During an annual DP trial, a failure mode occurs that was not anticipated or listed in the vessel's current FMEA. What should the DPO and Master do?

A. The DPO can add a note to the FMEA without involving the classification society

B. Report the discrepancy to the classification society and the DP system manufacturer; the FMEA must be reviewed and potentially updated to incorporate the new failure mode — operations in critical DP work should be deferred until the FMEA is revalidated

C. Assume the failure was an anomaly and repeat the trial to see if it occurs again

D. Log the event in the DP log and continue normal operations since the trial was otherwise successful

A. The FMEA is a voluntary best-practice document that the operator prepares for internal training purposes

B. The FMEA is a class-required document that systematically analyses each identifiable failure within the DP system and proves, by showing which failures are tolerable without loss of position, that the vessel has the redundancy claimed for its class notation

C. The FMEA is only required when the vessel changes DP class notation

D. The FMEA specifies the maintenance schedule for DP thrusters

A. The shipowner/operator commissions the FMEA, prepared by a specialist firm; it is reviewed and approved by the classification society as part of DP class certification

B. The DPO prepares the FMEA as part of their annual competency review

C. The flag state maritime authority prepares all FMEAs

D. IMCA prepares FMEAs directly for member vessels
