  • OFFSHORE Arctic Pipeline OIL SPILL RISK ASSESSMENT
    2004 International Pipeline Conference Volumes 1 2 and 3, 2004
    Co-Authors: G. Comfort, A. Dinovitzer, R. Lazor, D. Hinnah
    Abstract:

    Renewed interest in offshore Arctic oil and gas has led to the need for Pipeline designs able to minimize environmental risk. A risk evaluation was conducted to assess the relative merits of Pipeline concept designs for the Liberty Pipeline, which is intended to carry oil from BP/Amoco’s Liberty site to onshore Alaska. The Liberty site is inshore of the Barrier Islands in the Alaskan Beaufort Sea, in 22 feet of water. The offshore portion of the Pipeline is 6.12 miles long. Risk was defined as the oil volume expected to be spilled over the 20-year life of the Liberty Pipeline. Risks due to ice gouging, strudel scour, permafrost thaw subsidence, thermal loads leading to upheaval buckling, corrosion, third party activities, and operational failures were evaluated. Failure probabilities were assessed based on analyses of the Pipeline’s response and failure criteria that were established. A consequence model was set up to quantify the oil volume released during a Pipeline failure, considering the mode and location of failure as well as leak detection systems. The risk was evaluated by summing the product of event probability and consequence for each hazard. The relative risk is discussed for each Pipeline design.Copyright © 2004 by ASME

  • offshore Arctic Pipeline oil spill risk assessment
    ASME 2004 23rd International Conference on Offshore Mechanics and Arctic Engineering, 2004
    Co-Authors: A. Dinovitzer, G. Comfort, R. Lazor, D. Hinnah
    Abstract:

    While offshore Arctic Pipelines have been under consideration for more than 25 years, few have been built. Renewed interest in offshore Arctic oil and gas has necessitated the design of Pipelines capable of both overcoming the technical challenges of the Arctic offshore environment and minimizing the risk to it. This paper describes a quantitative risk assessment completed by BMT Fleet Technology Limited on the risk of an oil spill for several design alternatives of the proposed Liberty Pipeline that would be used to transport oil onshore from a production site in the Alaskan Beaufort Sea. For the purposes of the study, risk was defined as the volume of oil expected to be released over the planned Pipeline 20-year life. The investigation considered the risks associated with ice gouging, strudel scour, permafrost thaw subsidence, operational failures, corrosion, third party activities and thermal loads leading to upheaval buckling. Event probabilities for these hazards were established through the development of event trees used to combine historic operational failure statistics and those estimated through engineering analysis. A Pipeline leakage consequence model was developed to quantify the oil volume released during Pipeline failure events associated with rupture, through-wall cracking and pinhole leaks. The model considered secondary containment and the expected performance of leak detection and monitoring systems. The time to leak detection, shut down, and line evacuation were used in estimating the total spill volumes. The paper provides an overview of primary elements of the risk assessment including the hazard identification, reliability analysis and consequence modeling, and describes the challenges involved in this comparative risk analysis completed for this unique environment.Copyright © 2004 by ASME
