Oil-spill risk analysis: Outer continental shelf lease sale 144, Beaufort Sea. Final report

The Federal Government has proposed to offer Outer Continental Shelf lands in the Beaufort Sea for oil and gas leasing. Because oil spills may occur from activities associated with offshore oil production, the Minerals Management Service conducts a formal risk assessment. In evaluating the significance of accidental oil spills, it is important to remember that the occurrence of such spills is fundamentally probabilistic. This report summarizes results of an oil-spill risk analysis conducted for OCS Lease Sale 144, Beaufort Sea. The objective of this analysis was to estimate relative risks associated with oil and gas production for the proposed lease sale.
