Just launch oil cans at the toxic barge to blow up the toxic barge.

THIS ANSWER IS FAKE!The only oil cans that are there are the ones that can KILL you. DUH!!

there are blue barrels near the toxic barge at the bottom of a long ship and ir you hold
the bite button on 1 of them and fling them at the barge(yu throw barrels at a big
explosive thing).
