Here's how the Calculator should
look, once you've entered information about the ACRU2 (Questions 4 and 5):

Answers
- About how much oil could the Sandpiper
recover during the operational period? Your best estimate of this amount is
the amount of oil and emulsion recovered ("Oil/emul. recov."), which is 15
barrels. Because some of this volume is water mixed with oil in an emulsion,
this number may be an overestimate.
- What percentage of the total volume
of the slick is this? This is the amount of oil and emulsion recovered, 15
barrels, divided by the total amount in the slick, 1000 barrels, multiplied
by 100%: (15 bbl/1000 bbl) * 100% = 1.5%
- Is skimming with the Sandpiper
a realistic option, given the time you have available? By skimming with the
Sandpiper, you would be able to recover only a very small amount of the spilled
oil. Using this response option may not be worth the expense.
- What if you also were able to
assign the ACRU2 to help skim the slick--about how much oil could the two
platforms recover during the operational period? Your best estimate is the
sum of the amount of oil and emulsion recovered by each platform: 415 barrels
+ 15 barrels = 430 barrels of oil and emulsion.
- About what percentage of that
oil would be skimmed by the ACRU2? This is the amount recovered by the ACRU2,
415 barrels, divided by the total amount recovered, 430 barrels, multiplied
by 100%: (415 / 430) * 100% = 97%.
