I wonder how thoroughly the various failure scenarios have been modeled and reported on. Something merely of the magnitude of the East Ohio Gas Fire [1] in a crowded port or canal would be awful, and I'm pretty sure a supertanker carries a lot more gas.
The industry has every incentive to do a careful job with the safety features of these ships and the terminals they unload into, but the trouble with ships is that things sometimes run into them... sometimes really big things.
It's a pretty awesome way to carry around a lot of portable energy, though.
