DP — Power Management System Practice Questions

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

A. It is a control strategy that rapidly ramps up an idle or standby generator's output and brings it onto the bus faster than standard load-sharing logic, to respond to a sudden surge in thruster demand before the running generator(s) overload and trip

B. It refers to loading fuel onto the vessel more quickly during bunkering

C. It is only relevant to emergency generators, not the main power plant

D. It is a setting that allows generators to be started without warm-up procedures to save time
