I guess it might work if shipping company is non-Western (such as Chinese or Russian) - but I’m not sure what the advantage of bitcoin is in that case, as opposed to simply paying in yuan or rubles
I'm curious what makes your think these ships are unknown. There are 2 blockades in place and suspicion of mines in the conventional shipping route through Omani controlled waters.
Whereas if it's not traceable then all that others know is that your ship got through the strait and there's at least some plausible deniability of why it got through
