The project
You join Marlstone Process Engineering Ltd (simulated company)
You are the junior instrumentation engineer on the instrumentation package of a solvent blending tank. The plant handles flammable liquids, so the hazardous area classification, the instrument index and the safety function matter. You check a vendor datasheet, work out a level transmitter range, judge a calibration, and decide what to do when a calibrator is out of date. Later the client raises the throughput, a flameproof device turns out to be in the wrong gas group, a safety transmitter is found out of tolerance and the client asks you to re-issue a SIL the calculation does not support. The skill is to be exact, to write down what you found, and to be impossible to hurry past a safety rule.
The people in the story are roles, such as Lead Engineer, not real people.
