More so than I think any other PSD, you need a whole bunch of surface support on hull searches - line tenders and the like (which gets into your SOPs - bite reg scuba with a tether [only practical way to do a full or half necklace really]? AGA with hard line coms and scuba, surface supply AGA?), but that ship must be properly tagged out, which means a dive sup who knows something about ships and whoever pases for a ship's engineer have to physically turn off everything under that ship (not always possible, but usually a half of a large ship at a time can be tagged out) and place tags or locks (or people) on whatever switch or lever turns that stuff back on.
Lots of things under big ships can kill divers.
That thick red marine paint on most navy and commercial ships is also toxic. It sloughs right off when touched.
