## Design premise

Every scene is a decision with a consequence, not a slide. The learner works one night shift from the operator's desk; the turbine, the string and the sea are where the evidence lives. The 2D simulator and the 3D scene read the same case file (`scenarios.js`), so the cases, scores and feedback are identical in both.

## Shift structure

One shift = four alarm cases, **one per pattern**, drawn from a bank of eight (two per pattern) and dealt in a random order. Each case has four steps:

1. **Look.** Open the part the alarm points to, or anything else: the other drivetrain parts, the met mast, the sister turbines. The call stays locked until the part holding the deciding evidence has been opened.
2. **Call.** Restart, Restart derated, Hold for inspection, or Escalate to the shift lead. The consequence plays out on the machine.
3. **Pattern.** "Which input decided this case?" Four options, shuffled, scored separately.
4. **Pushback.** On rising-trend and recurrence cases, if the learner held or escalated, the production desk radios in; the learner picks a reply.

The shift ends with a **handover note** (LO3, formative) and the debrief.

## Frames

![F1 · 23:15, the operator's desk. The alarm list, the 20-minute trend and the string map are on the three monitors; the CCTV wall shows the farm live. The clock and the window match the case time.](/work/turbine-7/screens/frames/f01-desk-alarm.webp)

![F2 · The CCTV wall. A live render from T-06's nacelle camera of T-07 and the string, in the case's weather: rain and 2.6 m waves on the windiest night of the week.](/work/turbine-7/screens/frames/f02-cctv-wall.webp)

![F3 · String B from above at night. Aviation lights blink in sync on every nacelle; yellow navigation lights mark each platform. T-06 and T-08 are labelled because they share T-07's feeder.](/work/turbine-7/screens/frames/f03-string-night.webp)

![F4 · T-07 at dusk (ALARM 087). The scale is real: 112 m hub height, 80 m blades. A GRP nacelle with rounded shoulders, bolted panel joints, louvred intakes, an open-frame roof cooler and a helihoist deck. The panel on the right carries every stop and part as a button, so nothing needs a mouse.](/work/turbine-7/screens/frames/f04-t07-dusk.webp)

![F5 · The roof hatches swing up and out between the shoulders. Main bearing, gearbox with its accelerometer, brake and the yaw ring are visible from above; the work lamp marks the part the alarm names (location only, never a verdict).](/work/turbine-7/screens/frames/f05-roof-open.webp)

![F6 · Evidence on the part (087, cleared). The day crew's inspection card is cable-tied to the generator housing: inspected 14:20, grease OK, no play, alarm cleared. People stay off-screen; their traces do not.](/work/turbine-7/screens/frames/f06-generator-card.webp)

![F7 · Evidence on the part (092, rising). The planetary-stage hatch is open; vibration is 4.8 mm/s against a 2.0 baseline and still climbing. There is no card here: nobody has been up-tower.](/work/turbine-7/screens/frames/f07-gearbox-hatch.webp)

![F8 · Evidence on the part (079, cleared). Work order WO-5512 taped to the forward converter cabinet's door and the clogged inlet filter, bagged on the floor in front of it.](/work/turbine-7/screens/frames/f08-converter-work-order.webp)

![F9 · Evidence on the part (094, recurrence). Seen through the open hub: the painted alignment stripe across blade C's root and its pitch bearing is broken, so the blade is not at full feather. On a healthy blade the stripe runs straight across. The pitch log shows the fault, the reset, and the same fault again.](/work/turbine-7/screens/frames/f09-blade-c-pitch-mark.webp)

![F10 · Evidence on the part (105, recurrence). The twelve yaw drives inside the yaw bearing carry their SCADA numbers, with the brake calipers between them; M3 is the one that tripped twice while turning.](/work/turbine-7/screens/frames/f10-yaw-motor-3.webp)

![F11 · External cause (110, storm). The front has passed; the met mast's anemometer and vane agree with T-06, and the sisters restart on their own schedule.](/work/turbine-7/screens/frames/f11-storm-met-mast.webp)

![F12 · Thermal view. A temperature scale on each part, with a number label fixed to the part (it moves and hides with it), not a colour verdict. It shows where heat is, not what to do about it.](/work/turbine-7/screens/frames/f12-thermal-view.webp)

![F13 · Consequence of a restart into a rising trend (092). Fast-forward: three days of running on the trend; the gearbox fails on day 3.](/work/turbine-7/screens/frames/f13-restart-day3-overheat.webp)

![F14 · Nine weeks later, in this case's figures. A jack-up vessel has jacked out of the water beside T-07 and its crane lifts the failed gearbox out through the roof.](/work/turbine-7/screens/frames/f14-jackup-lift.webp)

![F15 · Consequence of a hold (094). T-07 stays feathered; a crew transfer vessel brings the technician to the boat landing.](/work/turbine-7/screens/frames/f15-hold-ctv-landing.webp)

![F16 · End of shift. Score, critical errors, the handover note against its rubric with a model note, the four patterns stated once, and the transfer prompt for the next real shift.](/work/turbine-7/screens/frames/f16-debrief.webp)

## Case bank

| Pattern | Case | Where the evidence is | Best call | Critical error | Consequence in 3D |
|---|---|---|---|---|---|
| Cleared with a logged inspection | 087 generator bearing temperature | Inspection card on the generator | Restart | none | Returns to service with its sisters |
| | 079 converter cooling flow | Work order on the converter cabinet | Restart | none | Returns to service |
| Rising trend, no inspection yet | 092 gearbox vibration | Trend + no inspection on the gearbox | Hold | Restart, Restart derated | Restart: gearbox fails, jack-up lift. Hold: CTV at first light |
| | 098 main-bearing temperature | Trend + grease log on the main bearing | Hold | Restart, Restart derated | Restart: bearing seizes, jack-up lift. Hold: CTV |
| Fault came back after a reset | 094 blade C pitch fault | Pitch log + pitch mark on blade C | Hold | Restart | Restart: blade drifts, rotor trips. Hold: CTV |
| | 105 yaw motor 3 overcurrent | Yaw log on the yaw drives | Hold | Restart | Restart: nacelle stops following the wind, trips. Hold: CTV |
| External cause, turbine nominal | 101 grid-dip ride-through | Trip record on the converter + sister turbines | Restart | none | Rejoins the sisters; a hold loses €6,800/day |
| | 110 storm cut-out | Met mast + sister turbines | Restart | none | Rejoins the sisters; a hold loses €7,400/day |

## Production-desk pushback

| Reply type | Example (092) | Score | Feedback point |
|---|---|---|---|
| Data + risk + next step | "Vibration is at 4.8 against a 2.0 baseline and still climbing…" | 1 | The production desk can take that upward |
| Rule only | "Policy says I cannot restart above the alarm band." | 0 | Invites "then who can override it?" |
| Concede | "OK, I will restart and keep a close eye on it." | 0 | Undoes the safe call |

## Scoring and pass rule

Each case: call 2 / 1 / 0, plus 1 for naming the pattern; the two pushback cases add 1. Maximum 14. **Pass = 12 or more and no critical error.** The handover note is scored 0–6 against its rubric and shown in the debrief; it does not change the pass.

## Retry

"New shift" draws a new case from each pattern and a new order, so a retry tests whether the learner reads the evidence, not whether they remember the cases.
