on subs this is normal even for diesel engines just because theres so little space
on conventional ships generally there's a bunch of panels that bolt down. you dont get the engine or parts for it through the normal doors and hatches. an entire piece of the ship gets unbolted and craned off before you can start major work. usually for above-water machinery rooms there will be similar panels for the walls. for example the AC units often are against a false wall that just comes off if you unbolt it (and then kills you if it wasn't supported beforehand because it's large enough to drive a truck through)
i cant find a good pic but if you ever go on a tour of a ship of any kind and see giant panels secured with fuckhuge bolts that are rusted to shit because they haven't been turnt since the keel was laid, that's what those panels are for. they go to spaces with big machinery you can't fit through the normal doors

idk about it being specifically the sides but submarines also have similar "an entire fucking piece of the outer shell comes off" feature. it's harder to see because ebin acoustic tiles cover it all up but those are just glued on and are designed to be "easily" replaceable. hit that shit with a heat gun and a prybar and they come off.

divers dont just go play in cooling pools for fun but iirc water is such a good radiation shield that the bigger risk is that despite being called "cooling" pools they are in fact quite hot
iirc off the coast of norway or iceland or something there's wreckage from a nuclear sub; iirc it's too deep to dive on but it presents no ecological issue. in fact the rusting metal and toxic substances inside the sub (battery acid, mulched russians, normal ass lube oils, people's untreated poop, etc) were considered a greater hazard.
