Curious, isn’t it? It’s not like Singapore does much international trade with container ships.
The .gov has priced US Flagged ships out of the industry - be it ocean going or due to Jones Act. Great Lakes fleet is really the only one making that work I'm aware of.
TWIC cards too aren't helping. Expense and red-tape. I have mine so I can do what I want and need unescorted but I'm betting most foreigners haven't done the work and simply get escorted everywhere.
