That shallow work is not dodging anything, it's the backbone of the whole Gulf operation. Those hull scrubs and inspections at 30 feet in murky green water are way harder than most deep dives if you ask me, zero viz plus tight spaces plus you're working the whole time instead of just floating down to look at something. 412 out of 500 sounds about right for someone who actually gets paid steady, the deep jobs are few and far between and half the guys chasing them are broke between gigs.

Replaced my whole dryer last year over what turned out to be a clogged vent hose, so I feel your pain. But that is not what the vent being clogged usually does. A clogged vent makes the dryer run hot and slow, it does not normally stop it from spinning or heating at all unless the safety switch kicks in. If it was really the vent, you probably had a thermal fuse blow too, which is a ten dollar part. Cleaning the vent fixed the airflow but the fuse is what got you running again, or you just got lucky jiggling wires. Check the fuse next time before you start shopping for a new machine.
