the 1966 build Idemitsu Maru was heavier (and overall bigger) than the 2014 build Dali;
Idemitsu Maru tonnage ~100,000 gt, load-capacity ~200,000 t
“Dali” tonnage ~95,000 gt, load-capacity ~110,000 t
this fixation on container ships is really weird, when you see how massive oil tankers already were 1972.
Im gonna die on that hill; they should have accounted for such events in 1972; it wasnt a “freak-accident” and it wasnt a “black-swan-event”, the pros saw it coming for quite some time and I bet that at least some people with the expertise saw it likewise 1972.
