Title: what does physically being there get you that instruments don’t? (cs student question)
been going down a rabbit hole reading about inspection work — NDT, confined space entry, all of that. keep running into the same thing I can’t figure out.
sensors, cameras, ultrasound, drones — all of it exists. but at some point someone still has to go in. and from what I can tell it’s not always a reach problem. sometimes the equipment gets there fine, the data comes back, and a person still has to go in anyway because the data alone isn’t enough to make the call.
is that right? or am I reading this wrong?
I’m a cs student and this is something I’m genuinely working on — not a class assignment. what got me into it was reading about confined space incidents. people going into tanks with bad air, divers in conditions that ground everyone else, inspectors on ropes in spaces that had no business having a person in them. every time I traced back why the person had to be there, it kept coming back to the same thing. I want to understand that thing.
whether you’ve been doing this 3 months or 30 years — what have you personally run into where the remote data wasn’t enough and you had to go in yourself? what did being there get you?
any context welcome. I’ve been reading about UT on jet engines, storage tank floor inspection, underwater bridge work, LNG vessel spaces. but nothing beats hearing it from someone who’s actually been in these spaces.
this isn’t about replacing inspectors. the judgment that comes from doing this work is exactly what I’m trying to understand. I just keep thinking about whether the people going into genuinely dangerous spaces to confirm something already half-known have to keep doing that forever.
Edit:
Thanks all of the feed back helped immensely. If you have any feed back or something I can learn. Feel free to add comment it
-Really grateful
