DP FMEA - Single-Fault Post Capability
DP Class 2/3 single-fault post-capability check - verify that after any single failure the vessel still holds position in the environmental envelope.
Thrust margin (post-WCF − env)
300kN
Status
Compliant
Formula, assumptions, and limits
DP Class 2 redundancy covers active fault of any component. DP Class 3 adds fire / flood protection - requires dual switchboards + cable routing. Verified via annual FMEA trial.
