During a complex multi-fault DP scenario, a DPO silences all alarms simultaneously to "clear the panel" before beginning diagnosis. A few moments later the vessel starts to drift. What went wrong and what should have been done?

A. The DPO should have called the Master before silencing any alarms

B. By silencing all alarms before reading them, the DPO eliminated the system's ability to signal a position-critical alarm — the drift warning may have been among the alarms silenced. Correct procedure is to triage before acknowledging, reading and categorising each alarm before silencing any

C. Nothing went wrong — silencing alarms is the correct first step in any multi-alarm scenario

D. The fault was in the alarm system, not the DPO's response

A. The classification depends on who set the alarm, not on the severity of the condition

B. All DP alarms are treated equally — they all require the same response

C. DP alarms only have two categories: operational and engineering

D. High-priority (Category 1): requires immediate action — position-critical failure or imminent risk; Medium-priority (Category 2): requires prompt attention — reference degraded, thruster fault; Low-priority (Category 3): advisory — condition monitor, early warning. Each category drives a different urgency of response

A. Alarm flooding occurs when the alarm speaker volume is set too high

B. Alarm flooding only occurs in integrated bridge systems, not standalone DP consoles

C. Alarm flooding is beneficial because it ensures the DPO is alerted to all conditions simultaneously

D. Alarm flooding occurs when multiple alarms activate simultaneously or in rapid succession, overwhelming the operator's ability to diagnose the root cause — in DP, this can mask the critical alarm that actually predicts position loss, causing the DPO to miss the most important signal among the noise
