operation. Where more than one generating set is normally to be 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 one(s) are kept in operation without overload to permit propulsion and steering and ensure the safety of ship.
For non-automated vessels, the operational requirements of keeping two generators running in parallel operation while navigating in restricted water, may be considered as satisfying this requirement, provided that each of the generators is able to support the full electrical load during manoeuvring and in port transit. A declaration to this effect should be obtained by the Classification Society. Such declaration is to be re-endorsed at each annual machinery survey.
