# Visual mock-ups & art direction — Turbine 7

> Kit 9 · Turbine 7 · deliverable · designed and built by I Wayan Usada · annotated renders from the shipped build · fictional case

## Direction

A North Sea night shift seen from the control desk, then from the machine. The place has to be believable at real scale (a 112 m hub, 80 m blades, a string of turbines 950 m apart) so that the evidence on the machine feels like evidence, not a quiz prop. The interface stays out of the scene: one panel, one strip of instructions, no labels on the machine except the ones a real turbine carries.

## Palette and light

- **Sea and sky change with the case.** Each alarm has its own time, sun height, wind, wave height, cloud and rain; the sky, sea colour, fog and reflections are recomputed from them. Night cases are lit by the moon, the aviation lights and the nacelle work lights.
- **Amber #ffb200 is the interface accent only** (panel edge, focus, primary button). Nothing in the scene is coloured good or bad before the learner commits.
- **Red appears in the scene only as real hardware**: aviation lights, the brake caliper, sensor housings.

## Type

A plain sans for the panel, monospace for readings, times and SCADA screens, the kit's serif for headings on the kit pages. Readings are text, never colour alone.

## Annotated key screens

![A · The desk. Three monitors carry the alarm list, the 20-minute trend and the string map, drawn live from the case. The CCTV wall is a real render of the farm, so its weather matches the case. The panel on the right is the only interface.](/work/turbine-7/screens/frames/f01-desk-alarm.webp)

![B · The machine at real scale. A GRP nacelle section with rounded shoulders and a tapered nose instead of a box; bolted panel joints, intakes and an access panel; a passive cooler you can see through; a spinner with blade openings. Textured paint, steel and plate (CC0 sets); one shadowed key light; fog and a far-sea skirt so the horizon is water.](/work/turbine-7/screens/frames/f04-t07-dusk.webp)

![C · The cutaway. The roof halves swing out like a real nacelle's service hatches, and the camera looks down through the opening. The work lamp says where the alarm points; it never says what the answer is.](/work/turbine-7/screens/frames/f05-roof-open.webp)

![D · Environmental traces. People stay off-screen; what they left behind is the evidence: a cable-tied inspection card, a work order, a bagged filter, a painted pitch mark.](/work/turbine-7/screens/frames/f06-generator-card.webp)

![E · Consequence at the scale of the vessel. A wrong restart is not a red cross; it is nine weeks and a jack-up vessel lifting the gearbox out.](/work/turbine-7/screens/frames/f14-jackup-lift.webp)

## Component decisions

| Decision | Why |
|---|---|
| Built in code at real dimensions | No CC0 model of an offshore drivetrain exists; building it means every part can be opened, labelled in the panel and scored |
| One panel, every action a button | Keyboard and screen-reader users can do everything the mouse can; on phones the panel becomes a bottom sheet and the camera reframes above it |
| Production desk as text radio calls | No synthetic voices or faces; the pressure is in the words and the €/day figure |
| Thermal view shows numbers | A heat map with a legend tells you where to look; a red/green overlay would answer the question for you |
| Quality switch (high / low) | Low drops real-time shadows, uses 512 px textures and lower pixel density; measured at 79 draw calls or fewer per view |

## Accessibility

Every stop and part is a button; the decision, pattern, pushback and note are form controls; readings carry text values and the trend has a text alternative. Reduced motion turns camera flights and time-lapses into cuts. If WebGL is unavailable, a poster and a link to the 2D version replace the scene. Full WCAG conformance needs testing with assistive technology, which has not been done.
