The objective of this study was to provide design options for Pipelines with regard to Arctic hazards such as strudel scour, upheaval buckling, and ice gouging in the Beaufort and Chukchi Seas. Design options included evaluation of PL configuration, material selection, design parameters, operating conditions, application of strain-based and limit state design methods. Design issues included construction, operations, integrity management, maintenance and intervention. Specific Tasks included: Perform Literature Review, Characterize Environmental and Operating Conditions, Conduct Hazard Assessment Perform Pipeline Mechanical Response Models (ABAQUS) Examine Pipeline Mechanical Performance Criteria Conduct Design Options Analysis Examine Design Options for Construction, Maintenance, and Repair. Provide Risk Analysis and Mitigation.
