Hey fuckheads! Ever hear of "engineers"? No.
Seattle has wasted several weeks of downtime and hundreds of hours of expensive labor under deep sea diving conditions on its Big Bertha tunnel borer. After the expensive inspection, it turns out the cutting heads were clogged.
Clogged.
Cutting heads clogged.
Cutting heads full of rock and dirt.
I'm trying to absorb this, but not succeeding.
Dentists solved this problem 120 years ago.
Machinists solved this problem 100 years ago.
Closer to the point, oil drillers solved this problem 80 years ago.
Didn't the builders of this hugely expensive monster THINK about the possibility that a cutting head might get clogged? Didn't they ASK if this problem had been solved before? Didn't they at least put stress gages and thermocouples in appropriate locations to DETERMINE if the problem occurred? No, they obviously didn't.
