The only confirmation we have of this large spill
is an LA fire department list
which includes a 19750304 fire on the Oswego Patriot
at Berth 241 attributed to welding.
Mentions Sumatran crude.
Presumably this occurred while the ship was repairing
after the first casualty.
Ship is probably the ex-Borgila, believed to be 51,576 dwt.
The USCG Marine Board of Investigation
did NOT do a report.
Suspect OSIR spill volume may be hiogh.
