Well said.
In an earlier discussion in this thread, I tried to bring to the table a little bit of my experience in overseeing commercial diving operations in the oil&gas industry, including jobs performed by Rockwater (not Rockwell

), and indeed I identified one of the divers involved in the Estonia job whom (it turns out) I know personally/professionally. So I would modestly claim to have a reasonable knowledge of how a commercial diving operation works, in terms of defined scope, hazard management, and recording/reporting, albeit not in a salvage-type operation like the Estonia - which, it must be said, is pretty harrowing for the dive team, to be digging around dead bodies. The individual diver that I am acquainted with, is no 'snowflake' (I hate that term), but is ex-SAS, so he's been around plenty deaths and grim situations.
However, some participants think they know better, because they can Google or ask AI for the definition of a hull! 'Think about it'.
