NT-24-01: National Outer Continental Shelf (OCS) Oil Spill Occurrence Rates

closed

The overarching goals of this study are 1) to update oil spill rates of OCS platforms, OCS pipelines, and U.S. barges, 2) to obtain oil spill information for BOEM’s Offshore Environmental Cost Model (OECM), 3) to analyze oil spill trend and casual factors. Having updated oil spill and oil spill occurrence rate data is critically important to analyze the potential risk and consequence of OCS oil spills, investigate causal factors contributing to the occurrence, size or frequency of oil spills, enhance oil-spill response planning, and target future regulatory reform to better manage risk. Specific objectives are: Compilation of oil spill data and QA/QC of the data Examination of historical spill occurrences and of volume of oil handled Analysis of other potential exposure variables Estimate spill occurrence rates and normalize these rates based on number of spills per volume handled and other potential exposure variables Analyses on oil spill trend and casual factors Provide information for OECM model Prepare a 508 compliant report according to BOEM’s specifications.
