[QUOTE=ForkandBlade;93199]That isn’t a dumb question at all. Most of the engineers on tugboats, that I know of, don’t have any kind of PIC. Maybe it has something to do with the act of fueling and it not being cargo? Probably could find the answer on the NMC’s website, by pulling up the different tankerman endorsement checklists and looking up CFR #s referenced.[/QUOTE]
See 33 CFR 155.710, in particular paragraphs (e)(1) and (e)(2).
You won’t find it on NMC’s web page (or shouldn’t) as it a manning/compliance issue that is beyond NMC’s responsibilities and expertise.
