Consequences of Failure Modeling for Oil and Gas Spills

The failure of subsea pipeline system may bring a lot of trouble to the environment, biological health and the economical costs. In order to prevent the pipeline failures, Quantitative Risk Assessment is employed to evaluate the risk and failure consequences. This chapter focus on the determination of oil spill slicked and gas spill leakage when a leak occurs in a pipeline system. The main mechanisms of oil spill, oil spreading and oil evaporation are reviewed. Risk assessment is used to evaluate the integrity of a pipeline system to avoid any consequences resulting from pipeline failures which related to personnel, environmental and production capacity, and the failure consequence categorization for each area was ranking from A class to E class.
