Maritime Questions › DP — Power Management System
Before a generator overload escalates to a total blackout, what layers of PMS protection are typically designed to intervene first?
A. 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
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. There are no intermediate layers — any overload immediately causes blackout

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 only logs fuel consumption for reporting purposes
D. 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

A. It refers to manually unloading cargo to reduce vessel draft
B. 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
C. It means switching all power to the emergency generator during normal operations
D. It is a planned maintenance activity to rotate generator running hours
