Your typical WW2 tanker ran between 10,000 and 15,000 tons, with a few as large as 25,000 tons.  There is about 7 barrels of oil to the ton, so you are looking at somewhere between 70,000 barrels to 175,000 barrels per tanker.  Much of the oil in tankers that were sunk was refined products, chiefly gasoline (motor and higher octane aviation gasoline), diesel, and kerosene.  That tended to burn quite nicely when torpedoed.  The Japanese did use raw crude oil from some of the Indonesian fields that was of sufficient high grade to burn directly as boiler fuel, and did have problems with the accompanying vapor explosions, such as the one that destroyed the carrier Taiho.  Refined products are considerably less toxic than raw crude, which can range from high-quality West Texas oil to the high-grade sludge produced by Venezuela.  Raw crude contains the full spectrum of oil products in varying amounts, along with a host of contaminants such as sulphur, various metals, bromine, methane in solution, waxes of various kinds, etc.  A refinery is typically optimized to refine a given type of crude, and will actually produce more than a barrel of products from a barrel of crude as a consequence of the adding of hydrogen to the heavier high-carbon crude fractions to produce lighter fractions such as gasoline, kerosene, and diesel oil which take up a larger volume than the high-carbon fractions.

The tanker losses in WW2 were spread over the entire ocean area of the world, and over a period of 7 years, and occurred as one time events for the area the ship was sunk in.  Much of the oil was refined products.  What you have in the Gulf presently is a concentrated spill in both location and time, with continuous effects on the environment.  It is not a one-time event, but a continuous stream of oil hitting the wetlands, marshes, beaches, and ocean bottom.  Based on the Exxon Valdez spill, the long term effects are not going to be known for several years or possibly decades.  The Gulf ecosystems that are being effected by the oil are likely never to return to a pre-spill state, or if they do, it will be many decades in the future.

Very insightful thank you,

Are the airsoft rounds reuseable?

As a utility contractor I can offer a few tid-bits on this matter.

Volume, pressures and depth are no where near the same now as they were then. As tech progressed we got better at all three.  When you go surveying for for oil (or natural gas like I have experience with) they tend to progress together fairly evenly.  Since that site is about two miles under water that puts the other two categories proportionately high as well.

Also worth noting they have a 22 inch drill casing bellowing “peanut-butter textured” oil (or so I have read in trade magazines recently) into the gulf.  Up until the 70’ I think 2-1/2 or 3 inch casings were the standard.  Even if the casing was bigger say for example a five inch casing is was still reduces to 3 inches to go through the pump systems.  All fire engines still do this today.

(Not that this has come up so far but…)  I’m not sure when off-shore drilling became popular but even then we didn’t need to because of the number of land based oil sites at the time. So this factor can totally be eliminated from this equation.

As far as transporting goes a U-haul size box truck was the standard method of travel on land then not the 53 foot tractor-trailers we commonly see today.  Your container ships have evolved in much the same way.  So each loss would be marginally smaller. To put things into perspective the Exxon-Valdez oil spill in Alaska was estimated at 10.8 million gallons.

Lastly I think it should be worth noting that the demand for oil although great wasn’t like it is today.  Most US tanks at the time ranged 3-4 gallons per mile (not miles per gallon) and ran off of a 8 cylinder gasoline engine. When the US entered WWII we only had 15 modern tanks.

So every thing was at a much smaller scale then as far as harvesting and consuming oil goes.

Does it hurt -+ the same as getting hit with a paintball?

I would think it would hurt less since the round is smaller but on the other hand you could make the bed of nails argument.  One nail hurts since all that force is resting on one point but a bed of nails distributes the weight making it hurt less.

What say you?

I have never played airsoft.  Are their rounds reuseable?
