Before a generator overload escalates to a total blackout, what layers of PMS protection are typically designed to intervene first?

A. There are no intermediate layers — any overload immediately causes blackout

B. Only manual intervention by the engineer on watch can prevent blackout; the PMS has no automatic protection

C. The bus tie breaker is the only protection layer, regardless of generator loading

D. Fast load sharing to bring standby generation online, followed by automatic load shedding of non-essential loads, with the protective trip of the overloaded unit as a last resort that the system is designed to avoid triggering wherever possible

A. It is a manual logbook system maintained by the engineering officer

B. It exists solely to control hotel load (accommodation power), separate from DP thrust power

C. It automatically manages generator start/stop, load sharing, bus configuration, and load shedding to ensure sufficient power is always available for DP thrust demand, while protecting against blackout from overload

D. It only logs fuel consumption for reporting purposes

A. It refers to manually unloading cargo to reduce vessel draft

B. It is a planned maintenance activity to rotate generator running hours

C. It means switching all power to the emergency generator during normal operations

D. It is an automatic PMS function that disconnects pre-defined non-essential loads (or de-rates thruster demand) when generation capacity is at risk of being exceeded, preventing a generator overload trip that could cascade into a full blackout
