A DP vessel has 12 alarms that have been inhibited continuously for three weeks because the faults causing them are "on the maintenance list." A new DPO taking over the watch discovers this situation. What should the DPO do?

A. Accept the situation — they have been inhibited by a colleague for three weeks so they must have been reviewed

B. Uninhibit all 12 alarms immediately regardless of the underlying fault conditions

C. Review each inhibited alarm to understand what condition it monitors and assess whether the inhibition is masking a current degradation in DP redundancy; escalate to the Master and Chief Engineer; if any inhibited alarm relates to systems affecting the WCF, consider curtailing DP operations until reviewed

D. Log the situation in the DP log and continue the watch without further action

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
