Alternative Oil Spill Occurrence Estimators and their Variability for the Alaskan OCS Fault Tree Method (Update of GOM OCS Statistics to 2006); Final task rept

摘要

Historical data and their statistical analyses are used as a starting point for fault tree application to oil spill indicator quantification for the Alaskan OCS. In the initial fault tree analysis, data from the GOM OCS were analyzed for the period from 1972 to 1999. Subsequently, a more refined publication of the data characteristics by MMS has made it possible to conduct a more thorough statistical analysis as well as an update of the data and its analysis to 2006. This report generally discusses and gives data summaries as well as detailed statistical results for the re-analysis of the data, including an update of the GOM OCS data for platform and pipeline spills, including an update to 2006.
