Alert Intelligence
Alarm flood collapsed into causal chains. One root cause, one decision — not hundreds of independent alarms.
Hydraulic System Failure
Loop B pressure 118 bar (min 160)
Bow Thruster 1 Degraded
Pitch response limited to 62%
DP Capability Reduced
Capability index 71% → 58%
Mission Risk Increased
Loss of position risk +11%
Isolate hydraulic loop B, transfer bow thrust demand to tunnel thruster 2 and reduce heading offset to 320° to unload the bow.
