Presume the USCG report is the final story.
No idea why it took them so long to figure out,
nore how a 264,000 gallon spill
could cause $267 million dollars in damage,
about $1000 per gallon.
The picture showed what looks like to be an elbow
in about a 3 ft diameter pipe.
Obvious questions: where did the pipe come from?
Why did no other ship hit this this object?
Another theory blamed an "11 ton, 13 ft prop
that fell of a COE dredge in April".
Cargo was said to be a "heavy Venezuelan crude"
No mention is made of whether the ship listed toward the damage or away.
Since oil was lost, normally it would have been away,
and the ship could have improved matters by ballasting on the side of damage.
