This was a bunker barge, not a lighter.
USCG says explosions in No 2 and No 3 cargo tanks, cracks in side shell plating.
Puts spill at 200B of cargo (BFO).
How in the world did these idiots
generate a tank explosion with BFO?
Was 3P a segregated ballast tank.
Maybe the bunkers still had some light ends.
Was the ship inerted?
Need more info?
