Having read enough plain crash stories, first thing I though of was material fatigue. Like in the early days fan blades snapping off jet engines causing catastrophic failure after so many takeoffs. Now they have to inspect these closely in manufacturing and during maintenance cycles. Wouldn’t surprise me if they use ML now as it seemed a difficult human observation task. The stress/unstress cycle of a vessel going that deep must be immense.
