AquaeSulis01,
"Now if you use the 158.897 litres per barrel figure you get 503186 barrels (1000/158.897*80000) whilst using 7.33 barrels weight you get 586400 barrels (7.33*80000), what isn't in doubt is the load is over 500000 barrels"
OMG. Have I got it wrong again? Earlier I wrote "somewhere between 520,000 bbl and 555,000", somewhat high-handedly correcting DiveCentre's 600,000 or more.
But now you've come up with a figure higher than mine!
However, it all revolves around this (your quote).
" (on average) 7.33 barrels weigh one metric ton "
And you've got me onto google again, trying to figure out what that word 'average' means in terms of crude. But the one finds oneself chasing one's own tail, 'cos you've got 'average densities' for light, medium, and heavy crudes!
Now I suspect that an imaginary statistician who knows nothing about crude oil would argue that to find an 'average density' it's best to use 'medium', or 'average oil'. But we know that Lancaster crude is 'light'. And my (memorised) 'rule of thumb' calculation is based on some early 'thirties thing regarding California, whose crude is generally heavier.
So I don't know, exactly.
If we say something between 520,000 and 600,000 bbl for the recent load, does that keep everyone happy? Except for the Chuckle Brothers, that is. ;-))
Btw, enormous gratitude to Missdosh for posting the link. But usually it's best for the truth to be out in the open. The only people who suffer are the shorters and derampers.
