here are some observations on your math, perhpas you will review your numbers:
3 tankers a week - what source do you have for that? - hearing from eye witnesses of multiple per day and who knows how many at night?
Multiple per day means say 15 per week x 8800 x 3.75 (more realistic price per gallon) = $500k per week, (I guess should really do for #6 oil per barrel but I get so frustrated by an industry that cannt settle on one unit of measure.)
As for 24x7 that is what they are running at - did you not read the 10K? explained there exactly what the running was - 24x7 with 36 hours downtime for maintenance a month - that includes cool down (16 hours) and warm up (8 hours).
So so long as there are multiple tankers a day AS REPORTED they are making $500k a week or $20m year allowing for downtime. from 2 processors or $10m per year from one.
