What I find interesting is that what everybody fails to mention is that the 795,000 litres is an original estimate that is likely to be extremely inaccurate. Every time an oil leak happens in this industry, the original numbers they come out with are always extremely conservative and misleading and wrong.
But let's take some time and entertain doing the math. One barrel of oil is equivalent to 159 litres.
https://en.wikipedia.org/wiki/Barrel_(unit)
The original estimate of 795,000 is obviously inaccurate. It is inaccurate because it sounds precise, but is misleading and far from it. If you look at the number itself, it is shown as 5,000 less than 800,000 and you think if they give such a precise number then you think it has been contained ... but if you do the math ... 795,000 litres/159 litres per barrel = you get EXACTLY 5,000 barrels. By this logic, 5,000 barrels of oil that fell out of a pipeline is not a precise number. I know I have heard this story before, so pay attention folks, there will be more to come on this story in the coming days as the industry tries to contain the PR nightmare just before the Nebraska decision is released.
Doing the math another way, a single barrel of oil measures 24" diameter x 35" high. Taking a radius of 12" and doing the math (12*12)3.1416 and 35" long we get a barrel volume of 15,833 cubic inches.
Now look at the pipeline. The diameter of a pipeline is 30". Using this same math, the cross sectional area of a 30" diameter pipe = 707 square inches. Dividing 15,833 cubic inches of oil in a barrel by 707 square inches of cross sectional area, we find that a single barrel of oil occupies a length of 22.4" of pipeline. Take this length of 22.4" per barrel and consider a 5,000 barrel spill, with barrels aligned top to bottom. That translates to an area of pipeline covering nearly 3 km in length, and it is probably safe to say that the actual spill amount is likely much larger based on history.
What I find interesting was that in the BP Horizon oil of spill of 2010 originally stated that the amount leaking was less than 1,000 barrels per day, but we now know that the amount that had been leaking was much, much more. Independent analysis put the original spill amount at an estimated 62,000 barrels per day, nearly 62 times more than the original declared spill amount:

So for arguments sake, say a company is able to contain a 5,000 barrel oil spill on land, how do you propose these companies will be able to contain a single tanker holding upwards of 2,000,000 barrels of crude oil located in BC's coastal waters, without completely devastating BC's pristine coastline? I am very open to hearing how you propose this should be done because I would love to be convinced otherwise.
