What does "blocking" a diesel generator from starting mean in a PMS, and in what circumstance might the DP team deliberately apply it?

A. It is a permanent setting that can never be reversed once applied

B. It prevents a specific generator from being automatically (or manually) started by the PMS — this might be deliberately applied if that generator is undergoing maintenance or has a known fault, so the PMS does not bring a defective unit onto the bus during an automatic response

C. It only applies to the emergency generator and has no bearing on the main generators

D. It means physically locking the generator room door

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
