MOVE your SUPER-TANKER out of my DEEP-WATER PORT, page-43

I don't know kit, I think 293 bopd through a 12/64 choke is pretty good, not being an oil field guru like some here.... I assumed we're talking good ole us imperial inches.. About 0.2 of an inch... Kinda bic Biro tube.
An inch for non baby boomers here is 2.54 CM... Call it 25mm doo dee doo divide by 64 multiply that by 12 about 4.5 mm. Drinking straw, so they've got that choked back alright.
Now is that due transport and storage constraints.... Or is because the pressure drops off if they open it up?
