Table 7:
Scenarios for anticipated oil spills from a 30-inch pipeline, transmitting
at 300,000 barrels per day.
Scenario No.1 (minimum case):
-
Elapsed time between rupture and total shutdown is 5 minutes.
-
90 percent of crude oil remains in pipeline.
-
Rupture is one miles below nearest upstream block-valve.
LOSS = 540 barrels
Scenario No.2 (intermediate case):
-
Elapsed time between rupture and total shutdown is 10 minutes.
-
50 percent of crude oil remains in pipeline.
-
Rupture is 9 miles below nearest upstream block-vale.
LOSS = 21,591 barrels
Scenario No.3 (maximum case):
-
Elapsed time between rupture and total shutdown is 20 minutes.
-
10 percent of crude oil remains in pipeline.
-
Rupture is 18 miles below nearest upstream block-valve.
LOSS = 77,729 barrels
