DP Class 2 - Failure Envelope Capacity
DP Class 2 post-failure capability envelope - wind + current worst-case envelope after single fault per IMCA M140.
Post-fault thrust
1,680kN
Max wind speed withstand
52.9m/s
Formula, assumptions, and limits
Rough screening; full capability plot done via IMCA M140 with proper environmental loads. DP2 typically rated to withstand 60 kn wind, 2 kn current, 5 m H_s with WCF.
