Maritime Questions › DP — Power Management System
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. Closed bus is never permitted under any circumstances on a DP vessel
C. Defer entirely to the Chief Engineer since electrical configuration is an engineering decision outside the Master's authority
D. 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

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
