The Chief Engineer proposes running closed bus during a routine DP2 operation to improve fuel efficiency, noting "it's only a minor operation, not deepwater drilling." What should the DPO/Master consider before agreeing?

A. Agree immediately, since fuel savings benefit the operator and the operation is described as minor

B. Whether the vessel's approved ASOG and FMEA permit closed bus operation for this class of activity, and whether the consequence of a single-point electrical fault under closed bus has been properly assessed for this specific task — fuel efficiency does not override the documented redundancy basis for the operation

C. Defer entirely to the Chief Engineer since electrical configuration is an engineering decision outside the Master's authority

D. Closed bus is never permitted under any circumstances on a DP vessel

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
