This sounds an awful lot like survivorship bias.

It also sounded to me like dodging the question.

Giving them the benefit of the doubt, they're saying the biggest problem with submersibles is operator error. Of course it is, when the classing system effectively eliminates the majority of mechanical failures. That doesn't mean the classing system is failing, on the contrary, it means its working.

It is exactly survivorship bias: its taking the population produced by a selection filter (to wit, classing/certification) and assuming that the traits of that population are representive of what would exist without the filter.

Patent for their hull monitoring system: https://patents.google.com/patent/US11119071B1/en

Highly innovative! Instead of their sudden death being a complete surprise, they may have had a few awful moments of warning.

The engineer who worked on it said it would provide only milliseconds of warning before the hull collapsed. He was promptly fired.

Wouldn't they have communicated that back if they had?

There wasn't even an "Uh-oh", as far as we know.
