Know-how has always passed from hand to hand
Every plant, rig and vessel runs on things its people know and nobody wrote down. That knowledge has always moved from one person to the next: at the console, in practice rooms, through manuals. Each way works. Each leaves something behind.
At the console
The oldest way is to learn beside someone who already knows: an instructor at the console, the crew gathered round, the procedures open on the desk. Nothing teaches better. It reaches only the people in the room, and only for as long as that instructor is there.
In a replica
Where a mistake costs too much to make on the real thing, operators train on a copy of the control room. It is the closest thing to the real plant. It also means building the room twice, so few operations ever have one.
In the manual
What can be written down goes into manuals. The good ones explain how the equipment works, not only what to do. What they rarely hold is judgement: which reading to doubt first, or what the last crew tried when the usual fix failed. And a manual only teaches someone who opens it.
When the crew moves on
NASA’s Plum Brook reactor in Ohio went critical for the first time in 1961. For the next two years, two operators were on duty around the clock until it reached full power in 1963. It ran until 1973, when the nuclear rocket program was cancelled.
When NASA began taking it apart, a quarter century later, people who had worked there came back to help. What a crew learns on shift goes where the crew goes.
Where OTTO comes in
OTTO starts from the same things people always have: the documents, an engineer who knows the system, and practice on something that isn’t the real plant.
It turns your manuals, notes and one recorded walkthrough into training rooms. The engineer reviews and corrects them before any learner sees them. Operators then practise in the browser while OTTO asks about their reasoning, so what the engineer knows can stay with the crew after the engineer moves on.
