Oil spill occurrence estimates were generated for several expected future oil and gas development scenarios (including exploration, production, and abandonment) in the Beaufort Sea Offshore Continental Shelf (OCS) lease sale regions. Because sufficient historical data on offshore oil spills for these regions do not exist, an oil spill occurrence model based on fault tree methodology was developed and applied. Using the fault trees, base data from the Gulf of Mexico including the variability of the data, were modified and augmented to represent expected Arctic offshore oil spillage frequencies. Three principal spill occurrence indicators, as follows, were quantified: § Spill frequency
