Alarm-pattern card — Turbine 7

Kit 9 · Turbine 7 · job aid for the control-room wall · one page, prints on A4 · fictional case, illustrative figures

Before any restart after an alarm, name the pattern and the evidence that puts it there. If you cannot name it, hold or escalate.

The four patterns

Pattern	What you see	Where the evidence is	Call
Cleared with a logged inspection	Reading back inside the band and settling; someone was up-tower and wrote it down	Inspection card or work order on the part; the maintenance log	Restart. Hand over a watch item
External cause, turbine nominal	Trip from the grid or the weather; every turbine reading normal	Trip record; the sister turbines on the same feeder; the met mast	Restart. Nothing on the turbine needs a look
Rising trend, no inspection yet	The value is still climbing over the last 20 minutes; nobody has looked	The 20-minute trend, not the alarm text	Hold for inspection. Restarting or derating is the critical error
Fault came back after a reset	The same fault, reset once, back again	Reset history on the component log	Hold for inspection. A reset silenced it; it did not fix it

Three checks before you call it

Trend, not state. Open the 20-minute trend. Is it settling or still moving?
Who looked? Find the inspection record. "Cleared" with no name and time on it is not cleared.
Is it only us? Compare the sister turbines on the string. If they tripped too, the cause is probably outside the turbine.

When production asks you to run it

Give the number, the risk and the next step, in that order:

"Vibration is 4.8 mm/s against a 2.0 baseline and still climbing. If the gearbox goes, that is a jack-up vessel and weeks, not a night. The inspection is booked for first light."

Not the rulebook ("policy says no"), and never "I'll restart and keep an eye on it".

Escalate when

the evidence points two ways (for example, a cleared alarm whose trend has started to rise again);
the call is outside the escalation boundary agreed with the shift leads;
you have held and the pressure continues.

Write it in the handover

The call, the reading or log entry that decided it (with its number or time), and what happens next (who, when).

Figures are illustrative. This card summarises the patterns practised in the Turbine 7 simulator; it does not replace the OEM's alarm procedures or your site's escalation boundary.
