During an FMEA Proving Trial, the WCF (Worst Case Failure) is physically triggered while the vessel is in DP mode. What should the trial demonstrate?

A. That the WCF immediately causes a blackout and the vessel must be manually restarted

B. That the DPO can manually recover the vessel without using any automated DP features

C. That the alarm system activates correctly; position maintenance is not required during proving trials

D. That after the WCF occurs, the remaining redundant systems can maintain the vessel's position within acceptable limits — the vessel must not lose control of its position, and the DP system must automatically respond as the FMEA predicts

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
